Chinese Patent Application Publication No. CN103665802A discloses a method for modifying PLA materials that can be used for 3D printing. The method utilizes inorganic nanomaterials as toughening agents to toughen and modify PLA. Although this method can improve the toughness of PLA, it does not The heat resistance of PLA did not improve significantly
Chinese Patent Application Publication No. CN104530669A discloses a modified polylactic acid PLA material that can be used for 3D printing and its preparation method. The method utilizes polybutylene succinate as a toughening agent to toughen and modify PLA. Although the method can improve the toughness of PLA, since the modified wire is a two-phase system of PLA and PBS, the tensile strength of the modified PLA is not high, and it is easy to cause phase separation during the printing process, making the printing effect poor.
[0005] In addition, when PLA is used for 3D printing, the temperature of the nozzle is generally around 230°C, and the energy consumption is high, which may easily cause burns to the operator, and is not suitable for 3D printers for children.
Chinese Patent Application Publication No. CN103980682A discloses a 3D printing polycaprolactone material and its preparation method. The method uses carbon nanotubes and graphene as dimension reinforcement materials to prepare modified polycaprolactone 3D with high strength. Printing materials, although polycaprolactone has a melting point of 63°C, it can be used as a wire for children's 3D printers, but its heat resistance is poor, and its application range is limited
