3D printing with metal Renishaw / Renishaw laser melting systems

3D printing with metal printer Renishaw is a pioneering additive manufacturing process which can produce a fully cohesive, metal parts directly based on 3D CAD models from a wide range of metal powders.

Blend Renishaw laser manufacturing technology is incremental, which uses iterbowy fiber laser of high power for melting fine metal powders useful for forming three-dimensional parts.

The manufacturing process uses a 2D cross section of 3D CAD model of a thickness of from 20 to 100 microns. In the process of building the object, applying a uniform layer of metal powder using a coating apparatus, and then fusing the layers under strictly controlled conditions of an inert atmosphere. Upon completion of this stage, the object is removed from the powder bed and the process of heat treatment and finishing depending on the application.

Typical applications for 3D printing technology of metal (melting laser):

  • functional testing of high-quality production of prototypes,
  • generation biocompatible components or highly complex geometric shapes,
  • small-lot production of metal parts with complex shapes with special materials.

News use of 3D printing by Renishaw

Lightweight titanium bicycle frame printed 3D 

Renishaw company producing the additive, they joined forces with the Empire Cycles and together they built a titanium frame called the MX-6 Evo Mountain Bike, usually done with a single piece of aluminum.

The frame was constructed using a printer SLS called AM 250 manufactured by Renishaw. In this process, high-power laser selectively sinters the powder together with the titanium alloy. The layers are being added one after the other, until the rise of the frame ready. The elements thus formed are connected to each other by an adhesive.
Because titanium has a higher density than aluminum, the frame must therefore be curtailed, but in such a way as not to reduce its strength. As a result, the final printed frame EVO weighs less by 33% than the original aluminum counterpart, and thus less than one kilogram! Tested strength seatpost same, it appeared that meets with a six-reserve standard for mountain bikes EN 14,766th strength of the entire frame is still being investigated.

The question is why printed titanium frames can be cheaper than those produced in the traditional production process?

First, a process of 3D printing metal SLS is no waste, the titanium alloy powder that is not sintered, can be used to build the next frame. There are also no special treatment is often problematic, which would have to be used for the method of casting metal. Another advantage is the possibility of quick change frame structure, if nece
