Rapid
Tooling Techniques
Direct
Investment Casting
Utilizing solid and quick cast resin models
produced by the following process: Stereolithography
, Selective Laser Sintering , Laminated
Object Manufacturing, and 3D Printing investment
casting patterns can be produced. The resin
model is used directly as an expendable
pattern and is ultimately burned rather
than melted away, as is done with the wax
pattern.
Lead times for prototype
investment castings are typically 3-4 weeks
after receipt of the resin model. The process
is capable of producing intricate parts
ranging in size from 1" to over 36".
