Mechanical properties of 3D print materials
One of the most important factors for the final printed result is material selection. Our engineers have been carefully monitoring market for available materials and selecting them for our portfolio.
Very important factor are the mechanical properties of the materials. The properties of the base material change during the printing process; therefore, we provide our own material tests of printed samples for each material.
Available materials with material properties are listed below. All parameters are from tests on printed material samples, not simply from testing of the base filament.
Test conditions and the found material properties are summarized below together with detailed test reports for individual materials:
