 From our tests we observed that both the ratio of the ingredients in the mix and the preparation method are important. The fraction of water normally present in sand forms a strong bond with the water retention agent. After these bonds have formed, it is difficult to achieve a reproducable homogeneous mix because the component used does not gel through easily when water is added. The solution to this is allowing the agent and the water fraction to interact in a single step in the proces. This can be achieved by working with dried sand, or by adding the water retention agent to an already mixed wet mortar. The latter carries with it the disadvantage that an extra step is added to the printing process, namely premixing the wet mortar. From our tests we observed that both the ratio of the ingredients in the mix and the preparation method are important.
