Post Processing

Processes that render a created object usable (e.g. sanding, stair stepping, support structure removal, de-powdering, infiltration, painting).


Technique used to prevent warping in which a 3D-printed object is printed onto a “raft” of disposable material instead of directly on the bed.

Rapid Prototyping

RP, rapid prototyping, an additive processes of layering material to create a three-dimensional object; see 3D printing and additive manufacturing.


Material that is hard, strong, water-proof, transparent, and smooth, while allowing for a high level of detail.


Minimum feature size a process can be expected to reproduce which depends on pixels, laser spot size, mechanical precision, and layer thickness.


Method of creating objects from powders based on atomic diffusion that heats up particles until they bind together, used to join together separate pieces into a solid whole.


One layer of a 3D-printed object made up of many slices on top of one another, thickness varies from 0.001” to 0.10” depending on process used.


Process that converts 3D models into a format understood by 3D printers, slicing the model into layers that can be created by the extruder.


Selective laser melting, process that melts/fuses fine metallic powders together using 3D CAD data as a digital information source and energy in the form of a high-powered laser beam.


Selective laser sintering, additive manufacturing technology that uses photosensitive powders sintered by a laser to build an object layer by layer.

Stair Stepping

Creating a naturally stair-like look in the curved surface of a 3D-printed object because of the layer-by-layer additive method.


Process that uses photosensitive resins to trace cross-sectional geometry layer by layer, the technical name (coined in 1986 by Charles Hull) for what is now known as additive manufacturing, 3D printing, and rapid processes.


The standard file format for all rapid prototyping processes, also stands for stereolithography.
