A 3D selfie in 1:20 scale printed by Shapeways using gypsum-based printing, created by Madurodam miniature park from 2D pictures taken at its Fantasitron photo booth. In the original implementations, starch and gypsum plaster fill the powder bed, the liquid "binder" being mostly water to activate the plaster.
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.
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.
CNC mills or routers include proprietary software which interprets 2D vector drawings or 3D models and converts this information to a G-code, which represents specific CNC functions in an alphanumeric format, which the CNC mill can interpret. The G-codes drive a machine tool, a powered mechanical device typically used to fabricate components. [4]
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.
The largest 3D printer or Additive Manufacturing machine utilizing cold spray can build parts up to 9×3×1.5 m. [7] During the cold spray process, the impacting particles create the layer, whose thickness can differ, based on the spray gun travel speed against the substrate and the feedstock material feed rate, building the structure layer-by ...
