Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab P1S. Store title: "Bambu Lab P1S 3D Printer"[1]Prusa CORE One+ (Gen 2) INDX, listed as "INDX 4-Tool" and "INDX 8-Tool" variants and as an "INDX 8-Tool Assembly kit"[2][3]
Release date (announcement and actual shipping)Not documentedAnnounced as shipping on 20 August 2026 ("INDX, Shipping Has Started, Complete Printers Open for Orders"). Prusa's own front page in Aug 2026 announces "Prusa CORE One+ (Gen 2) INDX, Shipping Has Started, Complete Printers Open for Orders", with the assembled 8-tool machine quoted as shipping from 15 October and the kit from 29 October[4][2]
Street price (USD; dated snapshot per entry)From $369.00 (base P1S) on the Bambu Lab US store, Aug 2026, against a stated typical price of $399.00; with the P1S AMS 2 Pro Combo variant selected the same page shows $539.00 against a typical $579.00[5][1]$1,850.93 for the INDX 4-Tool and $2,082.41 for the INDX 8-Tool on prusa3d.com, Aug 2026; the 8-Tool assembly kit is $1,804.63. Camera and filtration bundles run to $2,152.78[2][3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Enclosed version of the P1P and mechanically the same motion platform. Three SKUs on one product page: P1S, P1S AMS Combo and P1S AMS 2 Pro Combo (the AMS 2 Pro adds active filament drying). Sibling figures that get mixed up: net weight 12.95 kg (P1S) vs 9.65 kg (P1P); depth 389 mm vs 386 mm; ABS/ASA Ideal (P1S) vs Capable (P1P). Also distinct from the 2026 P2S, which is a different machine (600 mm/s, 110 C bed, 5-inch touchscreen, 14.9 kg)[1][6]INDX is a multi-tool option on the CORE One+ (Gen 2) product page rather than a separate printer, sold in 4-tool and 8-tool configurations, plus a CORE One/+ INDX conversion kit for existing machines. All of the body, hotend, bed and electronics figures below come from that shared CORE One+ (Gen 2) page and were not published separately for the INDX machine, so treat them as platform figures. Prusa also sells the unrelated MMU3, which multiplexes five filaments through one nozzle[3][2]
Market position: superseded? successor announced?Still sold in Aug 2026, but Bambu now markets the P2S as "The Classic Evolves" above it in the same enclosed-CoreXY slot[5][7]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm advertised. Bambu's own footnote sets the default printable height in Bambu Studio to 250 mm to prevent heatbed collisions, and notes the collapsible filament-cutter stopper occupies part of the print area when popped out[1]250 x 220 x 270 mm - the CORE One+ (Gen 2) figure from the shared product page; Prusa does not publish a separate INDX build volume[3]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 458 mm; package 485 x 480 x 530 mm[1]415 x 444 x 555 mm - shared CORE One+ (Gen 2) figure[3]
Net weight (kg)12.95 kg net, 17.60 kg gross; the AMS Combo ships at 21.60 kg gross and the AMS 2 Pro Combo at 21 kg gross[1]Not documented
Frame construction & materialSteel chassis (shared with the P1P) inside plastic and glass panels[1]Not documented
Enclosure: open / enclosed; panel material; door/lidFully enclosed - plastic and glass panels with a glass front door and lid, plus an activated-carbon air filter. No active chamber heater; the chamber temperature regulator fan is closed-loop controlled[1]Fully enclosed with active chamber heating up to 55 C (shared CORE One+ platform)[3]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY driven by two stepper motors, each with an independent belt to the printhead; the P1P and P1S share the same motion system[8]CoreXY with a multi-tool head-changing system (INDX); Prusa's comparison table gives CoreXY for the CORE One family[3]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree leadscrews belt-driven from a single stepper motor, whole bed moving in Z; manual tramming by three knobs under the bed, no motorised Z-tilt[8]Not documented
Belts (type, width, e.g. Gates?)Rear adjustable belt tensioners with a Belt Tension Monitor[8]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 nameDirect drive; the service part is the "Stainless Steel Extruder Unit (P1 series)"[8]Nextruder direct drive, 10:1 planetary gearbox (shared platform)[3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)All-metal all-in-one hotend with the nozzle integrated into the heatblock, replaced as a unit; 0.4 mm stainless-steel nozzle included, 0.2/0.6/0.8 mm optional[1][8]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]290 C claimed max nozzle temperature, 400 C with the optional HT hotend (shared platform)[3]

Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Nozzle-touch probing using three ceramic force (piezo) sensors mounted under the heatbed - Z homing is done by detecting the force of the nozzle contacting the bed[9][8]Load-cell sensor, fully automatic first-layer calibration (shared platform)[3]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - filament run-out sensor[1]Filament sensors fitted (two on the CORE One+ platform)[3]
Multi-material/multi-color capability or official upgrade pathAMS-compatible; sold as P1S AMS Combo and P1S AMS 2 Pro Combo, up to 16 colours with four AMS units[1]INDX gives up to eight filaments; the alternative MMU3 handles five through a single nozzle[3]

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[10]Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[11][12]

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[13]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][12]

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.
