Max Beswick required a high-quality custom boat impeller which boasted strength and rigidity for personal use. However, high costs from UK suppliers and long lead-times from overseas manufacturers meant finding the ideal partner was difficult. 3D printing was the only option to avoid using an expensive five axis CNC machine.
Mr Beswick required a suitable 3D printing process to achieve a strong and durable part without the high costs associated with UK suppliers.
CMG Technologies were able to work with Max to provide solutions to lower the costs while achieving the desired quality. Using Max’s own designs, we were able to manufacture a stainless steel solution to his previous PETG/nylon part which lacked strength.
CMG Technologies printed the impeller using CMG Tech-X 316L stainless steel filament on a 3DGence MP260x printer. Using a nozzle with a diameter of 0.5mm, geometrical precision was achieved with ease.
The part was printed with an 80% infill, therefore allowing a balance between costs, post-processing and performance. A combination of optimised printing parameters and post-processing allowed for cost-effectiveness without impacting the quality and strength of the part.
The impeller was manufactured for a water jet pump fitted to a two-metre boat, for personal use by Max.
After the quick turnaround of the part, Max installed the impeller to the pump ready to be fitted to the craft. He complimented the high-quality surface finish and denseness, noting the smooth finish with no evidence of a layered structure.
Max Beswick, Camera Technician within the film industry, said:
“CMG offer a very friendly service with expert help available straight away to help me in producing the best product for my needs.
“They offered me many solutions to suit my budget and once decided, I had my design printed, debound and sintered and then shipped to me all within a week. Highly recommend!”
Dr Samuel Wilberforce, Head of 3D Printing at CMG Technologies, said:
“We are extremely pleased we were able to provide Max with a high quality impeller while meeting his budget.
“The finished part shows how versatile 3D printing can be for various needs, and the kind words from Max is testament to the quality we pride ourselves on.”
