1. A solid freeform fabrication system comprising:
- a powdered build material deposited as a layer in a fabrication bin;
a binding powder deposited as a layer over said layer of powdered build material; and
an activating fluid that is selectively dispensed from an ejection head to activate said binding powder;
wherein activated binding powder then selectively binds said build material into a cross-section of an object being fabricated.
