位于奥地利的高精度光学设备开发人员视频已经揭示了它声称是用于工业应用的“世界第一个”本地4K UV轻型引擎。
命名为阿凡达（Avatar），轻型引擎基于德州仪器它提供了4096 x 2176的天然分辨率，这是对当前重新位置WGXGA-CHIP像素的当前需求的根本改进，以改善图像分辨率并在DLP投影中实现4K。
该新芯片组将于2022年中期发布，它将使阿凡达用户能够在高分辨率下曝光比以前更大的区域，并以高光学性能进行移动曝光。
“AVATAR is an exciting development,” said Christof Hieger, In-Vision CTO. “The new projection system redefines the boundaries of DLP technology in additive manufacturing and lithography.”
视频’s 4K DLP light engines
现有的4K DLP投影仪通常在光强度和分辨率方面受其芯片组的限制，这一缺点是涉及其自身系统的开发。该公司推出了直升机OS UV light projectorat the end of 2020 with the aim of achieving the highest illumination intensity in the market space, alongside faster cure times and compatibility with a greater number of resins.
The following year, In-vision launched its first4K UV light projector, Phoenix，用于基于树脂的DLP 3D打印机。雷电竞app下载Phoenix是公司第一个基于Texas Instruments的DLP670S芯片组的轻型发动机，并且是专门针对需要高光强度和快速固化时间的应用而设计的。
Now, the firm is looking to take UV light projection to a “new level” for advanced 3D printing applications with the launch of its AVATAR system, which offers native 4K UV light projection.
The AVATAR light projector
Equipped with the native resolution of 4096 x 2176 offered by Texas Instruments’ new chipset, the AVATAR UV light projector will enable 3D printer operators to expose larger areas at high resolution than before, and to make moving exposures with high optical performance. In addition to its native resolution offering, the system also delivers a number of other key features to facilitate a new level of advanced industrial 3D printing.
Issued with a built-in Xilinx Zynq UltraScale feature, the AVATAR is an open system that allows users to customize their applications or use prepared software. The system’s LED module can be easily swapped out without requiring further calibration or setup.
The system is designed to enable moving exposure, coming equipped with an optical PCle interface, optical trigger in/out, and a one-gigabyte ethernet connection to ensure high scrolling speeds. The PCle interface allows the device to handle large amounts of data contained within a 4K image, especially in scrolling mode. Meanwhile, the system’s small width enables projectors to be lined up down to very small pixel sizes.
为了达到高峰性能，轻型投影仪的照明和DMD单元配备了单独的连接器进行水冷却，而OLED显示屏则将其告知用户系统的操作状态和关键参数。
视觉首席执行官Florian Zangerl称：“下一代轻型发动机的首次销售型号将在2022年第四季度使用。”此后，将于2023年的AVATAR系统的连续生产。
Improving DLP 3D printing
The industrial DLP market is continually seeing advancements and, as a result, is becoming increasingly lucrative as big names enter the field. Last year, 3D printer OEMStratasys获得的DLP机器制造商起源andRPS在设定的交易中加强公司的广泛技术产品andstrengthen its position在医疗和工业部门。
Metal 3D printer manufacturerDesktop Metal同时，还进入了DLP市场acquisition of EnvisionTEC for $300 million，为公司提供不断增长的牙科，珠宝和生物打印部门的机会。从那以后，EnvisionTec与Polymer 3D打印专家合作Covestro提供DLP的新材料和打印机组合tooling applications within industrial 3D printing.
另一个用自己的DLP打印进入市场的玩家是AXTRA3D，展示了它的Hybrid PhotoSynthesis (HPS) technologyatFormnext 2021。该平台结合了DLP，SLA和LCD 3D打印的好处，目的是在医疗保健，工业制造业，汽车和航空航天等领域转换Photopomery 3D打印。
