Uniform thermal distribution imaging

A method of obtaining uniform thermal distribution imaging in a thermally initiated and thermally based laser sintering process whereby a three-dimensional object is formed layer-by-layer in which the scanning sequences in successive layers is varied to more uniformly control the build up of heat wi...

Beschreibung
Zusammenfassung:	A method of obtaining uniform thermal distribution imaging in a thermally initiated and thermally based laser sintering process whereby a three-dimensional object is formed layer-by-layer in which the scanning sequences in successive layers is varied to more uniformly control the build up of heat within a three-dimensional object being formed. An improved method of image scanning multiple parts in a single build process is also employed.
