A detailed look at metal laser sintering
While DMLS typically involves sintering – where metal particles are fused by heat without fully melting – at MODELLTECHNIK, we exclusively use Selective Laser Melting (SLM). In this process, the metal powder is fully melted, resulting in a highly dense and strong material structure comparable to conventional cast or forged metal components. This technology allows us to produce parts with particularly high density, excellent mechanical properties, and outstanding surface quality. For industries with the highest demands, such as automotive, medical technology, or aerospace, selective laser melting is the ideal solution. At ModellTechnik, we deliberately rely on this state-of-the-art technology to offer our customers individualized, high-precision prototypes and small series at the highest quality level.

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.

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
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 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.
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.
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.
The cost of metal laser sintering is influenced by a variety of factors. At MODELLTECHNIK, we place great importance on transparency and fair pricing that reflects the specific requirements of each customer.
Factors influencing the costs
Choice of material:
The selected material plays a keyrole. For example, stainless steel is generally more cost-effective than copper, which is more complex and demanding to process.
Size and complexity of the part:
The larger and more complex the part, the higher the material and production time requirements. Delicate structures or internal geometries increase build time and the programming effort needed for manufacturing.
Layer thickness and build time:
A finer layerthickness results in better surface quality and more precise detailing but also extends the build time. Likewise, the height of the part directly affects the duration of the production process.
Post-Processing:
Depending on the surface quality and dimensional accuracy required, additional post-processing steps such as milling, grinding, or polishing may be necessary. These services are factored into the overall project cost.
Number of units:
Single-unit production often results in higher unit costs, as the efforts for data preparation, build job setup, and machine setup times are fixed. In small series production, these fixed costs are spread across multiple parts, reducing the individualcost per unit.
Cost Efficiency at MODELLTECHNIK
Our focus on prototypes and small series allows us to offer economically attractive solutions even for smaller batch sizes – without compromising on quality or precision. Thanks to our experienced team and optimized processes, we can implement projects efficiently while remaining flexible to individual customer needs.
For those who value the highest material quality, excellent workmanship, and quick project turnaround, MODELLTECHNIK offers a powerful partnership – providing outstanding value in the field of selective laser sintering.
For those seeking the highest quality, reliability, and customized solutions in metal laser sintering, MODELLTECHNIK is a proven and committed partner. Our specialization in prototype and small series production, combined with our technological expertise, sets us apart.
Tailor-made solutions instead of mass production
At MODELLTECHNIK, we deliberately focus on individual customer projects rather than mass production. This allows us to respond flexibly to specific requirements, develop innovative solutions, and deliver quality precisely tailored to the intended application.
Expertise from over 35 years of experience
With more than three decades of experience in rapid prototyping, model and moldmaking, and additive manufacturing, we understand our customers' challenges in detail. This extensive know-how flows into every project – from consulting and production to quality assurance.
