Abstract: A method of additive manufacturing is comprised of providing a material comprised of a ethyl cellulose polymer having an ethoxy content of 43% to 52% by mass and a plasticizer. The material is heated and dispensed through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base and successive layers of the material are adhered on the initial layer to form an additive manufactured part by repeating the aforementioned steps. The article formed of the ethyl cellulose polymer may be used in many applications such as those related to the pharmaceutical and food industries.
