A mould is printed using an FFF printing technique. The mould is filled with curable material. The building of the mould and the filling of the mould is performed simultaneously. So for example first a number of mould layers is printed using FFF to create a specific height, and then that height of the mould is filled with a curable material. Next, the curable material is cured using e.g. UV light. This process is repeated until the complete mould is build and filled. The mould can be manufactured using PVA which can dissolve in water.
