Issues in Process Planning for Laser Chemical Vapor Deposition
(2002)Laser Chemical Vapor Deposition (LCVD) is a promising rapid prototyping and manufacturing process that deposits metals and ceramics by local heating of a substrate with a laser. Even though many LCVD process planning ... -
Application of Laser-Based Additive Manufacturing to Production of Tools for Friction Stir Welding
(2002)This paper presents a feasibility study of application of laser-based additive manufacturing to production of tools for friction-stir welding (FSW) of materials. The design and rapid manufacturing of powerful tools has ... -
Visualization of Surface Accuracy for Virtual Prototyping
(2002)This paper introduces a virtual prototyping (VP) system that simulates a RP process to produce a virtual prototype of a product, which facilitates visual study of the surface quality of the physical prototype that the ... -
Stereolithography Process Resolution
(2002)To build smaller parts in StereoLithography (SL) and detect some build errors before fabrication, a good understanding of process resolution is needed. A categorization of resolution factors into process-inherent and ... -
Laser Aided Part Repair-A Review
(2002)Laser aided part-repair is an emerging trend that has great potential for future industrial applications. Part-repair technologies are currently used in repairing military and civilian equipment. The focus of this paper ... -
Finite Element Thermal Analysis of Three Dimensionally Printed (3DP™) Metal Matrix Composites
(2002)Three Dimensional Printing, 3DP™, is under development for the production of metal composites through solid freeform fabrication of a skeleton, followed by sintering and then infiltration of a second, lower melting metal. ... -
A Study on Effects of Process Parameters in Rapid Freeze Prototyping
(2002)Rapid Freeze Prototyping (RFP) is a relatively new solid freeform fabrication process, which builds a three-dimensional part according to a CAD model by depositing and freezing water droplets layer by layer. A study on ... -
The Study of On-Line Waste Material Removal Procedures for Bridge Laminated Object Manufacturing (LOM) Process
(2002)Focusing on the drawbacks inhered in the laminated object manufacturing (LOM), a new Bridge-LOM process and its associated building algorithm are proposed in this paper. The proposed Bridge-LOM process starts with the ... -
The SLS Characteristics of 1.8wt% Clay Nanoparticle/Nylon 6 Composite
(2002)Selective laser sintering (SLS) characteristics of clay nanoparticle/Nylon 6 composite were studied for the applications in Rapid Prototyping and Manufacturing (RP&M). Differences of sintering behaviors between the ... -
An Investigation of the Control Parameters for Aluminum 3003 under Ultrasonic Consolidation
(2002)In this article, we investigate an innovative solid-state welding technique called Ultrasonic Consolidation (UC) that is being developed as a freeform process for the layered fabrication of aluminium tapes. UC involves ... -
The Development of an Integrated Graphical SLS Process Control Interface
(2002)This paper presents the systematic development of a man/machine interface for Selective Laser Sintering. The interface developed integrates geometry design, process data/code generation, power control and communication ... -
Heat Transfer Manipulation for Precision Droplet Manufacturing: Simulation and Experiment
(2002)The solid free-form fabrication (SFF) of arbitrary metallic components is accomplished with controlled deposition of nano-liter molten droplets generated by capillary stream break-up and deposited at rates on the order ... -
Rapid Prototyping (through SLS) as Visualisation Aids for Architectural Use
(2002)The Cambridge International Dictionary of English, explains the word "Design" as a "pattern used to decorate something". Whilst this very narrow-minded definition can spark a debate on the meaning of design, it does ... -
Adhesive Bonding of Sheet for Laminated Metal Tooling
(2002)There exists a significant body of work on metal laminate tooling built by the “cut-stack-bond” approach; however, automation with this method is difficult. Building laminations by "stack-bond-cut" sequence, on the other ... -
Heterogeneous Material Modeling with Distance Fields
(2002)We propose a universal approach to the outstanding problem of computer modeling of continuously varying distributions of material properties satisfying prescribed material quantities and rates on a finite collection of ... -
Investigation Into the Mechanical Properties of Rapid Manufacturing Materials
(2002)During the past few years, there has been a move to convert Rapid Prototyping (RP) processes into Rapid Manufacturing (RM) machines to produce end-use parts for different industries. However, in order to make Rapid ... -
An Integrated Approach to Finish Machining of RP Parts
(2002)An integrated approach to finish machining of RP parts and tools has been developed at the University of Rhode Island. Pre-processing operations, including surface offsets to add machining stock, and post-processing ... -
Evaluation of PROMETAL Technique for Application to Dies for Short Run Forgings
(2002)Manufacturing of hot forging dies required several steps such as acquisition of material block, shaping it for machining, rough machining the cavity, heat treating, finish machining, grinding and polishing. This process ... -
Prediction of Microstructure in Laser Deposition of Titanium Alloys
(2002)Laser deposition of titanium alloys is under consideration for aerospace applications, and offers significant increases in efficiency and flexibility compared to conventional manufacturing methods. However, its ultimate ...
