Dynamic Interface Printing (DIP) is an advanced light-based 3D printing technique that uses a hollow print head with a transparent glass window to enable precise polymerization at the air–liquid meniscus. By submerging the print head into a liquid prepolymer solution, trapped air forms the meniscus, which acts as the print interface.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
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.
The term "Three-Dimensional Printing" was trademarked by the research group at MIT, along with the abbreviation 3DP. [5] [6] As a result, the term "3D printing" originally referred uniquely to the binder jet printing process prior to gaining wider acceptance as a term referring to all additive manufacturing processes.
Stereolithography (SLA or SL; also known as vat photopolymerisation, [1] optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and ...
Early construction 3D printing development and research have been under way since 1995. Two methods were invented, one by Joseph Pegna [9] which was focused on a sand/cement forming technique which utilized steam to selectively bond the material in layers or solid parts, though this technique was never demonstrated.
