Rich in creativity and rooted in a long artisanal manufacturing heritage, one would imagine that there can be few sectors as perfectly suited to embrace the potential of metal Additive Manufacturing than the jewellery industry. In reality, however, the sector continues to hold back on the full-scale adoption of AM, despite numerous successes. In this article, Michela Ferraro-Cuda considers progress to date in the adoption of precious metal AM in the jewellery industry, and showcases a number of leading designers who have leveraged the technology’s potential for innovation and differentiation.

Able to achieve quicker build speeds and lower cost per part than its rival technologies, metal Binder Jetting (BJT) has generated increasing interest and rapid industry investment over the past two years. But while many engineers are now becoming familiar with the principles of design for Powder Bed Fusion AM, design for BJT is less widely understood. In this article, Olaf Diegel and Terry Wohlers attempt to demystify some of the key factors that must be considered when designing parts for BJT.

As the metal Additive Manufacturing industry matures at a rapid rate, organisations are now faced with the challenge of scaling their AM operations. Based on a study of 253 companies in a number of sectors, US-based AM software specialist Link3D has developed an ‘Additive Manufacturing Maturity Model’. This simple model can be used as a tool to understand an organisation’s AM maturity whilst also helping them navigate the steps to developing an agile and resilient AM supply chain. Shane Fox, CEO and co-founder of Link3D, explains. [First published in Metal AM Vol. 6 No. 2, Summer 2020]

Laser Beam Powder Bed Fusion (PBF-LB) is a technology rich in process parameters and exacting material specifications, all developed with the aim of delivery quality and repeatability as the industry moves towards volume production. However, without control of a laser’s focal spot, neither the material specification nor the handling of the material in the build chamber can guarantee the hoped-for results. As Ophir Spiricon Europe’s Christian Dini explains, when it comes to lasers, there is no control without the gathering of reliable data. [First published in Metal AM Vol. 6 No. 2, Summer 2020]

The wide potential of Additive Manufacturing in the oil and gas and maritime sector has come to be widely accepted, with the technology offering significant advantages in terms of lead time, part weight, part count, higher levels of geometric complexity and new material properties. However, in these safety-critical industries, there remain some concerns regarding the quality of AM parts. A Joint Industry Project (JIP), begun in January 2018 and consisting of twenty partners, aims to deliver a new JIP Guideline on Additive Manufacturing for this sector. Here, DNV-GL’s Harsharn Singh Tathgar and Berenschot’s Onno Ponfoort report on the guideline’s development. [First published in Metal AM Vol. 5 No. 3, Autumn 2019]
