Today I’ve been asked to 3D map and then 3D print an entire Scottish estate! The bloody place is 30 KM/2 !!! I’m not even sure it’s possible!!! But I’m going to give it a go! Have reached out to some industrial scale 3D printer services for quotes! They want a desktop sized model 3ft x4ft ish of the 7000 acre estate!
All this started from me pissing about with Pix4Dcapture and a cheap 3D printer for fun!!!
The guys that own these places are million/billionaires, they saw the little model house I scanned and printed and said “I want one of the whole estate but bigger”. Course you dont say “no” you go work it out and crap yourself!
Right now I’m thinking of scanning the detailed areas with a drone, getting LIDAR for the boring big stuff (hills and mountains), merging it into a combined model. Then slice that model into pieces that I can print on my little amazon 3D printer (20cm x 20cm!) and then glue it all together again into a big model.
THEN… turn that glued model into a latex mould, make some plaster models and paint them… OR get a bronze cast model of the whole estate!
Think they’d go nuts for a bronze estate! I would if I was a billionaire!
Use a technique called ‘cold cast bronze’.
You can use anything you like actually it doesn’t have to be bronze, but bronze has a warmth and patina to it.
Basically it’s mixing bronze powder with resin, pouring a thin layer into the mould, allowing it to set then infilling the mould with anything you like, plaster, old nuts n bolts, to give it weight, and pouring more resin over the infill. Glue a green beize cloth to the back so it doesn’t damage whatever it’s placed upon when you turn it over after it’s all cured. Remove the mould and rub over the surface to polish the bronze to a patina.
Someone I knew many years ago made large statues from moulds this way. (Venus de Milo, Lions for gate guardians etc)
A bunch of idiots burgled his work place one night and thinking they gotten away with a load of bronze statues attempted to melt them down.
You can imagine the smell when the resin caught fire and all the metal junk inside the statues came out.
@Brian that bronze cold cast technique is the business! I’m def using that! So little update, the client wants a 2mx1m table top model (now I’ve promised bronze!!! Ha ha).
I’m never going to map 7000 acres by drone so I grabbed some lidar data online for the general area, and I’m going to drone map just the interesting detail like the house and farm etc then over lay it onto the lidar model.
Then, to print 2m x 1m I’m going to need to cut the model into 3D printable chunks, like this house test I did. Then glue together, create a latex mould, then bronze cold cast it!!!
