Patented Objects: Having a patent on an invention or innovation means no one else can create, use, or sell a product without the patent holder's permission. Therefore, 3D printing of a patented object is illegal, and the patent holder could sue for patent infringement.

3D printing or additive manufacturing enables you to produce geometrically complex objects, shapes and textures. It often uses less material than traditional manufacturing methods and allows the production of items that were simply not possible to produce economically with traditional manufacturing.

3D printing can cost anywhere from $3 up to thousands of dollars. It's hard to get the exact cost of a 3D print without a 3D model. Factors such as material, model complexity, and labor affect the price of 3D printing.

Fused deposition modelling (FDM), also known as the material extrusion additive manufacturing technique, utilizes polymers as the raw material (filament). The filament is usually heated to a molten state and then extruded through the nozzle of the machine (3D printer).
