  • Technology

  • Micro Laser Sintering combines the advantages of additive manufacturing and micro machining for the first time. Micro metal parts of incredible accuracy, detail resolution and surface quality are manufactured this way. These advantages result in the ability to manufacture moveable parts and assemblies in a single step.

    The basis of these outstanding results is the combination of a very small laser beam spot size, special micro powder and super thin layers.

    What is Micro Laser Sintering?
    Micro Laser Sintering is a powder bed based additive manufacturing technology, often called Selective Laser Sintering or Selective Laser Melting. Micro Laser Sintering is an industrial technology, providing micro metal parts to several industries.

    Micro Laser Sintering – functional principle
    A 3D-CAD model of the target geometry contains all details of the final part. This CAD model is split into several cross sections, called layers. During manufacturing, a thin layer of powder is applied to a build platform. The powder is selectively fused by a laser beam according to each cross section. After that the building platform is lowered, the procedure of powder coating, fusing and platform lowering is repeated layer by layer, until the part completed.

    Micro Laser Sintering combines the advantages of additive manufacturing and micro machining for the first time. Micro Metal parts of incredible accuracy, detail resolution and surface quality are manufactured this way. These advantages result in the ability to manufacture moveable parts and assemblies in a single step. The basis of these outstanding results is the combination of a very small laser beam spot size, special micro powder and super thin layers.

    The parts are used in any industry requesting small metal parts of high accuracy, smooth surface finish, outstanding detail resolution and complex shapes. Current main industries are Medical, Semiconductor, Mechanical Engineering, Aerospace, Energy and Chemical as well as Jewelry and watchmaking.

    Micro Laser Sintering combines the advantages of Additive Manufacturing and Micro Machining, enabling the manufacturing of parts of incredible shapes. Expect micro parts of very good dimensional accuracy, incredible detail resolution and smooth surface finish even if they are very complex, with internal channels, complex 3D-structures or even complete assemblies manufactured in one shot. This works with thousands of parts as well as with just one customized part, as no tooling is required.
      • Case Studies

      • Additive manufacturing technologies offer unique possibilities to create innovative products. By comparing conventional and additive manufacturing technologies, a function-driven redesign of products is often beneficial. In particular, the Micro Laser Sintering provides a high level of accuracy and detail resolution of the desired micro parts. The case studies of 3D MicroPrint GmbH illustrate innovative solutions for various applications which demonstrate the exceptional potential of the Micro Laser Sintering technology.
          • Case Study flow measuring probes

          • Small probe, big effect – Micro Laser Sintering makes tailor-made flow measurement technology possible

            Accuracy is mandatory in the field of fluid dynamic measurement technology. Flow probes help to determine fluid flows simply and accurately. By means of Micro Laser Sintering, the components are developed flexibly for the respective application and manufactured on demand. Size and shape are adapted according to the different application areas.
          • Case study lattice structures

          • Complex 3D lattice structures – Micro Laser Sintering enables maximum functionality by minimum material use

            Lattice structures are used to save weight without sacrificing stability of parts. Furthermore these structures can also realize functions like shielding, guiding or separating fluids in medical devices, reactors, heat exchangers, fuel cells and other microfluidic applications.
          • Case study grabber

          • Cost reduction by saving assembling – Functional module built at-once by Micro Laser Sintering

            Grabbers or manipulators are used in numerous branches from medical technology to aerospace. Using conventional technologies such a grabber has to be assembled at least of four single pieces. The smaller the parts become, the more difficult the secure assembling of the tiny components is.
          • Case study watch

          • Micro Laser Sintering for highest quality standards – The future at your wrist

            The watch manufacturing has in Europe a century old tradition and is the epitome of elegance, quality and precision. The production of precise serial components is carried out under the highest quality standards. Existing technologies for micro-machining already encounter the limits of feasibility. An additional individualization is only possible under enormous costs.
          • Case study  Frauenkirche

          • Miniaturization with highest complexity – Scaled architectural models

            The Frauenkirche located in Dresden (Germany) is a landmark of the city. Built in the 18th century and destroyed in the World War II, it was faithful reconstructed almost 60 years later. This war memorial became a symbol of peace and reconciliation. A miniature model of the building transmits the message to the world and illustrates the high accuracy of Micro Laser Sintering.

            Example: Miniature model of the Frauenkirche located in Dresden (Germany); scale 1:6100; height 16.6 mm; material 1.4404 (316L)
