As we shared in our recent press release, PADT was invited to be one of nine companies presenting at the 2019 Commercial Vehicle Cleantech Challenge. We happily spent the day at the Colorado Governor's mansion talking and learning about how to make the road transportation of goods with large and small vehicles cleaner and more efficient. As one of nine companies presenting, PADT talked about our custom blower technology for hydrogen fuel cells.
We want to thank both the Colorado Cleantech Industries Association (CCIA) and the North American Council for Freight Efficiency (NACFE) for hosting such an informative event. We were able to meet people from across the energy and learn about their needs, and give them an opportunity to learn more about PADT.
You can find their blog post here.
Here are some pictures describing how our day went.
The building and grounds at the Colorado Governor's Mansion are truly beautiful. We spent most of the day in the carriage house in the garden... which I failed to get a picture of.
It was a packed day as can be seen from the agenda. And the list of sponsors was fantastic. We were able to talk with key industry visionaries for more efficient and cleaner commercial vehicle fleets.
One of my favorite things about the site were these very cool napkins they gave us. Nice seal. And, "Executive Residence" sounds so much classier than "the Gov's House"
We spent most of our day in the green room where they gave us wifi, coffee, power, and a flat surface. So Rob and I set up a portable office. The three blowers we brought with us helped decorate the place.
We can's share the full presentation, but we can discuss some key slides. They gave us 10 minutes to talk about our solution, then 10 for questions.
The problem is fairly simple. People designing stacks need custom blower solutions because of the hydrogen and the pressure/flow requirements on the air side of a hydrogen fuel cell.
PADT's proven solution is to design custom blowers to meet very specific needs.
In the end, we just wanted to know that we are excited to see that Hydrogen fuel cells are seeing a resurgence, our blowers are perfect for most applications, and that we would love connections to people who need our solution.
When we were done we went inside the house. Room after room was stunning.
We gave a 2-minute short presentation with this great view behind us.
A great day where we met a lot of great people from around the country. Sadly, PADT didn't win the competition. The truth is that the challenge was for new and disruptive technology and we talked about proven and enabling solutions. Useful to the sponsors, but not what they were looking for when handing out prizes.
Visiting Colorado in the summer is always a nice break for those of us from Phoenix. We hope to participate in this and related events in the future.
If you have any needs for air our hydrogen blowers for your fuel cell, or any complex engineering for your product, please contact us and we would love to learn how we can help.

No product is perfect. Much of engineering is trying to determine when a part will fail in the field or when there are field failures, why it failed and how to fix it. Although simulation and engineering experience can make a huge difference, sometimes the best way to understand product robustness in the real world is through duty cycle testing; designing a test that puts the product through the varied and repeated loading that it will see in use.
This type of testing is perfect for automation. For decades, PADT has been designing testing devices for our customers to determine durability, uncover problems, and verify that proposed solutions work. Over those years our engineers have developed guidelines that we use to design tests and test apparatus. We got together and summarized that experience in the ten suggestions listed below.
But first, it would be good to define what automated product duty cycle testing is.
Automated Product Duty Cycle Testing Defined
When a physical product is used, it sees some sort of loading; force, pressure, temperature, friction, chemicals, sunlight, etc... That loading causes deformation of the various materials used or changes the physical properties of those materials. In most cases, the deformation or property change is not permanent. But sometimes the loads are large enough or are replied long enough to cause permanent changes. Metal fatigues, rubber tubes become brittle, or glue fails.
Large loads are easy to test. You apply them and see what happens. But long term loading, especially a set of repeated loads, needs to be applied over time. This type of long-term testing that applies the loads the product will see over time is called duty cycle testing. Add in the need to apply temperatures cycles, humidity, and power loads - all things that components see in the real world - and the value of automation multiplies.
As engineers, when we see something that happens over time and repeats, we know that automation can be used to reduce cost and enforce repeatability. And that is why most duty cycle testing is automated. But those time savings and that repeatability are only effective if the test and the text fixture are designed correctly, which leads us to PADT's ten suggestions.
1: Define the purpose and the expected outcome of the test
Most people define the purpose or the outcome, but not both. This really starts with understanding who the customer is for the test, even within the same company. What do they need from the test and why do they need it.
2: Map the full duty cycle being tested
The physical behavior of a system, especially over time, is impacted by all of the loads that the system sees. The cause of a failure or performance degradation is often not one load, but some unexpected combination of loads. You may think a problem may be caused by say, a bending load that happens tens-of-thousands of times. But it may be that bending load combined with a torque that only occurs every once in a while.
