Same Destination of AM and MIM technology- Additive manufacturing by sintering is taking off

3D printing based on sintering - powders, feedstock?and equipment using MIM

1.?Metal powder less than 30μm

2.Use the feed to make small dough (30~50 μm), pellets , rods and Films.

3.?Catalytic degreasing, negative pressure degreasing.

4.?Vacuum and partial pressure sintering, hydrogen sintering

?New technology of 3D printing based on sintering method

1.The MIM feedstock?is directly extruded (MEX, FDM...), making a single green part like plastic extrusion, the MIM feed is extruded and then degreasing and sintered to obtain the finished product

2.Using the binder jetting method (BJT), the binder is sprayed onto the powder layer laid on the powder bed to form a green-like 3D printed part, which is then degreasing and sintered

3.Using Selective Laser Fusion (SLF), the feed pellet (30~50 μm) that has been processed by Core Shell is fused to obtain a green body, and then degreasing and sintering is carried out.
