We're currently trying to choose the material for the sides of the akkupack project, and due to laser-cutting Aluminium being not quite expensive, but still costing a considerable amount, we're looking at alternatives.
Acrylic would be one suitable candidate, though the brand-name acrylic costs around 40€/m².
I still have some Kraftplex (pressed cellulose fiber) around and we did some very unscientific stress testing on that. It unfortunately doesn't quite make UL94.
@datacop i mean sure, but i can't laser cut it and i don't want to mill it either (FR4 dust is *nasty*). also FR4 plates are readily available but still quite expensive. And after quickly checking double the cost of acrylic it seems :(
It's really just for the housing parts of the mechanical design. Oh and Kraftplex is carbon-neutral and very easily recyclable, so there's that too ;)
@ln full ack, basic idea was full fr4 manufacturing including silkscreen is quite easy, as long as you don't want to do it yourself. But it's definitely not the best and sustainable material.
