Frequently asked questions

Is 72D still flexible?
In thin sections, yes. In solid parts it behaves like a tough, slightly springy nylon with far better abrasion resistance than PLA or PETG.
Does 72D work in an AMS?
Yes. Shore D grades are hard enough for the AMS feed path, unlike 85A–98A.
Do I need to dry it before printing?
Every spool ships vacuum-sealed with desiccant. If the bag has been open for more than a few days, or you see popping and stringing, dry at the temperature on the spec grid before printing.
