Investment Casting with Additive Manufacturing

Investment casting, also known as lost-wax casting, is a precision metal casting process that uses a hollow, sacrificial mold to produce high-precision metal parts. With the integration of additive manufacturing techniques, investment casting has become even more efficient and versatile. The process starts with a 3D printed wax pattern. A slurry then coats the wax pattern to form a sacrificial mold. Over time, the slurry hardens into a shell which enables users to burn the wax. The final mold can then be filled with molten metal. The end result is a high-quality metal part with numerous benefits, including improved accuracy and reduced lead times. Here are a few leading benefits to investment casting with additive manufacturing:

  • Cost-effectiveness: 3D printing enables the production of customized casting patterns at a lower cost compared to traditional methods.
  • Speed: 3D printing speeds up the production of casting patterns, leading to a faster turnaround time.
  • Versatility: 3D printing allows for the creation of complex shapes and geometries that may not be achievable with traditional methods.
  • Weight Reduction: 3D printing enables lighter weight casting patterns, offering benefits in specific applications.
  • Customization: 3D printing enables the production of casting patterns that tailor towards specific applications.
  • Reduced Waste: Unlike traditional methods, 3D printing generates little to no waste.
  • Improved Performance: 3D printing allows for the design of casting patterns with improved dimensional accuracy and surface finish. This results in improved performance of the final cast parts.

Investment casting with additive manufacturing offers a range of benefits. Each of which makes additive manufacturing a more cost-effective, faster, and versatile process compared to traditional metal casting methods. The process enables the creation of high-precision metal parts with complex shapes, lighter weight, custom designs, reduced waste, and improved performance. The incorporation of 3D printing technology in investment casting has revolutionized the metal casting industry, offering new possibilities for manufacturers.
