This is based on the paper A simple, low-cost conductive composite material for 3D printing of electronic sensors by leigh et al if you want to look it up. Warning – this used a highly volatile solvent and you really need to do it in a fume cupboard, very well ventilated space – or outside – and resist the temptation to peer in while having a cigarette! – it uses
7g polycaprolactone,
1.125g graphite,
100mL dichloromethane
though you can use acetone or ethyl acetate as the solvent and conductive carbon black as the additive
Lessons from off gird: Off grid living involves rethinking relearning how you look at EVERYDAY things. Even a project that involves a simple GLUE gun!!
When you live off of solar you HAVE to see things more conversantly. Think about your household projects and what they use for electricity? COULD you do it without electricity?
TRY!
