Abstract:
The conventional Sand casting requires storage of pattern so foundries can again pack sand around them to make a new mold when in batch production or the order is placed again. They have to fabricate according to the geometrical desgin, have to keep the fabricated part in inventory. The foundry is actually paying to have them warehoused. It also requires a great skill and a lot of effort and time is wasted for making a pattern and small mistakes results into complete loss of pattern and it has to be made again. 3D printing system for sandcasting will put an end to the need for such storage and fabrication time will be reduced. It fully automates the simultaneous creation of sand molds of the patterns out of sand. The inner geometries, risers and runners etc. are printed simultaneously. This project can be used for printing 3D mold structures with the use of proper feed materials. It can innovate the casting industry of Pakistan by improving the process on a large scale
