Manufacturing is about to go through a major revolution, one that will have impact around the world. A new generation of automation will be changing the way things are made. In “The next revolution in manufacturing is full automation” I take a look at what it all means.
Some of you have probably already noticed, but ANSYS Mechanical licenses have some changes at version 17. First, the license that for years has been known as ANSYS Mechanical is now known as ANSYS Mechanical Enterprise. Further, ANSYS, Inc. has enabled significantly more functionality with this license at version 17 than was available in prior versions. Note that the license task in the ANSYS license files, ‘ansys’ has not changed.
|16.2 and Older (task)||17.0 (task)|
|ANSYS Mechanical (ansys)||ANSYS Mechanical Enterprise (ansys)|
The 17.0 ANSYS License Manager unlocks additional capability with this license, in addition to the existing Mechanical structural/thermal abilities. Previously, each of these tools used to be an additional cost. The change includes other “Mechanical-” licenses: e.g. Mech-EMAG, Mech CFD. The new tools enabled with ANSYS Mechanical Enterprise licenses at version 17.0 are:
|Fatigue Module||Rigid Body Dynamics||Explicit STR||Composite PrepPost (ACP)|
|SpaceClaim||DesignXplorer||ANSYS Customization Suite||AQWA|
Additionally, at version 17.1 these tools are included as well:
These changes do not apply to the lower level licenses, such as ANSYS Structural and Professional. In fact, these licenses are moving to ‘legacy’ mode at version 17. Two newer products now slot below Mechanical Enterprise. These newer products are ANSYS Mechanical Premium and ANSYS Mechanical Pro. We won’t explain those products here, but your local ANSYS provider can give you more information on these two if needed.
Getting back to the additional capabilities with Mechanical Enterprise, these become available once the ANSYS 17.0 and/or the ANSYS 17.1 license manager is installed. This assumes you have a license file that is current on TECS (enhancements and support). Also, a new license task is needed to enable Simplorer Entry.
Ignoring Simplorer Entry for the moment, once the 17.0/17.1 license manager is installed, the single Mechanical Enterprise license task (ansys) now enables several different tools. Note that:
- Multiple tool windows can be open at once
- g. ANSYS Mechanical and SpaceClaim
- Only one can be “active” at a time
- If solving, can’t edit geometry in SpaceClaim
- Capabilities are then available in older versions, where applicable, once the 17.0/17.1 license manager is installed

Everyone needs a vacation. After over 15 years of service our Sinterstation 2500Plus needed some facility upgrades and machine updates. That work is now done and our SLS system is back up and running and better than ever, producing parts for customers who have come to count on its unique capabilities.
Selective Laser Sintering (SLS) is a process that uses a high power laser to fuse a bed of powdered material together, sintering the loose powder into solid geometry. It is one of the more mature and robust 3D Printing processes available and is especially well suited for making large strong parts.
We currently run Nylon 11 and Glass Filled Nylon 12 in our machine which has a build volume of 13″ x 11″ x 16.5″ and a layer thickness of 0.004″
Few service providers have as much experience as PADT with this system, we have been using it for over 15 years. During that time we have upgraded almost every component and during the recent downtime, the system was fully calibrated and tuned for maximum precision and performance. We are also experts on how to post process the parts that come out of this machine, including painting and other coatings.
Just a Part of 3D Printing at PADT
PADT features 3D Printing services using Stratasys FDM and PolyJet technologies, making precision parts with a wide variety of materials and colors. We also offer Stereolithography (SLA) Additive Manufacturing services along with soft tooling and injection molding consulting.
If you are using a big impersonal 3D Printing “mill” or are not sure where to get your 3D Printing done, reach out to PADT. We have been doing it since 1994 and have hundreds of happy and loyal customers.

The year is almost halfway over and the pace of events that PADT is attending and holding is slackening a bit as we account for summer vacation and, in Phoenix, the blistering heat. Take a look below to see what we have planned, mostly webinars, and review what happened in a fun filled May below.
