| Property | Creality K1CCOREXY | Formlabs Form 4RESIN |
|---|---|---|
| Identity | ||
| Brand | Creality | Formlabs |
| Class | COREXY | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K1C (product page title "K1C Carbon 3D Printer")[1] | Formlabs Form 4 3D Printer[2][3] |
| Street price (USD; dated snapshot per entry) | $369.00 on store.creality.com, Aug 2026. Creality's comparison page shows $529 against a struck-through $559 on the same day[4][5] | Starting at $2,625.00 at GoEngineer, in stock, checked Aug 2026. Formlabs sells the printer as part of packages (Form 4 Complete Package etc.), so package prices are much higher than the printer-only figure[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The carbon-fibre-capable K1. Against the K1: all-metal hotend and a steel-tipped tri-metal "unicorn" nozzle integrated with the heatbreak instead of metal+PTFE and copper; air filter fitted instead of absent; 1080p AI camera, foreign-object detection, remote monitoring, time-lapse, build-surface detection and failure detection all standard instead of optional; a much longer filament list including PLA-CF, PA-CF and PET-CF. Build volume, footprint, speed and screen are identical to the K1, so a spec box that lists only those numbers cannot tell the two apart. A K1C Bayern Edition also exists[1][5] | Three machines share this platform and are constantly conflated. Form 4: 200 x 125 x 210 mm, 50 um pixels, 18.3 kg, 480 W, one resin cartridge, NOT biocompatible. Form 4B: identical hardware but validated for 38 Formlabs materials including 15 biocompatible. Form 4L: 353 x 196 x 350 mm, 46 um pixels, 58.5 kg, 900 W, two cartridges[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 220 x 220 x 250 mm[1] | 200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 355 x 355 x 482 mm[1] | 398 x 367 x 554 mm[2][3] |
| Net weight (kg) | 12.4 kg net, 16 kg gross[1] | 18.3 kg[2][3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with passive chamber heating only - Creality's comparison table lists "Passive Heating" for the K1, K1C and K1 Max and no chamber heating for the K1 SE[5] | Enclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (Creality's own K1-series comparison table)[5] | Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; 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[5][1] | Not documented |
| Recommended/typical print speed | 300 mm/s typical printing speed with 12000 mm/s2 typical acceleration, stated by Creality alongside the 600 mm/s headline[5] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[5] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct-drive extruder[5] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | All-metal hotend with a tri-metal "unicorn" quick-swap nozzle - a steel-tipped copper nozzle integrated with the heatbreak, replaced as a unit[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 limit | 100 C max heatbed temperature[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | PEI flexible build plate[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Hands-free auto levelling[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor fitted; power-loss recovery[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Dynamically balanced closed-loop part-cooling fan; dynamically balanced PWM hotend fan; activated-carbon air purifier fitted[1] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 4.8 A, 50/60 Hz, 480 W[2] |
| Total rated power draw | 350 W rated power; input 100-120 V / 200-240 V, 50/60 Hz[1] | 480 W[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Creality OS, a Klipper derivative - the K1-series firmware source is published as CrealityOfficial/K1_Series_Klipper on GitHub under GPL-3.0, described by Creality as a clone of upstream Klipper. Creality also lists the printhead front cover and side-mounted spool holder as open-source parts[6][7][5] | Proprietary. Print preparation is PreForm; fleet management is Formlabs Dashboard[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch 800x480 colour touchscreen[1] | 7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI with sleep mode, lighting control and input shaping; remote monitoring, time-lapse and AI failure detection are included rather than optional[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi and USB drive; 8 GB on-board storage[1] | Dual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[2][3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | AI camera fitted as standard, 1080p, with foreign-object detection and failure detection[5] | Not documented |
| Materials Support | ||
| Officially supported filament list | ABS, PLA, PETG, PET, TPU, PA, ASA, PC, PLA-CF, PA-CF, PET-CF[1] | Formlabs resins across rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic and castable families. Biocompatible resins require the Form 4B, not the Form 4[2] |
| 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[6][7] | 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[8] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[2][3] |
| Review scores from major outlets (list outlet + score + date) | Tom's Hardware rating 4.5 out of 5 in the page's structured data[9] | Not documented |
| Resin & MSLA | ||
| Masking LCD | Not documented | Low Force Display masking LCD with a 50 um pixel size and pre-tuned anti-aliasing. Formlabs does not publish the screen diagonal or pixel count[2][3] |
| Light source | Not documented | Backlight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[2][3] |
| Vertical print speedmm/h | Not documented | Maximum 100 mm/h; average 40 mm/h at a 100 um layer height (manufacturer figures — GoEngineer publishes both, which is unusually explicit about the basis). Formlabs separately claims most prints finish in under 2 hours[3][2] |
| Layer height range | Not documented | 25-200 um per Formlabs' own tech-spec page; GoEngineer's listing for the same machine says 25-300 um. Unresolved[2][3] |
| Resin vat & feeding | Not documented | Single next-generation resin cartridge; Formlabs claims 5-10x faster filling and 63% less waste. Resin tank rated for 75,000+ layers with any Formlabs material. No vat capacity published[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.
