State of the art equipment for thermal processing of 3D printed green parts made from metals, ceramics or MMC’s
State-of-the-art equipment for thermal processing of 3D printed green parts made from metals, ceramics or MMCs. 3D metal printing post thermal processing involves three major steps, which are: Debinding of the 3D printed green part, residual debinding of the brown part and sintering as a final step to obtain a real metal part.
MetalMerger is a thermal processing line that becomes composed based on the type of binder in the 3D printed green part and the metal alloys to be sintered. Different metal alloys may require different atmospheres, for instance: air atmosphere or inert-gas atmospheres or reactive atmospheres or vacuum or even combinations thereof.
Filament Metal FDM (FFF) for 3D metal printing usually consists of around 20 wt% binder and thus requires either solvent debinding or catalytic debinding (this two to be mentioned here as the two most common debinding processes).
The 3D printed green part is treated in the debinding unit. After debinding treatment the majority of the binder is removed and the brown parts move further to residual debinding and sintering in the sintering furnace.
Binder Jetting and Nanoparticle Jetting 3D Metal Printing processes result in green parts with up to 2 wt% binder.
Under this condition debinding in a separate debinding unit may not be required and the green parts can be loaded directly into the residual debinding and sintering furnaces.
THE RESIDUAL DEBINDING STEP TAKES PLACE IN THE SINTER FURNACE PRIOR TO THE ACTUAL SINTERING STEP.
THE METALMERGER SINTERING UNIT CAN BE SHIPPED IN COMPLIANCE WITH EITHER OF THE FOLLOWING STANDARDS:
