If you’ve ever tried printing ninjaflex on a printrbot, you may have notice a small problem. It doesn’t extrude so well. TPE material is so flexible that the filament actually buckles just before reaching the hotend. The drive gear and the hotend are so far apart that the filament can actually tangle, and thats no bueno!
Our 3D printed filament upgrade eliminates this problem by guiding the filament directly to the drive gear, removing any room to buckle.
For optimal printing quality, set the temperature of the extrude to 250. Disable retraction while extruding and decrease the travel speeds down to 30%.
Part is available on Thingiverse for free.
Full Tutorial on The Adafruit Learning System
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! 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!
