PLA is a workhorse 3D printing material. It is easy to print, strong, rigid, and economical.
You can use PLA for a variety of different applications, from detailed models to working prototypes.
Please note that these properties are heavily dependant on part geometry and printing parameters. When submitting an order, be sure to indicate how the part will be used so we can help meet your needs!
This stress strain curve was created with the help of the materials testing lab here at McMaster University in JHE. Tensile tests were performed on samples 3D printed with 2 perimeters, 3 top & bottom layers, and 20% infill. As these results are unique to these parameters, only use the stress strain chart to compare materials. We cannot guarantee that your part will have the same properties.
