Green part
A stereolithographic part which has been removed from the printer, prior to UV post-curing.
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.
Laser
Light Amplification by Stimulated Emission of Radiation. The device that generates the light energy required to polymerize
photocurable material.
Layer
Thin horizontal section of laser-solidified material.
Layer thickness
The depth of a solidified layer of material, as requested by the user.
Leveling
The process whereby the surface of the material is adjusted to the correct distance from the dynamic mirrors.
Line
A line of cured plastic generated by overlapping bullets. See also
vector.
Line width
The horizontal width of a Laser cured material line.
Monomer
A low molecular weight chemical species, which is a printing block of polymers.
MSDS/SDS
Material Safety Data Sheet / Safety Data Sheet. Federal government mandated information about the chemical makeup of
any chemical substance, such as photocurable resin. Usually includes identification of toxic substances and safe handling
guidelines.
NIOSH
National Institute for Occupational Safety and Health.
Photoinitiator
A chemical in photopolymers that reacts with photons and catalyzes the polymerization process.
Photopolymer
A chemical substance composed of photoinitiators and monomers that polymerizes when exposed to light energy.
Photopolymerization
The process whereby light energy converts monomers into a polymer.
Polymer
A material built up from a series of smaller units (monomers). The molecular size of the polymer helps to determine the
mechanical properties of the plastic material.
Polymerization
The process of linking small molecules (monomers) into larger molecules (polymers) comprised of many monomer units.
Post-Curing Apparatus (PCA) and ProCure equipment
A device which generates ultraviolet energy used to cure green stereolithographic parts.
Post-process
The process of cleaning, curing, and finishing stereolithographic parts.
