Numerical Simulation on Three-Dimensional Printed Submerged Temephos Larvicide Dispenser for Dengue Prevention

Abstract

Implementation of computer simulation analysis of proposed Temephos submerged dispensers designated as “Floater 1” and “Floater 2” presented in this study contributes to a body of research on the types of interventions used to prevent mosquito-borne diseases. Floaters 1 and 2 are known as cage and cylindrical design, respectively. Modal analysis conducted on both design enabled the authors to further understand and visualize the deformation and stress distribution which correspond to natural frequency of each design. Obtained natural frequency of these dispensers could avoid destructive frequencies caused by external loads acting on both designs. Furthermore, costs related to destructive testing and manufacturing defects would literally be avoided. Hence, a more robust and affordable mosquito control product will potentially be materialized. Combined usage of these submerged dispensers made of polylactic acid (PLA), an environmentally friendly plastic printed via 3D printing with reused or recycled plastic material will gain a widespread use and contribute to the environmental sustainability.
