My View: Self-driving car death a sad reminder of the importance of regulation

When someone loses their life, it is too late to start regulating a company’s behavior. The recent tragic death of a pedestrian in a collision with an Uber self-driving car showed that “Self-driving car death a sad reminder of the importance of regulation.

Since the feature is called, “My View” I shared my views on this topic in the Phoenix Business Journal. A little more editorial than my normal business/technology posts in the PBJ.

Forbes.com: Finding True Innovators Is Tough, But The Talent Pool Is There

We have learned the hard way that “Finding True Innovators Is Tough, But the Talent Pool Is There.” And that pool is in the much-maligned millennial generation. In this contributions to Forbes.com, in their Grad of LifeVoice section, I explore what we have learned about that pool and offer up four suggestions:
1. Look for proactive behavior
2. Seek and encourage diversity in your workforce
3. Ask for a creative leam, then encourage more
4. Reward people who challenge your thinking and make you uncomfortable

Phoenix Business Journal: Part 2 of Blockchain and Burning Bridges

Here are the two latest guest blogs in the Phoenix Business Journal:

Beyond the hype, understanding blockchain: Part 2

The latest tech trendiness is a technology for keeping track of transactions called Blockchain. Its popularity stems from the fact that it has some significant advantages over traditional ways of recording transaction.  It is also popular because people have made millions out of thin air using it to track the creation of cryptocurrency. “Beyond the hype, understanding blockchain – Part 2” looks at the downside of Blockchain.

Burning bridges with people in business is just stupid

As tempting as it is, “Burning bridges with people in business is just stupid.”In this guest blog I talk about my own experience of how keeping relationships you wanted to cut has paid off for our business.

Extracting Relative Displacements in ANSYS Mechanical

A recurring theme in ANSYS Technical Support queries involves the separation of rigid-body from material deformations without performing an additional analysis. Many users simply assume this capability should exist as a simple post-processing query(or that in any case, this shouldn’t be a difficult operation). “Rigid-Body” displacements implies a transient dynamic analysis (as such displacements should not occur in static analyses), but as we’ll see, there are contexts within static structural environments where this concept DOES play an important engineering role. In static structural contexts, such rigid-body motion implies motion transmitted across multiple-bodies. There are two important and loosely related contexts we’ll look at; zero strain rotations of the CG and those rotations combined with strain-based displacement.

The following presentation explains the issues including the math behind it, offers solutions including useful APDL marcros, and then gives examples.

Getting to Know PADT: Stratasys 3D Printer Sales and Support

 This post is the eleventh 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 info@padtinc.com or give us a call at 1-800-293-PADT.

When it comes to delivering accurate, robust, and feature-rich additive manufacturing, commonly called 3D Printing, to professional users, one brand of systems stands above all the rest: Stratasys. For over a decade PADT has been a reseller of these outstanding machines in the four-corners states of Arizona, Colorado, New Mexico, and Utah. In fact, our leadership position in the Additive Manufacturing space is built on the foundation of our sales and support history with Stratasys.

Stratasys, The World Leader in Additive Manufacturing

There is one simple reason why Stratasys is the world leader in Additive Manufacturing systems and why so many of our customers keep buying Stratasys systems: They Work.  The whole point of 3D Printing is that you can go from a computer model to a real part as quickly and easily as possible. Stratasys has created a complete set of hardware, material, and software to make that happen.  For hardware, they offer two additive manufacturing technologies: FDM and PolyJet.

FDM, or Fused Deposition Modeling, is the most common technology because it is reliable, accurate and builds strong parts.  FDM was invented by Stratasys over 25 years ago and still forms the foundation of their product line.  It is a layered deposition process that melts a variety of plastics that are then extruded through a nozzle to draw the shape of each layer. From the desktop MakerBot machines to the industry favorite FORTUS 900, there is a machine that works for every need.  Recently, we have been selling a large number of F370’s to new an existing customers.  FMD systems come in a variety of sizes, speeds, costs, and most importantly, material options.  And best of all, the majority of FDM systems come with Stratasys’ patented soluble support material that makes support removal as easy as dropping your part into a cleaning system (many of which are made by PADT).

