EOS PA 2200
PA12PowderSLSEOS
Quick answer
EOS PA 2200 is the reference PA12 powder for selective laser sintering: a balanced, unfilled nylon 12 with 48 MPa tensile strength (XY), 1650 MPa tensile modulus and 18% elongation at break in the XY plane, per the current EOS material data sheet.
PA 2200 is EOS's standard polyamide 12 powder and, in EOS's own words, has a "very balanced property profile". It is the grade most SLS users start with and the one against which other PA12 powders are compared: stiffness, strength and elongation are evenly matched, and it suits both prototypes and end-use parts.
Orientation matters. EOS publishes direction-dependent values: tensile strength is 48 MPa in X and Y but 42 MPa in Z, and strain at break drops from 18% in-plane to 4% in Z, because layer interfaces are the weak direction. Designers of loaded parts should read the XY figures as best-case and the Z figures as the design limit for cross-layer loads.

Processing notes
- SLS powder, processed on EOS polymer systems with the parameter set referenced in the data sheet (the published values correspond to the Balance parameter set at 120 µm layer thickness).
- Parts come out white; the material is widely used with dyeing and other standard SLS post-processing.
- EOS lists elongation as "strain at break" (ISO 527-1/-2); the figures in the table use that definition.
Typical applications
- Production equipment such as grippers, jigs and fixtures
- Medical surgery cutting guides and bone models
- Eyewear and consumer goods
- Automotive spare parts such as brackets and covers
- Functional prototypes with hinges or threads
Frequently asked questions
Is EOS PA 2200 the same as PA12?
PA 2200 is EOS's trade name for its unfilled PA12 (polyamide 12) SLS powder. Other manufacturers sell PA12 powders under their own names; properties differ slightly between brands because powder formulation and test setups differ.
How strong is PA 2200 in the Z direction?
EOS lists Z tensile strength at 42 MPa versus 48 MPa in X/Y, and Z strain at break at only 4% versus 18% in-plane. Cross-layer ductility is the main limitation to design around.
What is PA 2200 used for?
EOS lists grippers, jigs and fixtures, medical cutting guides and bone models, eyewear, automotive brackets and covers, and functional prototypes with hinges or threads — a general-purpose profile rather than a specialist one.
