Abstract:

According to some aspects, a system for identifying a printed object is provided. The system may include an imaging device configured to image a three-dimensional (3D) printed object and a processor coupled to the imaging device. The processor may be configured to receive information generated as a result of imaging the 3D printed object with the imaging device, identify a set of features for the 3D printed object using the received information, compare the set of features with multiple reference sets of features, each of the multiple reference sets of features being associated with a respective 3D object in a plurality of 3D objects, and identify, based at least in part on results of the comparison, a 3D object from the plurality of 3D objects that matches the 3D printed object.

Appl. No.:

13/798273

Inventors:

Edward K. Summers - Cambridge MA, US

Assignee:

Massachustts Institute of Technology - Cambridge MA

International Classification:

C02F 1/44

US Classification:

210640, 210180

Abstract:

Portions of a feed liquid are passed through respective condensers and liquid-liquid heat exchangers. The feed liquid is then heated and injected into a first feed-liquid containment chamber, where vapor from the feed is passed through a first gas-permeable membrane and directed into a first condenser, where the vapor is cooled by the feed liquid passing through the first condenser and condenses as it cools to produce a first liquid permeate. The first liquid permeate is passed through the first liquid-liquid heat exchanger where the first liquid permeate is cooled by the feed liquid passing therethrough. After the vapor is removed from the feed liquid in the first feed-liquid containment chamber, the remaining feed liquid from the first feed-liquid containment chamber is injected into a second feed-liquid containment chamber, where the process is repeated. The first liquid permeate from the first liquid liquid-liquid heat exchanger is combined with the second liquid permeate from the second condenser to form a combined liquid permeate; and the combined liquid permeate is passed through the second liquid-liquid heat exchanger where the combined liquid permeate is cooled by the feed liquid passing therethrough.
