Sugru Overmolding Using 3D Printed Molds #3DThursday #3DPrinting

Andreas Bastian shared a handy tutorial for Sugru overmolding using 3D printed molds that simultanteously leans on a desktop 3D printer for creating a structural armature and for mold design to extend this structure with other materials:

Having different mechanical properties in different regions of a part can be extremely useful, especially when compliance or textures are involved.

As an experiment in improving the grip of the Raptor Hand, produced by a team of designers in the e-NABLE 3D printed prosthetics community, I designed a mold and modified the Raptor distal phalange to allow for Sugru overmolding. Sugru is an air-cured silicone material that is typically packaged in 5gram packets and is quite durable and grippy when cured. After molding and trimming, the Sugru fingertip is secured bonded to the distal phalange and provides some additional friction compared to the original PLA surface….

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!
