At present, the more mature color printing solutions are as follows:
1. LOM technology
The material used is paper, which is cut layer by layer and superimposed, and ink of the corresponding color is sprayed on each layer, and the corresponding model is finally formed. It is characterized by low cost and high efficiency. The disadvantage is that the model does not have the characteristics of functional materials, which is suitable for teaching models and pure appearance models;
2. Full-color inkjet FDM technology (3DColorJet technology)
Full-color inkjet FDM printing combines FDM and inkjet technology, and uses FDM technology to print the model. After each layer is printed, color inks with CMYK color management are sprayed on the surface of the material. The characteristic is that the surface of the model is brightly colored, the disadvantage is that the printing speed is slow, and the surface of the model has a layered effect;
3. Multi Jet Fusion Technology
This is the full-color 3D printing solution MJF printing technology that HP just released in China. The color ink droplet ejection resolution can reach 1200dpi, and 16 million sRGB colors can be realized. It combines halftone technology and nylon powder to solidify layer by layer, and then cooperate with four colors. The ink jetting scheme can achieve the effect of full-color 3D printing. The advantage is that it does not require 100% utilization of supporting materials and nylon materials. Nylon materials have the characteristics of structural testing and functional verification. The overall scheme has a certain cost-effectiveness. The disadvantage is that the transparent effect cannot be achieved temporarily. And multi-material mixed effect printing;

4. PolyJet Technology
In addition to FDM technology, the other core printing technology PolyJet technology of global printing giant Stratasys, the latest full-color multi-material 3D printer J750 is upgraded and J735 (smaller than J750 in size, 14% lower in price, and other configurations are completely the same as J750. Same) It can support 6 kinds of materials at the same time, adopting jet + light curing scheme, so as to realize the expressive power that other 3D printing technologies do not have, such as the control of model color, hardness, transparency, texture, etc., especially the new content released this time Including newly-added bright color materials (realistic red, yellow, and orange), GrabCAD Print software extended color profile (screen color and the final printed color can achieve consistency), GrabCAD Print software slice function (in the same A print file is printed with full-color VRML texture transparency).As of today, the hardware cost and the cost of consumables are thrown out, and the output result is the highest to judge. Polyjet technology is currently the world's best full-color 3D printing solution, which can achieve voxel-level 3D printing results, full-color + multi-material Provides various possibilities for creativity and customer needs.
5. WJP Technology
This is the main 3D printing technology solution of the domestic company Saina. The technical principle is similar to that of PolyJet. However, the resin material and color management are completely different from Stratasys. It can also achieve full-color and multi-material control. It is currently mainly used in the medical and education industries. It is understood that as the application deepens, more and more functional resin materials will be introduced.
6. CJP Technology
Take 3DSystem’s Projet660 as an example. The CJP technology uses a solution of gypsum powder + jetting CMYK four-color management adhesive. In the past, it was more common in full-color portrait printing services. It is characterized by a relatively low-cost color printing solution. The disadvantage is that the surface fineness and color performance of the model are average.In addition, Japan’s Mimaki’s UV inkjet technology is a 3D printing technology derived from traditional UV lithography. It is similar in principle to Polyjet and WJP, but most of the companies adopting this solution are from traditional two-dimensional printing equipment suppliers. , Canon’s UV flatbed printing machine was able to achieve a 5CM high full-color printing effect very early, and theoretically also belongs to the category of color 3D printing. For traditional brands with UV lithographic printing equipment, the barriers to entry into color 3D printing are relatively low.
