3d printing fabrication   3d printing covered the design of small joints of powder. The exercise was designed to study the possibilities of connecting elements in the x, y, z axis using a single type of connector where you can connect elements only at an angle of 0 degrees or 90 degrees. By rotating these elements can be obtained very interesting shapes.¬†On the other hand, as a result is obtained very fragile connectors and it was necessary to strengthen them with glue.
