Planning, preparing and producing: Walking the tightrope between additive and subtractive manufacturing

In the following article Delcam’s Kelvin Hamilton explores the current possibilities for design, topology optimisation, simulation, process planning and process preparation in metal Additive Manufacturing (AM). Exploring the three Ps, Plan, Prepare and Produce, all the processes involved in transforming three airbrake bracket designs into final products are revealed. As well as explaining how important it is to appreciate and plan for the significant amount of subtractive manufacturing in metal AM, a number of the lessons learnt in this project are discussed as the author reflects on the experience of planning, preparing and producing parts [First published in Metal AM Vol. 2 No. 1, Spring 2016] ...

Titanium powder pyrophoricity, passivation and handling for safe production and processing

As Additive Manufacturing moves out of the prototyping space and into production facilities with multiple machines, the importance of handling and processing powders, particularly titanium, becomes ever more relevant. In this article Dr Andrew Heidloff and Dr Joel Rieken, from Praxair Surface Technologies, Inc., review best practice when handling and storing titanium powders for AM. Titanium powder can be safely produced, processed, stored and shipped using appropriate precautions, however under certain conditions it can become quite hazardous. These hazards can be mitigated by following the suggested precautions reviewed below [First published in Metal AM Vol. 2 No. 1, Spring 2016] ... Read more »

Process and quality control for AM: Sigma Labs PrintRite3D® methodology for overall quality assurance

Despite the outstanding promise of metal Additive Manufacturing technologies, inconsistent quality, process reliability and speed are currently holding back industry growth and impacting on the cost-effectiveness of new applications. In the following article Sigma Labs’ Dr Vivek R Dave and Mark J Cola review the technical challenges that are faced in enabling metal AM to reach its full potential and the systems that are currently available to address a number of critical issues [First published in Metal AM Vol. 2 No. 1, Spring 2016] ...
