| 20080258346 | COMPOSITE POWDER, USE IN A SHAPING PROCESS, AND MOULDINGS PRODUCED FROM THIS POWDER - The present invention relates to a composite powder of polymer powder and porous glass beads, and to the use of this composite powder for shaping processes, and also to mouldings produced from this composite powder. | 10-23-2008 |
| 20080300353 | LASER SINTER POWDER WITH METAL SOAPS, PROCESS FOR ITS PRODUCTION, AND MOLDINGS PRODUCED FROM THIS LASER SINTER POWDER - A sinter powder containing a polyamide and metal soaps, in particular particles of a salt of an alkanemonocarboxylic acid. A process for laser sintering, and to moldings produced from the sinter powder. The moldings formed using the powder have advantages in appearance and in surface finish when recyclability in the selective laser sintering (SLS) process is taken into account. Moldings produced from recycled sinter powder have improved mechanical properties, in particular in the modulus of elasticity and tensile strain at break. | 12-04-2008 |
| 20090088508 | POWDERY COMPOSITION OF A POLYMER AND A FLAMEPROOFING AGENT CONTAINING AMMONIUM POLYPHOSPHATE, METHOD FOR THE PRODUCTION THEREOF, AND MOULDED BODY PRODUCED FROM SAID POWDER - The present invention relates to a powder which, in addition to a polymer, comprises a flame retardant based on ammonium polyphosphate, to the use of this powder for the layer-by-layer production of moldings, and also to moldings produced from this powder. The moldings constructed using the inventive powder have marked advantages with regard to their flammability, when comparison is made with conventional products, and this permits use in aircraft, for example. | 04-02-2009 |
| 20090236775 | COPOLYAMIDE POWDER AND ITS PREPARATION, USE OF COPOLYAMIDE POWDER IN A SHAPING PROCESS AND MOULDINGS PRODUCED FROM THIS COPOLYAMIDE POWDER - A task often encountered in very recent times is the rapid provision of prototypes. Particularly suitable processes are those based on pulverulent materials and in which the desired structures are produced layer-by-layer through selective melting and solidification. The invention provides the constitution, production and use of a copolyamide powder which was produced using the following monomer units: a) laurolactam or ω-aminoundecanoic acid, and also b) dodecanedioic acid, and either c) decanediamine or dodecanediamine, in shaping processes, and also to mouldings produced through a layer-by-layer process which selectively melts regions of a powder layer, using this specific powder. Once the regions previously melted layer-by-layer have been cooled and solidified, the moulding can be removed from the powder bed. The mouldless layer-by-layer processes for the production of components using the copolyamide powder result in simplified and more reliable conduct of the process and better recyclability. | 09-24-2009 |
| 20100324190 | POWDERY COMPOSITION OF A POLYMER AND A FLAMEPROOFING AGENT CONTAINING AMMONIUM POLYPHOSPHATE, METHOD FOR THE PRODUCTION THEREOF, AND MOULDED BODY PRODUCED FROM SAID POWDER - A pulverulent composition that is a powder containing at least one polymer, and at least one flame retardant that contains ammonium polyphosphate, the powder having a maximum particle size of ≦150 μm and a median particle size of from 20 to 100 μm. | 12-23-2010 |
| 20110118410 | COMPOSITE POWDER, USE IN A SHAPING PROCESS, AND MOULDINGS PRODUCED FROM THIS POWDER - The present invention relates to a composite powder which comprises polymer powder and porous glass beads, and to the use of this composite powder for shaping processes, and also to mouldings produced from this composite powder. | 05-19-2011 |
| 20110130515 | POLYMER POWDER COMPRISING A COPOLYMER, USE IN A SHAPING METHOD WHICH USES A NON-FOCUSED APPLICATION OF ENERGY AND MOULDED BODY THAT IS PRODUCED FROM SAID POLYMER POWDER - A molding produced by a layer-by layer process of selectively melting regions of a respective pulverulent layer via unfocused introduction of electromagnetic energy, using a polymer powder, where the powder has at least one thermoplastic random copolymer with an ISO 1133 MFR value of from 12 to 1 g/10 min. | 06-02-2011 |