June 20: Utah Technology Council
“Future of Technology in Utah “
PADT’s Anthony Wagner and James Barker will be attending this outstanding event featuring key members of the Utah technology community and the Governor or Utah, Gary Herbert.
June 28: Jefferson County Aerospace & Defense Small Business Industry Day
PADT’s Norman Stucker and James Barker will be manning a booth at this gathering of small but active Aerospace companies in the area to talk learn how everyone can contribute to Colorado’s dynamic Aerospace industry sector.
Join David Mastel the IT Manager/Chief HPC Architect for PADT, Inc. and ANSYS users in the Twin Cities area for an ANSYS user meeting including technical presentation with handouts.
We have several great Webinars on tap for June. All PADT webinars are recorded, so even if you can’t make the specified time register and we will send you a link to the recording.

May Events in Review
We attended a lot of events in May where we learned a ton, and continued to grow our network.
Patrick Barnett and Eric Miller ventured out to the heart of the Silicon Valley to attend Internet of Things World 2016. We learned a ton and met a couple of potential suppliers. Learn more about what we learned on our IoT page: www.padtinc.com/iot
The big, huge, important event for the month was RAPID in Orlando, FL. PADT’s Rey Chu and Dhruv Bhate attended, and Dhruv presented. The highlight of the show was seeing all the new products that were introduced, especially from Stratasys. We were also able to catch up with old friends and make some new ones.
The most informative event of the month was the National SBIR/STTR Conference. PADT’s Rob Rowan flew to our nation’s capital and was able to meet with many of the people who are in charge of the SBIR projects we are bidding on. Rob felt that the best part was getting to better know what our customers are really looking for.
As a parent I know that crayon management has always been a problem in our family, especially when we travel. We could have used the ReadyXO – a simple container that cleverly uses the lid to provide stability so it doesn’t tip over. Now is your chance to control your crayons and help fund a great entrepreneur, and PADT customer, through KickStarter.
This is a great idea, a simple solution, by an individual entrepreneur who applied good problem solving and engineering to develop a solution to something that most of us have dealt with when we were kids or as parents.
Check out the details at:
Scroll down and read “The Story.” If you didn’t want to get one out of simple necessity, when you hear about the inventor’s journey you will want to back this enterprise immediately.
One of the best parts of working at PADT is helping our customers make their ideas work. From a new valve actuator on the International Space Station to clever gadgets. Sometimes we see some great ideas from individual inventors that solve a day-to-day problem with a simple and elegant solution and get to help out just a little on their journey. This is a fantastic example of that.
Help us help them by pre-ordering your ReadyXO Crayon Box on KickStarter and spread the word through social media.
I don’t rant so publicly often, but this new trend to push very long payment terms on to small businesses is just bad for everyone involved. Join the fight! Read the blog posting, “A call for revolution: time to push back on long payment terms” and rise up!
This week’s TECHFLASH blog post in the Phoenix Business Journal takes a look at what companies can do to maximize the software investments they have already made. “Businesses should not worry about the software they need and use what they have” I offer up some best practices for maximizing your company’s software investment.
The May/June 2016 of AZ Business Magazine focuses on innovation and technology business in Arizona. This includes our contribution to the discussion “Large tech companies are critical to a startup community.” In this article I make a case for remembering the big guys out there that train, spawn, fund, and even buy the startups that are out there.
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.
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.

- Sensors and controls: Making a product smart enough for the Internet of Things
- Connectivity: What makes the Internet of Things a big deal
- How to deal with all that data from your Internet of Things device
- Security: This is the biggest challenge for the Internet of Things
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.
