Building a "3D Printer"?

[makisekurisufcker]

What I want to do is set up a landing gear, projector and project a small ship to have it built semi-automatically. I tried making something like a hangar with welders connected to materials to build it but for some reason or another it does not seem to build. Can large ship welders not interact with small grid projectors? I know there is a limited range of the welders and nothing can be clipping but from what I can tell they are not so is there a problem elsewhere?

Not sure if it's what your problem is but you need to have a bit of (small grid) scaffold touching the hologram. The piece it touches will turn opaque and the print will start at that spot and go out from it. Also, unless the ship you're printing is very small you will need to articulate the welding heads with pistons.
