Abstract

An apparatus (100) for additive manufacturing of a part includes a print bed (200) including a build sheet (220), a print head/nozzle system (300), and a physical control system (400) providing for relative motion between the print head/nozzle system and the print bed. The build sheet includes a foam material having a glass transition temperature of at least about 140 °C, or 80 wt% to 99 wt% of a cellulose fiber material and from 0.5 wt% to 10 wt% of a binder. The print head/nozzle system includes at least one print head and nozzle and is configured to apply an additive manufacturing material (330) onto the print bed. In some aspects the build sheet includes a reinforcing substrate. In further aspects a method for additive manufacturing a printed part includes applying a plurality of layers (340) of an additive manufacturing material onto a print bed to form the printed part.
