Uniformation GK3 (T) 16K Resin 3D Printer – Excellent Used Condition – Only 193 Hours

If you've done your research, you already know the Uniformation GK3 series is considered one of the premium choices in resin 3D printing, with features that simply aren't found on many printers in this price range.

I've been resin printing for over 10 years and have watched the technology, machines, and industry evolve considerably during that time. After using many different printers over the years, the GK3 has become one of my favorites.

These printers just work.

Whether you're completely new to resin printing or an experienced professional running printers every day, the GK3 is an exceptionally capable machine. In our experience, it has been extremely reliable and consistent compared with many resin printers where failed prints, leveling problems, temperature issues, and constant adjustments can quickly become frustrating.

The combination of the 16K screen, COB light source, smart resin heating system, rigid Z-axis design, built-in camera, and smart connectivity makes the GK3 (T) an excellent choice for anyone looking for exceptional detail and dependable resin printing.

ABOUT THIS PRINTER

For sale is a Uniformation GK3 (T) 16K Resin 3D Printer in excellent used condition with only 193 hours of use.

This printer has been well cared for, professionally used, and is fully functional and ready to print.

We originally purchased five GK3 printers for a special project that is now complete, and we are now selling three of them. All three machines have low hours and have been carefully maintained.

SCREENS & COVER ARE LIKE NEW

One thing we did differently with these printers was leave the original protective plastic film on the exterior screens and printer cover while the machines were being used.

As a result, the surfaces underneath have remained exceptionally clean and protected.

We have intentionally left the protective film in place for the new owner. You get the satisfaction of peeling it off yourself and revealing the clean, like-new surfaces underneath.

GK3 (T) FEATURES

According to Uniformation, the GK3 (T) offers a number of premium features designed for high-detail, reliable resin printing:

16K High-Resolution LCD Printing
The GK3 uses a 15120 × 6230 16K LCD with 14 × 19μm XY resolution, providing extremely fine detail, clean edges, and smooth surfaces—particularly useful for miniatures, scale models, prototypes, and other highly detailed prints.

COB Matrix Light Source
The 405nm COB Matrix light source provides consistent illumination across the printing area for uniform curing and accurate prints.

T-Type Precision Z-Axis
The GK3 (T) uses Uniformation's T-type lead screw Z-axis system, paired with a rigid frame and linear rail system to provide stable and accurate vertical movement throughout the printing process.

Smart Auto Heating System
The integrated heating system automatically maintains the resin at an appropriate working temperature, helping maintain resin flow and consistent curing—especially valuable when printing in cooler environments.

Auto Resin Feeding
The GK3 features an automatic resin feeding system with resin level detection, shortage prevention, continuous resin feeding, and overflow protection.

Built-In Camera
An integrated 720P camera allows you to monitor print progress and can also be used for time-lapse recording.

Wi-Fi & Network Connectivity
The GK3 supports USB, Wi-Fi, and wired network connectivity, providing several options for transferring files and managing your printing workflow.

Large Build Area
The GK3 provides a build volume of approximately 211 × 118 × 240 mm, giving you plenty of room for larger models or multiple smaller parts in a single print.

WHY WE'RE SELLING IT

There's nothing wrong with this printer and we're not selling it because of performance problems.

We purchased five GK3 printers specifically to increase production capacity for a special project. That project has now been completed, so we simply no longer need all five machines.

We're keeping two and selling three.

This particular machine has only 193 hours of use, making it a great opportunity to purchase a lightly used GK3 (T) with several new consumable items already included.

PLEASE SEE THE ACTUAL PHOTOS

The printer shown in the listing photos is the actual printer you will receive.

Please review all photos carefully for cosmetic condition and exactly what is included.

If you've been considering stepping up to a Uniformation GK3 (T) but don't want to pay the price of a brand-new machine, this is an excellent opportunity to pick up a very low-hour, carefully maintained printer that's tested, packed, and ready to go.
