Comparative Study of Aluminum Alloy Casting obtained by Sand Casting Method and Additive Manufacturing Technology

摘要

In this research, a comparison between traditional sand casting technique and additive manufacturing technology with InkJet 3D Printing technique (3DP) was made, comparing the manufacturing time, cooling rate, dimensional deviation, surface quality, surface porosity and defects. In this way, feasibility and advantages of additive manufacturing was probed to be a good alternative to non-ferrous alloys sand casting.
