▎ 摘  要

NOVELTY - Method for manufacturing a carbon molded body by three-dimensional printing, involves (a) providing a first layer containing a first raw material resin, (b) irradiating the first layer with laser light to carbonize it in a first non-oxidizing atmosphere, (c) providing a second layer containing a second raw material resin on the first layer after carbonization, and (d) in a second non-oxidizing atmosphere, carbonizing the second layer by irradiating it with a laser beam, where the carbonized first layer and the carbonized second layer are integrated. USE - The method is used for manufacturing a carbon molded body by three-dimensional printing. ADVANTAGE - The method easily manufactures various carbon molded bodies regardless of size, preferably large-sized carbon molded bodies can be easily manufactured, since a firing furnace is not used.
