The past few decades have seen substantial growth in Additive Manufacturing (AM) technologies. However, this growth has mainly been process-driven. The evolution of engineering design to take advantage of the possibilities afforded by AM and to manage the constraints associated with the technology has lagged behind. This paper presents the major opportunities, constraints, and economic considerations for Design for Additive Manufacturing. It explores issues related to design and redesign for direct and indirect AM production. It also highlights key industrial applications, outlines future challenges, and identifies promising directions for research and the exploitation of AM's full potential in industry.Design, Manufacturing, Additive Manufacturing

“…To date DfAM has mainly been focussed in two main areas -firstly, defining the design freedoms and customisation capabilities of AM (Gibson, Rosen, and Stucker 2010;Hague, Mansour, and Saleh 2004;Rosen 2014), and secondly investigating the optimal manufacturing strategy for additive manufactured parts (Adam and Zimmer 2014;Kerbrat, Mognol, and Hascoët 2011;Ponche et al 2014). Laverne et al (2015) classify these two DFAM research areas as 'design making' and 'design assessment', and further subdivide design making approaches into opportunistic DFAM methods which help designers explore creative shape complexity offered by AM, restrictive DFAM methods that take into account the limitations of AM and dual DFAM methods which combine the other two approaches.…”

Filomeno (2017). Design for Wire + Arc Additive Manufacture: design rules and build orientation selection. Journal of Engineering Design, 28(7-9) pp. 568-598.For guidance on citations see FAQs. ABSTRACTWire + Arc Additive Manufacture (WAAM) is an additive manufacturing technology that can produce near net-shape parts layer by layer in an automated manner using welding technology controlled by a robot or CNC machine. WAAM has been shown to produce parts with good structural integrity in a range of materials including titanium, steel and aluminium and has the potential to produce high value structural parts at lower cost with much less waste material and shorter lead times that conventional manufacturing processes.This paper provides an initial set of design rules for WAAM and presents a methodology for build orientation selection for WAAM parts. The paper begins with a comparison between the design requirements and capabilities of WAAM and other additive manufacturing technologies, design guidelines for WAAM are then presented based on experimental work. A methodology to select the most appropriate build orientation for WAAM parts is then presented using a multi attribute decision matrix approach to compare different design alternatives. Two aerospace case study parts are provided to illustrate the methodology. ARTICLE HISTORY

“…Both studies focussed on splitting a geometric part into smaller volumes, for which the optimal manufacturing sequence was identified. Kerbrat et al [19,20] presented a methodology to analyse the manufacturing complexity of a design for an additive and subtractive hybrid manufacturing system. Their approach represented a 3D geometric part through the division of space into small cuboid cells.…”

This paper presents a methodology for the transformation of a product concept into a detailed design and manufacturing process chain for hybrid manufacturing platforms. Hybrid platforms offer new capabilities and opportunities for product design. However, they require high levels of process expertise for effective design and effective process selection. Design for hybrid manufacture is challenging as there is a requirement to understand a number of technologies, which may be highly varied. To address this challenge, a knowledgebased decision-support system developed in this paper enables manufacturing expertise to be integrated into procedures for product design and process chain selection. This formalised numerical methodology is able to consider a wider range of varied manufacturing processes than any previous study. A feature-based design method is developed, which guides the designer towards an optimised product design during the embodiment design phase, and a process-chain selection program is utilised to enable the effective analysis of a product design based on product evaluation criteria. The methodology has been successfully applied to the design of an LED product with internal geometries and electronics.A decision-support methodology for embodiment design and process chain selection for hybrid manufacturing platforms 2 Key words:Design for manufacture, process chain selection, hybrid manufacture, feature-based design, decisionsupport.
