Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K1C (product page title "K1C Carbon 3D Printer")[1]Elegoo Saturn 4 Ultra 16K. Elegoo's product handle is saturn-4-ultra-16k-10inch-monochrome-lcd-resin-3d-printer. 3DJake item number ELG-50.101.038300[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]$649.99 in us.elegoo.com's live Shopify product JSON, in stock, with compare_at_price also $649.99 — no discount active at the time of checking (Aug 2026)[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]Distinct from the earlier Saturn 4 Ultra (12K); the 16K carries a 15120 x 6230 masking LCD with 14 x 19 um pixels. Elegoo also sells it bundled with a Mercury Plus V2.0 wash/cure station and as a pre-owned SKU, neither of which is the printer-only price[2][3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable220 x 220 x 250 mm[1]211.68 x 118.37 x 220 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)355 x 355 x 482 mm[1]327.4 x 329.2 x 548 mm[2]
Net weight (kg)12.4 kg net, 16 kg gross[1]Not documented
Frame construction & materialNot documentedMetal housing with a flip-up cover and a drip guard[2]
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[5]Flip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (Creality's own K1-series comparison table)[5]MSLA with tilt-release: the vat tilts to peel each layer rather than pulling straight up. Elegoo claims the mechanism cuts curing time by 25%. Single Z axis, Z precision 0.02 mm[2]
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 speed300 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 nameDual-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 limit100 C max heatbed temperature[1]Not documented
Bed surface (material, texture, coating), single/double-sidedPEI 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]Automatic levelling, plus intelligent mechanical sensor alarms[2]
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 designDynamically 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 documented100-240 V, 50/60 Hz, 24 V 6 A[2]
Total rated power draw350 W rated power; input 100-120 V / 200-240 V, 50/60 Hz[1]Not documented
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]Elegoo EL3D-4.0 system. Slicer is CHITUBOX[2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch 800x480 colour touchscreen[1]4-inch capacitive touchscreen (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-driveWi-Fi and USB drive; 8 GB on-board storage[1]USB and Wi-Fi, with WLAN file transfer[2]
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]AI camera, 1920 x 1080[2]
Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it?Not documentedAI camera with print-failure detection[2]
Materials Support
Officially supported filament listABS, PLA, PETG, PET, TPU, PA, ASA, PC, PLA-CF, PA-CF, PET-CF[1]405 nm photopolymer resin; the heated tank is aimed at high-viscosity and high-speed resins. No closed compatibility list published[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
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 LCDNot documented10-inch 16K monochrome masking LCD, 15120 x 6230 px, XY pixel pitch 14 x 19 um (manufacturer specification)[2][3]
Light sourceNot documentedCOB light source with a Fresnel collimating lens[2]
Light uniformity & intensityNot documentedLight energy at the plate quoted as 5 mW/cm2, i.e. 5000 uW/cm2 (manufacturer claim, attributed to the tilt-release and Fresnel optics). No uniformity percentage published and no independent measurement[2]
Vertical print speedmm/hNot documentedUp to 150 mm/h (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[2]
Release filmNot documentedPFA release film. No rated life published[2]
LCD life & replaceabilityNot documentedMasking LCD shielded by tempered 9H protective glass. Elegoo publishes no rated screen life in hours and does not state user replaceability[2]
Resin vat & feedingNot documentedReplaceable resin vat with a dual pour spout and a drip guard. Heated tank with automatic temperature measurement: Elegoo states resin reaches 25 C in 26 minutes from a 5 C ambient at 50% humidity (manufacturer figure). Capacity not published; no auto-refill[2]

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.
