A method and apparatus for dispensing and distributing a powder is disclosed that uses a rotary dispenser to dispense the powder by gravity onto a movable platen, the platen being movable to a position adjacent to a build bed where the powder can be distributed across the build bed using a spreader. The method and apparatus are also suited to dispensing of a plurality of powders used in build beds for solid free-form fabrication and three-dimensional printing. It is preferred that a powder contacting surface of the apparatus be coated with a coating selected from the group consisting of: an anodized finish, a hardcoat anodized finish, siloxane, baked enamel, electroplated enamel, electroless nickel, coated elastomer, laminated elastomer, dipped latex, sprayed latex, polyvinyl chloride, nylon, polytetrafluoroethylene, polyurethane, an epoxy resin, or a polyester.

Apparatus, systems and methods for use in three-dimensional printing are shown and described. Various embodiments of the invention allow for more precise and controlled delivery of heat to achieve interlayer drying; isolation of the working region from the outside for reasons of cleanliness and in connection with the vapors of organic solvents; better control of the temperature of the working region; better accuracy in the flowrates of binder fluid dispensed; matching of delivered flowrates for multiple dispensers; verification of delivered flowrate or drops; provision for easier changeover of the machine from one powder to another; cleanability; and other needs.
