The Form 1+’s display will be urging you to close the cover – to prevent too much light falling on the resin which would cause it to harden prematurely. ![]() Once that’s done, it’s time to pull on the included rubber gloves, get out the photosensitive resin and carefully fill the tank up to the arrow on the front. This is what the laser shines through, so keeping it free of fingerprints and dirt when sliding it into place is imperative. The resin tank is made of the same light-blocking orange acrylic as the Form 1+’s casing, and has a clear, silicone-coated base. But before you start printing you’ll have to load the resin tank and build platform. The machine itself is hooked up to your computer via USB and controlled via the Formlabs PreForm application. Getting started is part plug-and-play, part science experiment. In fact, it looks like it belongs in a high-end laboratory somewhere – the company name makes sense now. More than most other consumer 3D printers, even the very slick FDM-based CEL Robox, the Formlabs Form 1+ looks like a finely honed machine rather than a grown up garage project. ![]() It’s a well-honed industrial process that has always been restricted to much larger, more expensive commercial machines. So how does SLA work? It involves building up a print, layer by layer, using a laser to cure (harden) resin that is sensitive to UV light. ![]()
