Automating Sheet-Based Fabrication: The Conveyed-Adherent Process
(1996)A new automated fabrication technology is described which breaks the fabrication process into spatially separate layer-formation and layer-bonding stages. The technique uses sheet material on a substrate as feedstock and ... -
Biocompatibility of SLS-Formed Calcium Phosphate Implants
(1996)A method for fabricating artificial calcium phosphate bone implants by the Selective Laser Sintering (SLS) process has been developed that can fabricate complex and delicate calcium phosphate bone facsimiles from a variety ... -
Curing Behavior of Ceramic Resin for Stereolithography
(1996)Ceramic green bodies have been created with stereolithography methods by using ultraviolet curable suspension of ceramic powders, a "ceramic resin", on a Stereolithography Apparatus (SLA). A minivat system with mini-recoater ... -
"Curved-Layer" Laminated Object Manufacturing
(1996)A process where a freeform solid object is built by bonding cut layers of material together is called a Laminated Object Manufacturing process. Until today, all ofthe LOM processes utilized straight forward planar ... -
Development ofDirect SLS Processing for Production ofCermet Composite Turbine Sealing Components - Part I
(1996)This paper presents the development to date of SLS (selective laser sintering) technologies for production of cermet composite turbine sealing components, the particular application being an abrasive blade tip. The ... -
Direct Feedback Control of Gas-Phase Laser-Induced Deposition
(1996)Three-dimensional laser Chemical vapor deposition (3D-LCVD) or SALD, was used to prototype metallic and ceramic microstructures. Iron, nickel, and steel metal forms were grown from organic and halogen based precursors. ... -
Direct Manufacturing of Metal Prototypes and Prototype Tools
(1996)Due to the limited mechanical characteristics of the materials which can currently be processed using industrially available Rapid Prototyping machines, a lot of research is focused on the development of techniques which ... -
EDM Tooling by Solid Freeform Fabrication & Electroplating Techniques
(1996)The term "Rapid Tooling" refers to the rapid creation of tools in much the same way as Solid Freeform Fabrication (SFF) means the rapid creation of models. This revolutionary approach offers both designers and manufacturers ... -
Extraction of Fault Patterns on SLS Part Surfaces Using the Karhunen-Loeve Transform
(1996)To gain a thorough understanding of the fault mechanisms in SLS machines, we decompose SLS profile signals into independent features using a novel tool called Karhunen-Loeve (KL) transform. These individual features can ... -
Fabrication of Parts Containing Small Features using Stereolithography
(1996)The StereoLithography (SL) process has benefited from many advances in the last four to five years. These include new resins with reduced shrinkage and curl distortion, enhanced software, and improved scanning techniques. ... -
Fast Production of Technical Prototypes Using Direct Laser Sintering of Metals and Foundry Sand
(1996)Currently most RP-Parts are used for visualisation, assembly checks and some functional testing. The next stage between these functional prototypes and the pre-series is technical prototypes, which are used for final ... -
Feature Extraction From Tessellated And Sliced Data in Layered Manufacturing
(1996)When parts are built in layers, the cross sectional area of each layer has to be defined and filled with a pattern of vectors. This filling process is called hatching and the vectors defme the hatch pattern. To accurately ... -
Filament Feed Materials for Fused Deposition Processing of Ceramics and Metals
(1996)Fused Deposition of Ceramics (FDC) and Metals (FDMet) are SFF techniques, based on commercial FDMTM technology, for fabrication of ceramic and metal components. The FD processes use feed material in the form of filaments ... -
Finite Element Analysis and Strain Gauging of the Stereolithography/Investment Casting System
(1996)Many metal parts have been produced from stereolithography (SL) models via the investment casting route. However, it is still not possible for every foundry to directly use SL models as thermally expendable patterns and ... -
Finite Element Analysis of Curl Development in the Selective Laser Sintering Process
(1996)The work reported within this paper is concerned with the development of analytical procedures which will allow the accuracy of parts generated by selective laser sintering to be predicted. One source of inaccuracy is ... -
Forced Convection in a Polymeric Powders
(1996)In a Selective Laser Sintering (SLS) powder bed, thermal transfer occurs through multiple modes. Forced convection through the powder, or downdraft, has recently been implemented in SLS machines in an effort to enhance ...
