For this sand casting project, we designed and 3D printed a pattern and then used it to make a sand casted jewelry holder. The 3D-pattern came out very nicely. When we first began the sand casting process, we packed the drag of our mold and found that some portions had indentures that had to be packed a lot more tightly than other places in the mold. After learning this, we took more care and attempted to apply more pressure to pack the sand for the cope. This resulted in a smoother finish for the mold. We also discovered that we had to be very careful when molding the sprue. We cleaned the edges of the cope and drag to ensure sand would not interfere with the connection of the two and to prevent molten metal from flowing between the cope and drag. The large draft that we implemented made removing the mold from the packed sand very easy.
