3D Print Custom Coaster


Introduction: 3D Print Custom Coaster

About: An engineer, seamstress, cook, coder, and overall maker. Spent a summer at Instructables; got a degree in E: Neural Engineering at Olin College; made a microcontroller (tessel.io); now thinking about climate...

Quick & easy- I made this in Google SketchUp in about 5 minutes (they have a 3D text tool), then converted file types and printed on a PP3DP 3D printer with ABS plastic.

I'm trying painting it to make it prettier- anyone have (better) suggestions for coloring extruded ABS plastic?

    How detailed is the printing? Could you design in tiny grooves you could fill with something colourful?

    Actually, it comes with tiny grooves built in- the ABS plastic makes a ridged surface.
    Painting with acrylic paint worked surprisingly well, though I'll be really impressed if it stays on- and the texture is kind of weird.
    I was going to try enamel to smooth out the surface while coloring it, but there were lots of "keep away from heat" and "toxic" labels, so I thought perhaps not the best for a coaster..

    Speaking of enamel, how about nail varnish?

    I saw on the shelves of a local store, there are varnishes now that make odd textures as they dry, and even one that makes patterns in the surface if you hold a magnet over it as it sets!

    Very cool! I'll have to check it out.
    For hot things, I'm still a bit concerned about toxicity, but I have some other 3D print things coming up...
