A direct-slicing approach might improve the accuracy and quality of small, complex parts produced with rapid prototyping technology. An application software based on direct slicing for rapid prototyping was used on the foundation of PowerSHAPE models. Lines, conic arcs and cubic bezier curves were adopted as the basic elements describing the direct-slicing contours. Moreover, a scheme to carry out subdivided software development was proposed. A picture (PIC) format file was selected as an interface for the slicing data, and a macro-AutoSection software, which collects the direct-slicing contour data of arbitrary complex computer-aided design models and provides power to produce the direct-slicing PIC files, was developed. On the above basis, an application software called PDSlice based on direct-slicing data processing was developed for the commercial selective laser sintering machine HRPS-III, which was made at the Huazhong University of Science and Technology (HUST), P. R. China. The major input and output interfaces as well as the PIC model reconstruction method of the PDSlice are described. Furthermore, a batch of direct-slicing polymer parts were successfully fabricated with the selective laser sintering machine. The application example shows that the accuracy and surface finish of three-dimensional complex curvature surface parts fabricated with the application software system based on a direct-slicing format were better than the application software system based on a stereolithography (STL) format.

The dental implant surgery results usually depend on dentists' clinical experiences and judgments. Most implant surgery utilizes the software to process pre-operation planning and simulation. Hence, this research intended to apply the rapid prototyping (RP) technique to build real mandible model for implant surgery simulation. Unlike other simple mandible RP models, vessels and nerves pathways are demonstrated in our model to help dentists to avoid false drillings on them. Besides, orientation pillars for surgical guide are included in the model. Moreover, for comparison's purpose, the platforms of placing indexing balls are also integrated. Computed tomography (CT) data of mandible were first converted to a CAD model with vessels, nerve, orientation pillars, and indexing platforms by a medical imaging processing software. RP technique was then utilized to obtain a real 3D model for pre-operation planning, surgical guide fabrication, and surgery simulation. The mandible model helped to drill holes on the traditional surgical guide by a 5-axis CNC drill press and it also drilled into the mandible model. Besides, the dentist simulated the drilling process in the dental implant surgery on the mandible model. Both drilled RP mandible models were CT-scanned and compared with the designed implant locations and angles. The errors are within acceptable region. Our approach has been successfully demonstrated in dental implant's pre-operation planning and simulation, which will help to increase the successful rate and safety of dental implant surgery.

This paper addresses the issue of creating physical prototypes of large-scale and complex assemblies using Rapid Prototyping technology. There are several technical challenges to overcome, both in software and the physical models. The challenges in software mainly stem from the fact that the mainstream CAD systems may not able to directly convert large-scale and complex assemblies to STL models. For the issues in the physical model, some of the components of the scaled assemblies are too small to fabricate using RP or too weak to produce viable prototypes for intended purposes. In addition, the paper presents information regarding support of relative motion between components in the RP model, which is desirable for demonstrating kinematics of the system. The paper proposes a systematic approach that addresses these issues and realizes quality physical prototypes serving intended purposes. Practical examples are employed in this paper, including a Formula SAE race car assembly that is used as the principle example for this study. [ABSTRACT FROM AUTHOR]

Leading MIS executives and academicians have identified systems development as one of the most critical issues of the 1980s. Their concerns include providing user accessibility to stored information, reducing development cost and delay, increasing developer productivity, and increasing MIS's impact on organizational growth, productivity, and profitability. Among the number of proposed alternative approaches to traditional systems development, prototyping is mentioned frequently. Prototyping is routine in hardware development but not software. The authors review published references to prototyping and related concepts and synthesize a process model for information systems. In this model, resource requirements are enumerated and discussed. The article includes an analysis of the economics of prototyping, and a brief discussion of several examples. Prototyping for information systems development addresses today's critical issues; it will no doubt raise a new set of research questions for tomorrow. [ABSTRACT FROM AUTHOR]

A prototyping and simulation tool that supports the development of distributed programs is described. This tool, called Jems, forms a part of Jade, a distributed software prototyping environment. The Jade environment provides tools for the design, implementation, debugging, testing, maintenance, and performance analysis of distributed, concurrent programs. Novel features of Jade include the support of: multi-lingual distributed programs; flexible monitoring of inter-process communication; multiple views into executing programs via a window system; graphical animation of executing programs; and the prototyping of distributed software.

A methodology for the design of artifacts used in software error compensation of rapid prototyping (RP) machines is presented. In software error compensation, an artifact is frequently utilized for measuring parametric errors of the machine axes. In the past, different artifacts have been used and designed in an ad hoc way. To date, no method is available to evaluate the design of an artifact based on its effect on the precision of the fitted models estimated using the artifact. This paper proposes a method to evaluate and improve the design of an artifact using design of experiments (DOE) techniques and numerical optimization. As demonstrated by the results, a D-optimality criterion optimized using simulated annealing techniques can be used to evaluate and improve the design of an artifact so that the components of the volumetric error are predicted more precisely, with the benefit of better error compensation over repeated use of the error models. Although in this paper the concept is only demonstrated for the SLA 250 RP machine, it can be applied to the design of any artifact used for machine error compensation. [ABSTRACT FROM AUTHOR]

Improvement of part surface quality and geometric accuracy by modifying slicing procedure in RP has been a major concern. Reduction in build time and enhancement of part surface quality are two factors which contradict with each other as decreasing build time detracts part quality because of staircase effect. There have been a number of attempts to tackle this problem by using adaptive slicing procedures in which slice thickness is determined by the local part geometry and RP machine specifications. A geometrical parameter known as cusp height is limited to a pre-specified value in various existing adaptive slicing procedures, which is defined for rectangular or sloping edge profiles only. In another approach, relative change in areas of successive slices have been considered as criterion to adaptively slice CAD models but this method has limitation as local geometry of part is not taken into consideration. Therefore, in the present work, a slicing procedure is presented in which statistical surface roughness model developed by Pandey and his group  for SLS prototypes has been used as a key to slice the tessellated CAD model adaptively. The adaptive slicing system is implemented as Graphic User Interface in MATLAB-7. The capabilities of developed adaptive slicing system have been demonstrated by case studies. [ABSTRACT FROM AUTHOR]
