Brian Harms of NSTRMNT is exploring a new way to 3D print using resin printing methods by using a robotic arm to inject the resign into precisely the intended place to deposit material within a suspension:
This project aims to blur the line between processes of design and fabrication in the context of rapid prototyping by increasing the fluidity of the fabrication process through coordinated material and robotic processes. The project exploits feedback loops that allow the process to be used as a live generative form-finding tool as well as a method for reification of designed objects.
By injecting and suspending light-curing resin in a gelatinous medium, one is afforded the ability to shape freeform objects without the need for molds or other subtractive manufacturing processes that would otherwise be necessary. The gel acts as an omnidirectional support material which is reusable, so there is no wasted material.
One major distinction between this project and other rapid prototyping processes is the ability to utilize 3D vector-based toolpaths. Virtually all other processes use paths generated via contouring a digital model, and rely on the hardening of each successive layer before being able to move on to the next.
The suspension of resin in space without added support material allows for the ability to navigate and fabricate directly on and around other existing objects within the Gel, as well as the ability to observe the process from any angle. The suspension of time in this process allows for tool changes, manual injections, on-the-fly robotic injections, multi-material injections, live modification of the digital or physical model, and the ability to physically “undo” (resin removal via suction or scooping).
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!
