PA11 (SLS, EOS PA 1101)

· PA 1101

EOS PA 1101 is an unfilled PA11 powder grade printed by selective laser sintering, in which a laser fuses successive layers of polyamide powder in a heated bed. The surrounding unfused powder supports the part, so no support structures are needed. Parts have slight porosity and a matte, grainy surface that is usually bead blasted and may be dyed or smoothed. Elongation and strength are lower across the layers than within them. Laser-sintered PA11 is more ductile and impact resistant than laser-sintered PA12, which suits it to functional prototypes and end-use parts such as snap fits, living hinges, clips and ducts. 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.

Quality & Standards

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
