In the field of 3D printing, fused filament fabrication (FFF), many PLA filaments are offered by different providers. The physical properties of the filaments from various manufacturers differ significantly from each other. These differences have corresponding effects on the processing of the filaments, as well as on the quality of the final product. This article compares PLA filaments from different manufacturers and additionally gives an overview of their physical properties. The investigated properties were namely the melting point, cold crystallization, glass transition temperature, melt flow index and residual content. The results show the differences between the various manufacturers' specifications in the data sheets and point out others. The melt flow index in particular stands out here, which can have a strong influence on the printing process. The effect especially on the mechanical properties has to be determined in further investigations.
