PA11 (SLS, EOS PA 1102 Black, dry as moulded)

EOS PA 1102 Black is a black-pigmented PA11 powder grade for selective laser sintering, described here in the dry state. Parts build in a heated powder bed that supports them, so no support structures are needed. They come out slightly porous with a matte, grainy surface, usually cleaned by blasting. As with other laser-sintered polyamides, strength and elongation are lower in the build direction than in the build plane. Compared with laser-sintered PA12, the PA11 base gives more ductile, impact-resistant parts, suited to snap fits, living hinges, clips, ducts and housings, where the through colour avoids dyeing. Every value on this page is read from EOS's own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
