Polymer powders for additive manufacturing (AM) must exhibit thermoplastic behavior so that they can be melted and re-melted to permit bonding of one layer to another. In this work, a methodology to select thermoplastics suitable for AM is described. As a case study, 21 thermoplastics intended to mechanical applications in nuclear power plants under mild environment (due to their moderated radiation resistance) are analysed using a stringency level methodology. The selected properties for the study have been the tensile strength (TS), elongation (EL), thermal expansion coefficient (α) and thermal conductivity (k)… See all…
