Term Meaning
Backlight Unit A set of 405 nm LEDs emit light upwards through lenses, the
Light Processing Unit, and the bottom of the resin tank to cure
liquid resin.
Bite valve A flexible, rubber seal that regulates resin dispensing. Resin
flows out when the cartridge dispense arm squeezes the bite
valve open.
Build platform–see also, platform
lock
The aluminum base provides a surface for prints to attach to. Over
time, the build platform develops scratches from part removal,
which can assist with print adherence.

Build platform jig Stabilize the build platform for the secure removal of prints.
Secure the build platform jig to the edge of your work surface by
tightening the jig screw clamps underneath the work surface.