3: Document the test process, keeping it as simple as possible
Simplicity is the key here. Complexity adds cost, slows schedules, and introduces irrelevant failure modes. Designing is like writing a good story. Put everything down, then start cutting. Keep cutting until you only have exactly what you need.
4: Design the apparatus to the test
This seems obvious, but it can often be missed. The three previous suggestions need to be reviewed before, during, and after the design process. Every feature, chunk of code, or fixture needs to be there for a reason. The device must carry out the test process and apply the full duty cycle while meeting the purpose and expected outcome of the test.
5: Make the system versatile
After developing our second or third test rig, we discovered that our customers almost always wanted to add new loads or change loading. You may design a system to test one component, to find that a different component is failing more in the field so you need to change the test to load that part. If you design the apparatus to allow for easy changes that don't require a complete redesign, you can create a far more valuable device.
6: Make the remaining human steps as easy as possible
The whole point of automation is to take humans out of the loop. But someone still has to load, unload, repair, and maintain the system. With so much focus on automation, it is easy to make the apparatus difficult to use. Human interface design still plays an important role.
7: Keep the hardware as simple as possible
Simplicity is the key to success in most designs, and automating duty cycle testing is no different. The repetitive nature of the operating steps and long run times make it especially important. Also, if you make the design too complex it is more difficult to capture and interpret results.
8: Invest in robust, off-the-shelf industrial quality equipment.
Do not try and save money using hobby or educational hardware or in making your own components, unless what you need is not commercially available. Remember, you are measuring the robustness of your product so having robust equipment to carry out the testing is critical. There is a reason why an industrial controller costs more. Invest in hardware that results in a test system that will last.
9: Spend the time and money upfront to automate as much as possible
Just as you should invest in high-quality hardware, you should put time and money into automating as much as possible. It is tempting to save money by saying "we can have a person do this step" but when you do that you introduce long term costs, delays, and a source of error.
10: Test the test before releasing the apparatus to the customer
Plan for a lot of testing of the system before official testing starts. This can seem obvious but because the focus of the design process is a test itself, it is easy to forget that the hardware and software need to be tested before they are released for use.
Better automated testing is achievable
Testing of your products should never be an afterthought or an add-on to the product's design. Plan for it as an important part of the product lifecycle. If you follow the guidelines above and budget the proper time, money, and space (don't forget you will need a place to do the testing) you can achieve a greater understanding of the robustness, failure modes, and efficiency of the things you make.
If you need help with duty cycle testing, please reach out to PADT. Our expertise in project management, engineering problems solving, controller programming, industry applications, and creative design are a unique combination that results in better fixture design and more useful information from your testing.
We can assist you in the design or take on the whole project, including doing the testing here at our facility. Contact us at email@example.com orand ask to speak to someone in our Engineering Services Team about product testing. And don't forget, we have world-class simulation and 3D Printing here on site to speed up the process and deliver deeper insight.

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.
Posted on September 21, 2017, by: James BarkerOn September 11th and 12th Mario Vargas (Hardware Manager for PADT Inc.) and I (James Barker, Application Engineer for PADT Inc.) attended Convergence 2017 in Los Angeles, CA. This event is held by 3D Systems and is the America’s Software Partner Meeting. Many strategic partners were in attendance from all across the USA, Canada, and Latin America. We were able to learn about some new enhancements to Geomagic that will help you with Inspection or Reverse Engineering BIG time! The first day of meetings we heard from Vyomesh Joshi (CEO of 3D Systems referred to as VJ). He mentioned that 3D Systems has committed 17% to R&D and after going to this event it is apparent! VJ briefly talked about each of their software options. The 1st being Control X and how Polyworks currently has the edge for inspection software but after this next software release, he and other 3D Systems employees seemed confident that they could surpass Polyworks. The 2nd software he talked about was Freeform which allows users to freely design parts by using a haptic device. This software would be great for creating custom shapes on a whim. If you haven’t tried a haptic device, you need to! It will blow your mind as a designer with the freedom you get by using the haptic device and this Freeform Software. The 3rd software he talked about was Cimatron which aids in the design of mold and die design. Of the top 10 largest USA mold makers, 7 of them use Cimatron Software. The 4th software is something new that will be released later this month. I would love to tell you more about it but can’t…. sorry! A little about why Mario and I attended this convention, PADT Inc. offers 3D Scanning as both a service and also as hardware or software you can buy. We use both Geomagic Design X and Geomagic Control X and have experts that are scanning parts for customers for either inspection results or for reverse engineering purposes at our Tempe, AZ office. The scanner that we use is a CMM quality scanner from Zeiss. This scanner is capable of scanning 5 million points per scan! We also offer 3D Systems Capture and Capture Mini scanners which are great tools for reverse engineering. Each time they scan a part they are capturing about 1 million points per scan. I am located in the Salt Lake