CNC VS 3D printing for automotive applications

There are multiple kinds of digital manufacturing technology used in automotive industry. However, which is the best choice for a project? People always feel confused about that. The rise of production-quality additive manufacturing provides an alternative for CNC machining with its own set of unique benefits.
Products of CNC machines are different from those of 3D printers, because CNC is a subtractive process, which cuts material away from a solid workpiece. On the other hand, 3D printing is an additive process which introduces new material layer by layer.

However, it is now possible to make some parts with either of the processes. Interior panels fit into this category. While CNC machined panels are sturdy and can come from a wide range of materials, 3D printed panels provide a new alternative. This is especially so for rapid prototyping.

Other 3D printed precision auto parts include brake components. Ford has used Carbon 3D printing tech to make a parking brake bracket from epoxy resin. Volkswagen also demonstrated its use in making custom gear shifts.

So, which manufacturing method should you choose? Of course, automotive machining is a common application of CNC machine technology. CNC machining for automotive industry results in durable, reliable car parts. On the other hand, 3D printing provides such a high-speed alternative that helps create ultra-lightweight and highly customized parts.
