The characteristics of DMLS/SLM processes are enhanced by BÖHLER materials

Zare offers customers three new materials for DMLS/SLM metal 3D printing technology: M789, W360 and E185 produced by BÖHLER, perfect for final components on specific applications with high added value.

The range of materials that Zare parameterises and offers for production with DMLS/SLM technology is further enriched thanks to the new BÖHLER materials: the M789, the W360 and the E185. Produced by vacuum induction melting and atomization under inert gas, these powders have a high degree of purity, a particle size and a sphericity specially designed for 3D printing.
These properties enhance the characteristics of DMLS/SLM technology capable of guaranteeing lightness, resistance and productivity in the manufacturing of final production elements directly in metal.

Materiali BÖHLER

BÖHLER M789 is a PH (Precipitation Hardened) stainless steel with high mechanical, hardness and corrosion resistance properties. Thanks to these characteristics, the material is suitable for use in structural components that are usually made using high-performance structural steels, such as AISI 4340 and Maraging M300.
M789 steel is more resistant to corrosion than other high performance structural steels, therefore it is possible to avoid the use of galvanic coatings (e.g. Cadmium and chromium VI and III). These properties allow the use of M789 steel for the construction of shafts, supports, dies and moulds, gears and impellers that operate in corrosive environments. Also, this material is Cobalt free.

For hot work, however, the ideal choice is BÖHLER W360 steel.
This steel has all the characteristics necessary for the production of components used for hot work such as: high thermal conductivity, good wear resistance and compressive strength, possibility of being heat treated in vacuum, hardness between 42 - 60 HRC and good weldability, a particularly useful feature in case of restoration and regeneration of existing products.
Compared with the classic H11/H13/1.2367 hot work steels, the BÖHLER W360 has decidedly superior performance, making it particularly suitable for the production of moulds and inserts for the following applications: gravity casting and die casting, open and closed die forging, hot forming (direct and indirect), blanking, blowing and moulding of glass, stamping and blanking.
Finally, thanks to its properties, BÖHLER W360 steel can be used for the manufacture of nozzles, extractors and inserts in the moulding of filled (up to 60% vol of fibreglass) and unloaded polymers and high-tech polymers.

Materiali BÖHLER

The low alloy BÖHLER E185 steel is designed for components to be used in particularly demanding sectors such as motorsport, automotive, earthmoving machinery and precision mechanics.
The low carbon content facilitates moulding and the material can be used for both final elements and prototypes. Thanks to its chemical composition, it is also the first steel specifically designed for the production of 3D printing components that undergo classic thermochemical treatments, such as case hardening, nitriding and carbonitriding.
BÖHLER E185 is therefore the ideal material for the production, by means of 3D printing with metals, of components for transmission parts such as gears, pinions, pins, crowns, shafts, synchronisers and bevel gears.

Additive production is a complex process where each phase must be meticulously prepared and carried out always taking into consideration the production as a whole and the result to be achieved.
Choosing the best material for the intended application is only one of the phases.
The specialised technicians at Zare, our Additive Team, are able to offer expert advice both on the process as a whole and every single phase, fully exploiting the properties of the materials and combining them in the best possible way with the advantages offered by the various 3D printing technology available.
