Abstract Rapid Prototyping (RP) technology has found applications in medicine. Model produced using rapid prototyping technique can enhance interpretation, visualization and physical evaluation, and is useful to pre-surgical operation. This paper presents an integrated reverse engineering system for biomedical application. The configuration of this integrated system consists of hardware and software layouts. The components within the hardware layout are completed except the fiber optic link. The components of the software layout are completed. The reverse engineering system using rapid prototyping technique is applied in the case studies of nose prosthesis and ear prosthesis.

Abstract Three-dimensional data acquisition, surface registration and integration as well as subsequent rapid manufacturing are important processes in reverse engineering. This paper describes a reverse engineering system for rapid manufacturing of complex objects. The system consists of a three-dimensional digitizer (3D Optical Digitizing System), surface reconstruction software and a rapid prototyping machine. The surface reconstruction software has three major components: 1) range view registration by an iterative closed-form solution, which uses Binary Space Partitioning (BSP) tree to accelerate computation; 2) range surface integration by reconstructing an implicit function to update the volumetric grid; and 3) iso-surface extraction by a Marching Cubes algorithm. The surface reconstruction software exports models in STL format for rapid prototyping. A FDM 2000 machine is used to manufacture products. Examples are included to illustrate the systems and the methods.

Emotion Theory

Murray Smith’s proposal in Film, Art, and the Third Culture for a naturalized aesthetics is of interest to both film theorists and psychologists: for the former, it helps to elucidate how films work; for the latter, it provides concrete application cases of psychological theories. However, there are reasons for believing that the theory of emotions that Smith has adopted from psychology to ground his case studies—an extended version of basic emotions theory—is less well supported than he suggests. The available empirical evidence seems more compatible with the assumption that the different emotions are outputs of a single, integrated system.

Npd Performance

This study extends the new product development (NPD) to a new field; Market Driving Digital New Product Development Method is addressed in this paper, which is based on reverse engineering and rapid prototyping technology. This study finds that the higher the effort on marketing-R&D process, the less possible it might encounter risk. Thus, a better NPD performance can be achieved by market driving Digital NPD method (MDDNPD).A case study of All-Terrain Vehicle (ATV) is used to illustrate the new method. We believe that the proposed methodology will have a positive impact on the future new product development.

Medical Imagery

In the last years, cardiovascular diagnosis, surgical planning and intervention have taken advantages from 3D modelling and rapid prototyping techniques. The starting data for the whole process is represented by medical imagery, in particular, but not exclusively, computed tomography (CT) or multi-slice CT (MCT) and magnetic resonance imaging (MRI). On the medical imagery, regions of interest, i.e. heart chambers, valves, aorta, coronary vessels, etc., are segmented and converted into 3D models, which can be finally converted in physical replicas through 3D printing procedure. In this work, an overview on modern approaches for automatic and semiautomatic segmentation of medical imagery for 3D surface model generation is provided. The issue of accuracy check of surface models is also addressed, together with the critical aspects of converting digital models into physical replicas through 3D printing techniques. A patient-specific 3D modelling and printing procedure (Figure 1), for surgical planning in case of complex heart diseases was developed. The procedure was applied to two case studies, for which MCT scans of the chest are available. In the article, a detailed description on the implemented patient-specific modelling procedure is provided, along with a general discussion on the potentiality and future developments of personalized 3D modelling and printing for surgical planning and surgeons practice.

Optimization Efficiency

The structure of Microbial Fuel Cell (MFC) reactor was analyzed and improved by Reverse Engineering (RE) and Rapid Prototyping (RP) technology. Points cloud data of MFC reactor was accessed by hand-held laser scanner. The space surface and entity model were reconstructed accurately, and the structure of the reactor was optimized based on Imageware and Solidworks software. The reactor model was manufactured by RP machine. The optimization efficiency of MFC reactor was improved based on the combination of RE and RP, which has a good reference value for the development of MFC technology and products.
