Plastometrex pushes indentation testing as a coupon-free check for metal AM parts
Plastometrex says half its customers work in additive manufacturing and defence, using its indentation test to measure yield and tensile strength without printing test coupons. The method is now covered by ASTM E3499-25, which should ease the hesitation of conservative manufacturing engineers. Its CTO also reports property variation of 15 to almost 20 percent in metal AM parts, even when best practice is followed.
