Elevator
The hardware components that raise and lower the platform and part in the vertical (Z) axis. Also
called Z-stage.
Exposure
The total light energy absorbed by a point on the resin surface. Exposure increases with higher
laser power and decreases with higher drawing speed.
Fill vectors (skin fill)
Overlapping parallel vectors that comprise the horizontal surfaces (skins) of stereolithographic
parts.
Green part
A stereolithographic part prior to UV post-curing, but after laser curing in the resin delivery module.
Hatch
A vector that is drawn between layer borders and comprises the interior of the part.
Hatch spacing
A parameter that specifies the perpendicular distance between adjacent hatch vectors.
IPM (Image Projection Module)
Directs the laser beam using directional, focusing optics, and scanning mirrors, along with an AOM
(Acoustical Optical Modulator) to regulate the output power. This process will accurately reproduce
the input CAD data one layer at a time.
