There are growing demands in assistive devices for the aging population, especially those with dementia, visual impairment, stroke, Parkinson's disease, and rheumatoid arthritis. We decided to use the 3D printing fused deposition modeling (FDM) to produce the Goodeat serving plate assistive device after determining the problems by observations and interviews and assessment of several materials and production methods. Through the application of 3D printing technology on the production assistive device, we look forward to bring more convenience to the public.
