Continuous Liquid Interface Production

Continuous Liquid Interface Production (CLIP; originally Continuous Liquid Interphase Printing) is a proprietary method of 3D printing that uses photo polymerization to create smooth-sided solid objects of a wide variety of shapes using resins.

It was invented by Joseph DeSimone, Alexander and Nikita Ermoshkin and Edward T. Samulski and was originally owned by EiPi Systems, but is now being developed by Carbon.

The inventors claim that it can create objects up to 100 times faster than commercial three dimensional (3D) printing methods.

[8] At a TED talk in March 2015, DeSimone demonstrated a 3D-printer prototype using CLIP technology and produced a relatively complex object in less than 10 minutes, 100 times faster than other 3D printing techniques.

[9] DeSimone cited a scene in the 1992 film Terminator 2: Judgment Day, where the T-1000 machine reforms itself from a metallic pool, as an inspiration for the technology's development.

The Continuous Liquid Interface Production method uses ultraviolet light to harden a photosensitive resin while the fabricated object is drawn up out of the resin bath.
