Description

What is 3D Metal Printing and How does it Work?

3D Metal printing is a revolutionary technology that produces “impossible-to-make” end-use metal parts directly from your CAD data. The mechanical properties of DMLM parts are comparable to cast parts or machined component. The advantage of the process is that the more complex or feature rich the component, the more economical the process becomes. 3D metal printed parts are fully dense, incorporating complex geometries and precise internal features that cannot be made with traditional machining alone. Designs can be made quickly with a minimum of material waste while maximizing strength, making them ideal for next-generation applications in aerospace, medical, automotive and other industries.

Direct Metal Laser Melting (DMLM) parts are fully dense, incorporating complex geometries and precise internal features that cannot be made with traditional machining alone. But many parts have features that still need to be post-machined, such as threading tapped holes.

Designs can be made quickly with a minimum of material waste while maximizing strength, making them ideal for next-generation applications in aerospace, medical, automotive and other industries.

3D Metal Printer

Renishaw AM250AM250

Renishaw’s AM250 is a state-of-the-art 3D metal printer for rapid prototyping and manufacturing. 30µ metal powder is laid down onto a metal substrate and an ytterbium laser fuses that first layer to the substrate build plate. The plate then drops down by one layer, typically between 20µ and 100µ per layer, then another layer of powder is laid down. The second layer is then fused to the layer below. This process repeats for hours until a 3D metal object materializes on the substrate. Once the whole process is completed the machine operator will brush away all un-fused powder revealing the 3D printed metal part. The finished part is typically 99.8% dense with mechanical properties rivaling those of forged metal parts.  In addition,  Renishaw has developed a special support structure that allows for a stable build to counteract thermal stresses induced during the laser melting.

The Renishaw AM250 uses a high-powered yterbium laser to melt successive layers of metallic powder into a fully-dense solid with mechanical properties equaling those of a cast part. Your CAD file is sliced into multiple 2D layers for deposition, with supports added to insure the integrity of the structure during the build. Resolutions of 50μ or better are achievable depending on design geometry.
