Abstract:
The invention relates to a solar thermal collector absorber comprising channels each having a first end and a second end, the first ends of the channels opening into a first end chamber and the second ends of the channels opening into a second end chamber. According to the invention, the absorber is formed by a single part extruded from a solid nanocomposite material including a polymer matrix in which nano-objects and/or nano-structures are incorporated. The invention also relates to a solar thermal collector comprising one such absorber and a cover transparent to solar radiation on the absorber. The invention further relates to a method for producing said absorber.
Abstract:
A system for printing a three-dimensional object is provided. The system can include at least one print head configured to receive a continuous fiber and at least partially encase the continuous fiber with a formation material to create a composite material. The at least one print bed can be configured to move in at least six different degrees of freedom. The system can also include at least one print bed comprising a printing surface onto which the composite material may be selectively applied to form a work piece. The at least one print head can be positioned relative to the at least one print bed and configured to advance print media thereon.
Abstract:
An article (101) and a method (100) of forming an article are provided. The article includes a thermoplastic build material (103) and a polymeric support material (111). The polymeric support material is selectively removable from the thermoplastic build material through immersion in a solvent. The method of forming an article includes forming a part through additive manufacturing with a thermoplastic build material and a polymeric support material, immersing the part in a solvent, selectively softening the polymeric support material with the solvent, removing the part from the solvent, and separating the polymeric support material from the thermoplastic build material. Another method of forming an article includes forming a part through additive manufacturing with a thermoplastic build material and a polymeric support material, immersing the part in a solvent, selectively dissolving the polymeric support material with the solvent, and removing the thermoplastic build material from the solvent.
