One of the traditional manufacturing processes where material is injected under pressure into a cavity that is the shape of the desired part.
Abbreviation for metal powder bed fusion.
Refers to a CAD file that stores geometry in a format defined to a specific CAD system. A native file format may be proprietary or published. Opposite of a neutral file. Many CAD tools can now read native files from other vendors, and many additive manufacturing software tools can read the more common native files.
Packing multiple parts into the build volume of a machine to create the fastest and most efficient build or fitting as many parts as possible in the smallest build volume possible. Parts are often placed inside the cavities of other parts.
Refers to a CAD file that stores geometry in an agreed-upon and documented common format that most software tools that work with CAD geometry can read and write. The two most common neutral file formats are IGES, STEP. STL files are also considered a neutral file.
A manufacturing process where material is forced through a nozzle or die to create material in the shape of the nozzle or die.
A polygon, usually three-sided, the vertices of which sit on the desired surface of an object. STL files, the most commonly used way to define a part in additive manufacturing, use facets to define the part’s surfaces.
Part geometry defined with facets as opposed to spline surfaces.
Abbreviation for fused deposition modeling.
A collection of surfaces on an object or in the CAD representation of an object that define a recognized topology. As an example, a cylindrical hole, a pocket, a boss, a rib, or a keyway.
In FDM/FFF, the motor and gearbox that pushes the filament towards the nozzle.
Abbreviation for fused filament fabrication.
A long thread of material, cylindrical in cross-section. In additive manufacturing the filament is how the polymer material in FDM/FFF is delivered, usually on a spool or in a cartridge.
A physical part or assembly used in manufacturing to hold a part or check the shape of a part.
A type of material extrusion additive manufacturing where a continuous filament of thermoplastic material is fed into a heated extruder and deposited on the current build layer. It is the trademarked name used for systems manufactured by the process inventor, Stratasys. Fused filament fabrication is the generic term. Abbreviated as FDM
