Abstract: Additive manufacturing (AM), in particularly Fused Disposition Modeling (FDM) process are relevant to the three topics discussed in this project. In contrast with the previous studies on face mask, the design of face mask is a great improvement but there are still flaws existence. The identified concerns are user comfortability due to wearing it for long hours and face mask production time. These problems arise due to the ongoing pandemic and the time taken to produce a face mask is a crucial factor. The process taken to produce a face mask can consider to be reduced. Lithophane is a term whereby an image that can be seen with penetration of light source through a thin, translucent sheet. The contrast of the image also contributes to the thickness of the parts making these areas clearer or darker. The lithophane process requires conversion of 2D image into 3D surface structure which introduced surface texture. Bistable structure is a type of reconfigurable structure that instantly switches from a stable state to another stable state which consist of functional shape that behaves similarly to mechanical actuation. Size effect is one of the concerns in this phase of experience, whether to determine when will buckle occurs.