If you need greater refinement, the ability to change material, or color, then PolyJet technology is your ideal solution.  The power of PolyJet is that it uses inkjet print heads to deposit tiny dots of liquid material on a build layr. That material is then hardened with an ultraviolet lamp. What is cool is that you can have multiple inkjet print heads and therefore deposit a mix of material within a given layer. This allows you to make parts with very hard, or very soft material in the same build. Or, to mix clear and colors in the same build.  Our customers use Polyjet printers to make everything from accurate medical models of organs to molds for plastic injection molding.  No other 3D Printing technology is as versatile as the PolyJet machines from Stratasys.

The PADT Sales Experience

Lots of people sell 3D Printers. We know because we have been doing it for over fifteen years. And as the technology has become more popular, more and more people are getting into the industry.  Our experience and technically driven sales approach is why customers keep coming to PADT when they have so many choices.  Our sales team is not about this months sales goal. They are about building, and more often than not, growing our relationship with customers new and old.  We are all about understanding what you really want to get done, and then finding the right combination of Additive Manufacturing system, accessories, and software that will make it happen.

That expertise comes from the fact that we have been running a 3D Printing service since 1994.  We know the real world of Additive Manufacturing.  No other reseller can bring our expertise and experience to your aid.

Support that Goes Above and Beyond

Once you purchase a system, your journey with PADT hits full swing. Our engineers will help you install, train your users, and then be there when you need us for maintenance and repair. Or simply to answer your questions.  We recently won a series of competitive situations where customers had a choice of who to hire to support their Stratasys systems. They chose PADT over other solutions for one simple reason: we know what we are doing and we really do care.  Our team has driven through snow storms, stayed with machines late into the night, and personally shipped replacement parts just so they could get customer’s machines back online and running as quickly as possible.

Talk to PADT about your Additive Manufacturing Needs

Regardless of what systems you currently have, or if you don’t have any 3D Printing capability in-house, now is the time to talk to PADT.  We have never had a better offering of solutions in terms of price, performance, and variety of capability.  We are helping universities establish labs, Aerospace companies 3D Print hardware for launch vehicles, and consumer products companies shorten their design cycle.  It may be time for you to upgrade or add a new material or technology. Or maybe you just need some accessories to get more out of the equipment you have.  Regardless of where you are in your Additive Manufacturing journey, PADT is here to help you get more out of your investment.

Exploring the Value of Multi-Print 3D Models for Medical with Stratasys & Intermountain Healthcare

PADT’s Salt Lake City office has been involved with fulfillment of medical 3d Printing of several cases where customers are exploring the value of multi-color and multi-material medical 3D models by using the Stratasys J750 or the Connex 3. One of those cases was presented at the Mayo Clinic’s Collaborative 3D Printing in Medical Practice 2018 course, which was held in Arizona this year.

An Intermountain Healthcare facility in Salt Lake City needed help with 3D printing a patient-specific anatomy, as they were looking to better their understanding of the value of 3D printing using multi-color printer beyond their existing in-house capabilities. In the picture below, Rami Shorti, PhD., a senior Biomechanical Engineering Scientist at Intermountain Healthcare, wrote:

“A patient with a horseshoe kidney and multiple large symptomatic stones, who had failed Extracorporeal Shock Wave Lithotripsy and Ureteroscopy Treatment, was used to evaluate the benefit of using different imaging modalities intraoperatively.” 

Working with us in Salt Lake City, Rami Shorti, PhD, prepared the patient-specific medical imaging segmentation, post-processing of the patient anatomy, and finally generated for us a 3D printable CAD model that we were able to print using a Stratasys Objet 260 Connex 3. Since our office is located just around the corner from the hospital, we were able to work closely with Rami to identify the colors and finish of the final part.

The Connex 3 printer was introduced in 2014 as the only printer in the world that could combine three different model materials in a single print pass. Most 3D printers can only print with one material at a time, which is one of the main reasons why this technology is preferred for medical use cases along with its added precision. In 2017, Stratasys introduced the J750, which again is an industry first, becoming the only printer in the world that can print 6 different materials at the same time.  Combinations of hard plastics and rubber materials allow for a range of shore hardness values along with the ability to mix three primary colors to print 500,000 different colors.

With a quick turnaround needed, we decided to use the Connex 3 and were amazed that we were able to print the parts in two batches. Within 48 hours of receiving the STL files from Dr. Shorti, we were able to 3D print, post-process, and deliver the parts in time for the surgeon to review the time-sensitive surgical planning guides using the mockup. To enhance the transparency of the parts, we simply applied a few coats of Rust-Oleum Clear Gloss to the 3D printed part.  Now we were able to relax and wait for it to dry.  Below is a picture of the finished products displayed at the Mayo Clinic event.

