PADT is an engineering product and services company that focuses on helping customers who develop physical products by providing Numerical Simulation, Product Development, and 3D Printing solutions. PADT’s worldwide reputation for technical excellence and experienced staff is based on its proven record of building long-term win-win partnerships with vendors and customers. Since its establishment in 1994, companies have relied on PADT because “We Make Innovation Work.” With over 90 employees, PADT services customers from its headquarters at the Arizona State University Research Park in Tempe, Arizona, and from offices in Torrance, California, Littleton, Colorado, Albuquerque, New Mexico, Austin, Texas, and Murray, Utah, as well as through staff members located around the country. More information on PADT can be found at www.PADTINC.com.
When they walk into PADT’s main office in Tempe, Arizona, the first thing most people notice is our “wall-o-patents.” Over the years, PADT employees have been named on 43 patents. They range from fuel cell membranes to silicon wafer coating to a slew of medical devices. When we received notification that staff members were listed as co-inventor on two patients with numbers over 10,000,000 we thought it was a good excuse to celebrate the years of contributions our engineers have made.
The rich collection highlights the diversity of industries we work on and the ingenuity of our staff. When the companies who own the Intellectual Property (IP) represented on that wall came to PADT looking for assistance with research, development, troubleshooting, and testing of their products they found a partner that did more than carry out tasks. PADT collaborated with them to create novel solutions and approaches that resulted in IP.
You can view all of our patents on our wall… or on our patent page here.
We want to say thank you to our staff and our customers for letting us be part of their innovation.
This post is the thirteenth installment in our review of all the different products and services PADT offers our customers. As we add more, they will be available here. As always, if you have any questions don’t hesitate to reach out to firstname.lastname@example.org or give us a call at 1-800-293-PADT.
The development of medical devices is difficult. The regulatory challenges, quality requirements, and technical hurdles of dealing with the complex system that is the human body make the processes required to bring products for this industry to market unique and difficult. That is why PADT has a team in our Engineering Services department that is focused on one thing: Medical Device Development.
If you read our article on Product Development Services or watched the flashy video then you know how we do product development differently. That our processes and staff are proven, that we are all about solving problems and using project management intelligently, all geared towards to deliver a complete solution. Every one of those characteristis is true for our Medical Device team as well, we just add more on top to give our customers the confidence to work with us on their product development.
We sometimes get involved in projects all the way from defining specifications to coordinating with manufacturing. We also provide assistance at every step along the way: testing, concept modeling, trade studies, material evaluations, quality consulting, design for manufacturing, and testing to name just a few areas that we can help. That is one of the things that makes PADT unique in this particular industries. Most companies will only do the full product development, whereas we serve as an outside resource for the whole thing, or only where our customers need additional help.
Solving the Tough Problems
There are a lot of medical device design companies out there. We often get asked how we can stay busy in this industry, especially when we are not located in a hot-bed of device design and manufacturing like California, Boston, or Minneapolis. The answer is simple. Customers from those locations and other markets come to Tempe to work with us because we are good at solving the difficult problems. Most of this capability comes from the skill and experience of our staff. They know their stuff and they know how to systematically investigate and solve the most difficult problems. They also have access to advanced tools like 3D Printing and world-class simulation in-house. Combine this with solid project management and a well-provisioned lab, and you have a winning combination.
Understanding Medical Devices
The other key requirement for anyone doing medical device product development is a thorough understanding of Medical Devices themselves. Every industry has its buzzwords and acronyms, but medical devices are in a category all their own. They are a bridge between the world of mechanical engineering and medicine, so they terminology and operating environment are different then say aerospace devices or consumer products. To work on medical devices you have to understand all the physics, manufacturing, software, and electronics that every mechanical device needs. You also need to understand biology and treatment. PADT’s staff walks that fine line between the two worlds and often serves as a translator between the end user (doctors and nurses) and engineering, even within our customer’s organizations.
Quality is the most important, and least understood, unique aspect of Medical Device Product Development. Any team attempting to bring a product to market who does not know ISO 13485 and the FDA requirements will fail. We also know that Quality is a tool, not a barrier. We understand the client’s quality system and adapt our processes as efficiently as possible to get value from the entire quality process.
