Everyone needs a 3d printer. They just don't know it. You are probably hearing a lot about 3d printing during the COVID-19 pandemic. Colleges, schools, businesses and even boys scouts are using 3d printers to make n95 masks, face shields and parts for ventilators. If you had a 3d printer at home, you could be making your own Personal Protective Equipment for your family and friends right now and perhaps for front line medical workers.
