Influence of Material Colour on Mechanical Properties of PLA Material in FDM Technology
Today, one of the most used material in FDM (fused deposition modelling) 3D printing technology is PLA (polylactic acid). On market today, there are many different companies that producing PLA material filament for 3D printers with different diameter and colours. Previous research showing that there are so many parameters in FDM technology that affect on mechanical properties of 3D printed material like layer height, infill density, temperature etc. Topic of this article is to investigate whether colour of PLA material effect on material tensile properties and in what amount. It will be tested more than 10 different colours of PLA material, and for every colour it will be tested 3 specimens. Specimens are prepared according to ISO 527-2, and all printed with same 3D printing parameters and with 100% infill. Also, all used materials are of same company and for every colour specimen will be 3D printed from same filament spool. All this is done to avoid other parameters to effect on material properties. The results of this study will be useful for colour selection of the PLA material without compromising the material tensile properties of 3D printed product.
