PA12 EOS PA 3200 GF vs PA12 Sinterit PA12 Smooth
Polymer · PA12 grade comparison
EOS PA 3200 GF and Sinterit PA12 Smooth are two grades of the same polymer grade, PA12: EOS PA 3200 GF versus Sinterit PA12 Smooth. The chemistry is identical, so every difference below comes from the condition. EOS PA 3200 GF is the stronger of the two: tensile strength 51 MPa (7.4 ksi) against 38.44 MPa (5.58 ksi) for Sinterit PA12 Smooth, about 33% more. EOS PA 3200 GF is the more ductile: elongation 9% versus 4.55% for Sinterit PA12 Smooth, and EOS PA 3200 GF is harder (80 Shore D vs 76 Shore D). Sinterit PA12 Smooth is lighter (0.95 g/cm³ vs 1.22 g/cm³ for EOS PA 3200 GF) and EOS PA 3200 GF is stiffer (3.2 GPa vs 1.572 GPa).
EOS PA 3200 GFChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Sinterit PA12 SmoothChoose it when weight is the constraint.
EOS PA 3200 GF vs Sinterit PA12 Smooth: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
