3D-printed models like this allow Caterpillar to set up CMM programs and other systems before foundry parts arrive. 

A long-term goal of the Additive Manufacturing Group at is to explore how additive technologies like selective laser sintering (SLS) and fused-deposition modeling (FDM) could be applied for the production of end-use components, such as low-volume plastic parts or one-off replacements for legacy equipment. However, it has also found ways of improving current production with additively manufactured gages, assembly fixtures and other manufacturing aids.

The 3D-printed part shown above was created to speed up setup tasks for a production line. The part is a model of a forged track link, a component of the chain-like assembly found on dozers and other track-type equipment. In the past, workers would have used heavy models made from wood when creating fixturing and programming CMMs. Or, they would have waited for the parts themselves to arrive from the foundry. With 3D printing, Caterpillar made 36 ABS polycarbonate models of the track link. The lightweight models were much easier to handle and allowed employees to complete setup more quickly. The company estimates that making this change saved $160,000 in time and labor. .