Let us Engineer your Medical Device Innovations
Here is a powerpoint we put together last year with even more information:
Product development for medical devices is something we are just plain good at. Large corporations and startups come to PADT to because we get the job done. You can see some great case studies here that tell the story in the words of our customers. Reach out to us via email (email@example.com) or give us a call at 480.813.4884 and we can talk about how our team can help engineer your medical device innovation.
Mostly we make boxes. Pretty boxes but the bulk of what we 3D Print is some sort of plastic box that people stuff electronics in to. Most of the time we also don’t really know what customers do with the objects we make for them. But every once in a while you get involved in a project that really makes a difference. That could not be more true than two recent medical applications for 3D Printing that we worked on with Intermountain Healthcare (IHC) in Salt Lake City, Utah.
KSL, a local TV station, did a story on our IHC was deploying 3D Printing to produce better outcomes for their patients. You can view the story here.
PADT was fortunate enough to be part of two of the cases mentioned in the story. The first was a St George man who was feeling some pain in his back. He had a scan and they found 12 kidney stones. On top of that, his kidney was not in the right place and was distorted. PADT helped print a model of the scan so that the doctors could just get a real feel for what they were dealing with, and then plan the surgery.
The second situation really pulled at our heart strings. A 10 year old boy needs heart surgery and its a complicated problem. They need a model fast so we worked with Stratasy to quickly print an accurate model so that the Top surgeons could come up with a plan. We still have not heard how it went, they are scheduling things, but the feedback from the team was that the 3D model was extremely helpful. We are talking life saving.
Both of these recent situations build on years of examples where we have worked the doctors and their technical assistance to convert scans of patients into usable 3D Models. If you are in the surgery or surgery planning space and want to learn more about how accurate 3D models printed directly from scan data can be used to improve patient outcome, contact PADT at firstname.lastname@example.org and we will connect you with our 3D Printing team.

The Wake Forest Institute of Regenerative Medicine (WFIRM) hosted about 400 attendees at the annual Biofabrication conference, held this year at Winston-Salem, NC (Oct 28-Nov 1, 2016). The conference included a 2 hour tour of WFIRM’s incredible facilities, 145 posters, 200 or so presentations and a small trade show with about 30 exhibitors. As a mechanical engineer attending my first bio-related conference, I struggled to fully comprehend many concepts and terms in some of the deeper technical presentations. Nonetheless, there was a lot I DID learn, and this post serves to summarize my thoughts on the four high-level insights I gleaned amidst the pile of information on offer. I hope these are of value to the larger community that is not on the front lines of this exciting and impactful area of research.
More than Organs
To say biofabrication is all about making organs is like saying manufacturing is all about making spacecrafts carrying humans to Mars. It misses a lot of the other valid human needs that can be met and suggests organs are the end of the biofabrication R&D curve, when they only represent one manifestation (arguably the most difficult one in our current sense of the world) of the application of the science. If we take a step back, biofabrication is fundamentally about “manufacturing with living materials” – in that sense, biofabrication blurs the lines between natural and man-made entities. If you could manipulate and engineer living cells in physical constructs, what all could you do? Here is a list of some examples of the different applications that were discussed at the conference:
Toxicology Studies – Organovo’s examples of skin, liver and kidney tissue being used to evaluate drug efficacy
Body-on-a-Chip – A solution to aid in pre-clinical work to study whole systems (a key regulatory hurdle) and potentially displace animal studies in the future
Tissues for Therapy – This could involve patches, stents and other such fixes of a therapeutic nature (as opposed to replacing the entire organ in question)
Non-Medical Applications – Modern Meadow is a company that is using biofabrication techniques to make leather and thereby help reduce our dependency on animal agriculture. Biofabricated meat is another potential application.
Functional Tissues and Organs – An interesting thought presented by Prof. Rashid Bashir is that replacing organs with matched constructs may not be optimal – we may be able to develop biological entities that get the job done without necessarily replicating every aspect of the organ being replaced. A similar thought is to to use biological materials to do engineering tasks. The challenge with this approach is living cells need to be kept alive – this is easier done when the fabricated entity is part of a living system, but harder to do when it is independent of one.
