    Thought this was very imformative, SLA looks like just as much or more of a burden..still needs crazy support..etc. and seems expensive.

    I'm gonna stick with my robo3d and rep2 for now.

    I work with some guys that do character modeling, and they dont like the FDM printers, one of them has the form 2. and loves it.

    I mostly print functional stuff that I use so not characters..etc. and I dont have a problem with FDM printers in most cases.

    What is it that shapeways uses? etc? I have seen videos where its in powder and prints metal. I know SpaceX has a Titanium printer that can print ridiculous stuff with no support.. Guess us normal folks wont be having that type of tech for years?

    Most commercial concerns use SLS (Selective Laser Sintering) printers. They may also have other technologies running at the same time. SpaceX uses the same tech with Titanium powder. That is why there is no need to print any support, the powder bed itself supports the model 100%.

    There was some H.S. student in Germany that came up with a SLS printer that I think was around $3500 to make. So it is not unattainable.

    SLA is much the same chemical/technical process as DLP except one uses the laser to draw the layer and the other exposes the entire layer at a shot. Whether the printer prints top->down or bottom->up (right side up or upside down) all matters :)

    SLS is a much nicer approach, I just have not yet gotten bold enough (or enough extra cash) to want to build one...
