SLA, DLP, LCD and CLIP printers
- [Female Voiceover] Resin 3D printers fall into two big categories. Ones that use a tray or a vat of light sensitive resin, and harden the resin with a laser and those that use Inkjet like technology to spray resin onto a previous layer. This movie will focus primarily on the types that use a tray or vat of resin. Even within that category, there are several different technologies. We'll walk through each and their relative merits. - [Male Voiceover] The resin printer technology that's been around the longest is SLA, which is acronym for Stereolithography Apparatus. SLA printers, like this Formlabs one, have a tray of resin that's illuminated by a laser through the clear bottom of the tray. There's a laser galvanometer below the tray, which is a device that rotates mirrors to move a laser spot across the machine's X and Y axis. The X and Y axis define the plane of the build platform. When the layer's done, the print…
