For this project we needed to get the castings as small as possible and still fit the pre-made terminal block. I used my 3-D printer to cheaply and quickly make parts for the client’s verification. As you can see, the quality here is too poor to use in production parts or for patterns to make molds. (I later got a better 3-D printer that can make sand cast patterns that work after some hand finishing.) More expensive Shapeways printed brass was used to make the production patterns. This is about the largest part that can be produced using rubber molds and spin-casting with low melting point metals. |