City, Utah office and have a Capture Mini scanner that anyone wanting to see and demo, can come look at and evaluate at our office. Same holds true for the Capture scanner and Zeiss scanner in our Tempe, AZ Headquarters. Since we offer these services, we love knowing what new tools are available with these product releases. Jumping back to the conference, on September 12th, there were breakout sessions. We chose to go to the Geomagic Design X session to see what enhancements have been made. This software is the preferred software in all of the industry for reverse engineering parts. There were many different vendors/partners in the room we were at. There was even a rep from Faro who prefers to sell Geomagic Design X software with each Faro Arm that he sells because this software is so powerful. The neat thing about this software is all of the improvements that have been made to it. If you are accustomed to designing parts with Solidworks, Solidedge, NX, Catia, Pro-E or any of the other CAD software, you will be able to use this software with ease. Every command that you execute within Design X is editable just like the major CAD software. You have the ability to create sketches on planes or to make life even easier, there are wizards that automatically create sketches and perform a command like an extrusion or revolve that is editable after completing the wizard. After you have finished reverse engineering your parts within Design X, you can live transfer your new CAD data over to the above-mentioned CAD software. Once you have imported this data into NX or Solidworks, you can again edit any of the sketches that were created within Design X but now in your software of choice! I would love to show you how powerful this software is. There is a reason why it is the preferred reverse engineering software in the industry. Geomagic Control X session was next. It also happened to be the last session of the day. To be honest, I have only used Design X so I was looking forward to learning more about this software. From all the demo’s that I have seen in the past from this software, it appeared really hard to use. That is all changing with this new software release and is the reason why VJ is confident that it will compete and could exceed Polyworks as the preferred software for inspection. The biggest thing that stuck out to me was the ability to set up a workflow for scanned data for inspection so that you can create your inspection reports. The idea is that if you have a part that needs to be inspected for quality, you 3D scan the part and then import the CAD file. By overlaying the scanned data over the CAD data you can show the deviation within the 2 parts and you are able to have different views in a 3D PDF to share with others the actual quality of the part. As you are assigning your GD&T to this first inspection file, you are creating the first steps of the workflow. There are many options for the workflow that you can create and 3D Systems has made it easy to create the workflow. I feel that the power of this software is when you can open up the results of the first inspection report and do a split screen on your monitor to show the 100th or 1,000th part side by side and see how that part deviates from the first. I had a great time in California at this event even though all of our time was spent at the hotel. The streets looked nice from the window on the 11th floor. Maybe next time we will venture out! If anyone from 3D Systems is reading this, let’s go out to eat next time instead of eating at the hotel for breakfast, lunch, and dinner! Although the view from the dining room was nice! If you have any questions about 3D scanning whether it is for Inspection or for Reverse Engineering, let us know at PADT Inc. We look forward to helping you.
Aerospace Summit, Additive Manufacturing Peer Group, and Industry-Education Partnership – A Three Event, Three State Hat Trick
Posted on June 23, 2017, by: Eric MillerSometimes everything happens at once. This June 22nd was one of those days. Three key events were scheduled for the same time in three different states and we needed to be at all of them. So everyone stepped up and pulled it off, and hopefully some of you reading this were at one of these fantastic events. Combined they are a great example of PADT's commitment to the local technology ecosystem, showing how we create true win-win partnerships across organizations and geographies. Since the beginning we wanted to be more than just a re-seller or just consultants, and this Thursday was a chance to show our commitment to doing just that.
Albuquerque: New Mexico Technology Council 3D Printing Peer Group KickoffEveryone talks about how they thing we should all work together, but there never seems to be someone who is willing to pull it all together. That is how the additive manufacturing committee in New Mexico was until the New Mexico Technology Council (NMTC) stepped up to host a peer group around 3D Printing. Even though it was a record 103f in Albuquerque, 35 brave 3D Printing enthusiasts ventured out into the heat and joined us at Rio Bravo Brewing to get the ball rolling on creating a cooperative community. We started with an introduction from NMTC, followed by an overview of what we want to achieve with the group. Our goals are:
- Create stronger cooperation between companies, schools, and individuals involved in 3D Printing in New Mexico
- Foster cooperation between organizations to increase the benefits of 3D Printing to New Mexico
- Make a contribution to New Mexico STEM education in the area of 3D Printing
Once that was done PADT's Rey Chu gave a presentation where it went over the most important developments in Additive Manufacturing over the last year or so. He talked about the three new technologies that are making an impact, new materials, and what is happening business wise. Check out his slides to learn more: NMTC-PADT-New-3D-Printing-2017_06_22
After a question and answer period we had some great conversations in small groups, which was the most valuable part. If you want to learn more, please reach out to firstname.lastname@example.org and we will add you to the email list where we will plan and execute future activities. We are also looking for people to be on the steering committee and locations for our next couple of meetings. Share this with as many people as you can in New Mexico so that next event can be even better!
