It has been a while since the first 3D printer appeared on the market. The idea was that in time we could print everything, but in practice things are not going that fast. But as an entrepreneur you can benefit a lot from the use of a 3D printer. Developments have not stood still, and nowadays you can save a lot of time and costs by using 3D printing. For example, suppose you need a prototype of a product you are developing. With 3D printing you have a design in no time that you can test, improve, and reprint.
