What’s the difference between 3D printing and CNC machining?

Manufacturing Process: 3D printing is an additive process, building parts layer by layer from materials like plastic or metal. In contrast, CNC machining is subtractive, cutting away material from a solid block to shape the final product.

Material Efficiency: 3D printing minimizes waste by using only the material needed to form the part, whereas CNC machining can produce more waste due to its subtractive nature.

Speed and Cost: For small batches and complex geometries, 3D printing can be faster and more cost-effective. CNC machining is preferable for larger volumes and materials requiring high precision and strength.

Surface Finish and Tolerances: CNC machining typically achieves better surface finishes and tighter tolerances compared to 3D printing.
