Modeling costs can be cut

To produce large, dimensionally accurate master models at one-third the cost of using conventional materials, Visioneering, Inc. is using a machinable, seamless modeling paste. The RP 4503 R/H epoxy paste, supplied by Ciba Specialty Chemicals, is an easy-to-extrude, fast-curing compound that exhibits low shrinkage to produce 6.1-m (20-ft) long and larger models that can hold tolerances to ±0.13 mm (±0.005 in).
