Tessellate
To represent CAD surfaces in polygonal format.
Trapped Volume
During building, a volume of resin within the part that cannot flow out to the surrounding liquid.
Triangle normal
A line perpendicular to a triangle starting at its center and pointing away from the mass of the part.
Triangle normals are used to differentiate between inside and outside surfaces of a solid.
Ultraviolet (UV)
Electromagnetic radiation having a wavelength shorter than visible light, (i.e., below 390
nanometers).
Vat
On older SLA Centers, the metal container inside the process chamber in the SLA Center that holds
the resin in which the object is formed. On the iPro 8000/9000 SLA Center, this container is called
the RDM.
Vector
A directed line segment represented by starting and ending coordinates as defined in a
stereolithography slice or build file.
