Rapid prototyping and simulation using WAAM

02 March 2023

Mention the words ‘prototype’ and ‘large-scale component’ in the same sentence and you would be forgiven for imagining extended lead times and significant cost implications. That might have been true in days gone by, but now, thanks to developments in metal additive manufacturing, it can be done in weeks and at significantly reduced costs.

Filomeno Martina, CEO and Co-Founder of WAAM3D, discusses how wire arc additive manufacturing (WAAM) has the potential to change the future of large-component prototype design in manufacturing, and showcases an aerospace prototype that has reduced material usage by 74 percent. 

Rapid metal-component prototyping 
As the name implies, ‘rapid’ prototyping should be fast, cost-effective and precise, and allow for more flexibility in the design process. The quick production of parts enables the demonstration of concepts, the testing of new products, and the refining of designs. 

When it comes to rapid prototyping of metal components, engineering product designers can choose between additive manufacturing (3D printing) or subtractive manufacturing. Both offer specific benefits, but for larger-scale metal prototype components, WAAM is making waves in its ability to deliver significant time, cost and flexibility benefits that are just not possible using subtractive manufacturing methods.
