ABSTRACT:
The present invention is a method which customizes the penetration depth of a heat-fusible powder used in solid freeform fabrication process such as laser sintering. The penetration depth of the heat-fusible powder is customized by combining opaque and transparent powders at a ratio which ensures that the beam contacts a portion of powder beneath its surface, thereby promoting complete layer sintering as well as adherence to previously sintered layers.
