Maximum capacity build job for radiator
The motor heat sink, which is manufactured by TRUMPF as a batch component for a laser cutting machine, has been completely reconfigured in AM design with integrated cooling channels, which increases the cooling capacity. The heatsink is now a single component rather than a full 10-piece assembly, thus profitability is increased. The new design also opens up further optimisations and economic advantages, which are reflected in the reduced assembly effort and lower manufacturing costs.
Produced on the TruPrint 5000 with 500 °C preheating, a reproducible part quality is achieved over the entire build plate and build height. The intelligent support structure between the parts ensures easy and safe part separation. By stacking the components, the machine handling time can be reduced by 85% per part.
Stacking the components on top of each other utilises the entire build volume, and 329 parts can be printed with one build job.
A fully equipped 300 mm diameter build plate contains 47 motor heatsinks. Accompanying samples are printed for quality control in batch production. These result in a relative density of 99.8% and a tensile strength of 700 MPa.
Additive manufacturing has not only reduced production costs but also significantly simplified assembly due to an integrated flexure joint.
