ABS As Printed vs ABS GF40

Polymer · ABS grade comparison

ABS As Printed and ABS GF40 are two grades of the same polymer grade, ABS: As Printed (as built (as printed)) versus GF40 (40% Glass Fiber). The chemistry is identical, so every difference below comes from the condition. ABS GF40 is the stronger of the two: yield strength 42 MPa (6.09 ksi) against 29 MPa (4.21 ksi) for ABS As Printed, about 45% more; tensile strength follows at 110 MPa (16 ksi) vs 30 MPa (4.35 ksi). In exchange, ABS As Printed is the more ductile: elongation 6% versus 1.8% for ABS GF40. ABS As Printed is lighter (1.02 g/cm³ vs 1.36 g/cm³ for ABS GF40) and ABS GF40 is stiffer (11 GPa vs 1.9 GPa). On the shop floor, ABS As Printed machines more easily (very good vs fair) and ABS As Printed welds better (very good vs poor).
