3D printers are modern devices used to create objects on the basis of a computer-rendered 3D model. The very idea is 30 years old, but has only recently been used at such a large scale. Objects can be printed in wax or in light-cured materials, or applying more advanced technologies, including polyamide or metal powder sintering, or resin sintering with the use of a laser or UV light emitters. The objects produced with the use of a 3D printer are very durable.
