Creating 3D Printed Text Masks

I’ve been refining my light printing technology, based on the “Do it for Josh” light (which is still available by the way). The first version used a printed mask and transparent letter inserts that were stuck inside it. It worked OK but it was a pain to assemble and the letter inserts kept falling out.

So I’ve designed a new version in which the letters and the masks are all printed in one. The clever (I think) bit is that I print the first few layers using transparent filament and then switch to solid during the print. I quite like the effect, and it means that I don’t have to assemble anything.

If you’ve got a 3D printer you might like to experiment with changing filament during the printing process, most printer firmwares have an option to do this and you can get some quite nice effects.
