From 3D printing a rapid prototype to casting high performance urethane plastic, this video demonstrates how to use Mold Star 20T to make a silicone mold of extruded PLA. Mold Star 20T has virtually no shrinkage and a fast, 30 minute cure time.
Benefits of Making a Mold of 3D Printed Prototypes:
* Faster production of multiple copies.
* More material options for finished part.
* Ability to cast in a wide range of colors and finishing effects without specialized equipment or additional print media/filaments.
Benefits of Mold Star 20T Silicone:
* Easy to use 1A:1B by volume mix ratio: no gram scale necessary.
* Low viscosity: no need to vacuum degas.
* Make molds fast! Rubber cures in 30 minutes.
* Ultra low shrinkage.
* Very long library life.
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!
