MELT FLOW ANALYSIS OF ABS IN FUSED DEPOSITION MODELLING PROCESS

摘要

This paper presents a numerical study of melt flow behaviour of ABS plastic through the melt flow tube of the liquefier head of the Fused Deposition Modelling (FDM) rapid prototyping process using the finite element analysis. Main flow parameters including temperature, velocity and pressure drop have been investigated. Liquefier head of FDM machine has been modelled parametrically and the effects of physical modifications including nozzle angle variation on the melt flow parameters have been investigated accordingly. Results provide promising information on flow behaviour of new ABS based composites for processing in the FDM system to fabricate new products.
