Metal Binder Jetting (MBJ) is a powder bed based 3DP technology. MBJ spreads fine powder across the build bed, layer by layer.
On every layer of the loose powder a binder is precisely applied to hold the powder of the actually printed part together. This is repeated layer by layer to print a full box of parts. The surrounding loose powder holds the printed parts in place, so no supports are needed. After printing is completed, the parts are carefully removed from the powder bed, while the powder can be reused.
After printing and de-powdering, the parts require debinding and a subsequent sintering process.
