UniFormation GK3 Ultra

The GK3 Ultra is designed for creators, studios, and production users who need more build space for large models or higher output per batch. Its 300 × 160 × 300 mm build volume makes it a strong fit for large statues, props, prototypes, and plates containing many smaller parts. If most of your work consists of smaller high-detail parts or transparent applications, compare the GK3 Pro before choosing.

The maximum print volume is 300 × 160 × 300 mm. This gives you room to print larger parts with fewer cuts or arrange more parts on one build plate.Actual usable capacity depends on model orientation, supports, drainage, and the clearance required around each part.

It can support both workflows. Large-format creators can reduce the number of sections required for statues and props, while studios can use the larger plate to produce more parts in one batch.For production planning, compare total successful parts per batch, resin use, cleaning time, and post-processing labor—not only the stated print speed.

The GK3 Ultra can heat the resin to a selected 25°C or 30°C setting to support more consistent resin flow in cooler environments. Its automatic feeding system is designed to maintain resin availability during longer or higher-volume prints.Before the first production print, confirm that the resin cartridge is installed correctly, calibrate the feeding system, and run a short functional test. Never fill the vat beyond its indicated maximum level.

Yes. Resin can be added manually as long as you follow the vat capacity and safety guidance in the user manual. Automatic feeding is a workflow feature; it is not required for the printer to expose and complete a print.If the feeding system does not detect or dispense resin correctly, stop and check the cartridge installation and sensor reading before beginning a long print. Contact technical support if the displayed weight or feeding status remains abnormal.

The printer is factory calibrated, but the build plate should still be checked after delivery, relocation, maintenance, or a failed first-layer test. Complete the official leveling check before committing a full vat of resin to a large print.If adhesion differs across the plate, do not compensate only by increasing exposure. Recheck the plate, vat installation, release film, leveling result, and test-piece thickness first.

First confirm that the printer is using the correct, current firmware and that the resin temperature is stable. UniFormation has published a specific service procedure for heater-related layer patterns on certain earlier GK3 Ultra units.Check the production label on your machine and follow the official GK3 Ultra guide rather than applying an older modification to every unit. Contact support if you are unsure which procedure applies to your serial number.

The GK3 Ultra supports UniFormation Slicer, CHITUBOX, and Lychee Slicer. Print files can be transferred by USB, Wi-Fi file sharing, or Ethernet.Software and network features can depend on firmware version and local network configuration. Keep USB available as a direct transfer option, and verify current compatibility in the Support Center before relying on a remote workflow.

The GK3 Ultra uses a 405 nm light source and supports common resin categories including standard, ABS-like, flexible, water-washable, and compatible specialty resins.Every resin requires a validated exposure profile. Start with the resin manufacturer's recommendation or a tested UniFormation profile, then calibrate for your layer height, temperature, model, and required dimensional accuracy.

The printer measures approximately 455 × 400 × 575 mm. You also need clearance to open and service the machine, handle the build plate safely, store resin, and move prints into washing and curing.Plan the complete workflow before purchase. A large printer without adequate washing, curing, ventilation, spill control, and bench space can create a bottleneck after printing.

Choose post-processing equipment according to the largest part you expect to print, not only the average model. Cure3 Ultra is designed for the larger GK3 Ultra workflow, but washing requirements should also consider part geometry, resin type, solvent volume, and local safety practices.If you already own post-processing equipment, check its internal dimensions before selecting a printer-only configuration.

The GK3 Ultra product page currently lists a one-year machine warranty and a 14-day return and exchange period. Coverage, exclusions, return costs, and eligibility depend on the current policy and your region.Shipping estimates apply only when the selected configuration is available in the relevant warehouse. Review the displayed regional stock status and current policy before placing your order.
