TNO has been developing techniques for 3D printing for quiet a time. A fairly new technique in 3D printing is adding material instead of removing material.
The Hyproline 3D is a printer with an eight-meter-long belt with one hundred product pallets with various processing stations. In a batch machine operations can now take place simultaneously in hundred unique variants. With a robot arm that picks up products at a rate of almost one and a half meter per second 3D printing has become extremely fast, cheap and flexible. Think of the creation of unique products such as jewelry, teeth, hearing aids, titanium implants for a hip, jaw or skull and unique lightweight structures.
