A World First – 3D Structurally Coloured Objects

Professor of Polymer Chemistry Markus Gallei and his doctoral student Lukas Siegwardt, from Saarland University, Germany, have created ‘perfect polymer particles’ (ie. particles of an identical size and shape) with a hard centre and soft shell, for building 3D-printed structurally coloured objects – something that has not up to now been possible.
