biocompatibility of photopolymers in 3d printing
Often referred to as 3D printing (3DP)
Is a concern because, among other things, unique parameters of the manufacturing process affect the physical, chemical and biological properties of AM-
Quality of AM-
Therefore, when building the same parts using different 3D printers, even when using the same 3D printers, parameters, process steps and materials, the equipment produced may vary.
In this new study, representative materials constructed using stereo molding and material injection processes were evaluated using the Organization for Economic Cooperation and Development (OECD)
Fish Embryo trials designed to determine the acute toxicity of chemicals to the fish embryo stage.
Studies have shown that AM materials are toxic in the analysis of zebrafish;
However, after treatment with ethanol, the adverse effects of toxicity of some materials were significantly reduced.
Within the limits of the study, it is clear that material composition and cleaning methods are important parameters for assessing the biological risk of light polymers in 3DP.
In addition, the zebrafish biocompatibility assay is a reliable tool for the evaluation of leaching toxicity in quantitative AM materials.
