New Guide for Additive Manufacturing Design - Decision Guide

1. Scope

This work item proposal proposes a new task in the ISO/ASTM joint group JG54 on a guide to aid the selection of and design for AM processes, for a given application. Building on the more general ISO/ASTM 52910, Additive Manufacturing - Design - Requirements, guidelines recommendations, this guide would provide a reference document for someone considering AM for their product and would offer a way to identify a preferred subset of AM processes to explore further, without missing the opportunity to use a process they hadnt considered and without spending time examining unsuitable processes. To this end, it is proposed that the guide should assist in answering the questions: Can I use AM for this product, assembly or system Is AM a sensible choice Is the design suitable for the process


AM; additive manufacturing


A typical user of the guide might be someone who: Has an existing product already being manufactured conventionally and wants to know whether using AM instead is a feasible solution. Or, Has an idea for a product that cant be manufactured conventionally and is wondering if AM is an option. The guide should therefore provide a methodology for evaluating a products suitability for AM by considering (and referencing standards that cover) the following areas: Comparison of available AM processes and material groups An indication of achievable material properties and part sizes Types of features achievable by the process Other factors that could influence process selection e.g. oan outline of cost factors opost-processing needed oinspection methods Reference to AM-enabled business models which could affect design (legacy parts, mass-customisation, custom fit, RDM, etc) Examples of products adapted to AM what was changed (form, material), benefits derived Examples of non-suitable products and why The guide should contain sufficient information or guidance such that the reader either: Understands why AM is not feasible (at present), or Sees that AM might provide a solution and has some ideas for potential AM methods and where to look for further information, e.g. design guides for specific processes. The following are expected to be out of scope: Reference to specific AM equipment Information on software tools for AM design (eg geometry modelling, build preparation) Explanation of the digital workflow Specific cost models for processes or processes families. Details of specific materials and achievable properties. Description or reference to specific design tools Design guidelines for specific processes AM design best practice
