Standards Development

Scope

This document specifies design recommendations for the production of single-alloy metal parts using a Binder Jetting Technology, a Multi-Step Additive Manufacturing Process (BJT-MSt/M). The process category is binder jetting (BJT), a multi-step process (-MSt), for metallic materials (/M). As such, this document is extending the scope of ISO/ASTM 52910 for this technology in particular. The main characteristics of the process are also discussed.

Some of the fundamental design principles are also applicable to other AM processes, provided that due consideration is given to process-specific features.

This document also provides a review of the state of the art of design guidelines associated with the use of BJT-MSt/M by bringing together relevant knowledge about this process.

Purpose

Binder jet additive manufacturing of metals (BJT-MSt/M) is an additive manufacturing (AM) process that offers additional manufacturing options alongside other established AM processes. BJT-MSt/M has the potential to reduce manufacturing time and costs, and increase part functionality. Practitioners are aware of the strengths and weaknesses of conventional, long-established manufacturing processes, such as cutting, joining and shaping processes (e.g. by machining, welding, casting or metal injection moulding), and of giving them appropriate consideration at the design stage and when selecting the manufacturing process. In the case of BJT-MSt/M and AM in general, design and manufacturing engineers only have a limited pool of experience. Without the limitations associated with conventional processes, the use of BJT-MSt/M offers designers and manufacturers a high degree of freedom and this requires an understanding about the possibilities and limitations of the process.
