Recently, we use Rapid Prototyping to make mould for casting two bronze sculptures: football players.
The artist make 12 inch tall maquette; then he scans the maquette to generate Digital file (STL format).
We use the file for Rapid Prototyping and bronze casting. Here is the progress.
This is the maquette of the sculpture, 12 inch tall. The maquette is to be scanned by a 3d scanner.
The artist scan the Maquette with a 3D scanner and generate the 3D mold of the sculpture. There are many formats available for RP printing. The most often used is STL and STP. Besides 3D scanning, you can also use 3D software to create digital mould. The most commonly use 3D software is Rhino, Zbrush and Maya.
After receiving the digital file from artist, we need to make necessary touch up on the work since there are always some piece missing during the scanning process.
After refinement of the 3D mold, we print out the sculpture. We make sure all the textured details of the sculpture are well kept. The printed pieces require our artisan to remove the imperfection and smooth its surface. To do that, we use very fine grain sand paper to sand the piece. The finished work is ready for making silicone rubber mold and wax work.
We make silicone rubber mold and the wax work ( for lost wax casting). We pay great attention to the make sure all the details of the wax is in perfect condition.
We use lost wax casting to cast bronze sculpture. After the bronze castings come out, we do the metal chase and weld pieces together, check out all the welding seam and smooth them. Bronze sculpture casting has been Tany Foundry***8217;s core business and we have a team of very skillful artisans to handle this.
After chasing work, we do patina on the bronze casting and seal wax. According to the artist***8217;s needs, we use dark brown for patina and the work is completed and they look really nice.
