Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a three dimensional object, which can be carried out with a simple, hence inexpensive and hard to fail, equipment. SOLUTION: The method for manufacturing the three dimensional object comprises the step of applying a susceptor on a region of a layer comprising a powdery substrate not absorbing or poorly absorbing a microwave radiation, where the layer is to be welded. The susceptor can absorb the microwave radiation, and discharges the absorbed energy to the surrounding substrate as a heat. Thereby, the substrate of the layer in the region, or occasionally of the layer above or below thereof, is welded by melting or sintering so that the three dimensional object is manufactured from the powdery substrate using the microwave radiation.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a molded member under the condensation of a polyamide molding material whose polyamide component contains phosphorus in an amount of at least 5 ppm limited by the production in the form of an acidic compound, with a compound having at least two carbonate units. SOLUTION: This method for producing the molded member is characterized by (a) adding a weak acid salt in an amount of 0.001 to 10 mass% based on the polyamide to the polyamide molding material, before or when compounded, (b) producing a mixture of the completed compound with a compound having at least two carbonate units, (c), if necessary, storing and/or transporting the mixture, and (d) then processing the mixture into the molded member, wherein a condensation is carried out for the first time in the process. According to the present invention, a middle processing pressure, a slight motor load, and the remarkable increase of melt stiffness are caused to considerably simplify the production of a hollow article or hollow deformed article having a large diameter.
