Digital ABS vs PA6

Polymer · grade comparison

Digital ABS and PA6 are both polymer grades, both engineering plastic. PA6 is the stronger of the two: tensile strength 80 MPa (11.6 ksi) against 57 MPa (8.27 ksi) for Digital ABS, about 40% more. PA6 is the more ductile: elongation 60% versus 30% for Digital ABS, and Digital ABS is harder (86 Shore D vs 81 Shore D). PA6 is stiffer (3 GPa vs 2.8 GPa) and PA6 runs hotter in service (90°C vs 50°C continuous). On the shop floor, PA6 machines more easily (68 vs 55 out of 100), PA6 welds better (good vs poor), and PA6 sits in a lower cost tier (budget, $) than Digital ABS (specialty, $$$$$).

PA6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

Digital ABS vs PA6 — frequently asked

Is PA6 stronger than Digital ABS?

Yes. PA6 has a typical tensile strength of 80 MPa (11.6 ksi) against 57 MPa (8.27 ksi) for Digital ABS — about 40% more.

Which is cheaper, Digital ABS or PA6?

PA6 is the lower-cost material: it sits in the budget tier ($) while Digital ABS is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, Digital ABS or PA6?

PA6, by a small margin. Both rate good for machinability — 68/100 against 55/100 for Digital ABS; for welding the order is PA6 first (good, 62/100) then Digital ABS (poor, 15/100).
