Abstract： Experimental analyses were conducted on the color mixing effect of the developed full-color FDM 3D printers，verifying the color mixing uniformity of the designed mixing nozzes. Thus，an RGBCMYKW color matching calibration algorithm was proposed based on FDM 3D printing of polylactic acid （PLA）filament and BP neural network. CMYW four-color silk materials were mixed in different proportions to obtain 529 mixed color samples.Using SOFV-1xi image acquisition equipment to extract color （RGB）information from mixed color samples under standard D5O light source，and combining the color information extracted from the standard color card under the same acquisition conditions for color correction， 529 RGB-CMYW color conversion sub samples were obtained. The sub samples were used for training to determine the FDM 3D printing full-color matching calibration algorithm. The developed full-color FDM 3D printer was used to print 24 color chips，and the corresponding color diferences among the printed color chips and the standard 24 color card were analyzedand calculated.Results indicate that thecolor eror difference is generally small and the color features may be wellreplicated. At the same time，actual 3D color model design and printing are carried out，further verifying the reliability and practicality of the proposed color matching algorithm.
