Quality Improvement of Sand Castings through Implementation of 3D-Printing Technology
Traditional foundry practices are found less beneficial to fabricate the cast patterns because of high manufacturing cost and lead time. Generally, the patterns are made of wood or metal. Complex and thin shapes are difficult to be done in wood patterns. If wood is replaced by metal patterns, then the cost would increase. Wood patterns are usually made manually, and high skilled labor is required. If some part of the work is carried out by machining operations, the technology available for machining woodwork is limited. To overcome these difficulties, the pattern material is replaced from wood to ABS (Acrylonitrile Butadiene Styrene). The recent development of the FDM (Fused Deposition Modeling) technique in 3D-printing technology is used for making ABS patterns instead of conventional. Using ABS material, it was found that any complex shapes of patterns can be made easily thereby improving pattern life, better yield, withstanding of ramming forces, anti-resistant to chemical reactions, achieving precise geometrical shapes, and surface texture with high dimensional accuracy along-with lead time and cost. Results show that the combination of 3D-printing technique and ABS as input material for cast pattern would help to face the present challenges observed within casting industries.
