Frequently asked questions

Is 90A easier to print than 85A?
Yes. 90A tolerates 30–50 mm/s and light retraction on direct-drive printers while still feeling clearly rubbery.
What does 90A mean?
Shore A hardness. 90A sits between a shoe sole (85A) and a shopping-cart wheel (95A).
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.
