This three-piece jigsaw puzzle may not be the most complicated but you'll need one hell of a steady hand and some excellent eye-sight to complete it.
Each of the parts is less than one millimetre in size making it the smallest in the world.
It has been created to showcase a new type of injection-moulding technique called LIGA2.X, developed at the Karlsruhe Institute of Technology in Germany.
Current injection moulding at such sizes requires parts be printed onto a substrate layer and then painstakingly removed.
LIGA2.X. does away with this and perfectly formed parts just come straight out of the mould and works with metals, cermaics or plastics.
It could lead to a reduction in the cost of making delicate parts such as watch mechanisms or intricate medical devices.
