Domin improves 3D printing with in-house powder extraction

Domin from the UK is a developer and manufacturer of advanced hydraulic systems. The company relies on additive manufacturing. The team relies on an in-house powder extraction system.

A key element of the additive manufacturing process used by Domin is the use of powders as a raw material. In this process, a focused laser is directed by a machine into a bed of metal powder, creating complex structures layer by layer. This method enables the production of complex components with remarkable precision and efficiency.

One challenge in additive manufacturing is the removal of excess powder from the printed parts, a process known as powder extraction. This step is crucial to ensure high quality standards and to collect the powder for reuse, which is also an important environmental benefit.

Domin faced the challenge of the powder being trapped in the small and difficult to access internal areas of their valve manifold. The development of an in-house powder extraction process was therefore necessary to avoid the health and safety risks of loose powder during heat treatment.

Domin’s production team initially looked for a solution on the market, but found no suitable, affordable options. Therefore, the company decided to develop and build its own machine that can extract powder from complicated internal structures. This machine was developed in just five months and removes the powder in just 10 minutes through constant vibration in two axes.

The benefits of Domin’s in-house powder extraction capability are significant. It enables clean, controlled powder cleaning, reduces the risk of powder exposure and reduces costs by eliminating waste. It also significantly improves the efficiency of the powder extraction process.

Domin is committed to continuing to develop advanced, in-house processes to continuously improve the way the company operates. The goal is to remain at the forefront of innovative hydraulic component design and manufacturing. This latest development underlines Domin’s commitment to innovation and pioneering work in the field of hydraulics.

In summary, Domin’s innovative approach to additive manufacturing and powder extraction represents a significant advance in the production of hydraulic components. By developing its own processes and technologies, the company can not only improve the quality and safety of its products, but also increase efficiency and reduce costs. These advances demonstrate how Domin continues to shape the future of hydraulics and revolutionize the sector through advanced manufacturing techniques.
