Method and device of layerwise manufacturing a three-dimensional object of a powdery material |
| abstract |
A polyamide powder is disclosed for use in a method of manufacturing a three-dimensional object by selectively solidifying layers of the polyamide powder at the locations corresponding to the cross-section of the object in the respective layer by application of electromagnetic radiation. The polyamide powder of the invention is reclaimed after manufacturing of an object and, then is treated with water or water vapor and subsequently dried. After treatment, the powder preferably can have a molar weight Mn (numeric average) of more than about 20,000 g/mol and a Mw (weight average) of more than about 40,000 g/mol. Also, the powder preferably has an excess of carboxylic end groups relative to amino end groups of at least 4:1 up to at most 200:1. |
