METHOD FOR OBTAINING A THREE-DIMENSIONAL OBJECT USING POSSESSING ANTI-MICROBIAL PROPERTIES OF POWDER PLASTIC AND POSSESSING ANTI-MICROBIAL PROPERTIES OF POWDER PLASTIC FOR SUCH METHOD

摘要

1. A method of manufacturing a three-dimensional object by layer-by-layer sintering of powder building material in each layer of sections corresponding to the object under the influence of electromagnetic or particle radiation, where the synthetic powder used as building material has antimicrobial properties, in which! antimicrobial action is carried out by an antimicrobial additive, which is present in powder grains, and! the additive is present in the range of from about 0.05 to about 5% by weight, preferably from about 0.1 to about 2% by weight. ! 2. The method according to claim 1, characterized in that the additive is present in each particle of the powder of the building material. ! 3. The method according to any one of claims 1 to 2, characterized in that the synthetic powder contains a polymer, preferably polyamide. ! 4. The method according to any one of claims 1 to 2, characterized in that the synthetic powder contains polyamide 11 and / or polyamide 12.! 5. The method according to claim 3, characterized in that the synthetic powder contains polyamide 11 and / or polyamide 12.! 6. The method according to any one of claims 1, 2 or 5, characterized in that the additive contains a noble metal, for example silver. ! 7. The method according to claim 3, characterized in that the additive contains a noble metal, for example silver. ! 8. The method according to claim 4, characterized in that the additive contains a noble metal, for example silver. ! 9. The method according to claim 6, characterized in that the noble metal is present in metallic form or in the form of salt or ions. ! 10. The method according to any one of claims 7 or 8, characterized in that the noble metal is present in metallic form
