Raft
A platform adhesion option in which several layers of printed material are
deposited on the build surface to smooth out any irregularities in the build
surface and help prevent warping in the model being printed on top of the raft. A
raft also helps with bed adhesion of delicate models.
RepRap
An open source 3D printing project, started in 2005, to create the best desktop
printers and to make them capable of duplicating themselves.
Repetier Host
An open source slicer program, used for the preparation of STL files prior to 3D
printing. Allows manipulation of files prior to printing; rotating, scaling, and
duplication.
Resolution
The smallest movement a printer’s extruder can make within a single X-Y layer.
Often indicates the produced quality of a printed model.
Retraction
Backwards movement of an extruder motor to reduce the amount of material
stringing or oozing.
SD Card
A non-volatile memory card for use in portable devices to transfer information,
such as .gcode to 3D printers.
Seam
The point at which two layers of 3D-printed material connect.
Shell
The sidewalls of a 3D printed model, created by the exterior edges of every layer.
