Tensile Mechanical Behaviour of Multi-Polymer Sandwich Structures via Fused Deposition Modelling

modelling of the indentation behaviour of thermoplastic honeycomb sandwich panels

thermoplastic honeycombs based on polypropylene are one of the latest types of cores used in sandwich structures. up to now there have been few experimental and modelling studies on the mechanical behaviour of sandwich structures with thermoplastic cores. in this paper, by considering the similar properties of foams and thermoplastic honeycombs, attempts are made to model the static indentation...

Study of Dynamic Mechanical Properties of Fused Deposition Modelling Processed Ultem Material

Fused Deposition Modelling (FDM), a renowned Rapid Prototyping (RP) process, has been successfully implemented in several industries to fabricate concept models and prototypes for rapid manufacturing. This study furnishes terse notes about the material damping properties of FDM made ULTEM samples considering the effect of FDM process parameters. Dynamic Mechanical Analysis (DMA) is carried out ...

Dynamic Mechanical Properties of ABS Material Processed by Fused Deposition Modelling

This paper presents a study of dynamic mechanical properties of Fused Deposition Modelling (FDM) rapid prototyping processed material Acrylonitrile butadiene styrene (ABS). It involves the measurement of modulus and damping properties of the material as it is deformed under periodic stress. In this study, frequency sweep is performed in DMA 2980 equipment to determine modulus, damping and visco...

Mechanical Properties Optimization of Poly-Ether-Ether-Ketone via Fused Deposition Modeling

Compared to the common selective laser sintering (SLS) manufacturing method, fused deposition modeling (FDM) seems to be an economical and efficient three-dimensional (3D) printing method for high temperature polymer materials in medical applications. In this work, a customized FDM system was developed for polyether-ether-ketone (PEEK) materials printing. The effects of printing speed, layer th...
