Abstract
A system and method for generating investment casting patterns by 3D printing. CAD software is used to generate a hollow 3D model of a solid 3D model of a desired pattern. The pattern is generated by a 3D printer which prints the exterior of the pattern in pattern wax and the interior in support wax.
Claims19
A method for creating an investment casting pattern comprising:
- acquiring at least one solid 3-dimensional (3D) model of a desired investment casting pattern by an associated computer aided drafting (CAD) device, wherein the solid 3D model is acquired by CAD software on the associated CAD device;
- processing the solid 3D model with the CAD software to generate a 3D hollow model of the desired investment casting pattern, the 3D hollow pattern comprising an exterior surface of a particular thickness surrounding a substantially hollow interior;
- transferring the 3D hollow model to an associated 3D printing device;
- and
- generating, by the associated 3D printing device upon receipt of the 3D hollow model, the desired investment casting pattern by printing the exterior of the investment casting pattern in a first material and printing the substantially hollow interior of the investment casting pattern with a second material.

A system for creating an investment casting pattern comprising:
- a first material;
- a second material;
- a computer aided design (CAD) device including CAD software;
- and
- at least one 3-dimensional (3D) printing device operatively coupled to the CAD device, the 3D printing device being configured to receive the first material and the second material,
- wherein the CAD software is configured to acquire at least one solid 3D model of a desired investment casting pattern and process the solid 3D model to generate a 3D hollow model of the desired investment casting pattern having an exterior surface of a particular thickness surrounding a substantially hollow interior, and
- wherein upon receipt of the 3D hollow model, the 3D printing device is configured to generate the desired investment casting pattern by printing the exterior of the investment casting pattern in the first material and the substantially hollow interior of the investment casting pattern in the second material.
