3D printed parts dunked in acetone vapor produce professional finish

TrenchPhysics documents his experiments with taking objects created on his 3D printer and dunking into a bath of acetone vapor to produce a professional finish. 3D printers produce objects by printing them from the ground up one layer at a time. This causes every printed object to have visible ridges on it. The acetone vapor causes the outside layer of the 3D part to fuse together, eliminating the ridges and creating a uniform smooth surface. The end result makes the part very shiny.
