SLM® Metal Powder & Material Parameters

It only takes 3 tools to make you successful with metal additive manufacturing:

1. The SLM® machine fitting your needs
2. The metal powder that defines the later purposes and functionality of a part
3. Precisely engineered SLM® parameters as the missing link.

Our open parameters are the result of our vast experience in multi-laser technology and a diligent development and qualification procedure. In conjunction with the open architecture philosophy, we together with our partners have unlocked more than 45 materials to date – and counting.

SLM® Materials

Open architecture makes it possible: the largest metal portfolio of any metal AM company. We and our partners have successfully worked with more than 45 materials up to this day.

SLM® Parameters

The missing link between machine and metal powder is your ticket into the world of SLM® : our precisely engineered and thoroughly validated SLM® parameters. They are key to produce fully functional parts with properties you can expect and rely on. We keep it simple and offer three categories to you: from high-resolution complex details (Precision) up to the highest build rates (Productivity) or right in between (Prime).

Integrated Powder Handling

When working with metal powders, there is a range of standards including staff care, handling and storage of materials, housekeeping requirements, audits and documentation. All companies operating AM systems should carry out risk assessments and develop an understanding of the regulatory framework and their health and safety obligations. At SLM Solutions, we have immense experience in metal AM and have developed a deep understanding of the risks of metal powders and the laser powder bed fusion process (LPBF). We have designed our systems to overcome these risks and protect users and operating companies.

Depowdering Partner: Solukon

The post-processing of components in the Additive Manufacturing process is a significant step. Due to complex geometric shapes and, for example, internal cooling channels or internal structures, depowdering can become complicated and time-consuming. Solukon, our preferred supplier of powder removal and processing systems tackles these issues with its unique SPR^® technology (Smart Powder Recuperation). Their depowdering systems remove loose powder from metal laser melted parts within a sealed process chamber, using adjustable vibration and automated two-axis part rotation while recovering superfluous powder.
