brim
To promote adhesion of the ob ject being printed, some-
times an extra ring of material may be printed encircling
the object; this is referred to as a “brim”.
build plate
For 3D printers in general, the build plate is the platform
on which objects are printed. For the Pola r 3D p r i nter, the
build plate is a round mirror with a toothed gear on the
underside, that meshes with a gear on the build plate shut-
tle. 1, 4, 208, 213, 218, 230, 233, 235, 239, 246, See also
build plate shuttle
build plate shuttle
For the Polar3D printer, the build plate shuttle consists of
the carriage underneath the build plate: the shuttle arms
and pads, and the gear, on wh i ch the build plate rests. The
build plate shuttle slides along two support rods (in the x
axis of movement) and rotates (the ✓ polar coordinate) the
build pl a t e via its gear. See Fi gu r e B.1. 4, 5, 181, 182, 212,
231, 236, 247, See also build plate & polar coordinates
CAD
Computer Aided Design is the use of com p u t er systems to
aid in design. CAD output is often in the form of elect r o n i c
files; for 3D printing, the industry de- fa ct o standard is .stl
files. 47, 49, 84, 196, See also .stl file
