Tensile Strength of PLA Parts Produced by FDM 3D Printer
Many different types of materials are used for 3D printing. Each material have some advantages and disadvantages, so there is really important proper selection of building material for model or final part production. Published paper present actual results of research. Presented are results of tensile strength measurement on prepared specimens built from ecological PLA plastic material. PLA plastic material is in this time the most used material for 3D printing with Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF) technology, because its really good and positive properties and easy processing. This material is also ecological, because is produced from renewable sources, not from crude oil, which pollute our environment. The whole testing and measurement was managed and controlled by a prepared experimental plan. There are selected possible important factors, which are act in the experiment in two or three levels. Presented full factor experiment if based on this input data. The results of measurement were evaluated by selected statistical method as ANOVA is.
