3D Systems, Inc.
Green part
A stereolithographic part prior to UV post-curing, but after Laser curing in the material 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.
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.
Linewidth
The horizontal width of a Laser cured material line.
Monomer
A low molecular weight chemical species, which is a printing block of polymers.
MSDS
Material Safety Data Sheet. Federal government mandated information about the chemical makeup of any chemical substance,
such as material. 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.
Platform
The perforated base on which parts are printed by the ProX 950.
Platform locators
Features that secure and position the edges of the platform.
Platform supports
L-shaped brackets that support the platform and attach it to the elevator.
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.