 “3D printing added a level of benefit because of its ability to showcase the stones, renal pelvis, and renal arteries and veins simultaneously through the image fusion step done in Mimics software and with the use of specific materials and contrasting colors.  In addition, its ability to be held and manipulated in space was observed to be beneficial especially for patient education.”

– Rami Shorti, PhD., senior Biomechanical Engineering Scientist, Intermountain Healthcare

PADT is excited to continue our work with Intermountain Healthcare, and grow this relationship as new opportunities arise to leverage multi-material printing.

Phoenix Business Journal: Three Posts: “It’s a mess,” Exploring Easy with Disney, and a look at Blockchain

Time does fly and I got a bit behind on posting about postings in the Phoenix Business Journal. So here are three articles we hope everyone finds interesting:

It’s a Mess

One of the most annoying aspects of modern business life is the proclamation: “It’s a mess.”  Complaining is fine, but there is no indication of what the problem is and no attempt at a solution.  Please read “Turning “it’s a mess” or “it doesn’t work” into positive change” to share my pain and explore some solutions.

Exploring Easy with Disney

In “Exploring Easy: How a visit to a Disney resort highlights the power of easy” I add to the series on how making things easy in business is just a good idea. This post looks at the pure genius of the Disney organization in making every aspect of their customer’s experience.

The latest tech trendiness is a technology for keeping track of transactions called Blockchain. Its popularity stems from the fact that it has some significant advantages over traditional ways of recording transaction.  It is also popular because people have made millions out of thin air using it to track the creation of cryptocurrency. “Beyond the hype, understanding blockchain – Part 1” I share what I learned about the technology that is Blockchain.

PADT Intern Wins NASA and ASME 3D Printing Competition

We are very proud of our Additive Manufacturing intern Austin Suder who just won Future Engineers “Two for the Crew” Challenge, presented by the ASME Foundation and NASA.  The challenge asked to invent a multifunctional object that combined two items into one for 3-D printing by crew members aboard the International Space Station (ISS). As a winner he will receive a trip to Washington DC, a MakerBot 3D printer donated to the orginization of his choice, and best of all, his design will be printed on the ISS and used by the astronauts.

Austin’s design was a Carabiner Tool Clip that combined a way to easo;u secure a tool and hold the sockets and drivers that the tool needs.  After designing the part he then used simulation to iterate on the design with virtual testing, and then he 3D Printed a prototype on his home 3D Printer. Austin started this project by researching what problems the astronauts faced. He found that a big problem was that tools would drift off in the micro-gravity environment of the station.  This was annoying when they are working inside the station, and a critical problem when they are on a space walk.  He also realized that they used a separate “holder” to keep the sockets and screw driver heads that the tool needed. Using this knowledge he developed a simple to operate carabiner to secure the tether on the hand tool to the astronaut and then use that same part to hole the sockets and drivers.

But he did not stop there. He also learned what he could about the MadeInSpace 3D Printer  that is on the station, and adapted the design to make sure the printer could make easily. Austin then used simulation to make sure the design was strong and robust. Then he printed his samples on his own home printer.

Local Phoenix station ABC15 stopped by PADT yesterday to interview Austin and here is their story:

Much of Austin’s knowledge and skill comes from his involvement in his school robotics team, and he will be donating the MakerBot he won to that team.

We hare very proud of Austin’s accomplishments.  He works at PADT as an intern in the Advanced Manufacturing department focused on 3D Printing, doing CAD, running the machines, cleaning parts, and being our in-house expert on desktop 3D Printing.  He will be graduating from High School this year and attending ASU as a Mechanical Engineer.  We can not wait to see what he does next!

MSU Denver Shows off their Additive Manufacturing Lab

In November of last year we did a press release on new Additive Manufacturing Laboratory at Metropolitan State University in Denver. Since then all of the partners have been hard at work getting the lab up and running.  Last week MSUD released an interview with the University President about the lab as well as a tour of the lab.  It is a great look at how academia and industry are working together to push advanced manufacturing forward. Not just on equipment, but also with internships and value added engineering at the university.

Take a look:

PADT is proud to have been a key member of the team  and a continued partner for the lab along with Stratasys.

If you want to learn more about how PADT can help your company or university create partnerships like this or leverage 3D Printing in other ways, please contact PADT.  We love this stuff!