Full Organ Replacement – Replicating an organ in all its detail: structurally and functionally – WFIRM has done this for a few organs that they consider Level 1-3 in terms of complexity (see Figure 1). Level 4 organs (like the heart) are at the moment exceedingly challenging due to their needs for high vascularity and large size.
It Takes a Village (and a Vivarium)
Imagine this is the early 2000s and you are tasked with establishing a center dedicated to accelerating the progress of regenerative medicine. What are the parts this center needs to house? This was probably what Dr. Anthony Atala and others were working out prior to establishing WFIRM in 2004. To give you a sense of what goes on in WFIRM today, here is a (partial) list of the different rooms/groups we visited on our tour: decellularization, imaging, tissue maturation, bioprinting, electrospinning, lab-on-a-chip, direct writing, vivarium that cares for animals (mice, ferrets, sheep, pigs, dogs – beagles to be specific, and “non-human primates”) and a cleanroom for pre-clinical studies. Add administrative, outreach and regulatory staff. Today, about 450 people work at WFIRM and many more collaborate. Going into this conference, I was well aware this field was an inter-disciplinary one. The tour opened my eyes to just how many interdependent parts there are that make an end-to-end solution possible, some more interdisciplinary in nature than others and just how advantageous it must be to have all these capabilities under one roof dedicated to a larger mission instead of spread across a large university campus, serving many masters.
“I Have a Hammer, Where is the Nail?”
I will be honest – I justified my interest in biofabrication on the very dubious basis of my experience with 3D printing, a long standing interest in the life sciences that I had hitherto suppressed, and the fact that I am married to a cancer researching biochemist – bioprinting was my justification for finally getting my feet (close to a) wet (lab). I suspect I am not alone in this (support group, anyone?). When I described this to the only surgeon who entertains my questions, he accurately summarized my approach in the afore mentioned hammer-nail analogy. So, armed with my hammer, I headed to the biofabrication conference seeking nails. The good news is I found a couple. As in exactly two. The bad news? See the section above – this stuff is hard and multi-faceted – and there are folks with a multi-decade head start. So for those of us not on the front lines of this work or not in college planning our next move, the question becomes how best can we serve the scientists and engineers that are already in this field. Better tools are one option, and the trade show had examples of these: companies that make bioprinters (see Figure 2 below), improved nozzles for bioprinting, clean-room alternatives, biomaterials like hydrogels, and characterization and testing equipment. But solving problems that will help the biofabrication community is another approach and there were about 5-10 posters and
presentations (mine included) which attempted to do just that. What are some of the areas that could benefit from such peripheral R&D engagement? My somewhat biased feeling is that there is opportunity for bringing some of the same challenges Additive Manufacturing is going through to this area as well:
Design for Bioprinting: fully exploiting the possibilities of bioprinting – “in Silico” has made some progress with medical devices – a similar window of value exists for biofabrication due to the design freedom of 3D printing
Modeling: Biofabrication almost always involves multi-materials, often with varying constitutive behaviors and further are in complex, time-varying environments – getting some handle on this is a precursor to item 1 above
Challenges of Scale: This has many elements: quality control, cost, automation, data security, bio-safety. This is one of the key drivers behind the recent DOD call for an Advanced Tissue Biofabrication Manufacturing Innovation Institute and is likely to drive several projects in this space over the next 5-7 years.
Moral of the story for me: carry your hammer with pride but take the time to learn, ask and probe to find the pain points that are either already there or are likely to arise in the future, and keep refining your hammer with input from the biofabrication community – conferences are the best place to do this – IF you go in with that intent and prepare ahead of time identifying the people you want to talk to and the questions you wish to ask them – something I hope to be better at next time around.
