Problems solved by technology

UV curable materials are available in a wide range of physical properties (e.g., tensile strength, tensile modulus, flexural strength, etc.) but a limited number of colors, and due to different cure rates and final cure hardness values ​​may preclude having multiple colors The printing of products, so using different colors is a particular challenge

example 1

[0121] This example describes the formation of an exemplary solid structuring ink and the characterization of some of its physical properties.

[0122] A dye-based ink formulation was prepared as follows: To a 30 mL amber glass bottle was added 2.019 g CD406, 1.007 g SR368, 2.843 g CD587 (all from Sartomer Company Inc.), 0.825 g Unilin 350 Acrylate (Acrylate Curable Monofunctional Acrylic Ester wax C22, C23, C24 mixture, melting point between 50 and 60 ° C), 2.528 g Licowax KFO (an ester wax, available from Clariant), 0.155 g Irgacure 819, 0.224 g Irgacure 184 and 0.100 g Irgacure 907 ( Both are available from Ciba Specialty Chemicals). A stir bar was added to this mixture and the mixture was placed in a Variomag reaction block. The ink mixture was heated and stirred separately at 90°C and 300 RPM for at least 20 minutes or until the mixture appeared homogeneous. The temperature was increased to 100°C, held for five minutes, and then 0.300 g of BlueOlefin dye was added. The...

Abstract

The present invention provides a color three-dimensional (3D) printing system comprising (1) solid building inks for each of a plurality of colors, each solid building ink comprising (a) in an amount of about 40% by weight to about 70% by weight solid acrylate, (b) non-curable wax in an amount from about 10% to about 45% by weight, (c) curable wax in an amount from about 1% to about 15% by weight, (d) photoinitiator, and (e) colorant; each solid builder ink has a cure rate adjusted by the ratio of non-curable wax to curable wax, so that the initial cure rate and final hardness of each solid builder ink is for a variety of Each of the colors is approximately the same, and (2) a support material comprising the non-curable wax used in each builder ink that provides a scaffold for the deposition of each builder ink.

Description

technical field [0001] The present invention relates to three-dimensional printing. In particular, the invention relates to three-dimensional printing using UV-curable solid inks capable of carrying different colorants. Background technique [0002] Three-dimensional (3D) printers are becoming increasingly popular for home and professional applications. There are many advantages to using a 3D printer, including faster, more cost-effective, and high-throughput prototype evaluation. Currently, 3D printers offer several solutions for selective deposition modeling for professional use. [0003] Typical printing systems apply UV curable hot melt materials via inkjet to a non-curable wax carrier. Each layer, typically micron in size, is cured after deposition. When fabrication is complete, the support material is washed away, melted or blown away, depending on its composition, leaving behind the 3D artifact. UV curable materials are available in a wide range of physical prope...
