    摘要: In one embodiment, a tool for forming an article in a molding operation has a tool body formed from a non-particulate material, with a particulate material bonded to the body. The body provides a forming surface for forming the article. The particulate material, or the particulate material and the tool body collectively provide a duct for conveying a fluid for transfer of heat with the forming surface. In another embodiment, the tool has a tool body formed from a non-particulate material with a cavity and the particulate material is disposed within the cavity. A heat transfer material is disposed in the cavity bonding the particulate material to the tool body. Methods for manufacturing such tools are also disclosed.

    摘要: The present invention incorporates one or more diode lasers for the high-power CO2 or Nd-YAG lasers currently used in closed-loop DMD systems. Being semiconductor-based, such devices are almost instantaneously responsive to the electrical input. As such, a DMD system driven by a diode laser according to the invention provides a much faster response compared to other sources. The faster response time, in turn, provides for enhanced dimensional control and capability to produce intricate components with better dimensional accuracy.
