Photographs of 3D printed diffusion chambers. A is a photo representation of different parts of a diffusion chamber printed using ABS P430 thermoplastic. The top row indicates the inside view of the chamber, showing the cylindrical interior with interlocking contours. Donor chamber fits in the middle chamber (without a hole) and this setup fits into the receiver chamber. The outside view shows rectangular blocks with smaller cylindrical shafts for stoppers, middle chamber printed chamber with a central orifice, and cylindrical stopper. The isolated cuticular membranes are housed in the middle chamber molecular exchange between and donor and receiver chamber occur through this hole. B is a photo collection of the three thermoplastics used in this research with and without surface coating; ABS M30 (white) uncoated, ABS P430 (ivory) uncoated, and PETG (black) coated with XTC 3D appearing as the shiny centre.
