3D print allows us to produce items with no extra costs or tools such as tools for injection of plastic. The operational principle of 3D print consists of adding material layer after layer and if we look closely at the printed object, we can see those layers with our bare eyes. In most cases these visible layers are not problematic, but sometimes costumers prefer prints that look as close as possible to the original. In that case, we need to extra process the prints with sanding, polishing and/or colouring. An example of this kind of product is this replica of Neanderthal flute. The Neanderthal flute is the oldest known musical instrument ever found in the world and it was made by aNeanderthal man who used a cave bear bone to make it. The flute was discovered in 1995 in Slovenia. We are proud to say that we print the flute replica sold as a souvenir at the National History Museum of Slovenia.
