[QUOTE="Wainwright, post: 305562, member: 20457"] Comparing resolution on DLP or LED masking type printers to a SLA laser based printer is a bit of a difficult task and claiming its 2x better is really a stretch. SLA, and the Form 3, draws the edges of parts in a sweeping motion using a 80 um laser point, its similar to drawing a line with a pencil or pen. DLP or LED mask type printers rely on pixels, squares, to create edges. So if you have a line that cuts through the center of a pixel it needs to average or round up or down to the nearest edge. Envisiontec uses anti-aliasing technology that allows an edge pixel to be half power making it closer to reality. But, as for surface finish and printing the edge of a part SLA is superior to any pixel based system. That all being said, DLP and LED masking type printers are much faster, that is their true advantage. The Micron does sound a bit too good to be true. A buddy of mine bought one and I asked him to print some test parts for me to scan and analyze but he never got around to doing it for me and haven't heard anything from him since. I'll try to follow up with him again and get a users opinion on it. Certainly looks promising. I think we are in a moment in 3D printing in dental where there are so many options its almost like a bubble. In 3 to 5 years I would guess the amount of companies making 3D printers in dental will greatly reduce to around 5.

One of the many reasons I feel confident with Formlabs and I could say the same about 3DSystems, is its a big well established company that isn't going anywhere anytime soon.
