The invention relates to a sinterable polymer composition, comprising: a random copolymer of propylene and an olefinic comonomer, containing about 2 to 10 wt % olefinic comonomer content, relative to 100 wt % of the random copolymer. The sinterable polymer composition may also contain at least one of a clarifier and a nucleator, and/or at least one additive selected from the group consisting of a primary antioxidant, a secondary antioxidant, an acid scavenger, a peroxide, an enhanced IR energy absorber, a long-term heat agent, and a polyolefin elastomer. The sinterable polymer composition has a melt flow rate from about 1 to 150 g/10 min (230° C./2.16 kg), measured according to ASTM D 1238; a crystallization temperature, Tc, from about 105 to 150° C.; and a xylene solubles content, XS, from about 3% to 40%.
