Laser Sin­ter­ing

Complex geometries in highest quality

In mod­ern man­ufac­tur­ing tech­nol­ogy, Met­al Laser Sin­ter­ing (MLS) has estab­lished itself as one of the most innovative meth­ods for pro­duc­ing high­ly pre­cise met­al com­ponents. Especial­ly in the field of pro­totyp­ing and small series pro­duc­tion, this process offers out­stand­ing oppor­tunities to quick­ly and efficient­ly realize com­plex geome­tries.

A detailed look at metal laser sintering

Your ideas, shaped in metal – with advanced laser precision.

Metal laser sintering is an additive manufacturing process where finely ground metal powder is applied layer by layer and selectively melted using a high-powered laser. By repeatedly applying new layers of powder and precisely targeting the laser, a complete three-dimensional part is created – directly from digital CAD data.

Direct Metal Laser Sintering vs. Selective Laser Sintering

While with DMLS the metal powder is merely sintered – i.e., solidified by heating – at MODELLTECHNIK we work exclusively with selective laser melting. This means that the metal powder is completely melted and, upon solidification, forms an extremely dense and resilient material structure, comparable to conventional metal castings or forgings. This technology allows us to manufacture components with particularly high density, excellent mechanical properties, and outstanding surface quality. Selective laser melting is therefore the ideal solution for industries with the highest demands, such as the automotive industry, medical technology, or aerospace. At ModellTechnik, we specifically rely on this state-of-the-art technology to be able to offer our customers customized, high-precision prototypes and small series of the highest quality.

Your ideas in delicate metal structures.

Choosing the right material is crucial for the quality and functionality of a component. At ModellTechnik, we rely on two proven materials for metal laser melting: stainless steel and copper. Stainless steel is one of the most widely used materials in selective laser melting. Its excellent corrosion resistance, high strength, and good processability make it ideal for a wide range of applications – from functional prototypes to components for demanding industrial uses. Copper is renowned for its outstanding electrical and thermal conductivity. These properties make it the material of choice for components in electrical engineering, thermal management, and high-frequency applications. Thanks to our fiber laser technology, we can process copper with high quality – something many standard laser systems cannot achieve.

Additional Materials

Flexibility through strong partners

In addition to stainless steel and copper, we offer our customers access to a wide range of other materials through close cooperation with trusted partner companies. These include: Titanium and titanium alloys | Aluminum alloys and special steels. Thanks to this extended network, we can flexibly respond to special customer requirements and reliably realize even complex projects with specialized materials – without compromising on quality or lead time.

Metal laser sintering in practice

Ar­eas of ap­pli­ca­tion and in­dus­try so­lu­tions

Metal laser sintering offers numerous possibilities for manufacturing complex, high-precision components. Especially in industries where the highest demands are placed on functionality, reliability, and weight, this process is indispensable. MODELLTECHNIK provides customized solutions for a wide range of applications.

Automotive Industry

"In the automotive industry, rapid development of new components is crucial. Using metal laser sintering, we produce high-precision prototypes for complex parts such as heat exchangers, structural elements, and engine components. Our parts meet the highest standards for strength, heat resistance, and dimensional accuracy.

Medical Technology

Medical applications demand high standards in material quality, precision, and surface finish. Using MLS, we manufacture parts such as patient-specific orthoses, device housings, brackets, and development prototypes — made from stainless steel, biocompatible and corrosion-resistant for non-invasive use.

Aerospace

Weight reduction combined with high strength – ideal for MLS in aerospace. We produce durable structural parts, functional prototypes, and specialized components for extreme conditions, precisely manufactured in copper and stainless steel.

Functional Parts and Small Series

In addition to classic prototypes, we manufacture functional components and small series — such as specialized brackets, heat exchangers, electrical contacts, and housings with complex internal structures. Our precise manufacturing and quality assurance ensure geometrically accurate, ready-to-use parts.
