3d printing

[usmchono]

has anyone every used or built stuff from a 3d printer. just wondering how pain adheres to it and how to rescale stuff to make out of a 3d printer.

The u.v. curable resin I use to print my parts will take all the different kinds of paint well. They adhere well without using primer.

Hey Eric, do a search. The button is in the upper rh corner, under your user name. There are a LOT of discussions on the site about 3D Printing.

The 3D printed parts are no different then regular molded plastic parts in how they except paint. The biggest issue is getting them smoothed enough to look good under the paint. I do a lot of 3D modeling and have had many parts 3D printed thru Shapeways.  A cheap desktop printer is not going to have the resolution needed to print a good quality part in 1/25th scale. Using the high end printers at Shapeways is the most cost affective way to get the parts printed in a quality good enough to finish for a model part.

 The other problem is, if you don't have 3D modeling software, is getting the exact part you want replicated in 3D. In order to print a part you have to have a 3D model to pull the STL files from the printer uses. The files don't grow on trees and that is what most people seem to forget when looking into getting a printer. If you can't model it, you can't print it.
