Abstract: A method of preparing fiber includes blending bio-compatible ceramic powder and first polyester to form a ceramic powder composition, wherein the bio-compatible ceramic powder and the first polyester have a weight ratio of 10:90 to 60:40. The method further includes blending the ceramic powder composition and second polyester to form a composite material, wherein the ceramic powder composition and the second polyester have a weight ratio of 0.4:99.6 to 40:60. The method also spins the composite material to form a fiber. The first polyester has an intrinsic viscosity (IV) of 0.35 dL/g to 0.55 dL/g, and the second polyester has an intrinsic viscosity (IV) of 0.6 dL/g to 0.8 g/dL. The fiber can be woven to form an artificial ligament/tendon.

Abstract: Provided is a printing system with intelligent color-matching, including a storage device, a printing device, and a processing device. The storage device stores a program, a color-matching dataset, and a color-matching model. The color-matching dataset contains multiple pieces of color-matching data, and each piece of color-matching data includes an ink formula and a corresponding printing color value for the ink formula. The printing device is controlled to produce printed products. The processing device loads the program from the storage device to perform the following tasks: training the color-matching model using the color-matching dataset; inputting the expected color value into the trained color-matching model, and obtaining a predicted formula output by the trained color-matching model; and based on the predicted formula, controlling the printing device to produce the printed product.
