There has been a lot of progress in 3D printing, but one area that still needs modernization in terms of cost and efficiency is how to paint complex 3D printed objects.

 .

Researchers at Rutgers University believe they can advance this endeavor with a new way to paint objects, such as lightweight frames for aircraft and biomedical stents, that could help save manufacturers of these products time and money.
