3D Printing Product Development Decisions with Dr. Jennifer Loy

Dr. Jennifer Loy presents at the TTU Golden Eagle Additively Innovative Lecture Series

On Feb 18, Dr. Jennifer Loy from Deakin University in Melbourne, Australia, will present the 3D Printing Product Development Decisions webinar via the Tennessee Tech additive manufacturing lecture series.

Join from anywhere, via the Zoom video platform: tntech.zoom.us/j/432789883 at 11AM Central Time on Thursday, February 18.

Each semester, Dr. Ismail Fidan and team coordinate the well-respected TTU Golden Eagle Additively Innovative Lecture Series. The Spring 2021 series kicks off with Professor Jennifer Loy who has taught industrial and product design for many years, and began her career in manufacturing when efficiencies were driven by standardization, but is now a convert to the unique capabilities of additive manufacturing (AM), presenting in this talk starting points on how manufacturers could approach integrating the technology into their business from a product design point of view.

Jennifer will share tips to help existing and new businesses understand what to 3D print, where it could be appropriate for them, and when it is not. Many businesses are finding that logic built up through years of conventional manufacturing practice and process no longer applies and it can be problematic when trying to reach an objective decision on what to make with AM and how to integrate it into production and business practice. Jennifer believes that in order for technology adoption to be successful, our understanding has to move beyond engineering to product design, production practice and logistics.

The aim of this short, illustrated presentation is to provide some initial guidance for a company considering adopting AM and starting points for evaluating product design options. These starting points and practical, realistic strategies and considerations are also the subject of a future book, going into greater depth, due to be published by Routledge in 2022.

Professor Loy introduced additive manufacturing into product design at Griffith university, initially at third year, then second and finally first year as she became convinced that to exploit its characteristics, product designers needed to explore its capabilities prior to those of conventional manufacturing. Jennifer is now Professor of Additive Manufacturing in the School of Engineering at Deakin University, Australia, where she leads a Masters’ specialization in AM.

Additive Manufacturing Certificates

Most people within the industry use the term “additive manufacturing” interchangeably with 3D Printing (although the latter is more popular and used widely in student and professional discussions). Think of an additive manufacturing certificate as a mini “3D printing degree.”

Due to current job and workforce trends, there is a shortage of technicians in almost every technical career specialty in the USA. Educational institutions, particularly 2-year institutions, are working hard and smart to develop new programs for technicians of all types. This workshop will help you get a basic understanding of the training needed to get started in additive manufacturing.

DREAM is hosting the third virtual Symposium on Additive Manufacturing on Friday, February 12th at 9:00 A.M – 12:00 P.M. CT. Supporters include Dassault Systèmes (SolidWorks), Ashley Furniture, Zeiss, and Desktop Metal.

You can find recorded videos of hosted symposia, developed modules, and more by visiting the NSF DREAM Project website. NSF will provide a small stipend for your time (in this workshop symposium) if you are a high school, middle school, or elementary school teacher ($100).

Tennessee Tech University YouTube Channel Featuring the Golden Eagle Additively Innovative Lecture Series since 2016.

The College of Engineering at Tennessee Tech recently completed its well-known Golden Eagle Additively Innovative Lecture Series for Fall 2020. Under Dr. Ismail Fidan and his team, four experts — from nearby Somerset Community College in Kentucky to institutions spanning the globe in New Zealand, Norway, and the Netherlands — presented this semester on advanced Additive Manufacturing topics.

With 45 lectures recorded since the Spring semester of 2016, there is a range and depth available for just about anyone interested in learning about Additive Manufacturing. We wrote about the Tennessee Tech Announces Fall 2020 Additive Manufacturing Lecture Series as the school year got started. Despite COVID-19 shifting the world into online classrooms, Dr. Fidan has been using this virtual method, via Zoom, since the start of the program. One could definitely say he is an early adopter and visionary for making learning accessible and increasing TTU’s Engineering student access to world-renowned experts.

Early in 2020, the team decided to launch a YouTube channel as a way to share all of these lectures to an even wider audience. You can access the full Additively Innovative Lecture Series Archive, but we list out the titles below so that you can get an idea of the topic and niche diversity. On the archive page, each title takes you directly to the YouTube video. Perusing the list on the YouTube channel is not as straightforward, in this editor’s opinion, and so your time may be better spent picking from the list of video links from the archive directly.

