At my university I have used both out ABS printers and both are very strong; one uses ABS 64 and the other 82 [Don't know what that means].
I have also used the SLA printer. Its clear but is like acrylic in its properties so I would avoid that.
You could easily do an antweight chassis in ABS. While I was watching AWS-40 I asked what thickness people printed to and they said minimum 3mm in Nylon. Go for something like 3mm in ABS and I am sure it will be strong enough against all but the meanest spinners
