Painting your 3D Prints

We can all agree that scheduling a little time for post- processing typically isn’t a bad idea. Since prints aren’t always show-room ready, here’s a guide that covers the basics of painting PLA and ABS 3D prints. From paint type to smoothing to priming, this is everything you need to know to be fully prepared for this design stage. Painting shouldn’t be an afterthought and since there isn’t one right way to do it, learn more to discover what effects work best for painting your 3D prints.

“Usually, you have to decide whether you’re going to use an airbrush, a brush, or canned spray paint. While a brush is cheaper compared to the other options, it can be tough to accomplish an even coat of paint, with noticeable “blobs” in some spots and the underlying color appearing in others. An airbrush, on the other hand, is costly and typically has a steep learning curve.

Sanding smoothens deformities and can be time-consuming depending on the size of the print or finish you are aiming for. Sand down the support marks and make sure you’ve removed any filing or tooling marks.

Priming turns your 3D print into a professional product and makes the painting process effortless by creating a flawless final surface. Priming is necessary because paints will never hide all the flaws, especially when you‘re aiming for a near-perfect object.”
