3D printing and CNC machining are two of the most popular manufacturing processes<\/a> today. Both methods rely on digital control systems to enable the quick production of prototypes and are suitable for creating accurate, customized end-use parts.<\/p>\n\n\n\n

However, they differ in almost every way \u2013 they are even direct competitors when it comes to producing solid parts. The biggest difference is that one method builds parts layer by layer, while the other works by removing material. If you find yourself at a crossroads choosing between CNC machining and 3D printing for your products, read on to find out more.<\/p>\n\n\n\n

What Is 3D Printing?<\/h2>\n\n\n\n

3D Printing, also known as additive manufacturing, is a process that creates three-dimensional objects from a digital model by adding material layer by layer. The process begins with a digital model, which can be created using CAD (Computer-Aided Design) software, obtained from a 3D scanner, or downloaded from online repositories. Next, the model is imported into slicing software, which divides it into numerous two-dimensional cross-sectional layers that serve as a blueprint for the printer. The slicing software then converts these layers into a series of instructions\u2014often in G-code\u2014that the 3D printer can understand. Additionally, if the model contains overhanging parts, the software may generate support structures to ensure proper printing. Finally, the printer follows these instructions, depositing material layer by layer and bonding each new layer to the one beneath it, gradually building the complete object.<\/p>\n\n\n\n

3D printing systems started entering the market in the late 1980s when Chuck Hull invented stereolithography (SLA), the first 3D printing technology. With ongoing research in new materials and technological advancements, more 3D printing techniques have emerged. Common types today include:<\/p>\n\n\n\n
