STL
The most popular file format for 3D printing, the format represents a 3D object by describing the surface as a series of triangles.
Filament
The base material that's used to 3D print objects via fused deposition modeling.
Extruder
The parts of a 3D printer that controls the of the filament.
Build plate
The surface on which 3D prints are made.
Resolution
The surface quality of a 3D print, typically defined by the layer
height.
Shells
Outside walls that make up the perimeter of your 3D object.
Infill
The support structure built in the interior of a 3D model. It's density can
be varied.
Supports
Removable scaffolding structure built to help parts of an object that
would otherwise be in midair with no material below.
Slicing
The process of converting a 3D model into a printable file.0
Print-in-place
A design with parts that can move immediately after printing.
G-code
The language used to instruct your 3D printer to perform operations. In common usage this is almost exclusively generated by software, and is not written by hand.
Computer Aided Design (CAD)
Software that enables users to create models in either two or three dimensional formats.
Polylactic Acid (PLA)
A hard, odorless bioplastic made from renewable, starch-based resources for 3D models and prototyping at home.
Acrylonitrile butadiene styrene (ABS)
A plastic well-known for its strength and industrial purposes that is impact resistant, very hard, whilst retaining good flexibility.
Additive Manufacturing
The process of building up a three-dimensional object, one thin layer at a time.
Functional Prototype
A near-final model or representation of a product, created during the design process to evaluate the form, fit and function of an object and its constituent parts.
Rapid Prototyping (RepRap)
Machines which are open-source 3D printers utilizing the fused filament fabrication process.
Fused Deposition Modeling (FDM)
A 3D printing process that extrudes heated thermoplastic material through a computer-controlled print-head nozzle to build parts up layers.
Selective Laser Sintering (SLS)
A technology commonly employed by 3D printing services for metallic objects with a powder bed fusion that uses a laser to selectively fuse — or sinter together granules of successive layers of powder.
Stereolithographic Apparatus (SLA)
A 3D printing technology that works via a process called vat photopolymerization with objects built in layers.
