Meet the brand new Orange 4K
The Longer3D Orange 4K is the evolution of the brand’s affordable resin 3D printer portfolio, which includes popular models such as the Orange 10 or Orange 30. Like its predecessors, the Orange 4K uses LCD-based stereolithography technology, also called MSLA (masked stereolithography).
Basically, an array of LED sources shines consistent light onto the resin tank. This light is filtered in or out in specific shapes thanks to an LCD screen that acts as a sort of stencil over the light.
The Orange 4K is one of the best affordable resin printers available today, boasting ultra-high precision and resolution, and a dual linear guide for increased stability. When it comes to speed, it’s also one of the fastest, printing at a speed of up to 2 seconds per layer.
Other interesting features include a color touchscreen and a temperature detection warning system to avoid overheating.

UHD (Ultra-High Definition) prints
LCD resin 3D printing technology allows users to produce highly detailed prints all while being much faster than laser-based resin methods. Additionally, the better the screen’s resolution, the better the print’s details and resolution will be.
The Orange 4K features a 4K LCD screen with 812 PPI to provide the best details possible at this point in time with LCD technology. It’s subpixel array offers up to 3 times more pixels than a 2K screen does.
This enables shapes to have a much smoother appearance and offers much more granularity for fine details. In fact, the Orange 4K’s mono screen boasts the highest precision (X 31.5um, Y 10.5um on the Mono version) available on the market now, in terms of LCD resin printers at this price range.
Everyone has their software preferences, and it’s unpleasant when you’re forced to use one specific software.
Longer3D has made their printers open-source, meaning the Orange 4K is compatible not only with their proprietary Longerware suite, but also with the popular Chitubox and Lychee options.
