+## Going Further
+
+To take this week's work a step further, I'm going to make the same mold in resin to improve the surface finish.
+
+To do this, I import the mold model into the Chitubox software. Models should be positioned at an angle, with the cleanest surface facing upwards.

+
+I export the file, put it on a USB stick and open it in the *Elegoo Mars 2P* resin printer. Printing takes 3 hours. The result is shown below.

+Once the supports have been removed, the impregnator is placed under UV light for around ten minutes to complete the curing of the resin.

+
+The result is a well-cured mold with an improved surface finish compared to PLA. I then tighten the mold to prevent leaks during casting.

+I prepare the polymer to be cast. Here I want to use a polymer that cures fairly quickly, so I choose Ecoflex 00-35 Fast. I prepare the dosages, which are in a 1:1 ratio.

+I can then cast the ecoflex. I have to be quick because the pot life is 2.5 min.
