This is not the first time that this type of 3D printer has been presented, but its concept remains as spectacular as ever.
While "traditional" 3D printers are presented as an extrusion head which assembles a 3D structure by depositing successive layers on a cradle, CLIP (Continuous liquid interface production) technology relies on reverse manufacturing, the coin magically emerging from a liquid container.
Carbon3D indicates that the process offers a major advantage over plastic extrusion printing technology: time. His machine is thus able to multiply the printing speed from 25 to 100 while offering better precision in order to offer finished objects.
The system (DLP / SLA) has been known for a long time: a cradle is positioned on the surface of a resin tank which responds to UV light. Below, a projector sends an image through an oxygen-permeable window.
The projected image makes it possible to polymerize the resin, which solidifies in a few moments. Depending on the exposure time of each projection, the thickness of the solid resin layer is defined. All you have to do is rotate the images in sections, and raise the cradle to get the part out of the liquid. The advantage of this technology is that it allows continuous printing, thanks to a fluid sequence of all procedures.
Carbon3D is currently playing the buzz by comparing its machine with the famous T-1000, the liquid metal terminator capable of going from the puddle stage to the dreaded cyborg.
