Plug Production for Thermoforming using Fused Deposition Modelling

Abstract

Plug, a type of male mould in thermoforming, is mostly produced by conventional processes such as machining. However, in this study, plugs that are used in thermoforming were produced using Fused Deposition Modelling (FDM). Plugs were produced using Polylactic Acid (PLA) and Aluminium (Al) particle reinforced PLA filaments by a 3d printer. Plugs that are produced by FDM, were polished using 800, 1000, 1200, 1600 and 2000 grit sandpapers to reduce friction. Also, thermal effects such as temperature distribution on the region where the plug touches the plastic sheet, were investigated. It has been found that FDM can be a significant alternative for male mould production in thermoforming. Additionally, PLA filaments have great potential for tool production in thermoforming.
