Abstract
A sinter powder containing a polyamide and metal soaps, in particular particles of a salt of an alkanemonocarboxylic acid. A process for laser sintering, and to moldings produced from the sinter powder. The moldings formed using the powder have advantages in appearance and in surface finish when recyclability in the selective laser sintering (SLS) process is taken into account. Moldings produced from recycled sinter powder have improved mechanical properties, in particular in the modulus of elasticity and tensile strain at break.
Claims29
A sinter powder for selective laser sintering, comprising at least one polyamide and at least one metal soap selected from the group consisting of a salt of a fatty acid having at least 10 carbon atoms, a salt of montanic acid, or a salt of a dimer acid.
