Students at Vienna Institute of Technology create speedy 3d printer!

Having recently developed the worlds smallest 3d printer, the Vienna Institute of Technology has once again made its way into the headlines, this the development of a polymer and laser technique that promises to speed up the printing of minute 3D objects.

The key to this technology lies in the fluid polymer developed at the university along with the use of mirrors to rapidly direct the light. When hit by the centre of the laser beam, the polymer absorb two photons which result in the activation of the molecules. This in turn leads to a chain reaction with other components of the resin (monomers) turning them into a solid.

While offering unparalleled speed this 3D printer does not compromise on accuracy with the team of students successfully building a detailed micro model of the Tower Bridge along with a 285µm Formula 1 speedster.

The team are hopeful that the increased speed and an ability to build much larder objects (relatively speaking) will lead to the adaptation of this speedy 3d printer in the medical industry. The 3D printer is likely to have further applications in the construction of parts of nano engineering.
