Most liquid-based additive manufacturing systems build parts in a vat of photo-curable liquid resin, an organic resin that cures or solidifies under the effect of exposure to light, usually in the UV range. The light cures the resin near the surface, forming a thin hardened layer. Once the complete layer of the part is formed, it is lowered by an elevation control system to allow the next layer of resin to be coated and similarly formed over it. This continues until the entire part is completed. The vat can then be drained and the part removed for further processing, if necessary. There are variations to this technique by the various vendors and they are dependent on the type of light or laser, method of scanning or exposure, type of liquid resin, and type of elevation and optical system used. Different technologies have been developed based on liquid AM by changing its sub-systems, those commercially available tech parts are discussed in this module. Moreover, a deep insight has been made in water based rapid freezing technology and its working conditions.
