Uddeholm, a pioneer in high performance tool steel solutions, proudly presents its latest development - Dievar powder for 3D printing, specifically designed for the demanding requirements of the die casting process. This innovative material transfers the proven properties of Dievar hot work tool steel into additively manufactured mould inserts and components such as runners to optimally meet the challenges of die casting.
Over the years, manufacturers in various industries have experimented with the use of 3D printing in tooling applications, recognising its potential to increase efficiency. In die casting, the key benefits of additive manufacturing are avoiding build-up and metal corrosion, reducing cycle times and improving part quality.
The key features of Uddeholm Dievar for 3D printing are:
1. efficient thermal management: given the extreme heat in the die casting process, Uddeholm Dievar for 3D printing relies on conformal cooling. This enables precise placement of cooling channels to optimise the mould temperature. This leads to improved process stability, optimised cycle time and higher part quality with reduced shrinkage porosity.
2. excellent material properties: In contrast to conventionally used powders in the laser powder bed fusion process, Uddeholm Dievar offers exceptional mechanical properties. This optimises conformal cooling designs and minimises common problems such as build-up, erosion and thermal fatigue.
3. high ductility and toughness: Uddeholm Dievar for 3D printing is characterised by outstanding ductility and toughness. These properties are critical to prevent thermal fatigue and cracking that could otherwise lead to water leakage.
4. versatile printing conditions: The versatility of the material allows it to be printed in both cold chamber (200 °C) and high temperature (500 °C) systems. This gives manufacturers the flexibility to design complex geometries while maintaining excellent material properties.
Uddeholm Dievar for 3D printing represents a milestone for die casting. By skilfully combining the advantages of 3D printing with advanced tool steel, it offers die casters a comprehensive solution to successfully overcome specific challenges. Uddeholm Dievar for 3D printing gives manufacturers the opportunity to increase their mould life, optimise production processes and significantly improve the quality of their parts.
