Augmented three-dimensional (3D) printing systems and methods for constructing and mineralizing a hydrogel structure with defined geometry are disclosed. One example embodiment is a system for three-dimensional printing and mineralizing a polymer. The system includes a three-dimensional printer unit with a syringe extruder, a fluid delivery system operatively coupled to the three-dimensional printer unit, and a control unit. The control unit is operatively coupled to the three-dimensional printer unit and fluid delivery system, and is configured to (i) cause the three-dimensional printer unit to print a portion of a three-dimensional polymer object, (ii) cause the fluid delivery system to flush the portion of the three-dimensional polymer object with a fluid to mineralize the portion of the three-dimensional polymer object, and (iii) cause the three-dimensional printer unit to print a subsequent portion of the three-dimensional polymer object. Applications of embodiments include manufacturing of tooth, bone, and other biomaterial articles.

A food processor including a reversible motor disposed in a base for generating a rotational force, a processor container removably attached to the base, a spindle rotated by the reversible motor when energized, and a slicing disc rotatably coupled to the spindle, the slicing disc having a radially extending slicing blade formed on one side thereof configured to perform a slicing operation and a plurality radially extending shredding blades disposed oppositely to the slicing blade on the slicing disc configured to perform a shredding operation. The slicing disc is automatically rotated in a first direction by the motor when the first and third discrete positions are selected on a slice selector disc corresponding to the slicing and dicing operations and automatically rotated in a second direction by the motor when the second discrete position is selected on the slice selector disc corresponding to the shredding operation.
