Quick answer: Additive manufacturing builds an object one layer at a time instead of cutting it from a solid block.
Additive manufacturing builds an object one layer at a time instead of cutting it from a solid block.
- A digital model is divided into thin layers.
- The machine deposits or cures plastic, resin, or metal material.
- Each layer bonds to the one below it.
- The finished part may need cleaning, curing, machining, or other finishing.
Good to know: The process is especially useful for prototypes, custom tools, medical models, and complex one-off parts without molds.
