Application failure mode effect analysis on 3D printing COVID-19 face mask

Abstract

The condition of the Covid 19 virus outbreak in the world, especially in Indonesia in early 2021, is still experiencing an increase, although in terms of the percentage it has decreased compared to before. Health protocols according to WHO recommendations by using masks, washing hands with soap in water flow and social distancing are still implemented even though some people have given vaccine injections. Making masks made by 3 D printers in the Production Systems laboratory at Widyatama University to be distributed to the public still has defects in making these masks. FMEA can be used as a way to reduce product defects in mask production to prevent the Covid-19 virus by using a 3D printer. Each stage of the process must be evaluated and brainstormed to calculate the RPN value of each failure that will result in a defective product. The highest failures were printing stopping in the middle and reducing layer shift and developing a set of work procedures for printing personnel. After applying from FMEA, the number of defective products has decreased since the 8th day of production of Covid-19 masks with this 3D printer. © 2021 Karadeniz Technical University.
