After my experiment to make a silicone mould from a 3D printed version of the teeth I then made a series of casts using polyurethane resin. This was a simple process using two parts mixed in equal measure poured into the mould and then left to cure for an hour, the resin naturally has a pale fleshy colour that gave an interesting effect to the final casts. These appear soft and malleable but in actual fact are hard and sharp. Each one has its own mistakes or differences where the resin has cured slightly differently or went over the edge of the mould, this shows the notion of making copies and each being imperfect to the next. Each time a copy is made a different set of teeth is achieved, in this way they are no longer just a copy of the original 3D print they are originals in themselves.

The next step in this experiment is to test the inclusion of a pigment to alter the colour of the resin, for this I have tangerine orange polyurethane pigment. It will be interesting to test the how the different amounts of pigment affect the colour and if it is possible to achieve a marbled effect.