We highly recommend this white paper, “Engineering the Internet of Things”
We also have a recording of a very popular webinar that we did: “Engineering the Internet of Things Devices with ANSYS Simulation”
and this video on how ANSYS can drive your IoT Design:
For detailed examples, check out the ANSYS IoT Landing page to get a feel for why so many companies are driving their design with ANSYS simulation software: www.ansys.com/iot
Talking is the Best Approach
We hope that you find all of the material above, and the information we will provide in the coming months useful. But they are no substitute for giving us a call or sending us an email and setting up a face-to-face to talk about your IoT strategy and device development needs. If you are doing the work in-house, we have the hardware and software tools you need to be successful. If you need outside help, you won’t find engineers with more applicable experience.
Give us a call at 1-800-293-PADT or email firstname.lastname@example.org.
This is our final post in a series on The Internet of Things, or IoT. In “This is the biggest challenge for the Internet of Things” I take a look at the monster that keeps IoT companies up at night – Security. In the end, security is a big concern when designing your IoT device, but one that can be easily addressed with the right experts, systems, and planning.
Ken Morgan and Mark Asher of Money Radio interviewed PADT’s Eric Miller to learn more about what we do here and how “We Make Innovation Work” as part of the Business Leader Spotlight.
Listen to the interview here:
PADT’s Ward Rand and Eric Miller were interviewed recently by Chris Gilfallan of “The Record Reporter” about what PADT does and how it impacts the local product development and intellectual property community. It ended up being a great overview and is aimed at helping the Arizona legal profession understand a bit more about what we do. If you have a subscription you can read the article here.
The next step in our look at the Internet of Things, or IoT, is what to do with all that data. Having sensors track something is great, but it makes a lot of ones and zeros. Saying “it is Big Data” doesn’t solve the problem. “How to deal with all that data from your Internet of Things device” I take a look at how planning and using the right tools can give you a handle for this critical part of IoT products.
For several years now PADT has 3D Printed special thank you awards for the fantastic companies that sponsor the Arizona SciTech Festival. This year we decided to stick with the color of the Stratasys Connex3 but add some moving parts. This gear design spins around and was made as one part, we just wash the support material out of the gaps between parts.
This is a great example of going directly from a CAD model to a custom part. Each award has the recipient’s name printed on the smaller gear. Everything was designed in an hour or so and it took about another hour to add in the 30 or so names. We think these may be the best awards we have made so far.
Here is a video showing off how they spin:
Awards are kind of simple and fun. But the same technology is applied by PADT to help our customers design and build better medical devices, rockets, aircraft engines, computers, and pretty much any physical product you can think of. Give us a call at 1-800-293-PADT or email email@example.com to see how “We Make Innovation Work”
While much has been (justifiably) written about HP and XJet releasing new, potentially game-changing products at RAPID 2016, I wanted to write this post about some of the smaller, unexpected joys that I discovered. If I sound overly enthusiastic about the people and companies behind them, it is likely due to the fact that I wrote this on the flight back, staring out at the clouds and reflecting on what had been a wonderful trip: I own no locks, stocks or barrels in any of these companies.
1. Essentium Materials – Carbon Nanotubes and Microwaves to improve FDM mechanical properties
Over the past year, I have studied, written and made presentations about the challenges of developing models for describing Fused Deposition Modeling (FDM) given their complex and part-specific meso-structure. And while I worked on developing analytical and numerical techniques for extracting the best performance from parts in the presence of significant anisotropy, the team at Essentium has developed a process to coat FDM filaments with Carbon nanotubes and extrude them in the presence of microwave radiation. In the limited data they showed for test specimens constructed of unidirectional tool-paths, they demonstrated significant reduction in anisotropy and increase in strength for PLA. What I liked most about their work is how they are developing this solution on a foundation of understanding the contributions of both the meso-structure and inter-filament strength to overall part performance. Essentium was awarded the “RAPID Innovations award”, first among the 27 exhibitors that competed and are, in my opinion, addressing an important problem that is holding back greater expansion of FDM as a process in the production space.
