Effect of Shock-Variable Environmental Temperature and Humidity Conditions on 3D-Printed Polymers for Tensile Properties

Abstract

The article presents the research results on the influence of variable shock conditions, such as temperature and water, thus reflecting shock atmospheric conditions during freezing and thawing, on the properties of samples produced using 3D printing technology from commonly used materials such as ABS, HIPS, PLA, and ASA. Understanding how different environmental conditions affect the quality, reliability, and durability of 3D prints can help to optimize the printing process and provide valuable information about their application possibilities. Tests related to the strength of the materials, such as static tensile testing, Charpy impact testing, and evaluation of structures, were carried out using a scanning electron microscope (SEM). Changes in chemical properties were measured by performing tests such as FTIR and TGA. Variations in chemical properties were measured by performing tests such as FTIR and TGA. One shock cycle lasting 7 days was sufficient to alter the properties of 3D prints, with the extent of changes depending on the material, as summarized in the test results.

Change in the Low-Cycle Performance on the 3D-Printed Materials ABS, ASA, HIPS, and PLA Exposed to Mineral Oil

“…The specimens were subjected to forces from the zero pulses, and the value of the amplitude stress, σ a , was related in percentage to the tensile strength, as described in Section 2.3 . At each load level, 3 specimens were tested in series [ 31 ]. Tests were conducted at a frequency of 2 Hz, and the number of load cycles to specimen failure was recorded.…”

“…All analyses were performed assuming a significance level below 0.05. A similar method was used in our previous publication [ 31 ].…”

Environmental Durability of Bio-Based and Synthetic Thermoplastic Composites in Large-Format Additive Manufacturing

“…Afshar and Mihut [ 30 ] found that the durability of 3D-printed polymer composite parts could be improved by depositing a thin metallic copper film on the surface of the 3D-printed parts. Glowacki et al [ 31 ] studied the effect of freeze–thaw cycling on the durability of 3D-printed acrylonitrile butadiene styrene and polylactic acid and found that one cycle lasting seven days was enough to alter the mechanical properties of the materials.…”
