3D Reverse Modeling and Rapid Prototyping of Complete Denture

An integrated method of reverse engineering and rapid prototyping technology to manufacture complete denture was presented in this paper. Firstly, geometrical surfaces of complete denture were measured by three-dimensional scanner and their point clouds were obtained. Then the point clouds de-noising processing was performed,data was filtered and reduced, the missing data was repaired and triangular surfaces splicing was realized in Geomagic software. 3D model of complete denture was reconstructed in Pro/E software, and the STL file was generated. Finally, the entity model was manufactured by rapid prototyping machine. Through this process the entity model of running-in-period complete denture was manufactured, which can reduce denture repairing time and contribute to health and medical research.

Study of 1 # direct methanol fuel cells for commercial market applications

In order to reduce the costs and improve the performances, conceptual design was proposed for a novel direct methanol fuel cells (DMFCs), named “1#DMFCs”, whose outside size and shape were ascertained by common 1# batteries. All basic parameters were gained from experiment datum. Inside dimension and structure were determined by calculating, admeasuring and devising elaborately. Three-dimensional model was devised through Pro/E, planar diagrammatic drawing was created by the software also, and detail drawing was drew with CAD further. Tubular membrane electrode assembly (MEA) without the fluid fields bipolar plates was used in this conceptual design, which was made up of titanium mesh anode layer, anode catalyst layer, Nafion membrane layer, cathode catalyst layer, gas diffusion layer and titanium mesh cathode layer in turn. This 1#DMFCs had perfect structure, including a one-way valve, a plug screw, a self-locking collecting water part et al. The MEA working area of 1#DMFCs was increased effectively by using of two tubular MEA, which would enhance the performance of the 1#DMFCs consequently.

Design and Analysis Of composite material bipolar plate pressure injection molding based on Pro/ENGNEER

A bipolar plate is one of the key components of a proton exchange membrane fuel cell. Development of a suitable processing method for bipolar plate is scientically. Three kinds of processing methods of composite bipolar plate are compared, and it thinks moulded method is the least investment shaping method. According to the shape and structure of the bipolar plate, pressure injection molding was designed by using three-dimensional design
