摘要： 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.

摘要： The present invention relates to a system (100) for ventilating a defined space (102), such as for example an enclosed or at least partly enclosed basement, crawlspace or attic. The system (100) comprises a control unit (110) connected to at least one inside sensor (104), at least one outside sensor (106) and a controllable fan (108), the control unit (110) being configured to operate the controllable fan (102) if the absolute humidity (AHout) outside of the defined space (102) is lower or equal to the absolute humidity (AHin) within the defined space (102), and the temperature (Tin) within the defined space (102) is above a predetermined temperature when the temperature (Tin) outside of the defined space (102) is below the temperature (Tin) within the defined space (102). Advantages of the invention include energy efficient ventilation of the defined space and a high level of protecting from moisture related problems.
