Rapid Prototyping (RP) is the relatively high-speed fabrication of physical
parts from Computer Aided Design (CAD) data and is used in numerous
industries, from product development to surgical implant manufacture. All
conventional RP systems employ a horizontal virtual plane slicing process to
process CAD data in order to produce layered bottom-up build pathways to
perform RP. A novel Vertical Machining Centre (VMC) add-on hot-melt
deposition system for performing RP has been developed which enables
investigation of both layered and non-layered RP.
Neil Sewell has recently
completed a PhD investigating the feasibility of multi-axis rapid
prototyping using virtual machining centres. A preliminary paper Algorithms for multi-axis rapid
prototyping gives some details.
The picture at the top shows a simulation of a sphere constructed by
wrapping material (often a glue), and the photograph below shows a bent pipe
constructed using the multi-axis technique.
