Trial resin

Trials can use standard resin if production grade is defined

Teams sometimes mold T1 in a general-purpose grade to save MOQ, then switch to a supplier-documented grade for production.

That is acceptable only with a controlled BOM revision and new validation when the grade changes.

Do not imply the molder certifies the part; certifications attach to supplier grades and your test plan.
