Abstract
For particular applications such as automotive and aerospace engineering, polymer gears have unique advantages over metal gears, such as: low cost and weight; high efficiency; quietness of operation; functioning without external lubrication; etc. The characteristics of wear and thermal behaviour of injection moulded gears have previously been studied [1], however, additive manufacturing (AM) and 3D printing processes have become increasingly popular for production of polymer components. It is generally understood that 3D printing is cost effective if production volumes are below 1000 units in comparison with plastic injection moulding [2]. The technology has been applied in wide range of industries, including the automotive, aerospace, medical and architectural industries [3]. The nature of 3D printing means that the process is inherently linked to the materials used and each 3D printing technology has a subset of materials that it is compatible with. For Fused Deposition Modelling (FDM) for instance there are many different materials available on the market including polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), polycarbonate (PC), nylon and many others [4]. Due to the increased interest in 3D printing there is an increasing amount of research regarding the direct mechanical properties and thermal properties of 3D printed materials and their modification. Leigh et al. [5] introduced a low-cost conductive composite material for 3D printing of electronic sensosr. Christ et al. [6] increased the elastic strain of polyurethane through addition of multi wall carbon nanotubes. Blok et al. [7] claimed that adding continuous fibers could further increasing the tensile strength compared with carbon fibre nylon composites. Kalin et al. [8] Claimed that gear performance and durability could be affected by thermal properties with the result showing an increase in operating temperature could decreasing the life cycle of the gear. Hu and Mao [9] investigated misalignment effects on acetal gears together with wear behaviour, with the results demonstrating that acetal gears were most sensitive to pitch misalignment.
