Longer Orange 4k 3d resin printer unboxing I purchased this 3D resin printer in February and after some delays due to holidays, manufacturing QA checks and customs delays it arrived today. Sorry for some of the audio and my rambling a bit. Was excited to finally get it and hope to try if out soon with more information on print quality and specs. I still need to check the model ordered and see if I have the right resin so I will follow up on that in a future video and comments for this video. The majority of LCD 3D printers in market are built in 5.5” 2K resolution of LCD screen, and the conventional pixel size of screen is 47.25um, is there any way to get a higher precision solution? If upgrade the 2K LCD screen to higher resolution for 4K, the pixel size will be driven down to 31.5um. Furthermore, if a pixel can be divided into 3 subpixels, the resolution in one direction will be as fine as 10.5um, which is a dramatic improvement over the 2K LCD screen. With the algorithm embedded in Longerware, the UV exposure through each subpixel will be controlled accurately to deliver final 3D models with ultra-smooth surfaces and ultra-fine details. Orange 4K is improved with one stand cover, built by metal body and dual liner guide, which is more stable and reliable. And it’s integrated with 2.8” touch screen, plastic resin vat with scale and simple levelling declined built plate. The printed volume of Orange 4K is 118*66*190mm(4.64”*2.6”*7.48”). Orange 4K is equipped with 5.5” LCD screen, and there’re color & mono screen in configuration, reaching at 4K resolution 812 PPI. When configurated with color screen, one pixel in XY direction is 31.5um; while update with mono screen, one pixel of X direction is 31.5um, but Y direction has driven down to 10.5um. Moreover, The LCD screen has been improved on manufacturing procedure, and coated with glass cover over the screen, which will be better on protection. Orange 4K will be compatible with LongerWare, Chitubox & Lychee slicer, and we will setup the default printing parameter for color screen and monochrome screen. It will be much easier for user to select and configurate the printing parameter. Orange 4K Color 3d printer is able to upgrade to mono screen as well, but need to update the firmware. When Orange 4K is configurated with mono screen, the printing speed is up to 2s per layer, which will be increasing by 300% to reach at 60mm/h. ... https://www.youtube.com/watch?v=83UpbEAB8j0
