Press Release: ZEISS Industrial Metrology Signs PADT as an Authorized Distributor of its COMET® Series of Blue Light 3D Optical Scanners

Scanning is one of the fastest growing parts of PADT’s business, and with the announcement of a new agreement to distribute for ZEISS Industrial Metrology, we are growing even faster.  Blue Light 3D Optical Scanners are amazing devices that allow users to create accurate surface maps of almost any geometry.  We have been using this technology in-house for our scanner services for some time, now we wanted to also make them available to our customers.

You may remember when PADT announced that we had partnered with Steinbichler to provide 3D optical scanners.  Well, we are not dumping Steinbichler.  Their technology was acquired by ZEISS Industrial Metrology.  We have been waiting for the acquisition to finish up and for the Steinbichler team to be fully integrated before we signed up to represent these fantastic devices again.  That happened and we are back selling them in Arizona, Colorado, New Mexico, and Utah.

What we like about these optical devices are the incredibly accurate lenses, from ZEISS, and the large and accurate CCD chips.  This combination gives fantastic quality.  In addition, we can swap out different lenses for specific applications and the software that comes with the system is outstanding.  After beating our device to death last year on services work, we feel very comfortable recommending it to all of our customers.

Here is a video on the primary product we are selling, the ZEISS L3D 2:

And that is also the advantage of buying your optical scanning solution from PADT. We use this stuff every day on a variety of applications. So we understand our needs, and we know how to get the most out of the hardware and software. So when you are making your decision on what to buy, and when you need support once you have made your investment, you know PADT is the best option to help you out.

ZEISS Industrial Metrology Signs PADT as an Authorized Distributor of its COMET® Series of Blue Light 3D Optical Scanners

PADT Customers Seeking to Bring Precise Inspection Services or Reverse Engineering In-house Now Have World-class Equipment at Their Fingertips

TEMPE, Ariz., February 27, 2018 Phoenix Analysis and Design Technologies (PADT), the Southwest’s largest provider of simulation, product development, and 3D Printing services and products, today announced it has signed an agreement with ZEISS Industrial Metrology to become an authorized distributor of the COMET Series ®  product line of Blue Light Optical Scanners. ZEISS Industrial Metrology is a business group of ZEISS and is a worldwide leading supplier of optical and contact measuring technology.

“When we made the strategic decision to add scanning devices to our distribution portfolio, we evaluated all of the leading structured light 3D optical scanning systems,” said Rey Chu, co-owner and principal, PADT. “The ZEISS COMET clearly emerged as our preferred choice. Not only did it serve as a workhorse, results were more efficient and accurate and we could scan a wider variety of objects. The ZEISS COMET is the obvious choice for our customers who want to bring inspection or reverse engineering services in-house.”

Scanners in the COMET Series utilize the latest blue light technology to capture 3D data accurately and fast. The system operates by projecting patterned light, also called structured light, onto an object and the camera captures the image. The Colin3D software processes the image and creates a 3D “point cloud” with millions of points. The software further processes point cloud data for downstream applications – reverse engineering, inspection and rapid prototyping to name a few. The portable COMET series has two models – COMET 6 and COMET LƎD 2.

“PADT was selected as an authorized distributor of our COMET Series because of its depth and breadth of knowledge of engineering services and 3D scanning technology,” said John Grzybowski, business sales manager at ZEISS Industrial Metrology. “They serve as an excellent partner and a valued ambassador of the ZEISS brand.”

Helpful New Meshing Feature in ANSYS Mechanical 17.0 – Nonlinear Mechanical Shape Checking

ansys=new-mesh-r17Meshing for Nonlinear Structural Problems

Overcoming convergence difficulties in nonlinear structural problems can be a challenge. I’ve written a couple of times previously about tools that can help us overcome those difficulties:

I’m pleased to announce a new tool in the ANSYS Mechanical tool belt in version 17.0.
With version 17.0 of ANSYS we get a new meshing option for structural simulations: Nonlinear Mechanical Shape Checking. This option has been added to the previously available Standard Mechanical Shape Checking and Aggressive Mechanical Shape Checking. For a nonlinear solution in which elements can become significantly distorted, if we start with better-shaped elements they can undergo larger deformations without encountering errors in element formulation we may encounter fewer difficulties as the nodes deflect and the elements become distorted. The nonlinear mechanical setting is more restrictive on the element shapes than the other two settings.

