New capabilities thanks to selective laser melting
Generative production, additive production, rapid prototyping or rapid manufacturing. These are all names of an innovative production method which offers new, as yet unimagined capabilities for low-cost production of prototypes, spare parts, tools or end products – without the use of special patterns.
Using this future-oriented technology goes without saying for us as a driver of innovation. With the selective laser melting (SLM) process we make it possible for our clients to manufacture metal parts which serve a very wide variety of purposes:
- Low-cost production of spare parts without using a pattern (so-called reverse engineering by scanning the required part for instance)
- Production of prototypes: For initial performance tests or for shortening the time to market (market development)
- Production of end products featuring a high geometric complexity
- Production of tools or tool components (with integrated form-fitting coolant bores for instance)
- Hybrid manufacturing: Manufacturing on a conventionally produced component using SLM
Why turn to the wolfensberger ag?
The design of the parts, the calculation of the production-related deformation, the consideration of required support structures as well as the optimized printing positioning influence the quality of the end products. The many years of experience of our workforce guarantee optimum product engineering which leads to best possible characteristics regarding surface roughness, tensile strength, yield point and notch impact strength etc.
As a material specialist, we also support you in selection of the right material. We can take recourse to in-house developments if conventional materials do not suffice.
What is slm (selective laser melting)?
A high-power laser melts metal powder which is coated continuously by a so-called "blade" in several cycles. When the required part is completed, it can be removed from the excess powder and separated from the metallic substrate plate. The process allows various, geometrically differing parts to be produced simultaneously, which has a positive impact on individual costs.
Clients from various industries use selective laser melting:
- Mould and die constructors
- Mechanical engineering
- Designers / developers
- Light-weight construction
- Clock and watch industry
Egal in welcher Branche.
Regardless of the particular industry, 3D-printing is used wherever visions and ideas turn into reality.
Example products using the selective laser melting process
3d-printing in the sand casting process
We use 3D-printing technology even for producing large parts. Printing sand moulds and sand cores allows us to manufacture parts up to 2000 x 2000 x 2000 mm using the sand casting process.
- Part sizes: Up to 250 x 250 x 300 mm
- Surface roughness: Depending on material, upwards of approx. Ra 2.5 (without reworking)
