| Property | Bambu Lab P1PCOREXY | UltiMaker Factor 4INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | UltiMaker |
| Class | COREXY | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab P1P. Bambu documents it alongside the P1S in a single two-column parameters table[1] | UltiMaker Factor 4[2] |
| Release date (announcement and actual shipping) | Not documented | Announced 22 April 2024, shown at HANNOVER MESSE 2024 (22-26 April) and TCT Asia (7-9 May 2024)[2] |
| Launch MSRP (USD) | Not documented | Starting at approximately $20,000[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | P1P is the open-frame version; the P1S is the same motion platform in an enclosure with plastic and glass panels. Bambu's own comparison table shows what the P1P lacks: control-board fan, chamber temperature regulator fan, auxiliary part-cooling fan and air filter are all listed "Optional" on the P1P and "Closed Loop Control"/"Activated Carbon Filter" on the P1S. The P1P is also lighter, 9.65 kg vs 12.95 kg, and 386 mm deep vs 389 mm. A P1P Enclosure Kit is sold as a spare part. Filament support differs accordingly: ABS/ASA are "Capable" on the P1P but "Ideal" on the P1S[1] | Shares the 330 x 240 x 300 mm envelope with the UltiMaker S5, S7 and S8, which is the single most contaminated figure in UltiMaker's range. What separates the Factor 4 is the actively controlled 70 °C build volume, the climate-controlled 6-spool material station holding humidity below 15%, and HEPA filtration. UltiMaker also sells a Factor 4 Plus[2] |
| Market position: superseded? successor announced? | Superseded. No longer listed in the Bambu Lab US store 3D-printer collection in Aug 2026 (the collection carries A1, A1 mini, A2L, P1S, P2S, X2D, H2S, H2D, H2C); /products/p1p redirects to the collection page and only P1P spare parts remain in the store sitemap. No live first-party price could therefore be recorded[3][1] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm advertised. Bambu's own footnote limits the default printable height in Bambu Studio to 250 mm to avoid heatbed collisions, and warns that the collapsible filament-cutter stopper takes part of the printing area when popped out[1] | 330 x 240 x 300 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 386 x 389 x 458 mm (P1P). Bambu prints P1P and P1S dimensions in the same cell - the P1S is 389 x 389 x 458 mm[1] | Not documented |
| Net weight (kg) | 9.65 kg net, 14.30 kg gross[1] | Not documented |
| Frame construction & material | Open frame; Bambu offers printable mod-plates for the side panels[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Open frame. An official P1P Enclosure Kit exists as a spare part, and the enclosed version of the same platform is sold as the P1S[1][3] | Enclosed with actively controlled chamber airflow and a HEPA filter[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Build volume temperature controlled up to 70 °C with actively controlled chamber airflow (manufacturer specification)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY driven by two stepper motors, each with its own belt to the printhead. Bambu's wiki states the P1P and P1S share the same motion system[4] | Direct-drive dual extrusion; kinematic layout not stated in the source checked[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three leadscrews driven from a single stepper motor through a belt; the whole bed drops in Z. There is no motorised Z-tilt - bed tramming is by three manual knobs under the bed[4] | Not documented |
| Belts (type, width, e.g. Gates?) | Adjustable belt tensioners at the rear; a Belt Tension Monitor reports when tension drifts out of range[4] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive; Bambu sells a "Stainless Steel Extruder Unit (P1 series)" as the service part[4] | Direct-drive dual extrusion[2] |
| Filament diameter | Not documented | 2.85 mm[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | All-metal all-in-one hotend: the nozzle is integrated into the heatblock and joined to the heatsink by a thin metal tube, so the hotend is replaced as a unit. 0.4 mm stainless-steel nozzle included; 0.2/0.6/0.8 mm optional[1][4] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature[1] | 340 °C maximum with the high-temperature print core (manufacturer claim)[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max build-plate temperature[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate; Cool Plate, Engineering Plate and High Temperature Plate compatible[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Nozzle-touch probing against three ceramic force (piezo) sensors under the heatbed: Z homing works by detecting the force of the nozzle contacting the heatbed. Three manual levelling knobs are also fitted[5][4] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - filament run-out sensor[1] | Not documented |
| Spool holder location & max spool size; drybox compatibility | Not documented | Automatic climate-controlled material handling and storage station holding humidity below 15%, storing up to six spools[2] |
| Multi-material/multi-color capability or official upgrade path | Compatible with AMS and the AMS hub, up to 16 colours with four AMS units[4] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan fitted; the control-board fan, chamber temperature regulator fan and auxiliary part-cooling fan that the P1S has under closed-loop control are all listed as Optional on the P1P[1] | Not documented |
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | HEPA filter[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Closed-source proprietary firmware - not a Klipper or Marlin derivative, and no printer-firmware source is published. The bambulab GitHub organisation carries 11 repositories (Bambu Studio, wxWidgets/boost/ffmpeg forks, the wiki); none is printer firmware. Updates are delivered over the air via Bambu Studio / Bambu Handy[6] | Not documented |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 2.7-inch 192x64 monochrome screen, not a touchscreen - control is by button, app or PC application[4] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Button-driven on-device UI on a 192x64 monochrome panel; most interaction is expected to happen in Bambu Studio or Bambu Handy[4] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, Bluetooth and Bambu-Bus; microSD card storage; 5 V/1.5 A USB output power[4] | Not documented |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Low-rate chamber monitoring camera, 1280x720 at 0.5 fps, timelapse supported - the 0.5 fps figure is Bambu's own and is far below video rate[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, TPU, PVA, PET. Capable: PA, PC, ABS, ASA - the open frame is the limiting factor, and the same table upgrades ABS/ASA to Ideal for the enclosed P1S[1] | UltiMaker-branded PPS CF, PLA, Tough PLA, Nylon, PETG, PET CF and PVA, plus validated third-party materials from BASF Forward AM, Kimya, Polymaker, LEHVOSS and Jabil[2] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[7] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Dimensional accuracy within +/-0.2 mm or +/-0.2% of feature nominal length; UltiMaker states it tested over 95% print-completion success. Manufacturer figures, not independent measurements[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.
