Why consider it?

A 16K display with 14 × 19 µm pixels and heating settings of 25 or 30 °C, according to the manufacturer. Automatic refill supports longer jobs.

What to verify

The 385 nm light source requires compatible resin. Its 211 × 118 × 240 mm volume is smaller than the GK3 Ultra.

The specifications that matter

Materials
Resins with confirmed 385 nm compatibility and suitable exposure profiles; check each formulation.

Allow room for supports and the chosen orientation. Confirm the exact nozzle, feeder, included accessories and installation clearance against the manual and seller’s listing.

Which projects fit?

The GK3 Pro is suited to miniatures, busts and small parts with fine surface details. Its 211 × 118 mm plate can hold groups of small models, while the 240 mm height accommodates taller designs. Leave room for supports and for the orientation chosen in the slicer when checking whether a project fits.

UniFormation specifies a 15120 × 6230 display resolution and 14 × 19 µm pixels. Those figures describe the display rather than guaranteed dimensional accuracy for a finished part. Exposure, resin behavior and support placement still affect the result.

Resin and temperature

The light source operates at 385 nm. Before reusing a bottle from another machine, check that its maker supports this wavelength and supplies suitable settings. A label mentioning only 405 nm does not establish compatibility with this printer. Test a small part before committing a full plate.

Built-in heating offers settings of 25 and 30 °C. This can help maintain more consistent conditions in a cool workspace, while the correct target still depends on the resin instructions. A ball-screw Z axis guides the build plate during printing.

Plan the complete workspace

Automatic resin refill reduces the need for manual top-ups during longer jobs. You still need to check the available supply and inspect the vat before starting a batch. Printing is only one stage: washing and final curing require their own equipment and a suitable space for handling uncured parts.

USB, WiFi and Ethernet provide several ways to transfer files. Camera monitoring and app features depend on the available software and firmware. Confirm which remote functions are active before making them a requirement for your workflow.

What to compare

The GK3 Ultra offers a larger build volume for bigger pieces or more models on each plate. The Pro is the more compact option. Compare replacement vat films, screens and compatible resin availability as well as the printer itself: these determine how conveniently you can keep using the machine over time.

Frequently asked questions

Is this the same printer as the GK3 Ultra?

No. The GK3 Pro has a 211 × 118 × 240 mm build volume; the GK3 Ultra is a separate, larger model.

Will every 405 nm resin work?

Compatibility is not guaranteed. The GK3 Pro uses a 385 nm light source, so confirm suitable resin and exposure settings.

Does heating replace post-curing?

No. Heating conditions the resin during printing. Finished parts still need washing and curing according to the resin instructions.
