#Sunrise Version 2.0 – an #opensource #DLP #3DPrinter project by BQLabs. The Sunrise Project is a research project, that aims to design an Open Source hackable DLP based 3D printing system.
DLP 3D Printing uses photopolymierizing resin to craft the parts. Parts generate layer by layer as they are cured by a projector that outputs the cross-sections of the part, into the resin. There are various mechanical structures that can be used to achieve this.
This machine has what is called a Bottom-Up structure. It has a vat, with transparent bottom, filled with resin. Underneath, an upward pointing DLP projector shoots light through the bottom window. The light striking on a downward pointing build surface cures the resin, forming a new layer. Repeating this process, curing one layer below the previous one, ends up crafting the whole part, upside down.
