Provided herein are methods for making 3D printed parts by additive manufacturing using post processing cleaners.

CLEANING PARTS

In an example implementation, a method of cleaning parts includes placing the parts into a variable compression chamber, filling the chamber with a liquid, and forcing pressurized gas to dissolve into the liquid to form a gas-liquid solution. The method includes cycling the pressure within the chamber around a gas solubility pressure level to repeatedly bring gas molecules out of the solution as gas bubbles, and force the gas molecules to dissolve back into the solution.
