Binder Jetting (BJ) can produce small details in metal with very high detail. The process binds metal powder to the shape of the part and is then sintered into a fully solid metal part without pores. The part is printed on a larger scale and then shrinks to the desired size during the sintering process. The scaling is difficult to get exactly right, which means that this process has a relatively large tolerance range. The result in terms of the material properties is very similar to the properties you get through traditional sintering of metal, but through Binder Jetting you can get completely different types of geometries. After sintering, the 3D printed parts can be polished in various ways to achieve the desired finish. Another method of 3D printing in metal is DMLS.
