Desktop 3D printer manufacturerPrusa已经宣布推出其最新基于树脂的LCD 3D打印机，SL1S Speed.
Intended as a successor to the company’s debut MSLA system,SL1，新的和改进的SL1S速度配备了大量重大升级。除了25％的打印区域，该系统的打印速度比其年轻的兄弟姐妹快三倍，疗法时间低至每层1.4秒。SL1针对生产者，设计专业人士和中小型企业，适合从高度详细的桌面模型到功能原型的所有事物。
Prusa Research的创始人兼首席执行官JosefPrůša写道：“虽然速度是这里的主要词，但这并不是牺牲质量的代价。相反，SL1S速度比原始SL1提供了更好的打印质量。我们几乎更换了引擎盖下的所有东西，因此，尽管SL1的外部看起来相同，但这是一个非常不同的3D打印机。”
桌面3D打印与prusa
By this point, Prusa is a household name in the 3D printing community, with an extensive portfolio of desktop machines catering to both hobbyists and professionals. The original SL1 was the company’s first dance with resin 3D printing, featuring a build volume of 120 x 68 x 150mm and a potent 5.5″ 2K LCD screen. As was the plan, the system managed to break past the hobbyist barrier and has seen use in the临床与实验医学研究所(IKEM) in Prague, as well as several other dental and manufacturing facilities.
但是，Prusa的名称更像是FDM 3D打印。该公司屡获殊荣的i3系统目前正在MK3S+型号, and offers a build volume of 250 x 210 x 210mm. Available as both an assembly kit and a ready-to-use system, the 3D printer combines performance and affordability, and has sold several hundred thousand units worldwide.
The SL1S 3D printer
Prusa对投资组合的最新成员的构建量为127 x 80 x 150mm，以及新的和改进的5.96英寸单色LCD屏幕（2560 x 1620），以启动。已知单色LCD比其RBG对应物更快，更耐用，这是由于紫外线传输的改善。SL1的打印速度为80mm/hr，LCD寿命为2000小时。此外，该系统的倾斜和平台运动速度也增加了两倍。
为了补充新的LCD屏幕，PRUSA还完全重新设计了SL1的UV LED系统。新的3D打印机不是与RGB设置合作良好的旧V形反射器，而是配备了LED阵列的四倍，其功能是旧型号的四倍。根据该公司的说法，现在通常需要20-30秒的工业树脂可以在四秒钟内打印出来。
As far as extra features go, the build platform has been revamped to contain a quick-release mechanism, meaning there shouldn’t be any need to recalibrate the SL1S every time a print is removed. The resin vat is designed to work with non-proprietary third-party films, and there’s even a resin level detector to prevent overflows. Finally, the system also features a carbon filter to minimize odors and Wi-Fi functionality, enabling users to manage their print jobs from a web browser.
