Design and Adsorption Performance Study of 3D Printing Water Treat-ment Reactor Based on Polylactic Acid
[Purposes]The influence of layer thickness,printing speed,printing temperature,and infill density on the tensile strength of polylactic acid(PLA)specimens was investigated.The water absorption and methylene blue adsorption of the 3D printing water treatment reactor based on PLA were studied.[Methods]Utilizing UG three-dimensional modeling software,a three-dimensional model for printing mechanical test specimens was designed.The orthogonal test was used to print and analyze the data.The PLA hollow cube material(water treatment reactor)was printed with optimal printing parameters to test water absorption and methylene blue removal.[Findings]The results indicated that optimal tensile strength was achieved when the printing layer thickness was 0.3 mm,printing speed was 70 mm/s,printing temperature was 210 ℃,and infill density was 40％.The study revealed that the water absorp-tion rate of this PLA water treatment reactor is 12.79％,with a methylene blue removal rate of 76.10％.[Conclusions]This suggests that the hollow PLA water treatment reactor obtained through 3D printing possesses significant adsorption capability for methylene blue,indicating substantial potential for appli-cation in the field of contaminated water treatment.