Again, Bravo to the TTU team and Dr. Fidan for a semester filled with knowledge sharing and deeper insights into what makes Additive Manufacturing (aka 3D Printing) useful, valuable, and world changing.

**Oh, and don’t forget to subscribe to their new YouTube channel.

Mass Production And Decision Making With Low Cost Additive Manufacturing

With over 7,000 face shield assemblies 3D printed, 1,000 ear savers (that make it possible to get a mask strap off the back of your ears), and 272,000 grams of filament used, Somerset Community College’s (SCC) Additive Manufacturing Center (AMC) stepped up in a major way to 3D print personal protective equipment (PPE) for Kentucky’s first responders in this COVID-pandemic time of need.

Professor Eric Wooldridge recently spoke at the Tennessee Tech University Fall 2020 Golden Eagle Additively Innovative Lecture Series on September 27, 2020 to encourage future 3D printing business owners and other academic institutions how they might leverage 3D printers in the future. For the SCC AMC, the majority of their printers cost less than $415 which helped them build a 24/7 production line of dozens of 3D printers, using two or less operators per day.

Wooldridge and SCC have received funding from the USDA Rural Development program as well as the National Science Foundation EPSCoR and ATE programs. The funding has been instrumental in building out a successful 3D printing training program as well as a robust production facility, as demonstrated by answering this call to serve first responders with PPE. The SCC Additive Manufacturing (AM) goal is to give Kentucky manufacturing an edge by helping to raise up a fully skilled AM-skilled workforce. A task that the SCC team seems well-prepared for after this PPE experience. 

In fact, that’s what the “Mass Production And Decision Making With Low Cost Additive Manufacturing For Institutions And Small Businesses” webinar offered. It gave an inside look at how a small team could scale up a 3D printer production line as a way to make new products. In the talk, Professor Wooldridge offered a variety of insights and technical tips as he walked attendees, including industry representatives, through decisions the AMC made, including mistakes they quickly corrected, in printing thousands of shields and parts. 

Low Cost Additive Manufacturing (LCAM)

First, what is a low cost 3D printer? SCC’s goal is to take a sub-$600 printer and show business owners how to make money with it. Once they demonstrate that, he sees owners take it from there. Low cost equipment can create a high quality production line. If they have 3D printers and 3D skills, it leads to innovation.

Before you jump in and start printing. Wooldridge believes you need to look at three main areas:

  • Design
  • Cycling
  • Maintenance

Part of these three areas involve asking four key questions (any company or organization would want to ask these):

  1. How big is your team? (Small businesses are often under-staffed, so this is important)
  2. What is your design flavor? (If you like to only create the models, that won’t work if you don’t like to print, too). You have control of the layout on the printer, the printer speed, are there non-essential features that are essential? 
      • Within design — you have to think about your production. 
        • Are you a “Fast Ninja”?  
        • Are you a “Slow Stacked” approach? 
        • Or in the middle is the “Flat Spread” type?
  1. Production cycling, what do you most care about?
  2. Do you want to do proactive or reactive maintenance? Which one will minimize your downtime? 

Wooldridge digs in and keeps the talk moving quickly with rapid fire answers to his questions. In this short 30-minute lecture, you will get lots of very specific technical advice in addition to broad ranging issues you should think about. 

An example: In the section on Cycling, he points out that one of the biggest enemies is runout; running out of filament. “Runout sensors that warn you that you are ‘about to run out’ of material are cool, but not the answer. The idea that your printer would warn you that you were running out of filament was not helpful in the middle of 20 or 30 printers going at once after 15 hours of run time. Quantity is the solution — getting large orders of filament with 3kg or 5kg rolls — what we call the Texas Size rolls (that’s where we ordered them from),” Wooldridge said.

The SCC team naturally found it was super rewarding to be able to help their community. Wooldridge closes the talk with how it was wonderful to be in a position to respond “with Additive to support our regions, we sent across state lines as well. It was great to be in the middle and answer that call.” 

Ultimately, he concludes: “This pandemic has been a real turning point for Additive. It has made people realize what is possible. And you can see it in the industry response. You see how many companies are starting to now buy into higher-level equipment, buying up printers. The number of print farms that are being setup is drastically increasing. People have realized that this technology has the potential to step in and fill gaps wherever they are. Or allow someone to startup with a brand new business with hardly any infrastructure to begin with, in terms of manufacturing.”
