摘要： The invention relates to a method for producing a three-dimensional object by selectively compacting layers of a powdery material (3a) in the areas corresponding to the cross-section of the object (3) in the respective layer, by applying electromagnetic radiation (7a). The powder used is a plastic powder, preferably polyamide. After the production of the object, the non-compacted powder (3a') is subjected to a water or vapour treatment at a higher temperature, is subsequently dried and then is used again to produce a new object.

摘要： The invention relates to a method for producing a three-dimensional object (2) by applying construction material (15) in layers and selectively solidifying same, having the step of applying a layer of the construction material (15) onto a construction base (10, 11, 12) within a construction field (8) and the step of selectively solidifying the applied layer by solidifying a region of the applied layer, said region corresponding to the cross-section of the object (2) in the layer, in order to produce a solidified region in the layer. The application and selective solidification steps are repeated until the three-dimensional object (2) is completed. A sub-region which is only one pre-determined part of the solidified region is post-treated at least once during the production of the three-dimensional object (2). The sub-region lies substantially in the interior of the solidified region.

摘要： The invention is about a composition comprising at least one polymer, wherein the polymer is in the form of a powder, and wherein the polymer comprises at least one thermoplastic polymer, wherein the thermoplastic polymer is selected from at least one polyaryletherketone and/or a copolymer and/or a block-copolymer and/or a polymer blend thereof, wherein the composition has a melt volume rate (MVR) of at least 5 cm 3 /10 min and a process of manufacturing and a use thereof. The invention also deals with a process for the manufacture of a construction element and the construction element thereof.