Denver: MSU Advance Manufacturing & Engineering Sciences Building OpeningMeanwhile, in Denver it was raining. In spite of that, supporters of educating the next generation of manufacturers and engineers gathered for the opening of the Advanced Manufacturing and Engineering Sciences Building at Metropolitan State University. This 142,000 sqft multi-disciplinary facility is located in the heart of downtown Denver and will house classes, labs, and local companies. PADT was there to not only celebrate the whole facility, but we were especially excited about the new 3D Printing lab that is being funded by a $1 million gift from Lockheed Martin. A nice new Stratasys Fortus 900 is the centerpiece of the facility. It will be a while before the lab itself is done, so watch for an invite to the grand opening. While we wait we are working with MSU, Lockheed Martin, Stratasys, and others to put a plan together to develop the curriculum for future classes and making sure that the engineers needed for this technology are available for the expected explosion of use of this technology. email@example.com or give us a call. Phoenix: 2017 Aerospace, Aviation, Defense + Manufacturing Conference The 113f high in Phoenix really didn't stop anyone from coming to the AADM conference. This annual event was at ASU SkySong in Phoenix and is sponsored by the AZ Tech Council, AZ Commerce Authority, and RevAZ. PADT was proud to not only be a sponsor, but also have a booth, participate in the advanced manufacturing panel discussion, and do a short partner presentation about what we do for our Aerospace and Defense Customers. PADT-AeroConf-AZTC-2017
We had great conversations at our booth with existing customers, partners, and a few people that were new to us. This is always one of the best events of the summer, and we look forward to next year.

Posted on February 8, 2017, by: Eric MillerDid you know that PADT does scanning of parts? No? You are not alone. We recently ran into several customers who were sending their scanning out of state and didn't know that they could have it done by PADT, someone who is already a trusted partner. So we thought it would be a good time to do an update on our Scanning services and provide some additional background on what it is.
Part Scanning 101The idea behind part scanning is that you want to take a part in the real world, and get an accurate model in a computer. To do this you somehow measure the part with a computer, getting a three dimensional representation of the parts surface. Today, there are six basic ways to do this:
PADT offers Structured Light and Cross Sectional ScanningAll of these methods create points in space. The more sophisticated the software, the more automatic the process of assembling the points to define the surfaces of the full object. These points are sometimes called a "point cloud." The Point cloud can them be turned in to a faceted representation of the object. For many people, this is all they need. This faceted representation can be rendered on a computer screen or 3D Printed. It can also be used with inspection software to determine the accuracy of the part relative to its original specification as well as variations across multiple copies of the same geometry. If users need more, like a full CAD model, that can be created from the point cloud using specialized software. PADT uses Geomagic DesignX. This tool not only creates usable geometry, but it can export in the customer's native CAD format. To do accurate part scanning you need:
- A precision scanning device
- Software to take the measured data and create an accurate point cloud. This includes repair and cleanup tools.
- Software to convert the point cloud into a usable 3D CAD model
- or, Software to conduct accurate inspection on the measured geometry.
