Abstract
A subject-matter of the invention is the use of a polyamide powder possessing a fireproofing property in a process for the manufacture of an object made of polyamide by sintering this powder using radiation, the said powder comprising, by weight, 2 to 40% of at least one flame retardant for respectively 98 to 60% of at least one polyamide, the flame retardant being a blend of at least one organic phosphinate of a metal and of at least ammonium polyphosphate.
