I really appreciate all the input guys and I think we will look into this on return from our UK trip this month. The SLA Form1 printer looks good for detail but isn’t available yet in Australia.
Im thinking if I print the concrete structures first in 5 pieces to be assembled the same way they are in real scale that would be a good base. From there I could print the 3 lift shafts separately and the stair structures separately also this may work.
I think Anthony’s suggestion of reinstating the cladding and removing the structures would work better as there will be very little small parts involved if I go for the fully clad finished structure and remove the skeleton.
I think the suggestion of us preparing the model and then paying someone to print the first one is also a great idea just so we can see the results prior to buying a certain printer as I’m sure these are evolving at a significant rate in terms of build size, quality and accuracy.
Again thankyou for your help to all who took the time. I may be back in the not too distant future to call on your expertise once we have a printer on the go!
