We are looking to produce a large chandelier with the design of a looped 3D bent strip (think of those black race tracks for kids) but around 3m long.
Ideally it will be made of a thin aluminum profile, say 100 x 15mm.
Now the only 3D Freeform bending machine I currently know of is at Rainier in Wisconsin, but they only do circular pipes.
Besides 3D printing, I would like to know if anyone has advice on how to manufacture such a luminaire.
I am looking at technologies such as superplastic forming but ideally this will be made of one piece aluminum to be anodized.
