Kickstarter Ending

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.
