Pastry chefs use a very similar method to 3D printers – they make their cakes in layers. In doing so, they encounter problems that also arise in metal 3D printing – the layers must be uniform to produce a beautifully shaped cake or a dimensionally accurate component. There are new findings from the science confectionery about how to achieve the uniformity of the layers in metal 3D printing.

In one of the last articles we introduced you to the principle of computer tomography. The MAPEX at the University of Bremen X-rays objects, analyses and evaluates the results to gain information about material properties. In this new article, we go on a journey through time. We uncover what was hidden in the past, draw conclusions from the present and evaluate the benefits for the future. The shard shows itself in a new digital guise, which, in addition to new possibilities, also harbours risks.

In our last article, we told you about our FORAREX project, which we developed within the framework of the German-Swedish REXUS/BEXUS programme.
But what exactly does this REXUS/BEXUS programme entail? And who can participate?

What do a torn ligament in the ankle joint and an air bubble in a shard from the 16th century century have in common? Both can be determined and measured non-destructively. With a computer tomograph.
What is it about the 2D wonder material that makes physicists and science fiction fans dream of the future?
We will find out what the hype is based on and how we can produce this material of superlatives at home.
