The friends of the club @aleiaeiactaest made a multitude of buildings for Warhammer 40000. They used polyurethane resin and thin Gothic sci-fi moulds. They had all the molds and several repeated molds to boost production and speed. The use of resin deteriorates the silicone but there are many pieces that the molds offer us. To make the joints and glue the resin pieces, we use cyanoacrylate with baking soda to reinforce the joint and give more volume to the joint. We can also add a bead of hot glue in the areas to reinforce the area.
Thanks for sharing mates!
