STLisshortforSTereoLithographyorStandard Triangulation Language.
Thislanguageviewsanyobjectasacollectionofsurfaces,anddescribeseach
surfaceoftheobjectasacollectionoftriangles.
Forexample,asquarecanbedescribedastwotriangles;acube(sixsquares)
as12triangles.Curvedsurfacesneedmoretrianglestodescribethem.The
higherthetolerance(forsmoothsurfaces),themoretrianglesareneeded.
Theresultisthathigh-qualityobjectdescriptionsmeanveryheavyfiles.
MostCADsoftwarecanexportSTLfiles.ObjetStudioopensthesefilesfor
printingmodelsontheObjet1000Plusprinter.
SLC Files
SLCisshortforStereo-Lithography Contour.SLCfilesdescribetwo-
dimensionalcontoursofthethree-dimensionalmodels.Thesecontourlines
arepolylines.
SLCfilesareASCII(text)filesthatsavemodelsasaseriesofslices.This
meansthatmodelsbasedonSLCfilescannotbeorientated;onlytheirscale
(size)andpositiononthebuildtraycanbecontrolled.Forthisreason,the
model’sorientationmustbesuitableforproductionbeforeitissavedasan
SLCfile.BecauseofthenatureofSLCfiles,theappearanceofmodelsinObjet
Studiomaybedifferentthanthesolid-objectimagesdisplayedfromSTLfiles.
