Urethane Molds

thingiverse

To create one-off urethane parts, craft specialty molds using PLA. This allows for easy demolding due to the PLA's dissolvability. For optimal results, ensure a 180°F urethane temperature and maintain appropriate PLA wall thickness to prevent sagging. To produce multiple urethane parts, create silicone molds within PLA molds; these cure at room temperature and can have thinner walls. Employing PLA's dissolvability simplifies the process and enables intricate designs.