2. Hyrel 3D – Maker meets Researcher meets The-Kid-in-All-of-Us
I only heard of Hyrel 3D a few days prior to RAPID, but neglected to verify if they were exhibiting at RAPID and was pleasantly surprised to see them there. Consider the options this 3D printer has that you would be hard pressed to find in several 3D printers combined: variable extrusion head temperatures (room temp to 450 C), sterile head options for biological materials, a 6W laser (yes, a laser), spindle tools, quad head dispensing with individual flow control and UV crosslinking options. Read that again slowly. This is true multiple degree-of-freedom material manipulation. What makes their products even more compelling is the direct involvement of the team and the community they are building up over time, particularly in academia, across the world, and the passion with which they engage their technology and its users.
3. Technic-Print: New Chemistry for Improved FDM Support Removal
If you manufacture FDM parts with soluble supports, keep reading. A chemist at Technic Inc. has developed a new solution that is claimed to be 400% faster than the current Sodium-Hydroxide solution we use to dissolve parts. Additionally, the solution is cited as being cleaner on the tank, leaving no residue, has a color indicator that changes the solution’s color from blue to clear. And finally, through an additional agent, the dissolved support material can be reclaimed as a clump and removed from the solution, leaving behind a solution that has a pH less than 9. Since PADT manufactures one of the most popular machines that are used to dissolve these supports that unbeknown to us, were used in the testing and development of the new solution, we had an enriching conversation with the lead chemist behind the solution. I was left wondering about the fundamental chemistry behind color changing, dissolution rates for supports and the reclaiming of support – and how these different features were optimized together to develop a usable end-solution.
4. Project Pan: Computationally Efficient Metal Powder Bed Fusion Simulation
I presented a literature review at AMUG (another Additive Manufacturing conference) last month, on the simulation of the laser-based powder bed fusion. At the time, I thought I had captured all the key players between the work being done at Lawrence Livermore National Labs by Wayne King’s group, the work of Brent Stucker at 3DSIM and the many academics using mostly commercially available software (mostly ANSYS) to simulate this problem. I learned at RAPID that I had neglected to include a company called “Project Pan” in my review. This team emerged from Prof. Pan Michaleris’s academic work. In 2012, he started a company that was acquired by Autodesk two months ago. In a series of 3 presentations at RAPID, Pan’s team demonstrated their simulation techniques (at a very high level) along with experimental validation work they had done with GE, Honeywell and others through America Makes and other efforts. What was most impressive about their work was both the speed of their computations and the fact that this team actually had complex part experimental validations to back up their simulation work. What most users of the powder bed fusion need is information on temperatures, stresses and distortion – and within time frames of a few hours ideally. It seems to me that Pan and his team took an approach that delivers exactly that information and little else using different numerical methods listed on their site (novel Hex8 elements, an element activation method and intelligent mesh refinement) that were likely developed by Pan over the years in his academic career and found the perfect application, first in welding simulation and then in the powder bed fusion process. With the recent Autodesk acquisition, it will be interesting to see how this rolls out commercially. Details of some of the numerical techniques used in the code can be found at their website, along with a list of related publications.
5. FDA Participation: Regulating through education and partnership
On a different note from the above, I was pleasantly surprised by the presence of the FDA, represented by Matthew Di Prima, PhD. He taught part of a workshop I attended on the first day, took the time to talk to everyone who had an interest and also gave a talk of his own in the conference sessions, describing the details of the recently released draft guidance from the FDA on 3D printing in medical applications. It was good to connect the regulatory agency to a person who clearly has the passion, knowledge, intelligence and commitment to make a difference in the Additive Manufacturing medical community. Yes, the barriers to entry in this space are high (ISO certifications, QSR systems, 510(k) & Pre-Market Approvals) but it seems clear that the FDA, at least as represented by Dr. Di Prima, are doing their best to be a transparent and willing partner.
What really makes a trip to a conference like RAPID worth it are the new ideas, connections and possibilities you come away with that you may not stumble upon during your day job – and on that account, RAPID 2016 did not disappoint. As a line in one of my favorite song’s goes:
“We’ll never know, unless we grow.
There’s too much world outside the door.”
– Fran Healy (Travis, “Turn”).
