How Will Additive Manufacturing Assist in Metal Casting?

Additive manufacturing, a straight forward method, provides metal casting companies with the ability to reduce lead times and production launch risks.

FREMONT, CA: Metal casting is now experiencing high demand with every car, train, truck, and tractor or construction vehicle having a cast in it. Additive manufacturing (AM) is one of the newest manufacturing methods that replace the oldest manufacturing method while disrupting metal casting. AM is used to create the fixtures, jigs and tools like sand molds and core and then to manufacture parts by conventional means of metal casting. It is otherwise known as 3D printing which is changing the world around us. Additive manufacturing is a transformative approach to industrial production that allows creating lightweight, robust parts and systems. It will help meets the desires to reduce cost, risk, and timing in production programs.

The technique offers several methods to manufacture parts with metal including Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS), Binder Jetting, and Lost-Wax Metal Casting. While SLM, DMLS and Binder Jetting use 3D printing metal powder to create parts, the latter uses the 3D technique printing for copying the master object in wax.

Additive manufacturing can excellently complement traditional production methods and improve them. One excellent example of combining AM and Classical Foundry is 3D printing the replicas of the master objects. The technique speeds up the pre-production process of traditional metal casting. Additive manufacturing has much more stable production process. Additive Manufacturing gives the freedom one needs to design precisely the model while providing with fast results, and it can highly improve the production system.

Components having intricate parts, particularly small components, can benefit from the additive manufacturing processes. Also, the small elements with moving pieces require strict manufacturing tolerances and highly controlled assembly processes to eliminate the number of component defects. Utilizing the additive manufacturing technology, manufacturers can print small components with extremely precise tolerance. This reduces failure risk while improving product quality. Further, this technology can remove financial barriers that halted many competitors from entering the market place. Thus, 3D printing enables to produce a greater range of shapes and designs and creates pieces having a robust finish.
