Hi Rob!
Great to hear you're going to print this costume!
I'm printing this kit for almost 3 years already and I strongly believe that this kind of production is the best for this and many others kits!
To print your chest/back plates you'll need at least 40*40*40cm printer value.
Shins requires at least 42cm height (Z).
Thighs - 35cm (Z).
These are approximates, cuz all depends on your sizing.
I wouldn't recommend to use ABS, due to high curving rate during cool down. This will affect all thin parts: chest, butt, cod, shoulders.
PLA preffered as for me.
HIPS - best one))
Hope this help, mate!
