摘要：
A method of making dental articles Abstract The present disclosure provides a method of making an article having a desired color, the method comprising the steps of: (a) providing a color array, said array comprising a plurality of 5 distinct color points, each color point being independently composed of a resin mixture comprising one or more masterbatch resins; (b) comparing the desired color with the color points on the color array and selecting a color point that substantially corresponds to the desired color of the article; (c) identifying the resin mixture corresponding to said selected color point; and (d) making the article using said identified resin mixture. (No suitable figure)

1. A method of making an article having a desired color, the method comprising the steps of: (a) providing a color array, said array comprising a plurality of distinct color points, 5 each color point being independently composed of a resin mixture comprising one or more masterbatch resins; (b) comparing the desired color with the color points on the color array and selecting a color point that substantially corresponds to the desired color of the article; (c) identifying the resin mixture corresponding to said selected color point; and 10 (d) making the article using said identified resin mixture. 2. The method of claim 1, wherein the color array comprises at least 36 color points, each color point having a color value, determined in accordance with the CIE (International Commission of l’Eclairage) system. 3. The method of claim 1 or claim 2, wherein the color array comprises at least 144 color points, each color point having a color value, determined in accordance with the CIE system. 4. The method of any one of the preceding claims, wherein each resin mixture comprises 20 at least two masterbatch resins. 5. The method of claim 4, wherein each resin mixture comprises about three to five masterbatch resins. 25 6. The method of any one of the preceding claims, wherein the comparing step comprises selecting a color point having a color difference value (?E) of less than 6. 7. The method of any one of the preceding claims, wherein the making step comprises using said identified resin mixture in a 3D printing process. 8. The method of claim 7, wherein the 3D printing process is selected from the group consisting of: stereolithography (SLA), Digital Light Processing (DLP) and Continuous Liquid Interface Production (CLIP). 35 9. The method of any one of the preceding claims, wherein said article is a dental article. 10. The method of any one of the preceding claims, wherein the desired color is determined based on the color of a human tooth.
