3D CNC machining
In the 25 years since our acquisition of a Thermwood 5 axis CNC milling machine the sculpture landscape has changed dramatically. Sculptors now have the option of scanning people and animals, sculpting digitally, AI has become an option for some, or scanning previous works and having them enlarged to suit new installation locations and opportunities.
Working from obj or stl files, we scale up the image, split/divide the model into pieces to fit the machine’s table size, plot the cutting paths and parameters and then send the file to the milling machine. The machine cuts the sculpture out of either white EPS foam or blue XPS foam.
The final pieces are assembled, glued together and the surface is given a light sanding, the sculpture can then proceed to other moulding or finishing processes depending on what type of material the end product is to be made from.
This has become a favourite workflow for bronze sculptors who receive the foam sculpture and then apply a 2-5mm coating of plasticine over the entire surface, give it their signature finishing style, and then send the sculpture off to the foundry to mould and cast in bronze.
3D CNC machining is now an advanced way to automate processes previously done by hand. This new solution provides the capability to turn digital files into 100% accurate, large scale sculptures and real world 3D objects in a shorter time frame.
Large, one off digitally designed sculptures for film sets can now be handled in a more streamlined digital workflow ensuring the 3d model that has been digitally sculpted by the Art department and approved by the director, is accurately replicated in foam using the 3D CNC machine.
