According to researchers at ETH Zurich,” have fabricated an 80 m2 lightweight concrete slab at the DFAB House, making it the world’s first full-scale architectural project to use 3D sand printing for its formwork”.
According to Nicholas Cohrs, a doctoral student in the group led by Wendelin Stark, Professor of Functional Materials Engineering at ETH Zurich,”our goal is to develop an artificial heart that is roughly the same size as the patient’s own one and which imitates the human heart as closely as possible in form and function”.
According to ETH Zurich’s Engineering Design and Computing Laboratory, “RETHINK a future that 3D prints artificial organs – imagine a brain and experience the magic of the human mind in augmented reality”.
Heart pump from a 3D printer
According to ETH doctoral student Kai von Petersdorff-Campen,“ My goal was not to make a good heart pump, but to demonstrate the principle of how it can be produced in a single step.
Conventional manufacturing methods are the bottleneck in the development of ventricular assist devices (VADs). The shift to agile, fast and test-driven development practices renders the use of additive manufacturing techniques necessary. A critical component of heart pumps are magnets, e.g. in the driving and bearing system of the impellers in turbodynamic VADs. We have developed a method to 3D print magnets directly into parts by fused deposition modeling. Using that method we printed and tested a functional pump with 10 integrated components”.
World’s Smallest Image printing using 3D NanoDrip Technology
ETH Zurich and a startup called Scrona Ltd. have been announced world record holders for the smallest inkjet-printed color image. They used 3D NanoDrip printing technology to print a tiny image of clown fish around a sea anemone. The image is of the size of a cross section of a human hair. The image is 0.0092 mm2 in area and can only be seen under a microscope.
The image is printed using nano particles called quantum-dots. Quantum-dots can emit lights of different colors depending on their size. Layers of red, green, and blue quantum dots can be created to generate different colors.
Scrona also developed µPeek, a credit card sized microscope that can be used to see the tiny image. The microscope can be interfaced with smartphones allowing you to see it using the smartphone and to take pictures of the image.
