A patent for an SLA 3D printer capable of producing multicolor objects has emerged. Filed by Taiwanese 3D printer manufacturerxyzprinting该文件在2018年6月详细介绍了公司提议的“自动彩色技术”。该发明专为增值税聚合而设计，这将是一个行业，尽管粘合剂喷射和FDM/FFF已经遥遥无期。
Comparing SLA to color binder jet and FFF systems in the patent, XYZPrinting states that the method’s capability of only 3D printing “monochromatic 3D physical models” leaves room for “more effective solutions.”
从6年内的0 - 15台机器起
A division ofKinpo Electronics Inc.,xyzprintingwas founded in 2013, first as a provider of desktop 3D printers. In 2017, the company rapidlyexpanded its 3D printer range为了涵盖SLS，工业市场的粘合剂喷气机和DLP功能。目前，在台式机和工业中，该公司的3D打印机系列跨越了15种不同的机器。
在桌面系列中，XYZ生产诺贝尔系列SLA系统和Da Vinci 3D打印机gained a color editionin 2017. The XYZPrintingda Vinci Color 3D printeroperates using FFF technology. Inside the print bed however, a inkjet head has been added which sprays plastic layers with droplets of color.
Layer-by-layer, pixel-by-pixel color
在XYZ提出的SLA系统中，将通过在光模块旁安装的着色模块添加颜色。在这种情况下，可以假定系统中的树脂将是清晰的，无色的，并且类似于Da Vinci颜色，通过液体喷雾添加不同的音调。但是，尚不清楚XYZ是否会固定精确的颜色像素，从而可以像颜色FFF对象一样实现逼真的细节。也可能是系统获得不同的预定色调。
对象的所需颜色是按层层确定的，考虑到该层中的每个颜色像素。如文档中所述，“颜色打印数据的每一层都是2D颜色图像[…]，根据对象打印数据的每个像素的像素值；根据颜色打印数据的每个像素的像素值，该步骤配置为在切片物理模型的相应位置上进行颜色。”

Peng-yang Chen is listed as the technology’s sole inventor, and has been credited with a series of other IP filing for XYZ including “Three-dimensional printer and a three-dimesnional printing module thereof” 2018年12月起飞。
No information currently exists to suggest that XYZPrinting is planning to take this SLA project to fruition. In fact, if every patent came true we may already haveflying carsby now. However, the company’s proven appetite for innovation, and its track record for producing machines should not be underestimated.
