Zusammenfassung:	In order to overcome the disadvantages and the defects that the compatibility of cellulose and a polymer matrix is poor, hole blockage can be easily caused during printing, materials are single in color and the like, firstly, colored microcrystalline cellulose is obtained by carrying out acid pickling on common cellulose by adopting an inorganic acid solution, then carrying out modification treatment by utilizing a silane coupling agent and a color-developing reagent in an alcohol solution, and regulating pH (Potential of Hydrogen) value of a mixed solution through acid-base regulation; the problem of compatibility between the microcrystalline cellulose and a PLA matrix is solved; then, a colored microcrystalline cellulose reinforced PLC (Polylactic Acid) 3D (Three-Dimensional) printing material with good mechanical performance and good 3D printing performance as well as different colors is obtained by taking the colored microcrystalline cellulose as a reinforced material and PLC as amatrix and carrying out m
