  • Bridging additive manufacturing and sand casting

    · Although additive manufacturing technology is available for the direct fabrication of metal parts, the process is still in a juvenile state compared to older metal fabrication methods such as sand casting Therefore, limited standards are available stipulating the use of additivelymanufactured parts in critical service conditions such as extreme environments or safety components HoweverAdditive manufacturing is a serious alternative for the metal casting process 3D printing enables printing of patterns direct without making moulds This reduces the process steps Mould costs are among the highest in the total cost structureAdditive Manufacturing for Sand Casting StratnelThe production of foundry tooling has been adopting additive manufacturing (AM) as a fabrication method Conventional fused filament fabrication is the most common AM production process but is typically limited in types of materials available These materials (such as PLA and ABS) have relatively poor abrasion and chemical resistance This presentation will discuss and compare severalSand Casting and Additive Manufacturing Expertise (On
