Suspended Depositions: Rapid Prototyping Process


Wed, Jul 24th, 2013 11:00 by capnasty NEWS

Conceived with the idea of having a device capable of handling rapid prototyping, Suspended Depositions envisions a robot that injects and suspends a "light-curing resin in a gelatinous medium" permitting 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).
