Last September, Janulus, a company founded by Einar Agustsson in Minnesota, presented the Trinity Portable Wind Turbine Power Station on Kickstarter. Its product hollows individuals to harvest the power of wind almost anywhere. In this project, the team used 3D printing to create the prototypes of the wind turbine. With more the $150.000 in pledges, the campaign reached three time the needed amont and has been one of the highlight of the 3D printing industry last year.
In the early stages of product development, both the base and the blades were made through additive manufacturing. Thanks to this successful prototyping phase, the team has planned to developed the product in four different sizes with different amounts of power. The entry model, the Trinity 50 (priced around $369 for the first batch) is targeting individuals with limited needs on a camping trip while the biggest model will be able to power a car or a home.
2. Sand 3D printing using the sun
This year, we’ve also seen a great project lead by Markus Kayser, who built a 3D printer that uses the sun to 3D print sand. Not too different from the SLS 3D printing technology, the printer invented by Markus Kayser uses reflectors to concentrate a beam of sunlight on a thin layer of sand. The beam of light sinters the material. By repeating the process layer after layer, the machine is able to build object made of sand.
The whole project provides both an innovative option to 3D print a great material but also offers to use a clean energy that’s accessible in a lot of developing countries.
