Additive technologies can be utilized for investment casting patterns.Additive technologies in investment casting involves 3D printing of the wax pattern wherein the traditional method uses an injection mold manufactured using subtractive technologyto produce the wax pattern.Rapid 3D Technologies located at Ganapathy, Coimbatore, India is engaged in working with various foundries to develop such 3D printed wax patterns using special wax like plastic material. One of the modern applications for additive casting patterns is creating environmentally friendly and socially conscious jewelry. On the other end of the spectrum, applications for casting patterns have produced products that contain a variety of metals and can weigh several hundred pounds. Additivelygenerated patterns can be created from thermoplastic extrusion using wax, plastics, 3D printing and inkjet technology that utilize wax-like plastics. These types of materials require being melted or burned very cleanly from the investment.
