Layer Height
Utmost determinant of quality for 3D printing, it defines the distance between
lines of extruded plastic in the Z-direction. Material extrusion 3D printers
typically print layers between 0.1mm and 0.3mm high. A lower layer height
translates to a smoother, higher quality print. A higher layer height translates
into a faster, low quality print.
Limit Switch
Mechanical switch that indicates where the “home” or “zero” position is on each
print axis.

Endstop
Material Extrusion
A 3D printing process that dispenses material through a nozzle or orifice. Also
known as FFF or FDM.

FDM, FFF
Minimal Layer Time
The least amount of time required of the printer to maintain action on any layer
of a printed object for the filament to sufficiently cool before fusing a layer on
top if it.
Mesh
A collection of polygons attached by edges and vertices that makes up a net-like
surface area in CAD.
Motor
In 3D printing, the stepper motor that produces precise movement of the
extruder, X-, Y-, or Z-axis.

Stepper
Nozzle
A brass or steel funnel-shaped die through which melted plastic is extruded.

OBJ
OBJ stands for Object File, an alternative to the STL file format. OBJ (.obj) files
store object exterior pattern and color.
