Publications

Although most of what PADT publishes is here on this blog, we do get asked to submit articles to periodicals, journals, blogs, and other external publications.  We also get interviewed every once in a while. This part of the blog will give brief summaries of what was published and a link to where they are published.

If you are not up for reading right now, you can also view our video content on YouTube here.

Phoenix Business Journal: ​Um, the coffee machine needs more water and 5 rules to improve your user interface design game

Posted on January 12, 2017, by: Eric Miller

Usually getting coffee is just getting coffee, but a recent trip turned into some deep thoughts on user interface design.  "​Um, the coffee machine needs more water and 5 rules to improve your user interface design game" explains my encounter with the office caffeine dispenser as well as five key rules that everyone should follow when developing a user interface for a product.

Phoenix Business Journal: ​Is acquiring disruptive innovation good for everyone?

Posted on January 6, 2017, by: Eric Miller

It seems like the trend these days is for large companies to not do R&D in house. Instead the let StartUps develop innovation and then buy it when the market proves it out.  I had to ask myself "​Is acquiring disruptive innovation good for everyone?"  I don't think it is and explain why in this week's blog post.

Phoenix Business Journal: ​When did we start thinking amateurs were a good idea?

Posted on January 3, 2017, by: Eric Miller

We have a problem. At some point it become not just OK, but prefered to count on amateurs to tackle difficult problems. In politics and in business it is a trend to go with people who have no background and no experience. Seeing the results, I a not a fan.  In "​When did we start thinking amateurs were a good idea?" I look at this disturbing reality, why it is a bad idea, and offer some suggestions on turning things around.

Metal AM Magazine Article: Modeling the Mechanical Behaviour of Additively Manufactured Cellular Structures

Fig 1. Metal AM Magazine Cover: Winter 2016 (Vol. 2, No. 4)

Metal AM Magazine publishes an article by PADT! Our 10-page article on "Modeling the Mechanical Behavior of Cellular Structures for Additive Manufacturing" was published in the Winter 2016 edition of the Metal AM magazine. This article represents a high-level summary of the different challenges and approaches in addressing the modeling specific aspects of cellular structures, along with some discussion of the design, manufacturing and implementation aspects associated with AM. Click HERE for link to the entire magazine, our article starts on page 51. Digital editions are free to download. Swing by PADT in the new year to pick up a hard copy or look for it at our table when you visit us at trade shows. To stay in touch with the latest developments at the intersection of AM and Cellular Structures, connect with me on LinkedIn, where I typically post 1-2 blog posts every month on this, or related subjects in Additive Manufacturing.

Phoenix Business Journal: ​How far away are we from 3D Printing the androids on ‘Westworld?’

Posted on December 7, 2016, by: Eric Miller

A bit of a twist for this weeks Phoenix Busines Journal blog post... "​How far away are we from 3D Printing the androids on 'Westworld?'"  In discussing this great new reboot of a classic, and yet another fantastic cautionary tale from Michael Crhichton, a couple people started wondering how far off the tech in the show is.  The answer, well you will have to read the article.

​Phoenix Business Journal: The Arizona startup market needs bridge funding for growth

Posted on November 30, 2016, by: Eric Miller

Just-Published-PBJ-1The state of Arizona has made some great strides in creating a vibrant and growing startup community. Only a few things are missing and the big one right now is that "The Arizona startup market needs bridge funding for growth" Check out the article to get my feelings on the topic, what our problems are and how we can fix them.

Phoenix Business Journal: Publishing your own book, technology makes it easy

Posted on November 30, 2016, by: Eric Miller

Just-Published-PBJ-1A few years back PADT turned one of our training courses into a book, and even though it is about an obscure programming language for a software product that is only known to our industry, it has done well. In "Publishing your own book, technology makes it easy" I review how truly easy and affordable on-demand self publishing can be.

SFF Symposium 2016 Paper: Predicting the Mechanical Behavior of ULTEM-9085 Honeycomb Structures

Posted on November 21, 2016, by: Dhruv Bhate, PhD

Our work on  3D printed honeycomb modeling that started as a Capstone project with students from ASU in September 2015 (described in a previous blog post), was published in a peer-reviewed paper released last week in the proceedings of the SFF Symposium 2016. The full title of the paper is "A Validated Methodology for Predicting the Mechanical Behavior of ULTEM-9085 Honeycomb Structures Manufactured by Fused Deposition Modeling". This was the precursor work that led to a us winning an 18-month award to pursue this work further with America Makes. Download the whole paper at the link below: http://sffsymposium.engr.utexas.edu/sites/default/files/2016/168-Bhate.pdf Abstract ULTEM-9085 has established itself as the Additive Manufacturing (AM) polymer of choice for end-use applications such as ducts, housings, brackets and shrouds. The design freedom enabled by AM processes has allowed us to build structures with complex internal lattice structures to enhance part performance. While solutions exist for designing and manufacturing cellular structures, there are no reliable ways to predict their behavior that account for both the geometric and process complexity of these structures. In this work, we first show how the use of published values of elastic modulus for ULTEM-9085 honeycomb structures in FE simulation results in 40- 60% error in the predicted elastic response. We then develop a methodology that combines experimental, analytical and numerical techniques to predict elastic response within a 5% error. We believe our methodology is extendable to other processes, materials and geometries and discuss future work in this regard.

Phoenix Business Journal: What does living in a post-fact world imply for business?

Posted on November 11, 2016, by: Eric Miller

Just-Published-PBJ-1One of the many realizations to come from this election cycle is that telling the truth really doesn't matter anymore, we live in a post-fact world where you can say or post anything and ignore proof that it is wrong.  In this week's post, I ask: "What does living in a post-fact world imply for business?"

Phoenix Business Journal: It’s time to stop putting innovation on a pedestal, and praise getting stuff done

Posted on November 3, 2016, by: Eric Miller

Just-Published-PBJ-1Innovation has become almost a magic word, and in the startup world innovators are given demi-god status. We like to think that there are people out there who just come up with ideas that change the world. Reality is that we kind of overkill the whole thing and "It’s time to stop putting innovation on a pedestal, and praise getting stuff done."  Channeling a little Andy Rooney on this one.

Phoenix Business Journal: Pitching a startup well: What I learned while competing for the Unicorn Cup
