BCN3D Metal Pack

Only compatible with the Epsilon Series (Epsilon W50 and W50SC, Epsilon W27 and W27SC)

The Metal Pack is an upgrade for the current Epsilon Series that opens up a new range of applications for BCN3D customers, especially for spare parts, functional prototyping, and tooling, and is mainly aimed at the pharmaceutical, food, automotive, aerospace, and manufacturing sectors. The parts produced by this process have practically identical behavior to those produced by MIM or CNC and offer an office-friendly solution with far more design freedom. 

The Metal Pack includes both Ultrafuse® 316L and 17-4 PH, and a new exclusive hotend for metal, as well as specific accessories, to ensure a smooth printing experience. BCN3D has created a new printing profile for metal for the BCN3D Stratos slicer that avoids the internal tensions of the printed part during the printing process. After printing, debinding and sintering processes can be carried out externally.

Ultrafuse® Metal Filaments portfolio has been developed based on BASF’s decades of know-how within the Metal Injection Moulding (MIM) industry.

How does the process work?

The process is divided into 3 steps: printing a part with the BCN3D Epsilon 3D printers and the subsequent industry standardized debinding and sintering. The result is a final part which is nearly 100% solid stainless steel.

For the printing process, filaments Ultrafuse® 316L and 17-4 PH contain high levels of stainless steel in combination with polymer binders which allow easy printing. The binder content from the printed part is removed through a catalytic debinding process. For the next step, the part undergoes a subsequent sintering process at temperatures right below the melting temperature of the metal, which causes the metal particles to coalesce. The material then reaches its final state through post-sintering, where it achieves required performances in aspects such as hardness and strength.

The user workflow is reflected in the following picture.
