Claim 0:
1. A sinter powder (SP) comprising the following components:
(A) at least one first polyamide component (PA1) comprising, based on the total weight of the first polyamide component (PA1), at least 50% by weight of a first aliphatic polyamide (aPA1), where the first polyamide component (PA1) has a first melting point (TM1) and where the first aliphatic polyamide (aPA1) has been formed from repeat units having a first ratio (V1) per repeat unit of CH2 groups to NHCO groups in the range from 4 to 6,
(B) at least one second polyamide component (PA2) comprising, based on the total weight of the second polyamide component (PA2), at least 50% by weight of a second aliphatic polyamide (aPA2), where the second polyamide component (PA2) has a second melting point (TM2) and where the second aliphatic polyamide (aPA2) has been formed from repeat units having a second ratio (V2) per repeat unit of CH2 groups to NHCO groups in the range from 4 to 6,
wherein the second melting point (TM2) is higher than the first melting point (TM1) and where the quotient (Q) of the numerical value of the second ratio (V2) divided by the numerical value of the first ratio (B1) is in the range of 0.6 to 1.5.
