What is EOS PA 1101?
EOS PA 1101 is EOS' PA11 powder for Selective Laser Sintering on EOS FORMIGA P 110 / P 396 / P 500 / P 770. EOS PA 1101 has a tensile strength of 50 MPa (7.25 ksi), stronger than 54% of polymer grades. Elongation at break is 30% and the elastic modulus is 1.65 GPa (0.239 Msi). EOS PA 1101 has a density of 1.03 g/cm³ (0.0372 lb/in³), lighter than 71% of polymer grades.

Choosing PA 1101
A natural PA11 SLS powder to consider for ductile parts exposed to flexing or impact.
- Consider it for
- Clips and buckles · Impact-prone covers and housings · Eyewear and other durable consumer components
- Tradeoffs
- The published heat-deflection temperature changes substantially with test load. Compare like-for-like load and conditioning before choosing it for a hot, loaded fixture.
- Design and validation
- For a living-hinge-like feature, prototype its radius, thickness and orientation rather than extrapolating from a tensile bar. Confirm conditioning and service humidity for critical fits.
- Finishing
- Natural, slightly translucent parts can be dyed. Dye changes appearance only after printing; sealing or coating still needs qualification where liquid exposure matters.
- Before choosing
- Will the part see repeated deflection or impact? Does the load case instead favor a rigid PA12-GF or CF-filled option?

What should I validate before using EOS PA 1101?
For a living-hinge-like feature, prototype its radius, thickness and orientation rather than extrapolating from a tensile bar. Confirm conditioning and service humidity for critical fits. Will the part see repeated deflection or impact? Does the load case instead favor a rigid PA12-GF or CF-filled option?
How can EOS PA 1101 be finished?
Natural, slightly translucent parts can be dyed. Dye changes appearance only after printing; sealing or coating still needs qualification where liquid exposure matters.
