| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K1 (store title "Creality K1 Speedy 3D Printer")[1][2] | Original Prusa XL+, Single-Tool variant ("Prusa XL+ Single-Tool" in the e-shop variant data)[3][4] |
| Release date (announcement and actual shipping) | Not documented | The XL+ refresh was announced on 13 August 2026, on sale immediately in all toolhead configurations, with assembled printers shipping later in August 2026 and upgrade kits for existing XL owners from around the end of August. The original Original Prusa XL predates it[5] |
| Street price (USD; dated snapshot per entry) | $299.00 on store.creality.com, Aug 2026. Creality's own K1-series comparison page shows $389 against a struck-through $599 on the same day[2][1] | $2,128.70 on prusa3d.com, Aug 2026 (lowest listed price for the Single-Tool variant; the Enclosure bundle starts at $2,610.19)[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Base model of the K1 family. The differences that matter are in the hotend: the K1 uses a metal + PTFE-tube hotend with a copper nozzle, while the K1C is all-metal with a steel-tipped nozzle integrated with the heatbreak and adds an air filter and a 1080p AI camera. Creality's own comparison table annotates the K1 hotend "Changing to All-metal Soon", so the hotend on a given unit depends on when it was built - check before buying. The K1 Max is the 300 mm version with 1000 W rated power and Ethernet; the K1 SE has a PA+30%GF hotend and an epoxy plate[1][6] | The XL+ is sold in Single-Tool, Dual-Head and Five-Head variants at $2,128.70, $2,768.52 and $3,610.18 respectively (Aug 2026), plus Enclosure bundles and a Critical Infrastructure edition. The frame is the same in all of them - Prusa states the frame is ready for toolheads to be added at any time - so build volume, bed and electronics figures are shared and only the toolhead count and price differ. The XL+ is itself a revision of the Original Prusa XL: the older XL aligned toolheads with a mechanical pin, the XL+ uses a dedicated electronic sensor, adds a nozzle wiper and is claimed to print 10-15% faster[3][4] |
| Market position: superseded? successor announced? | Not documented | Current model; an Original Prusa XL to Prusa XL+ upgrade kit is sold for existing owners[4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 220 x 220 x 250 mm[1] | 360 x 360 x 360 mm, which Prusa states as 46.7 litres[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 355 x 355 x 480 mm[1] | About 700 x 900 x 720 mm (Prusa's own figure is approximate)[3] |
| Net weight (kg) | 12.5 kg (Tom's Hardware measurement)[7] | About 30 kg[3] |
| Frame construction & material | Not documented | Aluminium extrusions and steel sheets (Prusa's comparison table for the XL)[8] |
| 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[1] | Open frame. The Enclosure for Prusa XL+ is an optional add-on; Prusa says the printer is ready for chamber temperatures up to 60 C, that the new better-sealed enclosure reaches around 50 C on the printer's own waste heat, and that 60 C needs an upcoming chamber heater for which no shipping date has been given[3][5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (Creality's own K1-series comparison table)[1] | CoreXY with 1.5 mm GT belts, Input Shaper and Phase Stepping[3] |
| Belts (type, width, e.g. Gates?) | Not documented | 1.5 mm GT belts[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][6] | 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[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[1] | Not documented |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input Shaper and Phase Stepping[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct-drive extruder[1] | Nextruder direct drive; each toolhead carries its own extruder, hotend, nozzle and filament[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Metal hotend with a PTFE (Teflon) tube in the filament path and a copper nozzle. Creality's own comparison table adds "(Changing to All-metal Soon)", so this is a moving target across production runs[1] | Quick-swap nozzles - 0.25 mm for detail, 0.6/0.8 mm for speed, hardened steel for abrasives, high-flow CHT for throughput; toolheads ship with high-flow nozzles[3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 290 C claimed max nozzle temperature[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature[1] | 120 C max heatbed temperature[3] |
| Bed surface (material, texture, coating), single/double-sided | Coated steel flex plate, heated, removable[7] | Segmented heatbed of 16 individually controlled tiles across the 360 x 360 mm surface, so only the tiles under the part are powered; removable double-sided satin print sheet supplied[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic bed levelling (Tom's Hardware); unlike the K1 Max there is no lidar[7][9] | Load-cell sensor - the nozzle is the probe, which Prusa says automatically accounts for nozzle changes, surface textures and thermal expansion and removes manual Z-offsets. Toolhead-to-toolhead alignment on the XL+ uses a separate permanently mounted eddy-current Tool Offset Sensor, replacing the removable mechanical pin used on the original XL[3][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor fitted[7] | Filament sensors fitted; Prusa's comparison table lists two filament sensors for the XL[8] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Closed-loop part-cooling fan; PWM hotend cooling fan[1] | 360-degree part cooling on each toolhead, new on the XL+ and matching the MK4S and CORE One arrangement; Prusa states it delivers more airflow and distributes it more evenly around the nozzle. Additional fans and heatsinks cool the electronics. Fan sizes are not published[3][5] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Custom 32-bit xBuddy electronics with STM32 (Prusa's comparison table for the XL)[8] |
| Total rated power draw | 350 W rated power[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Creality OS, a Klipper derivative. Creality publishes the source as CrealityOfficial/K1_Series_Klipper on GitHub, whose own description is "clone from https://github.com/Klipper3d/klipper/", GPL-3.0, last pushed December 2025[10][11][1] | Open-source firmware - Prusa states "Firmware: Open-source; ships with the full current Prusa feature set", and the XL is covered by the prusa3d/Prusa-Firmware-Buddy source tree[3][12] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch 800x480 colour touchscreen[1] | 3.5-inch 65k-colour screen with touch control (Prusa's comparison table for the XL)[8] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; remote monitoring, time-lapse, failure detection and build-surface detection are all optional on the K1 because they depend on the optional AI camera[1] | On-device touch UI; Prusa Connect and the Prusa mobile app are optional - Prusa states the machine is fully offline capable[8][3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi only - no Ethernet (the K1 Max adds RJ45); 8 GB of on-board storage[1] | Ethernet, optional Wi-Fi; USB drive for print files. Prusa Connect optional and fully offline operation supported[3][8] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | AI camera optional, not fitted as standard - unlike the K1C and K1 Max, which include a 1080p camera[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Hyper PLA, PLA, PETG, TPU, ABS - a notably shorter list than the K1C, because of the PTFE-lined hotend[1] | PLA, PETG, ASA, ABS, PC, PA (nylon), TPU, PVA, HIPS, PP, CPE, PVB and carbon-fibre composites. Prusa states an open material policy - any brand of 1.75 mm filament, no chips and no subscriptions[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[10][11] | Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[13][12] |
| 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[2] | 2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[14][8] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Tom's Hardware rating 4 out of 5 in the page's structured data - the lowest of the K1 family, where the K1C and K1 Max both score 4.5[7][9][15] | Not documented |
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.
