First Claim
Patent Images
1. A solid freeform fabrication system for producing a three-dimensional object, comprising:
- a dispensing system adapted to separately dispense build material and support material, wherein the build material and the support material are adapted to contact one another at an interface after being dispensed; and
a curing system adapted to harden the build material after being dispensed but before the support material is dispensed, wherein mixing between the build material and the support material is inhibited at the interface.

Abstract
The present invention is drawn to a solid freeform fabrication system for producing a three-dimensional object. The system can include a dispensing system and a curing system. The dispensing system can be adapted to separately dispense build material and support material, wherein the build material and the support material are adapted to contact one another at an interface after being dispensed. The curing system can be adapted to harden the build material after being dispensed but before the support material is dispensed, wherein mixing between the build material and the support material is inhibited at the interface.
