Design Advancement Rapid Design Advancement Rapid Tooling Tooling DART Introduction With great pleasure, RPC Research presents an MSOE-born Rapid-Tooling Process called Design Advancement Rapid Tooling (DART). A few years back, the RPC Rapid Tooling Committee advised RPC Research to proceed with evaluating the potential of DART for injection molding applications. Since this “call to action” RPC research has conducted over 100 experiments and tested 10 DART molds. We have recently concluded that DART is a competitive approach to rapid tooling. DART Objective Produce DART injection molded parts in four days (or less) with minimal human intervention , +/-0.0005inches/inch accuracy , 25% of traditional tooling cost , and quantities of 200 to 2,000 (50 in 4 days) . DART Process The indirect process starts with a 3D pattern and after several proprietary steps, a durable Epoxy Matrix Composite Mold is produced. Characteristics of DART include: •Very fast, from CAD model of part to injection molded part in as little as 4-5 days (currently 2-6 weeks) •Scalable, could potentially be scaled to the size of a car door or larger (current size is 4x4 inch mold inserts) •Accurate, reproduces the pattern with little to no accuracy loss (target +/- 0.0005 in/inch) •High aspect ratios (tall, thin core features survive molding conditions) •Prototype to short run quantities For further information, please contact: Milwaukee School of Engineering Rapid Prototyping Center 1025 N.