We’ve been recommending the aggressive mechanical setting for nonlinear solutions for quite a while. The new nonlinear mechanical setting is looking even better. Anecdotally, I have one highly nonlinear customer model that reached 95% of the applied load before a convergence failure in version 16.2. That was with the aggressive mechanical shape checking. With 17.0, it reached 99% simply by remeshing with the same aggressive setting and solving. That tells you that work has been going on under the hood with the ANSYS meshing and nonlinear technology. By switching to the new nonlinear mechanical shape checking and solving again, the solution now converges for the full 100% of the applied load.
Here are some statistics using just one measure of the ‘goodness’ of our mesh, element quality. You can read about the definition of element quality in the ANSYS Help, but in summary better shaped elements have a quality value close to 1.0, while poorly shaped elements have a value closer to zero. The following stats are for tetrahedral meshes of a simple turbomachinery blade/rotor sector model (this is not a real part, just something made up) comparing two of the options for element shape checking. The table shows that the new nonlinear mechanical setting produces significantly fewer elements with a quality value of 0.5 or less. Keep in mind this is just one way to look at element quality – other methods or a different cutoff might put things in a somewhat different perspective. However, we can conclude that the Nonlinear Mechanical setting is giving us fewer ‘lower quality’ elements in this case.

Shape Checking Setting Total Elements Elements w/Quality <0.5 % of elements w/Quality <0.5
Aggressive Mechanical 31683 1831 5.8
Nonlinear Mechanical 31865 1249 3.9

Here are images of a portion of the two meshes mentioned above. This is the mesh with the Aggressive Mechanical Shape Checking option set:ansys-new-meshing-17-01
The eyeball test on these two meshes confirms fewer elements at the lower quality contour levels.

And this is the mesh with the Nonlinear Mechanical Shape Checking option set:

ansys-new-meshing-17-02

So, if you are running nonlinear structural models, we urge you to test out the new Nonlinear Mechanical mesh setting. Since it is more restrictive on element shapes, you may see longer meshing times or encounter some difficulties in meshing complex geometry. You may see a benefit in easier to converge nonlinear solutions, however. Give it a try!

Getting to Know PADT Medical: An Interview with Skott Skeleton

clip_image001

PADT Medical has been an established group within Phoenix Analysis & Design Technologies (PADT) for a while now. Over the years it has grown and we have added new employees with new skills and experience. But one “employee” has been a member of the team since the beginning, providing guidance and setting a strong example on a variety of medical device product development projects. Skott Skeleton may not be physically substantial, but his skills are rock solid. If you have been fortunate enough to have toured PADT, you have probably met Skott as he hangs around in the PADT Medical office area.

As we launch this new blog based format for sharing information and news with people interested in what is going on with PADT Medical, we thought it would be a good opportunity to sit down and ask Skott a few questions and learn more.

EM: Skott, why don’t you share with our readers why you decided to join PADT Medical?

SS: I didn’t decide anything. One day I was hanging around with my buddies in a warehouse in China, and someone comes along, shoves me in a box and ships me off to the desert. But once I got here, I really fell in love with the place. PADT is a great company. Everyone here is smart, they have good senses of humor, and they do not judge me because of my body type.

EM: What is your roll within PADT Medical?

SK: Mostly I just watch. I move around in the office and I watch. Everyone knows that I’m there and that I am watching. Another important role that I play is to remind everyone why they are doing what they are doing what they are doing. For many engineers, parts are parts. But PADT Medical works on parts that are used to heal and repair people. There is nothing like a person stripped down to the basics to remind everyone that we are working on devices that can really make a difference in people’s lives. And, if we do it right, a good difference.

