Among 3D printing technologies, direct metal laser melting (DMLM), also known as selective laser melting (SLM), is an additive manufacturing process that uses a high-power laser to fuse metal powder particles, creating complex three-dimensional objects from a computer-aided design (CAD) file. This is a powder bed casting technology, which means that the part is built up layer by layer from a bed of metal powder.
DMLM has several advantages over traditional subtractive production methods, such as machining and casting.
It can create intricate geometries with internal voids, undercuts, and freeforms that would be difficult or impossible to produce with traditional methods, and it eliminates the need for tooling because the part is built directly from the CAD file, reducing production time and costs.
With direct laser melting, nearly sharp shape quality and mechanical properties comparable to those of wrought metal are achieved.
The DMLM is suitable for rapid prototyping and low-volume production to produce parts quickly and with minimal scrap.
One of the best DMLM machines on the market is GE Additive’s Concept Laser Mlab Cusing 200R.
It is a versatile machine that can be used to create a wide variety of parts, including prototypes, production parts, and tooling.
The Mlab 200R can be used to process a variety of metal powders, including stainless steel, titanium, nickel alloy, and cobalt-chromium alloy.
The MLab Cusing 200R is equipped with a filter system with four filters that require frequent replacement, especially during heavy use. As a result, the cost of this consumable is significant.
When the customer came to us with a request to reduce operating costs, we analyzed the problem and developed an alternative: replacing the four filters with one.
Compared with the original replacement, this solution not only reduces costs but also increases service life, as the filter area increases by about 25%; the overall benefit to the customer is about -50% on operating costs.
Depurex specializes in custom filtration solutions to solve special performance needs or to reduce costs.
Our strength lies in our in-depth knowledge of filter materials and solutions, design capability, and extreme flexibility that enables us to produce even small quantities.
Please contact us without hesitation to submit your filtration problem to us.
