ASTM WK73340
New Test Method for Additive Manufacturing -- Dynamic Properties -- Polymer Additive Manufacturing
1. Scope
To amend current dynamic property tests governed by D20 (D7791, D2927, and D5961) and D30 in order to offer up alternative geometries that can be used on polymer AM methods.Keywords
Non-metallic additive manufacturing (AM); polymer additive manufacturing (AM); material extrusion (ME); allowables; mechanical properties; thermoplastic manufacturing; AM characterization; standard deviation; tension-tension; uniaxial; fatigue; creep; dynamic; bearing fatigue::Rationale
The amended specification will be used to enhance current standards used for dynamic property characterization of polymer AM materials to account for process specific tendencies. The expected outcome is to drive appropriate failure mechanisms on easier to print specimens. Users can consist of machine operators, printer OEMs, testing houses, ASTM sub-committee members, technology adopters/type-certification holders, and certification regulators.