EM: PADT has been doing product development for over 15 years, including many Medical Devices, why create a special group and brand it apart from PADT?

SS: After doing a couple of medical projects two things become clear. First, the development process for medical devices is different because of the quality requirements, the material issues, the regulatory environment, and the difficulties in designing things that go inside of or interact with human bodies. Second, medical device customers know that they need specialists. PADT Medical customers know that generalists might be able to do some things very well, but that engineers in this space really need to know what is required for medical devices. So we formed a group dedicated to nothing but medical device product development. And to convey that specialization and focus to people inside and outside of the company, we created the PADT Medical brand.

EM: There are a lot of people out there doing medical device product development, what sets PADT Medical apart?

SS: I’d say their engineering skills and their ability to simply get stuff done. When I’m standing in the corner and no one remembers I’m there, I hear customers talk. The main thing they say over and over again is how impressed they are with the breadth and depth of engineering knowledge within PADT Medical. The other thing they say is that when the PADT Medical team signs on to a task, they get it done. They get it done efficiently and with a minimal amount of delay and floundering, especially with difficult tasks.

I also think there are a few other things that set PADT apart but I could go on and on about it, or you can read the PADT Medical part of the website. Let me list the most important bits:

  • Access to world class FEA and CFD simulation, right here at PADT
  • In house rapid prototyping, injection molding, and machining
  • A flexible and robust product development process
  • Established and proven processes

That is just the tip of the iceberg.

EM: That is very impressive. PADT Medical really seems to have a lot of unique skills, experience and tools. But no group can do everything themselves, what do you do when you can’t do what you need in house?

SS: Ah yes, our vendors. We love our vendors. We have over 350 vendors and 65 are approved for medical device work. You are exactly right when you say that we can’t do everything ourselves. So we have spent a lot of time finding and qualifying lots of different vendors. We use our quality system to make sure they can deliver what our customers need, exactly the way they need it. Then we continually work with them to make things better and more affordable.

I should also add that not the way a lot of companies do it this way. We don’t have a purchasing department that beats up our vendors on price and schedule. Our engineers and technicians work directly with our vendor network as partners to come up with a reasonable win-win-win solution for everyone. We want our customers to win, we want PADT to win, and we want our vendors to win.

EM: I’ve heard that PADT Medical is well known as a team that works very closely with vendors and customers. How close?

SS: So close that sometimes I get wheeled out of my comfortable corner to make room for our customers and vendors to actually move into our space here. Only a few partners end up collocating, but even if they are visiting for a day or a few weeks, we make room, and we work side by side till the project is complete.

EM: Skott, we are running out of time and you probably need to get back to the PADT Medical room. But before you go, is there anything else you would like to share with our readers about PADT Medical?

SS: Wow. That is a tough one. There are so many things that we do here, so many success stories. So many difficult challenges that we have identified and overcome.

When I think about it, I guess the only thing I can say is that if anyone out there is thinking of using PADT Medical for their medical device development project, you should meet with us to really understand all we have to offer. Some of it can be put down on paper or explained in a PowerPoint, but much of the value that PADT Medical adds is intangible. Things like experience, problem solving, perceptiveness, mechanical intuitiveness, and organizational skills. If you want to learn more, let us do a proposal for you, or better yet, let us work on a small project where we can show you first hand.

EM: Well thank you very much Skott. It has been a bit creepy talking with you, but it has been informative. I hope we can do this again soon.

SS: Anytime. I am looking forward to the new blog. I hope to meet some of the readers when they come in for a tour.

[Editors Note: Yes, we know this is a silly way to do an article about what sets PADT Medical apart, but let’s be honest – if I had written an interview with one of the mangers here you would not read it. This way we can have some fun and you might learn a thing or two about what sets PADT Medical apart.  Or you will at least get to roll your eyes a few times.  Share your thoughts in the comments below. – EM]
