2. 3D printing processes - Wikipedia

   en.wikipedia.org/wiki/3D_printing_processes

   Computer-Aided Design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.

3. Stereolithography - Wikipedia

   en.wikipedia.org/wiki/Stereolithography

   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 ...

4. Multi-material 3D printing - Wikipedia

   en.wikipedia.org/wiki/Multi-material_3D_printing

   An example of how 3D printing can be included in the design process is automotive design. [19] There, it is necessary to quickly test and verify a prototype to get the design approved for production. The reduced post-processing steps induced by the multi-material 3D printing technology result in a shorter fabrication time.

5. 3D printing - Wikipedia

   en.wikipedia.org/wiki/3D_printing

   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.

6. Continuous Liquid Interface Production - Wikipedia

   en.wikipedia.org/wiki/Continuous_Liquid...

   An oxygen-permeable membrane lies below the resin, which creates a “dead zone” (persistent liquid interface) preventing the resin from attaching to the window (photopolymerization is inhibited between the window and the polymerizer). [2] Unlike stereolithography, the printing process is continuous.

7. Photopolymer - Wikipedia

   en.wikipedia.org/wiki/Photopolymer

   A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. [1] These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light.
