Are we ready to get a whole motorcycle out of the printer? Including the tires? A Berlin technology company says yes – and presents a roadworthy prototype with electric motor.

A new 3D printing process produces tailor-made and affordable bone implants made of a special plastic. A cold plasma jet stimulates the growth of bone cells in the plastic framework.

The photo shows a plasma jet that strikes a cube-like plastic framework.

A so-called plasma jet coats the framework structures for bone implants and thus stimulates the growth of bone-forming cells.

University of Washington engineers have developed a technology that allows devices from the 3D printer to send signals without the need for a battery and expensive electronics .

Additive technology skeptics repeatedly invoke component size constraints. Not that it would be trivial in the metal-cutting world to manufacture large precision metal components, but a process could now prevail that unites both worlds.

It is a logical step in the maturity of a technology that standardization processes must be run through to ensure widespread use. However, additive manufacturing threatens to become the plaything of the powers.

When Chuck Hull invented the plastic 3D printing process of stereolithography in the early 1980s, Probably the least thoughts have flowed into the topic of standardization. In the meantime, however, additive manufacturing (more…)

A young, dynamic start-up and a global corporation? That’s difficult to put together, one might think. However, in the field of additive manufacturing, Siemens is part of the open ecosystem and shows at least the traits of a young and dynamic small business, as the following article shows.

Asked about the mega-trends, many experts are responding to Industry 4.0 and the Internet of Things. But growing and unstoppable is the interest in industrial 3D printing, which would not be conceivable without digitization. New alliances are also being created in research in order to drive developments forward. The head of the focus project “futureAM” explains his goals in an interview.

Machine concepts must reflect the demands of the market. This is especially known to contract manufacturers, who have to react flexibly to changes in their customers. The following example shows how this can also work when using additive manufacturing methods.

CAD data is usually available or will be developed together. However, program corrections can also be made on the control, as here by a Femec employee.

Injury or infection of the human cornea can lead to blindness. A transplantation that saves eyesight often fails because of the need for donor organs. For the first time, British researchers have succeeded in producing a human cornea with biotin in a 3D printing process.

Steve Swioklo and Research Director Che Connon (right) from Newcastle University show a cornea printed with their biotin.

Printing concrete instead of pouring, this idea is not entirely new. To build an entire settlement of 3D-printed houses – this is the Dutch city of Eindhoven entering new territory.
