Cobra Aero is currently leveraging Renishaw’s metal additive manufacturing to optimise its design processes for aircraft and motorcycle engines.

The engine manufacturing company first collaborated with Renishaw to develop and gain expertise in its manufacturing processes and thereafter invested in the AM 400 system of the engineering technologies company.

In order to gain this expertise, the company improved the design of a cylinder for an unmanned aerial vehicle (UAV). The learning and discovery sessions happened at Renishaw Additive Manufacturing Solutions Centre in the USA. As a reminder, last year the company opened a new AM centre in California and its systems can be utilized in about 36 countries across the world.

Cobra Aero was therefore able to design a lattice structure to increase airflow and to produce one solid, lightweight part.

 “Staying at the cutting edge of manufacturing is important to Cobra Aero,” explained Sean Hilbert, President of Cobra Aero. “Investing in AM allows us to develop tools and new products for high value, small volume applications, speed up the manufacturing process and produce designs that would not be possible using conventional subtractive machining.”

We decided to redesign the cylinder because of its importance in an engine,” continued Hilbert. “Design changes to this part of the engine must happen rapidly and it is also a high value part, which is why we have chosen to additively manufacture this component. Improving the performance of the cylinder will also improve the overall performance of the engine.

Passionate about new technologies, I discovered 3D printing through different professional experiences. Aware of the importance of this technology for today's and tomorrow's markets, it is with great pleasure that I share the latest news and analysis related to it, so that you in turn, can take advantage of it. #Staytuned #3DAdept
