Introduction

The test methods described in this document are used to evaluate the performance of an additive manufacturing system under given system settings and process parameters in combination with specific raw materials.

system performance.

This document is conducted by testing the minimum feature size, surface roughness and geometric accuracy of the test piece that can be formed by the additive manufacturing system.

Geometric performance evaluation.

Standard test pieces can be formed and measured directly when new equipment is installed.

Requirements for regularly evaluating the performance of an additive manufacturing system or diagnosing faults.

This document describes a standard test piece that can be used by both suppliers and buyers to evaluate the capabilities of an additively manufactured part or additive manufacturing system.

The test data described in this document can be used to measure the effect of new process parameters or materials on the performance of an AM system.

To assist in establishing performance traceability, specific test geometries can be built during each build process of the AM system.

Users can form specific standard test pieces individually according to their specific needs, without having to form all test pieces.
