Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K1 Max[1]Formlabs Form 4 3D Printer[2][3]
Street price (USD; dated snapshot per entry)$549.00 on store.creality.com, Aug 2026. Creality's comparison page shows $799 against a struck-through $899 on the same day[4][1]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 large K1. Build volume 300 x 300 x 300 mm and footprint 435 x 462 x 526 mm, both much larger than the K1/K1C's 220 mm cube and 355 mm-wide body; rated power is 1000 W against 350 W; it is the only K1 with RJ45 Ethernet. Its hotend is the older metal + PTFE-tube type with a copper nozzle, annotated by Creality as "Changing to All-metal Soon" and "Copper Nozzle Changing to Steel-tipped Nozzle Integrated with Heatbreak Soon", so hotend type varies by production run - do not assume it matches the K1C[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 usable300 x 300 x 300 mm[1]200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)435 x 462 x 526 mm[1]398 x 367 x 554 mm[2][3]
Net weight (kg)18 kg (Tom's Hardware measurement)[6]18.3 kg[2][3]
Enclosure: open / enclosed; panel material; door/lidEnclosed 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[1]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)[1]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[1][5]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?)Metal hotend with a PTFE tube and a copper nozzle, both annotated by Creality as changing to all-metal and to a steel-tipped integrated nozzle "soon"[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-sidedSmooth PEI steel flex plate, heated[6]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic bed levelling assisted by a lidar sensor - Tom's Hardware records "Automatic + LIDAR", a feature the K1 and K1C do not have[6][7][8]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted[6]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designClosed-loop part-cooling fan and PWM hotend fan, both annotated as changing to dynamically balanced versions; activated-carbon air filter fitted[1]Not documented
Electronics & Power
Input voltage (110/220 V, switch or auto)Not documented100-240 VAC, 4.8 A, 50/60 Hz, 480 W[2]
Total rated power draw1000 W rated power - nearly three times the K1/K1C figure[1]480 W[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Creality OS, a Klipper derivative published as CrealityOfficial/K1_Series_Klipper on GitHub (GPL-3.0); the printhead front cover is listed as an open-source part[9][10][1]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 remote monitoring, time-lapse, build-surface detection and failure detection all included[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi plus RJ45 Ethernet - the only K1-series machine with a wired network port; 8 GB 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)1080p AI camera fitted as standard with foreign-object detection[1]Not documented
Materials Support
Officially supported filament listABS, 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[9][10]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[11]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedXY 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[6]Not documented
Resin & MSLA
Masking LCDNot documentedLow 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 sourceNot documentedBacklight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[2][3]
Vertical print speedmm/hNot documentedMaximum 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 rangeNot documented25-200 um per Formlabs' own tech-spec page; GoEngineer's listing for the same machine says 25-300 um. Unresolved[2][3]
Resin vat & feedingNot documentedSingle 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.
