UniFormation GK3 ULTRA 16k SLA Resin Printer with HUGE 13.5" screen and 160x300x300mm build volume

Uniformation GK3 Ultra — 16K Large Format Resin 3D Printer

The Uniformation GK3 Ultra redefines what's possible with desktop resin printing. With a 300×160×300mm build volume, a true 16K resolution screen, and a fully automated resin feeding system, the GK3 Ultra is built for creators, professionals, and small studios who need large, highly detailed prints without constant babysitting.

True 16K Resolution — 20×26μm Pixel Size

The GK3 Ultra's 13.5" monochrome LCD delivers a native 15120×6230 pixel resolution, achieving an XY pixel size of just 20×26μm. That level of detail is typically reserved for industrial equipment. The COB light source and Fresnel lens system distribute UV light uniformly across the entire build platform — no soft edges, no dimming in the corners, every print sharp from edge to edge.

Automated Resin Feeding — Print Without Interruptions

The GK3 Ultra's intelligent auto-feed system monitors the resin vat continuously and refills it from the 1.2kg resin box automatically, eliminating the most common cause of large-format print failures. A built-in heating system maintains optimal resin temperature at 25°C or 30°C regardless of ambient conditions, keeping viscosity consistent from the first layer to the last.

Dual-Rail, Dual Ball Screw Z-Axis

Industrial-grade Z-axis stability comes from a dual-rail, dual ball screw design that virtually eliminates Z-wobble — even at the fastest print speeds. Each layer lands exactly where it should, delivering consistent accuracy across the full 300mm print height. At 2–3 seconds per layer at 0.05mm, throughput is exceptional for a printer at this resolution.

Fast Workflow — Quick-Release Build Plate & Resin Vat

Post-processing starts the moment the print ends. The quick-release build plate and resin vat system let you swap plates and start the next build in seconds. A built-in resin drip hanger keeps your workspace clean during plate removal. The 5-inch capacitive touchscreen handles all controls, and files can be sent via USB, Wi-Fi, or Ethernet.

Who Is the GK3 Ultra For?

The GK3 Ultra is the right choice for tabletop miniature creators who need armor-sharp detail at scale, jewelry designers and dental professionals requiring micron-level accuracy, product designers prototyping large functional parts, and print farms needing reliable, unattended overnight runs. If you're producing anything where detail and volume both matter, this machine removes the compromises.