Why does Part Scanning Take so Long and Cost So Much?When people ask for their first part scanning quote, they can often be surprised by the cost. The scanning process doesn't look that hard. And to be honest, the amount of time you actually spend scanning most parts is pretty short. The time is spent on the preparation, scanning hard-to-reach areas, the clean up, and then converting the data in to usable formats. If we are working with a light based scanner, we have to prepare the parts so that they reflect the light properly. Sometimes we have to cover the part with a find powder, sometimes we may even have to paint it. What we need is for the reflection and color of the part to not interfere with the scanning. If we are using cross sectional scanning, the part needs to be cast inside a rigid material, so the part we are scanning does not distort as we remove layers. In addition, if the part is not a solid light or dark color, it may need to be died to provide contrast for the camera. Both processes also require some study to determine the orientation of the part relative to the scanner and how the scanning process will take place. Once all this is worked out, the scanning often goes very fast. If there are nasty little parts that are hard to get to or that confuse the device, the engineer may have to modify things, do some special localized scanning, or even make castings that are then scanned. As is usual with technical processes, a very small portion of the surface being scanned may take up the vast majority of the scanning time. Once the scanning is done, the real hard work begins. Although software is much better than it was in the past, the resulting point cloud needs to be massaged and cleaned. Stray data is removed, and points from different scans need to be positioned and combined. Then everything must be checked. If a CAD solid model is needed, then the engineer must spend considerable time dealing with complex features and transition areas. As with the scanning, the bulk of the time spent creating a CAD model is spent on a relatively small percentage of the geometry. All of this adds up. Plus, to be honest, things rarely go as planned and unexpected issues arise that need to be dealt with.
Part Scanning Services at PADTNow we get to the important part of this post: hiring PADT to do your scanning. We added this capability to support our 3D Printing customers that wanted copies of physical parts. But as we looked at it, we found that we also had customers who needed inspection and reverse engineering of legacy parts. We studied the problem for some time and found the right tools and people to make it happen. Our primary scanner is a Zeiss Comet L3D 5M STructured light scanner. It used to be called a Steinbichler, till Zeiss bought them in 2015. Although it is portable and easy to manipulate, the Comet L3D 5M is highly accurate. It allows us to scan everything from small medical devices to the front end of acar, and to know that the resulting geometry will be accurate and usable. This is the best option for inspection and reverse engineering of high-precision parts. We also have a Geomagic Capture scanner. Although less accurate it is more portable and simpler to operate. It is ideal or taking to a customer and getting geometry for reverse engineering or part copying. If parts have internal features, and are made of plastic, we use our Cross Sectional Scanners. These high precision devices do a fantastic job and are really the best way to capture inside surfaces. Our customers love it to see how injection molded parts are coming out on well used molds. If anything else is needed, our experts can outsource to a niche supplier.
Want to do it Yourself?If you need to do your own scanning, no worries. PADT also sells all the tools we use inhouse to customers that need the capability internally.

Posted on January 31, 2017, by: Eric MillerCutting corners rarely pays off, and that is especially true in product development when you skimp on physical or virtual prototyping. In "Why accurate prototypes are important to product development success" I take a look at why accurate prototyping is so important, with some real world lesson learned as examples.

Posted on October 19, 2016, by: Eric MillerThe teams are set, the judges have confirmed. Details on the fake company has been shared. It is time to see how the professionals pitch a tech startup. The area's best startup incubators and accelerators are facing off in this head to head competition to take home the awesome Unicorn Cup and bragging rights. The teams are:
Thomas Schumann and Patti DuBois from CEI Nate Mortenson from Tallwave Wiley Larson from ASU Lauren McDannel and John Johnson from Seed SpotOur distinguished panel of judges consists of
Rebel Brown of Cognoscenti Carine Dieudé of Altima Business Solutions Jim Goulka of ATI Christie Kerner of ASU David McCaleb of ATIPerfect Pitch is a contest where teams present the same fictitious technology startup company. A group of expert judges will determine who gave the best pitch. The event is part of PADT's Nerdtoberfest celebration of engineering and manufacturing in Arizona, and takes place from 4:30-6:00 on Thursday, October 27th at our Tempe offices. Everyone is invited! We will have an overflow area set up if we get more than can fit in our seminar room where you can watch live. We will also be streaming the event live to the world (watch this blog and social media for the link). If seeing the best of the best pitch is not enough, here is some info about our fictitious Company: barqk! At barqk!, we deploy the latest cloud based machine learning and big data algorithms to convert your dog’s barking into words on your mobile device so that you can understand your pet’s needs, if they are sick, and be made aware of danger. Dog owners face significant problems communicating with their pets. Although you can train a dog to obey commands, the dog cannot tell it’s owners what it needs or wants. This leads to significant stress for the owner and may lead to death when the animal cannot communicate an obvious and present danger. Barqk! has created a cloud connected wearable device for dogs that records their barking and uses machine learning and big data algorithms to convert dog-speak into human-speak. The translated words are sent via text or through our app to the owner’s phone. Initially the owners provide feedback to the network, and the responses of all owners to every dog’s bark are collected as big data then fed through our proprietary algorithms that use Bessel functions and advanced machine learning approximations to develop a consensus on what a given bark means. Over time a translation for each dog will be developed and we expect 87% accuracy.
