The Zortrax Apoller is a Smart Vapor Smoothing device that uses solvents to smooth the surface of 3D-printed objects. The resulting products look like they are injection molded and all of the little lines associated with FDM printing will disappear.

The system uses a microwave-like chamber that can hold multiple parts at once. The chamber atomizes the solvent, covering the parts, and lets the solvent do its work. Once its done it then sucks the excess vapor back into a collection chamber. The system won’t open until all of the solvent is gone, ensuring you don’t get a face full of acetone. This is an important consideration since this is sold as a desktop device and having clouds of solvent in the air at the office Christmas party could be messy.

“Vapor-smoothed models get the look of injection-molded parts with a glossy or matte finish depending on the filament used. With a dual condensation process, a 300ml bottle of solvent can be used for smoothing multiple prints instead of just one. This efficiency means that the combined weekly output of four typical FDM 3D printers can be automatically smoothed within one day without loss of quality,” the company wrote.

Given the often flimsy structural quality of FDM prints, this smoothing is more cosmetic and allows you, in theory, to create molds from 3D printed parts. In reality these glossy, acetone smoothed parts just look better and give you a better idea what the finished product — injection-molded or milled — will look like when all is said and done.
