Diving Into Additive Manufacturing With 3D Pen Technology

Tennessee Tech AM-WATCH project offers virtual workshop showcasing what’s possible with a 3D Pen.


In early January, Tennessee Tech University offered a special Virtual AM-WATCH Studio Workshop with its full day seminar: Diving into Additive Manufacturing Practices via 3D Pen Technology. In this course, Kim Grady, an accomplished NSF Principal Investigator and  Instructional Technologist, created and conducted the 3-hour workshop for high school and technical college educators interested in teaching 3D printing skills.

Kim uses the 3Doodler 3D pen in this workshop to demonstrate 3D printing concepts such as layering, joining, geometry and measurement, and adding function to an object. If you are asking: What is a 3D printing pen? — it is a device designed to allow you to make  PLA or ABS plastic 3D objects without a 3D printer. Essentially, the 3Doodler Pen is a handheld extruder. 

The original 3Doodler originated with a 2013 Kickstarter (crowdfunding platform) project that made more than two million dollars above the fundraising goal. The company offers a variety of pens including easy to handle models for young hands and advanced control models for professionals. 

Of course, there are other makes and models of 3D pens on the market and we will list a couple of reviews that share pros and cons for many of them. This will help you find the best 3d printing pen for your needs or your students’ needs. If you are searching for products and ideas, consider also using “3D printing pen” or “3D drawing pen” as near-synonymous terms. Many consider the 3D pen to be a young cousin to the 3D printer, a handheld one, at that. 

You can watch the full 3-hour YouTube video, “Diving into Additive Manufacturing Practices via 3D Pen Technology,” also embedded here:

Tennessee Tech, through its AM Watch project and team, sponsored and delivered the workshop in collaboration with TEAMM’s Principal Investigator (PI) Mel Cossette and Kim Grady. Kim has been a MatEdU partner since 2004, an active participant for many NSF grants and continues to develop hands-on curriculum for a wide range of educators. She has produced downloadable courses and materials here on TEAMM as well as on MatEdU, including:

You also can find the complete collection of educator resources at the TEAMM Module page and on the MatEdU Module page (well over 100 modules you can download in PDF and PPT formats).

Dr. Ismail Fidan, who leads the AM-WATCH program, opened the workshop exploring and explaining how Additive Manufacturing is “a new way of making.” Graduate students followed Dr. Fidan’s remarks: Seymour Hasanov gave tips on the fundamentals of design, followed by Ankit Gupta highlighting various materials for AM, with Tyler Edwards explaining 3D Printer Parts and Operating Principles. 

Kim Grady’s three-hour session was packed with detailed explanations for how to use the 3D pen to teach complex 3D printing concepts. She defined and demonstrated the basic concepts then guided the participants, virtually, through hands-on application.  

Participants started with the basics of extrusion by writing their initials and fabricating basic shapes. To get a solid grasp on how wire framing and layering is used to fabricate real-world objects from PLA filament; squares were joined to create a hollow cube (shown below) and half spheres were joined to create a hollow ball. To illustrate and get experience with design, snowflakes with repeating hexagon shapes were constructed. “Real” 3D printing vocabulary and concepts were stressed throughout, making this workshop unique to any other 3D pen tutorial or workshop currently available.

As a “final project,” participants were challenged to apply what they learned to add function to their objects. The cube and ball concepts were used to fabricate a ball and socket, and the snowflake’s repeating shapes design concepts were applied to fabricate functioning gears. 

Final project results and ideas for how to use the 3D pen in your classroom can be viewed on the YouTube link above.

  • You can visit the 3Doodler page directly. The New York Times Wirecutter review “The Best 3D Pen” recommends it highly as well. In fact, they do not list others and only recommend this one – a significant statement for them. There are educator-specific classroom kits under their “Schools” tab. Basic sets start around $169 (but is on sale frequently for around $89) and a Pro set is available at $199.

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).

3D Printing Jobs Are Part Of The Future

In November 2020, MatEdU News (our sister publication focused on Materials Education and Materials Science), published a story about the second AM symposium organized by DREAM (NSF Award #1902501). You can read about it here: Chippewa Valley Technical College Offers Additive Manufacturing Symposium.

Advanced Technological Education (ATE) is a core part of our work here at AM News and we encourage you to visit some of our other recent posts about training and degree programs to help you learn about the perfect job or career path and educational programs that will get you there. Take a look at this lecture series: Digging Deep with Online 3D Printing Lectures.

 

Digging Deep With Online 3D Printing Lectures

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.
