Document Type and Number:
Japanese Patent JP4791688
Kind Code:
B2
Abstract:
A method for preparation of a 3-dimensional object including preparation of a layer of powder material, selective application of a bonding restraint (BR) to a selective region of this layer selected according to the cross-section of the object, repetition of these steps to form a matrix, where the outer limits of the object are formed via the boundary between the powder material with the applied BR and the untreated powder material is new. A method for preparation of a 3-dimensional object including:(a) preparation of a layer of powder material, (b) selective application of a bonding restraint to a selective region of layer (a), selected according to the cross-section of the object so that the bonding restraint is applied only on the region which does not comprise the cross-section of the object, (c) repetition of steps (a) and (b) until all cross-section surfaces of the object are present in a matrix and the outer limits of the object are formed via the boundary between the powder material with the applied bonding restraint and the untreated powder material, and (d) a least one treatment of the layers so that the parts without a bonding restraint are mutually bonded together is new. Independent claims are included for: (1) a shaped body prepared as above; (2) a powder material of particle size 10-200 micron and at least one polymer or copolymer selected from:polyester-, acetal-, propylene- , ethylene-, styrene-, carbonate,-, PMMA-, PMMI-, ionomer, polyamides, copolyester, copolyamides, terpolymer, or ABS, or a mixture of these; (3) a wettable BR containing water and surfactant.
