after making the Autodesk Inventor design and make the cut with CNC shopbot, I have positive and negative mold |
I chose fabrics to go with the mold, burlap , expoxic resin we sourced locally: Pox Bak. It is mainly used in electric and electronic devices, but it would have to do. It is composed of a resin and a catalyst, and in order to be used it has to be prepared, the parts being added in a 2:1 ratio. |
I covered the first mold with Vaseline to facilitate the removal of the fabric, as later |
also it covers the first mold plastic |
calculating appropriate proportions 2: 1, using a balance |
I cover the entire mold with the mixture |
finally I put a plastic layer and cover with the positive mold, with the help of presses |
The final result is shown in the picture, in some places good results are not obtained, due to poor distribution of the material, a recommendation would be to use a brush to evenly distribute the material ( DOWNLOAD_design files ) Autodesk inventor |
