Laser powder bed fusion (LPBF) is the leading additive manufacturing technology for metals. Due to its precision, this technology can create complex and dimensionally stable parts.
How LPBF works
Laser Powder Bed Fusion (LPBF) is also known as Selective Laser Melting (SLM) or Direct Metal Laser Sintering (DMLS). This technology requires an inert gas atmosphere and a laser to melt metal powder which is stored in a powder bed.
As this happens repetitively layer by layer on the build platform, the material fuses together to form the part.
​
With the help of support structures, LPBF enables complex geometries that are not achievable through subtractive manufacturing methods. Furthermore, this additive manufacturing process requires no additional tooling, making it a cost-efficient manufacturing technology. Another advantage of powder bed technologies is the recyclability of unused powder.
LPBF use cases
As the leading metal additive manufacturing technology, LPBF is used by a wide range of industries on the MakerVerse platform, including automotive, energy, and others. This technology is equally suitable for producing functional prototypes as engineered end-use parts.

Available LPBF finishes
Blasted
An abrasive medium is applied to the component under high pressure. By using different media (e.g., corundum, sand or glass beads), both functional (achieving a certain surface roughness) and optical (polishing the surface) finishing can be performed.
Heat treated
After reaching and remaining at a pre-determined temperature, the material is cooled back down. As a result, the material properties can be specifically adapted to individual use cases.
Painted
Additional color is applied to the printed part, often by a professional spray-painting system. To get the desired output, the part is properly prepared through accurate cleaning and a clearcoat.
CNC machined
Post-processing CNC options include turning, milling, drilling, and more. The advantages include dimensional stability, low surface roughness, and flexibility for customer-specific requirements.
Polished
An abrasive is used to smooth a part's surface. By repeating this process throughout different stages with reduced roughness of the abrasive, you gain a smooth and polished surface.
Tumbled
Parts are reworked by grinding media in a container, where they are deburred, finely ground, and polished by vibration or rotation of the container.
