Polymers for additive manufacturing

Porous and microporous parts prepared by additive manufacturing as disclosed herein are useful in medical and non-medical applications. The parts are prepared from a composition containing both a solvent soluble component and a solvent insoluble component. After a part is printed by an additive manufacturing process it is exposed to solvent to extract solvent soluble component away from the printed part, resulting in a part having surface cavities.

MOBILE COMMERCE PLATFORMS AND ASSOCIATED SYSTEMS AND METHODS FOR CONVERTING CONSUMER COINS, CASH, AND/OR OTHER FORMS OF VALUE FOR USE WITH SAME
20180000594 · 2018-01-04 ·

Systems and methods for converting consumer coins, cash, and/or other forms of value for use with mobile commerce platforms implemented on, for example, smart phones, PDAs, and other mobile devices. In one embodiment, a method for implementing a mobile commerce account on a mobile device includes receiving coins and/or other funds from a user at a consumer-operated kiosk. The method can further include counting the coins and/or other funds to determine a value, and then communicating at least a portion of the value from the kiosk to the hand-held mobile device for deposit in the mobile commerce account.

Method for Solid Freeform Fabrication

The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. The deposited powder bed is heated to about 50° C. to about 170° C. Then, a solution of activating agent is printed on the powder bed in a predetermined pattern, and a stimulus is applied converting the prepolymer to the final polymer. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.
