...Wanlong Wang; James G. Conley; Henry W. Stoll It is now possible to generate tooling for near net shape manufacturing processes directly from a CAD database by using computer numerical control (CNC) machining or a variety of rapid prototyping (RP) processes. These methods are widely referred...

...B.G. Bryden; I.R. Pashby This paper outlines a method of sequentially joining steel laminations together using a high strength brazed joint to produce laminated tools. Individual joints were produced by using a heated platen rather than a furnace. Lap shear test samples were used to evaluate...

...N.P. Karapatis; J.P.S. van Griethuysen; R. Glardon Rapid prototyping technologies are now evolving toward rapid tooling. The reasons for this extension are found in the need to further reduce the time‐to‐market by shortening not only the development phase, but also the industrialization phase...

...Sadegh Rahmati; Philip Dickens Explains that stereolithography (SL) can greatly reduce initial tooling costs, thus making prototyping and small production runs economically feasible. Describes how epoxy resin SL5170 and Zeneca filled resin are used to build SL injection moulding tools. Different...

... Limited 1997 Modelling Prototyping Tooling Selective laser sintering (SLS) is a leading process in the new field of solid freeform fabrication (SFF)[ 1 ]. SLS is an additive process that produces parts directly from a CAD model by melting, or sintering layers of a powder together...

...Lena Apelskog Killander Describes and evaluates a laser‐sintering based method for prototype tooling epoxy‐infiltrated, laser‐sintered inserts. The niche aimed at is prototype tooling for up to a hundred parts. The results are promising. The method is rather fast where two inserts (one tool) can...

... of the EDM die sinking process and expanding the role of RP in the production environment. Thin coated stereolithography (SL) models have been used to erode hardened tool steel to a depth of 4mm. Machining efficiency of these copper coated RP models is not comparable to that of conventional machined solid...

... generating. Pays particular attention to the selection of suitable materials. Discusses the application of these techniques to the manufacture of metal tools. Two different forms of energy input were selected as examples on which to base the investigation of the sintering characteristics of this material...
