Continuous Liquid Interface Production

from Wikipedia, the free encyclopedia

The CLIP method ( English Continuous Liquid Interface Production ) is a proprietary 3D printing methods, the photopolymerization is used to smooth, hard objects from synthetic resin manufacture in a variety of forms. It was invented by Joseph DeSimone , Alexander and Nikita Ermoshkin and Edwad T. Samulski and was originally licensed from EiPi Systems. It is being further developed today (2018) by the Carbon company.

Procedure

The CLIP process uses ultraviolet light to cure a photosensitive resin while the article being manufactured is pulled up out of the resin bath

The continuous process begins in a container filled with photosensitive synthetic resin. The bottom of the container is partially transparent to ultraviolet (UV) light. A UV light beam is directed through the bottom to the resin, and precisely the area focused in which the resin is cured. The object to be printed is pulled out of the resin by a platform so slowly that the liquid resin can flow into the container. The bottom of the object and the container are always covered with liquid resin, which can be further hardened by the UV radiation. An oxygen- permeable membrane is placed under the resin, creating a dead zone (a transition phase that remains fluid) that prevents the resin from settling and polymerizing at the bottom of the reservoir.

In contrast to stereolithography , the printing process is continuous. For the process, the inventors claim that the printing time is up to 100 times shorter than with other 3D printing methods. The increase in speed arises from the fact that a moving UV focus is not used, but that the entire floor area is irradiated at the same time, similar to a film projection.

history

The CLIP process is described in two patents and was an acronym for Continuous Liquid Interphase Printing at the time the original patent was filed. An article detailing the developers' research was published in Science journal . At a TED talk in March 2015, DeSimone presented the prototype of a 3D printer that could use the CLIP process to print a comparatively complex object in less than ten minutes. DeSimone cited a scene from Terminator 2 - Day of Reckoning as inspiration for the CLIP technique , in which a robot from the future (the "T-1000"), made of a liquid metal alloy, is able to change its shape .
