The 3D printers. I mostly use them for student classes and research, but sometimes I need to run test prints to check the machines, so I can have some fun with these too. I’ve printed a tiny Black Pearl ship from Pirates of the Caribbean, a Darth Vader mask, Groot, plus animals and Formula One cars. It’s amazing what you can make.
I help university students and researchers make and test new materials. We work with all sorts of materials, from metals and ceramics to more complex things like polymers (plastics and resins) and biomaterials (materials which can be implanted into the body).