The Rate-of-Progress Paradox
Finally, a more abstract point. From the sidelines, we may ask how far has the field of biofabrication come and how fast is it progressing? It is one thing to sift through media hype and reconcile it with ground realities. It is quite another to discover this conflict seemingly exists even in the trenches – there are several examples of transplanted biofabricated entities, yet there is a common refrain that we have a long way to go to doing just so. And that struck me initially as a paradox as I heard the plenary talks that were alternatingly cautious and wild – but on the very last day I started to appreciate why this was not a paradox at all, it is just the nature of the science itself. Unlike a lot of engineering paradigms, there are limits to efficiencies that can be gained in the life sciences – and once these are gained (shared resources, improved methods etc.), success in one particular tissue or organ may not make the next one progress much faster. Take Wake Forest’s own commonly used approach for regenerative medicine, for example: harvest cells, culture them, build scaffold constructs, mature cells on these constructs, implant and monitor. Sounds simple, but takes 5-10 years to get to clinical implantation and another 5-10 of observation before the results are published. And just because you have shown this in one area, bladder for example, doesn’t make the next one much faster at all. All the same steps have to be followed: pathways to be re-evaluated, developmental studies to be done – prior to extensive animal and clinical trials. The solution? Pursue multiple tissues/organs in parallel, follow each step diligently and be patient. Wake Forest seems to have envisioned this over a decade ago and I expect the coming decade will show a cascade of biofabrication successes hit us with increasingly boring steadiness.
Finally, we should all be thankful to the many PhD students and post-docs from all over the world putting in the bulk of the disciplined, hard work this field demands, most of them, in my opinion, at salaries not reflective of their extensive education and societal value. We should also spare a thought for all the animals being sacrificed for this and other research, even in the context of best veterinary practices – my personal hope is that biofabrication enables us to stop all animal trials at some point in the near future – indeed, this seems to be the only technology that can. Then we can truly say with confidence, that we have first and foremost, done no harm.
Thank you WFIRM, for a wonderful conference and all the work you do everyday!
The Arizone high tech community gathered in downtown Phoenix Wednesday night to celebrate the leaders in the Biotech community at the annual AZBio Awards. As the premier event of a very busy AZBio Weekthe audience was joined by key companies and investors from outside of Arizona as well. The winners showed the diversity and promise of what companies in the state have accomplished and what they plan to do in the future. Governor Ducey also stopped by to say a few words about the progress that the community has made. A list of the winners can be found at the bottom of this post with links to more information describing what they have done to make the world a better place.
Every year we are pleased to see more and more people that we work with take home the trophies provided by PADT. Once again we made the awards themselves using a combination of 3D Printing and traditional manufaturing.
As a bit of a humble brag, we had the pleasure of providing assistance to the following individuals, shools, and companies who were recognized:
Global Med was recognized as 2016 Bioscience Company of the Year. They have used PADT for prototyping and even low volume production of their innovative telemedicine solution. Their growth has allowed for the delivery of quality health car to places around the world that are ohterwise unreachable.
Salutaris MD won a Fast Track award for their device that treats wet macular digenerations. We are proud to have been involved at the very begining during prototyping and most recently as they prepare for clinical trials.
ASU’s Dr. George Poste received the 2016 AZBio Pioneer Award for Lifetime Achievement for the significant contributions he has made during his carreer. In addition the recipient of the 2016 Arizona Bioscience Researcher of the Year award was the ASU BioDesign Institute’s Stephen Johnston, PhD. The University in general, and the Biodesign Institute in particular, are long time customers and heavy users of ANSYS and Stratasys products proved and supported by PADT.
Paradise Valley School’sMarni Landry was recognized with the Michael A. Cusanovich Bioscience Educator of the Year. PV school district was one of th first High Schools to adopt 3D Printing into their STEM ciriculum.
In addition, we were very pleased to see that one of our awards will be headed to Washington with Kyrtsten Sinema who was recongnized for her efforts to promote BioTech and Arizona in congress. Rep Sinema represents the district that includes PADT’s main office in Tempe and has been one of our favorite politicians since her bi-partisisn and common sense efforts in the Arizona State Legislature.
And finaly, a shout out to one of the other Fast Track award winners, Beacon Biomedical. PADT is looking at Beacon as an Angel Investment oportunity and they are across the hallway from PADT StartupLabs at CEI in Phoenix.
A big congratulations to all of the winners. The Bioscience commnity in the state is growing and at or near critical mass. From High Schools to large corporations with everything in between, our local companies are making the world a better place through better health technology.
About 40 people joined us at CEI this Monday at the start of Arizona BioScience week for some blunt talk about Medical Device development for startups. It was a great crowd and the quesitons were almost as (OK, maybe more) useful as the talk.
