Bambu Lab P2S vs ELEGOO Mars 5 — documented properties and sources
PropertyBambu Lab P2SCOREXYELEGOO Mars 5RESIN
Identity
BrandBambu LabELEGOO
ClassCOREXYRESIN
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab P2S; spec sheet header "P2S Spec Sheet"[1]ELEGOO Mars 5. Elegoo's own product handle spells the configuration out: mars-5-4k-6-6inch-monochrome-lcd-resin-3d-printer[2][3][4]
Street price (USD; dated snapshot per entry)From $549.00 on the Bambu Lab US store, Aug 2026; the product page shows $749.00 with the P2S Combo variant selected[5][6]$179.00 on us.elegoo.com against a $225.00 compare-at price (20% off), in stock, checked Aug 2026. The live product feed shows the same $179.00[3][4]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Two SKUs: P2S and P2S Combo (with the 2nd-generation AMS, which adds filament drying). Do not carry P1S figures across - the P2S differs on nearly every headline number: 600 vs 500 mm/s, 110 vs 100 C bed, hardened-steel vs stainless nozzle, 5-inch 854x480 touchscreen vs 2.7-inch monochrome, 14.9 vs 12.95 kg, 1920x1080 30 fps camera vs 1280x720 at 0.5 fps[1][7]Sold beside the Mars 5 Ultra, which is a materially different machine: 7-inch 9K masking LCD vs 6.6-inch 4K, 18 um vs 35 um pixels, 150 vs 70 mm/h, a 4.0-inch capacitive control screen vs 3.5-inch resistive, and Wi-Fi (the plain Mars 5 is USB only). Elegoo lists ten further Mars 5 / Mars 5 Ultra bundle SKUs pairing the printers with Mercury wash-and-cure stations at $302-$432; those are not printer prices[2][8][3][4]
Market position: superseded? successor announced?Current model, marketed by Bambu as "The Classic Evolves" - the direct replacement for the P1S, which is still sold below it[5]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm (manufacturer figure)[1]143.43 x 89.6 x 150 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)392 x 406 x 478 mm[1]230 x 230 x 433.5 mm[2]
Net weight (kg)14.9 kg net[1]Approximately 6.6 kg[2]
Frame construction & materialPlastic and steel chassis with a plastic and glass outer frame[1]Metal frame with adjustable foot pads[2]
Enclosure: open / enclosed; panel material; door/lidFully enclosed with a door sensor and an activated-carbon (granulated coconut shell) filter with VOC and particulate filtration. No active chamber heater is listed[1]Open-frame MSLA with a removable UV-blocking cover[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY - Bambu positions the P2S as the successor to the P1S platform. The spec sheet itself does not name the kinematics[1][6]MSLA — UV LCD masked stereolithography. Single Z axis, build plate lifting straight out of the vat (no tilt-release on this model, unlike the Mars 5 Ultra)[2][8]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 max toolhead acceleration (manufacturer claim)[1]Not documented
Max volumetric flow claimed (mm³/s)40 mm3/s standard-flow hotend, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive with hardened-steel extruder gears, driven by a Bambu Lab high-precision permanent-magnet synchronous motor rather than a plain stepper; built-in filament cutter[1]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Hardened-steel nozzle, 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported[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 limit110 C max heatbed temperature[1]Not documented
Bed surface (material, texture, coating), single/double-sidedFlexible steel plate; Textured PEI plate included, Smooth PEI Plate and Cool Plate SuperTack supported[1]Laser-engraved build plate with a quick-release design[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedAutomatic levelling, one click. An intelligent mechanical sensor detects resin residue to prevent LCD damage[2]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, tangle sensor, door sensor; filament odometry with AMS[1]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designPart-cooling fan, hotend cooling fan and auxiliary part-cooling fan, all closed-loop controlled[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Motion controller is a dual-core Cortex-M4 plus a single-core Cortex-M7; application processor is a quad-core 1.5 GHz ARM A7 with a 2 TOPS neural processing unit. Board model and chip markings not published[1]Not documented
Input voltage (110/220 V, switch or auto)Not documented100-240 V, 50/60 Hz, 24 V 3 A[2]
Total rated power draw100-120 VAC / 200-240 VAC 50/60 Hz; max 1200 W at 220 V, 1000 W at 110 V; steady state 200 W printing PLA[1]Not documented
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[9]Not named by Elegoo. Supported slicers are Voxeldance Tango and CHITUBOX; STL and OBJ accepted[2]
Connectivity, UI & Camera
Display: size, type, touch?5-inch 854x480 touchscreen[1]3.5-inch resistive touchscreen (control panel — not the masking LCD, see W1)[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus mobile app and PC app; Bambu markets on-device AI error detection[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi (802.11 a/b/g/n, 2.4 and 5 GHz), built-in 8 GB eMMC and a USB port. Ethernet not available; no network kill switch and no 802.1X[1]USB only — no Wi-Fi on this model[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Built-in camera, 1920x1080 at 30 fps - a real video-rate camera, unlike the 0.5 fps unit in the P1 series[1][7]Not documented
Materials Support
Officially supported filament listPLA, PETG, ABS, ASA, TPU, support materials, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF[1]405 nm photopolymer resin. Elegoo does not publish a resin compatibility list on this listing[2]
Safety
Firmware safety limits (max temp cutoffs — exact values)Not documentedIntelligent overheating protection stops printing above 80 °C[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[10]Not documented

Masking LCDNot documented6.6-inch 4K monochrome masking LCD, 4098 x 2560 px, XY pixel pitch 35 x 35 um (manufacturer specification)[2][4]
Light sourceNot documentedCOB LED at 405 nm. Elegoo does not publish an LED count or collimating optics for this model[2]
Vertical print speedmm/hNot documented70 mm/h maximum (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[2]
Release filmNot documentedPFA film with a non-stick surface. No rated life published[2]
Resin vat & feedingNot documentedReplaceable resin tank with two pouring openings and screw caps. An intelligent mechanical sensor detects resin residue in the vat. Capacity not published; no auto-refill[2]
Fume extractionNot documentedNone fitted. Elegoo states compatibility with the separately sold MARS MATE air purifier for odour reduction[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.
