Metal laser sintering is a rapid prototyping method for producing functional metal prototypes in batch sizes of 1-5 units. The model to be created is manufactured directly from 3D volumetric data by melting and solidifying powdered metal with a laser beam in a layering method (direct metal laser sintering). The layer thickness ranges from 20-100 µ depending on the material. A wide range of components with any level of geometric complexity can be created in the construction space.

Direct metal laser sintering (DMLS) is the most suitable prototyping method for metal prototypes that require medium to high level precision. This method is extremely useful especially for diecast prototypes with complex geometries. There are no high-cost casting molds with mold inserts and cooling channels or time-consuming programming of milling paths as is required with CNC milled prototypes.

Whether suction flanges, pressure regulators or movable hinges, metal laser sintering is the ideal method especially for cast prototypes and batches up to five units.

Advantages of metal laser sintering:

• Hard, solid metal prototypes
• A large range of materials can be used
• Suitable for batches 1-5 units
• Greater complexity does not increase the cost
• Outstanding mechanical properties
• Moderate to high level of precision
• Good surface quality (residual pore area of approximately 3-5% which can be improved by heat treatment and polishing)
• Very short production times
• No supporting geometry is required
• The component is easy to change
