Love that delta, my sort of geometry.
There was a British machining robot a couple of decades ago called 'Gadfly', that used a double delta geometry, and as the name implied, was very quick, but I'm danged if I can find any pictures of it via google images.

The next piece of kit you want is a vapor bath - to make your prints all smooth and shiny. Acetone works well for ABS, and I've had some success with methyl ethyl ketone (MEK) for PLA. Chlorinated solvents are supposed to be better for PLA though (methylene chloride maybe?)

Not really 'dangerous'. A few simple precautions is all you need (eg well ventilated area, no flames). The solvents listed are usually available at the hardware store, as paint thinner (MEK), PVC pipe glue (tetrahydrofuran), paint stripper (dichloromethane). Its no worse than filling up your car at the gas station.
