4 Purpose
4.1 This document provides requirements, guidelines and recommendations for designing parts and products to be produced by AM processes. Conditions of the part or product that favour AM are highlighted. Similarly, conditions that favour conventional manufacturing processes are also highlighted. The main elements include the following:
— the opportunities and design freedoms that AM offers designers (Clause 5)
— the issues that designers should consider when designing parts for AM, which comprises the main content of these guidelines (Clause 6) and
— warnings to designers, or “red flag” issues, that indicate situations that often lead to problems in many AM systems (Clause 7).
4.2 The overall strategy of design for AM is illustrated in Figure 1. It is a representative process for designing mechanical parts for structural applications, where cost is the primary decision criterion. The designer could replace cost with quality, delivery time, or other decision criterion, if applicable. In addition to technical considerations related to functional, mechanical or process characteristics, the designer should also consider risks associated with the selection of AM processes.
4.3 The process for identifying general potential for fabrication by AM is illustrated in Figure 2. This is an expansion of the “identification of general AM potential” box on the left side of Figure 1. As illustrated, the main decision criteria focus on material availability, whether or not the part fits within a machine’s build volume, and the identification of at least one part characteristic (customization, lightweighting, complex geometry) for which AM is particularly well suited. These criteria are representative of many mechanical engineering applications for technical parts, but are not meant to be complete.
4.4 An expansion for the “AM process selection” box in Figure 1 is presented in Figure 3, illustrating that the choice of material is critical in identifying a suitable process or processes. If a suitable material and process combination can be identified, then consideration of other design requirements can proceed, including surface considerations and geometry, static physical and dynamic physical properties, among others. These figures are meant to be illustrative of typical practice for many types of mechanical parts, but should not be interpreted as prescribing necessary practice.AS ISO ASTM 52910 pdf download.
