LONGER Orange 4K Resin 3D Printer【Pre-Order】

Product Description
  • Ultra High Precision】Orange 4K is a ultra high precision resin 3d printer, built-in 4K Mono LCD screen at 6480 x 3840 resolution of X 31.5µm Y 10.5µm in subpixel. With such high precision printing technology, it will be perform more details and better surface on miniatures. 
  • Dual Z Axis Liner Guides】Orange 4K is built with dual liner guides for more steady printing and no wobble issues, it will be providing with better result and smoother surface on models.
  • Uniform Parallel UV Lighting】Orange 4K is built with parallel UV LED lighting sources, and provide better uniformity, higher intensity and shorter time of curing.
  • Easy Operation & Algorithm Embedded】 Easy leveling with four screws. 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 compatible with Chitubox as well. 
  • Fast Cooling & High Temperature Warning System】Temperature detection system included. The system will stop printing when temperature is too high. Equipped with high efficiency cooling system to improve lifespan of this 3D printer.
  • Warranty and Service】NOTE: The printer comes without resin. 12-Month machine warranty and Lifetime Technical Support. High-efficiency and considerate community support by us.
  • O4KC Upgrade O4KM】Orange 4K Color upgrade to Orange 4K Mono stesp, please reach this article for reference here
  • Inventory】We will ship the printer from China and Euro customers don't need pay the import tax and VAT.

What's the difference for Orange 4K?

Why Subpixel is BETTER?

If we 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.

  • Compared with Normal 4K Mono Screen
  • O4K is X3 in pixel number
  • O4K is higher precision
  • Normal 4K is 5.5-6.6 inch mono screen without subpixel in comparasion
  • Compared with Normal 2K Mono Screen
  • O4K is X6 in pixel number
  • O4K is X6.7 higher in precision  
  • Normal 2K is 5.5-6.1 inch mono screen without subpixel in comparasion

Subpixel means smaller size of each pixel and more pixel numbers on screen.

What's the BENEFIT of subpixel?

With the algorithm embedded in Longerware and firmware, the UV exposure through each subpixel will be controlled accurately to deliver final 3D models with ultra-smooth surfaces and ultra-fine details.

  • Compared with Normal 2K Mono Screen
  • O4K is much Finer of model
  • O4K is much Smoother of surface
  • Normal 2K is 5.5-6.1 inch mono screen without subpixel in comparasion
  • Compared with Normal 4K Mono Screen
  • O4K is finer of model
  • O4K is Smoother on surface
  • Normal 4K is 5.5-6.6 inch mono screen without subpixel in comparasion

Subpixel will delivery BETTER QUALITY of printing!

Ultrafine Precision at 10.5/31.5µm

Orange 4K 3d printer is reaching at 6480*3840 in resolution with 10.5/31.5µm of subpixel, which will provide much finer and better quality on printing

5.5" Mono Screen with Protector

This resin 3d printer build with mono screen and come with screen protector to provide longer lifespan on printing and better protection for screen

Fast Printing with Mono Screen

This LCD 3D Printer is able to print by 1.5s/layer on exposure time and provide super fast printing than color screen, dramatically increased by 2.5-3 times

Parallel UV Lighting Sources

Orange 4K is configurated with parallel UV LED for uniform and intensity of illumination, and provide better performanace on printing quality

Dual Z Axis Design

LONGER Orange 4K 3d printer is equipped with dual Z axis linear guides for more steady printing, it could be performed much better and stable for tiny details

Full Metal Body

Orange 4K is built with full metal body to keep whole printing procedure more in steady and less wobble, providing reliable quality of printing
