Abstract

See full text

A method for additive manufacturing is provided, including: mixing a hardener with a sand material, so that the hardener is evenly coated on a surface of the sand material, and then spraying a binder through a nozzle, reacting the binder sprayed through the nozzle with the surface of the sand material evenly coated with the hardener to harden a sand mold. Therefore, the problem of nozzle clogging may be overcome, and a solid with a particle size of less than 0.6 μm may be obtained by the additive manufacturing. In addition, the hardening speed can be adjusted according to the size of the sand mold. Compared with a general sand mold product, the hardening speed may be increased and the storage life of the binder may be prolonged when the sand mold has a large size.
