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.
Printhead
The assembly which contains the IPM and scanning mirrors.
Print Applicator
The assembly of a ProX 950 that either applies material to, or removes excess material from the part, as the applicator moves
across the material surface.
Print chamber
The chamber in which the MDM, elevator, and beam profilers are located.
Material Delivery Module (MDM)
The metal container inside the process chamber in the ProX 950 that holds the material from which the part is formed. On older
SLA Centers, the MDM is referred to as the vat.
Safety shutter
A mechanical device that blocks the Laser beam when an interlock switch is activated or when closed via the computer user
interface.

Sensitization
An allergic response to a chemical stimulus, such as material, generally resulting from repeated skin contact.

Stereolithography apparatus
The equipment used to produce stereolithographic parts.
Slice resolution
A slice parameter that specifies the number of slice units assigned to each CAD unit of measure.
Stereolithography
A three-dimensional imaging process that forms plastic objects by solidifying successive layers of photocurable material.
Stereolithography file (STL)
The tessellated (triangulated) CAD input file.
Supports
Structures designed on the CAD system or by Print3D Pro to support a part above the elevator platform, provide a rigid
foundation on which the object may be printed, and attach and support layer sections.
Sweep
A pass of the print applicator from the front of the material delivery module to the rear or from rear to front. The act of
removing excess material from the upper surface of the part or adding a layer of fresh material during the application process.
Tessellate
To represent CAD surfaces in polygonal format.
Trapped Volume
During printing, a volume of material within the part that cannot flow out to the surrounding liquid.
