The mold creates green parts, which then need to be put into a furnace for bulk sintering. The green parts are created by mixing metal powder and a significant amount of binderlubricant which needs to be burned out before sintering. This debinding stage limits the size of MIM components, which forces the technique to focus only on small parts.
