Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K1 SE[1]UniFormation GKtwo 10.3" 8K Resin Printer[2][3]
Street price (USD; dated snapshot per entry)Creality's K1-series comparison page lists $359 for the K1 SE (Aug 2026); it does not appear as its own product on the Creality US store printer sitemap, so no separate live store price could be recorded[1]$749.99 on uniformation3d.com but marked Sold out, checked Aug 2026 (the page shows a compare-at price of $0.00, i.e. none set)[2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)The cheapest K1. It keeps the 220 mm cube volume, CoreXY frame and 600 mm/s claim but drops a lot: hotend body is PA+30%GF rather than all-metal, the build plate is epoxy rather than PEI, there is no air filter, no chamber heating entry at all in Creality's table, no foreign-object or failure detection, and the AI camera, remote monitoring and time-lapse are optional. Its filament list stops at Hyper PLA, PLA, PETG and TPU. It does get the steel-tipped nozzle integrated with the heatbreak and dynamically balanced fans, which the base K1 does not[1]UniFormation lists GKtwo variants by region and bundle (GKtwo ALL, GKtwo ALL UK) rather than by hardware, so the hardware specification is common; what changes is what ships in the box. Not to be confused with the earlier GKone[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable220 x 220 x 250 mm[1]228 x 128 x 245 mm[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)355 x 355 x 482 mm[1]350 x 315 x 455 mm[2][3]
Net weight (kg)Not documented20 kg packaged (UniFormation publishes package weight, not net weight)[2][3]
Enclosure: open / enclosed; panel material; door/lidEnclosed body, but Creality's comparison table leaves chamber heating blank for the K1 SE where the K1, K1C and K1 Max are listed as passive heating[1]Open-frame MSLA with a UV-blocking cover[2][3]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (Creality's own K1-series comparison table)[1]MSLA — photocuring LCD, single Z axis, straight-lift peel[2][3]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max printing speed (manufacturer claim). Creality's own footnote says the 600 mm/s figure was achieved in Creality Lab and that the typical speed is 300 mm/s[1][4]Not documented
Recommended/typical print speed300 mm/s typical printing speed with 12000 mm/s2 typical acceleration, stated by Creality alongside the 600 mm/s headline[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 max acceleration (manufacturer claim)[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDual-gear direct-drive extruder[1]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Hotend body in PA+30% glass fibre with a steel-tipped nozzle integrated with the heatbreak - not the all-metal assembly of the K1C[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heatbed temperature[1]Not documented
Bed surface (material, texture, coating), single/double-sidedEpoxy flexible build plate - different from the PEI plate on the K1C[1]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designDynamically balanced closed-loop part-cooling fan and dynamically balanced PWM hotend fan; no air filter[1]Not documented
Electronics & Power
Input voltage (110/220 V, switch or auto)Not documented110/220 V[2][3]
Total rated power draw350 W rated power[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Open-source Creality OS, a Klipper derivative (CrealityOfficial/K1_Series_Klipper on GitHub, GPL-3.0)[5][6][1]Not named. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[2][3]
Connectivity, UI & Camera
Display: size, type, touch?Not documented5-inch touchscreen (control panel — not the masking LCD, see W1)[2][3]
On-device UI capabilities (model preview, per-object controls, etc.)Colour touch UI; remote monitoring and time-lapse are optional because they require the optional AI camera[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi[1]USB file transfer[2][3]
Materials Support
Officially supported filament listHyper PLA, PLA, PETG, TPU only[1]402.5-405 nm photopolymer resin. No closed compatibility list published[2][3]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not verified directly. Creality's published firmware for the K1 series (CrealityOfficial/K1_Series_Klipper, GPL-3.0) is described by Creality itself as a clone of upstream Klipper, and upstream Klipper ships the verify_heater thermal-runaway check; whether Creality's stock printer.cfg enables it, and with what thresholds, was not checked here[5][6]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Creality's US store states "Up to 12-Month Warranty", a 14-day return and refund window and "Lifetime Customer Support" on its printer product pages. The "up to" wording means the term is not uniform across parts[7]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedPrinting tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[2]
Resin & MSLA
Masking LCDNot documented10.3-inch masking LCD, 7680 x 4320 px (8K), XY pixel pitch 29.6 um (manufacturer specification)[2][3]
Light sourceNot documentedPhotocuring LCD light engine at 402.5-405 nm. UniFormation does not publish the LED count or optical design on this page[2][3]
Layer exposure timesNot documented2-3 s per layer at 0.05 mm layer height (manufacturer figure — one of the few makers here that states the layer height its exposure figure assumes). Sortable value is the midpoint[2][3]
Layer height rangeNot documented0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[2][3]
Resin vat & feedingNot documentedResin vat capacity 0.7 kg, with built-in resin heating: UniFormation quotes warming to 95 F (35 C) in 8 minutes from 50 F. No auto-refill and no level sensing published[2][3]
Fume extractionNot documentedBuilt-in odour filter[2][3]

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
