This binder jet printer can make large engine parts, such as crankshafts and cylinder heads. While 3D printing is likely never going to be able to produce fenders fast enough for high-volume production, at least one type of the technology — binder jet printing — is making big strides in the size of parts it can produce and the speed at which they are cranked out.

It is becoming an important production tool as the industry shifts from the internal combustion engine to electrified powertrains. The auto industry is a good fit for binder jet printing because the machines can make multiples of identical parts at one time, and they can make those parts from a growing variety of materials. A binder jet printer can use sand, plastic or several types of sintered metal to create parts. The material is deposited in powder form one layer at a time […]
