Rapid Prototyping Material Degradation: a Study of Mechanical Properties

This work presents a study on rapid prototyping material degradation through the time. The material degradation used was Veroblue840 resin from Objet and was analyzed by its mechanical properties. Two types of tests were realized: tensile strength test (standard tests ASTM) and an experimental cantilever beam. The specimens were tested with 0, 30, 60, 90 and 120 days aging. Mechanical properties such as tensile strength, Young's modulus, strain at Yield Point and deformation (microstrains) were analyzed. Results show the aging degradation process was not linear through the time, being more accentuated at the first 30 days.