The gist of the seminar was a look at what it really takes to develop a medical device. We talked about the FDA, ISO 13485, QMS’s and the very well defined process that all companies must follow. We also talked a bit about tansfering to manufacturing and shared some lessons learned.
September is here and it is a jam packed month of events, many of them related to BioMedical engineering. We are continuing with ANSYS webinars and talking about 3D Printing as well. See what we have below:
September 13: Salt Lake City, UT Manufacturing Promotes Innovation Summit

Is PolyJet MED610 truly biocompatible? And what does that mean anyway?
A couple of months ago, our product development team contacted me to see if I could 3D print them a small bio-compatible masking device that was needed for temporary attachment to an invasive device prior to insertion for surgery. That led me to investigate all the different bio-compatible materials we did have access to at PADT on our FDM (Fused Deposition Modeling) and PolyJet machines. Given the tiny size and high detail required in the part, I decided to opt for PolyJet, which does offer the MED610 material that is claimed to be biocompatible. As it so happens, we have an Objet Eden 260V PolyJet machine that has been dedicated to running MED610 exclusively since it’s installation a year ago.
We printed the mask, followed all the post-processing instructions per supplier recommendations (more on that later) and delivered the parts for further testing. And that is when I asked myself the questions at the top of this post.
I set off on a quest to see what I could find. My first stop was the RAPID conference in (May 2016), where the supplier (Stratasys Inc.) had a well-staffed booth – but no one there knew much about MED610 apart from the fact that some orthodontists were using it. I did pick up one interesting insight: one of the engineers there hypothesized that MED610 was not very popular because it was cost-prohibitive since its proper use required machine dedication. I then went to the Stratasys Direct Manufacturing (a service bureau owned by Stratasys) booth, but it turned out they don’t even offer MED610 as a material option for service jobs – presumably because of the low demand for this material, consistent with our own observations.
So I took a step back and began searching for all I could find in the public domain on MED610 – and while it wasn’t much, here is the summary of my findings that I hope help anyone interested in this. I categorize it in three sources of information: claims made by the supplier, published work on in vitro studies and finally, some in vivo animal trials. But first, we must ask…
What does it mean for a Material to be Biocompatible?
A definition by Williams (The Williams Dictionary of Biomaterials, 1999) is in order: “Biocompatibility is the ability of a material to perform with an appropriate host response in a specific application.” So if PolyJet MED610 is to be called biocompatible, we must ask – what application do we have in mind? Fortunately, the supplier has a recommendation.
MED610 was launched by Objet in 2011 (Objet was acquired by Stratasys in 2012) as a biocompatible material, ideal for “applications requiring prolonged skin contact of more than 30 days and short-term mucosal-membrane contact of up to 24 hours“. Stratasys claims that parts printed according to Objet MED610 Use and Maintenance Terms were evaluated for biocompatibility in accordance with standard “DIN EN ISO 10993-1: 2009, Biological Evaluation of Medical Devices-Part 1: Evaluation and testing within a risk management process. This addresses cytotoxicity, genotoxicity, delayed hypersensitivity, and USP plastic Class VI, which includes the test for irritation, acute systemic toxicity and implantation”. Unfortunately, the actual data from the biocompatibility study conducted by Objet have not been made publicly available.
It is important to remember that Stratasys publishes a “Use and Maintenance Terms” document that details the steps needed not just to clean the part after printing, but also on the proper setup of the machine for ensuring best chances of meeting biocompatibility requirements. These are published online at this link and include a 3 hour soak in a 1-percent NaOH solution, a 30 min soak in IPA and multiple water jet rinses, among other steps. In other words, the claimed biocompatibility of MED610 is only valid if these instructions are followed. These steps are primarily driven by the need to completely remove supports and any support-residue, but it is not clear if this is needed if a part can be printed without supports. Given such strong process dependencies, it is only to be expected that Stratasys provide a disclaimer at the end of the document clarifying that the users of their machines are responsible for independently validating biocompatibility of any device they make with MED610.
The next question is: have there been any relevant published, independent studies that have used MED610? In my search, I could only find two instances, which I discuss below.
Primary Human Cells Response (In Vitro)
In a recent (January 2016) study published in the Journal of Medical and Biological Engineering, Schmelzer et al. studied the response of primary human cells to four 3D printed materials in vitro: ABS, PC, PLA and MED610 – the only such study I could find. All samples instead went through a 100% ethanol brief rinse and were washed 5 times with de-mineralized water – this seems like a less stringent process than what the supplier recommends (3 hour 1-percent NaOH solution soak, 30 minutes IPA soak and 10 times waterjet blasting) but was designed to be identical across all the materials tested.
There were some very interesting findings:
Different cells had different responses:
MED610 had the most negative impact on cell viability for keratinocytes (epidermal cells that produce keratin) – and the only material that showed statistically significant difference from the control.
For bone marrow mesenchymal (stem) cells, a different effect was observed: direct culture on ABS and PC showed significant growth (7X compared to control) but MED610 and PLA showed no significant effect
Surface Roughness influences cell attachment and proliferation:
In agreement with other work, the authors showed that while rougher surfaces promote initial cell attachment, subsequent cell proliferation and overall cell numbers are higher on smoother surfaces. The MED610 samples had rougher surfaces than the FDM samples (possibly due to the use of the “matte” finish option) and could be one of the contributors to the observed negative effects on cell viability, along with the leached contents from the specimen.
Glaucoma Drainage Device (In Vivo, Rabbit studies)
The devices were printed on a Connex 350 PolyJet machine, after which the supports were removed from the devices with a water jet and “were repeatedly washed and inspected for consistency and integrity.” Tubes were attached with Silicone adhesive and the entire assembly was then “washed and sterilized with a hospital-grade hydrogen peroxide system before use”. The researchers did not examine the cellular and extracellular reactions in great detail, but did conclude that the reactions were similar between the MED610 device and the more standard polypropylene injection-molded device.
A short video recorded by some of the researchers as part of a Bioprinting course also provides some details into the 3D printing aspects of the work done.
In conclusion, the question I posed at the start of this post (Is PolyJet MED610 truly biocompatible?) is too simplistic. A process and a material together are not sufficient – there are procedures that need to be defined and controlled and further and more importantly, biocompatibility itself has to be viewed in the context of the application and the specific toxicity and interaction demands of that application. And that brings us to our key takeaways:
MED610 is only recommended at best for applications requiring prolonged skin contactof more than 30 days and short-term mucosal-membrane contact of up to 24 hours and there is no data to dispute the suppliers claim that it is biocompatible in this context once all recommended procedures are implemented
The work done by Australian researchers in using PolyJet MED610 for devoloping their Glaucoma Drainage Device in animal trials is perhaps the best example of how this material and the technology can be pushed further for evaluating designs and hypothesis in vivo when really fine features are needed. Stratasys’s FDM PC-ISO or ABS M30i materials, or other FDM extrusion capable materials like PLA, PCL and PLGA may be better options when the resolution allows – but this is a topic for a follow-on blog post.
More in vitro work needs to be done to extend the work done by Schmelzer et al., which suggests that MED610 potentially has leachables that do impact cell viability negatively. Specifically, effects of surface finish (“matte” vs “gloss”) and sterilization on cell viability is a worthwhile follow-on step. In the interim, MED610 is expected to perform well for mucosal membrane contact under 24 hours (and why this is a great technology for dental guides and other temporary in-mouth placement).
If you have any thoughts on this matter or would like to collaborate with us and take advantage of our access to a PolyJet printer that is dedicated to MED610 or other bio-compatible FDM materials, as well as our extensive post-processing and design & analysis facilities, please connect with me on LinkedIn or send us a note at email@example.com and cite this blog post.

“It is not just a trend, it is a Tsunami. One day you will wake up and see a giant wave headed your way, and that wave will be the Internet of Things!”
This was the opening line from a presentation given by the VP of sales for a major engineering software company. It got my attention because it wasn’t hype or hyperbole. He was just pointing out the obvious. Over the past two years the signs have been there. Smart devices will connected to the internet, and older devices will be made smart and then connected. Those that don’t, will no longer be competitive.
