This document establishes the required or the achievable classes of part properties for additive manufactured polymer parts in order to get a common understanding on part quality. It is aimed at providers of manufacturing services for polymer parts who use additive manufacturing machines and at the customers for these services. Designers of parts as well as buyers and providers of manufacturing services can specify, in a traceable manner, the required or the achievable level of part properties with the aid of this standard.

This document applies to parts that have been manufactured from a thermoplastic polymer by means of powder bed fusion with laser for polymers (PBF-LB/P), alternatively named laser sintering (LS) or material extrusion (MEX). Its applicability to other processes for polymers shall be checked in the specific case.

NOTE       Laser sintering is also known as selective laser sintering (SLS®).

NOTE       The process called material extrusion (MEX) in ISO/ASTM 52900 is also known as fused layer modelling (FLM), fused layer manufacturing or fused deposition modelling (FDM) or fused filament fabrication (FFF).

The classification of part properties apply to parts that have not been post-processed after unpacking from the build space and after removing possible support structures.

This document establishes specific parameters and recommendations for the qualification of polymeric materials intended for laser sintering. The parameters and recommendations presented in this document relate mainly to the material polyamide 12 (PA12), but references are also made to polyamide 11 (PA11). The parameters and recommendations set forth herein may not be applicable to other polymeric materials.
