RT Journal Article SR Electronic A1 Kaspar, Vaclav A1 Rozlivka, Jakub T1 Chemical degradation of 3D printed products JF Manufacturing Technology Journal YR 2020 VO 20 IS 1 SP 45 OP 48 DO 10.21062/mft.2020.010 UL https://journalmt.com/artkey/mft-202001-0010.php AB This template describes the behavior of products created with additive 3D printing technology. The tested material used to produce the samples was polyactide acid (PLA). PLA is one of the most favourite material for 3D printing. This polylactide acid contains a metal additive. The standard dog-bone shaped samples reinforced with internal ribs arranged in a grid with 20% of the internal volume of the rib-filled sample were tested for tensile strength. The samples were subjected to different types of chemical degradation prior to the test. As a degradation agent, there was used an organic solvents. The result of the research is the effect of the degradation factor on the mechan-ical properties of these samples and possible use in practice, specifically in technology.
