I have been happy that folks have been rediscovering my MAKE article “Skill Builder — Finishing and Post-Processing Your 3D Printed Objects“, if anything to share the 3D filament friction welding techniques that I introduced, inspired by a project from the Ask Fran engineering vlog. Well, here’s another excellent post and video from Scorch Works also inspired from that Fran video — I really enjoyed it!
And one note for those who would like to explore this stuff. If you can get one, a faster rotary tools such as a Foredam can offer even more approaches to friction welding, and a wider range of materials (including acrylic rods).
…A couple of years ago Fran posted a really interesting video demonstrating friction welding. Fran used a cheap harbor freight rotary tool and some plastic (styrene) rod from a craft store. Her demonstration showed how strong friction welded joints are. Friction welding has been bouncing around the back of my brain ever since. Lately I have found a couple of applications for the friction welding technique. Having recently purchased a fused filament 3D printer (PrintrBot Simple Metal) I have some failed PLA 3D prints laying around. I also happen to have some ABS scraps and some 3mm injection molded ABS rods from another project. Experimenting with these materials I have found that friction welding works well for both ABS and PLA. As part of my experimentation I repaired a failed Maker Faire Makey figure. The following video captures the process. (I have since printed a successful Makey Robot on my Printrbot simple Metal)….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
