3D printing, in relation to 3D modeling, refers to the process of physically manufacturing objects by using 3D models as digital blueprints through additive manufacturing.
- 3D modeling first creates a detailed digital design (e.g., STL, OBJ files) that defines the object’s shape, dimensions, and structure. - 3D printing then takes this digital model and builds the physical object layer by layer, using materials like plastic, resin, or metal, based on the model’s specifications.
In essence, 3D modeling provides the virtual "blueprint," while 3D printing turns this digital design into a tangible, real-world item.