It is not all about smart thermostats. Far from it. I went to IoT world in San Jose last week and saw a lot of people scrambling to find their solution. And a few that found them. The best example was an older letter stamping machine, you can guess at the manufacturer, that plugged a modular device from Electric Imp in to their controller and boom – they were connected. Some back end programming and they now had a competitive IoT device.
It is time to define and execute on your IoT strategy
When we visit customers, we will often ask them what their IoT Strategy is. The answers vary from “we don’t really think our products have an IoT play” to existing products on the market. The focus in the media is on consumer IoT products, but the bigger push right now is for industrial Internet, where machines used in manufacturing, energy generation, raw material extraction, and processing are smart and connected.
Customers from consumers to other companies will be requiring the benefits of IoT devices as they look to replace older hardware. That is why every company that makes physical products needs to develop an IoT strategy.
PADT Can Help
We have been helping our customers define and implement their approach to IoT well, since before it was called the Internet of Things. From assisting semiconductor companies that make MEMS sensors to making smart medical devices we are plugged in to what is needed to make IoT work.
There you can find some basic information about how PADT is a more comprehensive and technically capable solution then most design houses that claim to have IoT solutions. We are uniquely qualified to make sure the “Thing” in your IoT strategy is designed and manufactured right.
We also published a series of articles in the Phoenix Business Journal that provide some fundamental background information on the Internet of Things and how to deal with the challenges it presents:
Simulation can play a big role in almost every aspect of making your IoT device development faster and more productive. PADT uses ANSYS, Inc.’s comprehensive Multiphysics simulation tool set to model everything from the chip to the embedded system software.

PADT talks a lot about synergy as a key strength and a key element of the value we provide to our customers. Our three departments, Manufacturing, Services, and Sales, are in constant communication, always leveraging one another’s expertise to solve problems. Strong internal relationships — a consequence of being under the same roof — precipitate easy and abundant information and resource sharing. Communication, paradigm, alignment, synergy: clear as day.
But what does any of that mean?
When a PADT product development customer meets us for the first time, he or she may be shown a slide that looks like this:
Strong bilateral communication among the Product Development, 3D Printing, and Analysis groups means that the project is enriched by contributions from experts across several fields, multiplying the value we add in the development process. For instance, the product will likely someday run into a sticky problem without a clear solution. PADT can attack it from multiple angles, such as design adjustment, finite element analysis (FEA) optimization, and the iterative testing of 3D printed prototypes.
Ok, but still: what does any of that mean?
A longtime customer of PADT’s product development group recently ran into an urgent problem without a clear path to a solution. Their manufacturing partner called them and said that a particular subassembly in their design will cost three times more than expected, which would raise the price of the product above the maximum the market would bear. PADT was presented with the problem: how do we reduce the subassembly cost by 66% while maintaining overall performance, and how do we confidently select a solution in under a week?
PADT’s three engineering groups jumped in to help.
The Product Development group held a brainstorming session and came out with two adjustments to bring overall cost down. First, the subassembly of three bonded unique steel parts would be replaced by a single injection molded plastic part. This change reduces component cost to within the target, but also significantly reduces the final assembly’s structural integrity.
Secondly, a plastic stiffener truss was added between components to mitigate the reduction in overall stiffness. This change adds a little assembly cost, but also significantly increases the final assembly’s structural integrity, which had been weakened by the first change.
The Analysis group conducted a series of FEA simulations, first to determine the increased bending under load and second to select a material to balance the conflicting requirements for stiffness, strength, and cost. After multiple simulation iterations, it was determined that Product Development had selected a permissible path forward and that a glass-filled polypropylene provides the best combination of the three parameters.
The 3D Printing group then printed the new design for qualitative “look and feel” testing and quantitative force/deflection study. The group was able to closely match the properties of the selected material from their collection of printable filaments and top-shelf industrial printers, reproducing even the fine details — subtle fillets, radii — that boost strength but are missed with lower quality printers. Through prototype tests, it was determined that Analysis selected an appropriate material and Product Development selected an appropriate design.
In the end, PADT was able to confidently select a solution to the customer’s unique cost problem in under a week. Thanks to the synergy of three groups — Product Development, Analysis, and 3D Printing — the customer was able to stay on schedule and enter the market at a relevant price.
