LASER SINTERING POWDER LASER SINTERING ARTICLE AND A METHOD OF MAKING A LASER SINTERING ARTICLE

摘要

The present invention relates to a hydrogenated styrene-butadiene / styrene-styrene (S (EB / S) S) block copolymer or a hydrogenated styrene-butadiene-styrene (SEBS) block copolymer or mixture thereof in an amount greater than 30 wt% to 90 wt%; Less than 10 wt% to less than 70 wt% of a C ₃ -C ₈ polyolefin or a mixture of two or more polyolefins; 0 to 20 wt% mineral oil, 0.2 to 1 wt% of at least one antioxidant, 0 to 5 wt% of a colorant, and 0 to 20 wt% of a surface modifier, wherein the total sum of the components is 100 wt% , And optionally 0 to 5 parts by weight of a powder fluidizing agent based on 100 parts by weight of the laser-sintered powder composition. The melt flow rate of this composition is at least 20 g / 10 min as measured at 190 占 폚 / 2.16 kg mass. The present invention also includes a laser-sintered article and a method of producing the same.
