Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab P1S. Store title: "Bambu Lab P1S 3D Printer"[1]QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[2][3]
Release date (announcement and actual shipping)Not documentedNot published by QIDI on the pages checked (Aug 2026)[2][3]
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[4][1]$399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[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][5]Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[2][6][7]
Market position: superseded?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[4][8]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]175 x 180 x 170 mm advertised[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 458 mm; package 485 x 480 x 530 mm[1]370 x 362 x 397 mm[2]
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]10.5 kg[2]
Frame construction & materialSteel chassis (shared with the P1P) inside plastic and glass panels[1]QIDI publishes no frame-material breakdown for this model[2]
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]No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[2]
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[9]CoreXY[2][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[9]Not documented
Belts (type, width, e.g. Gates?)Rear adjustable belt tensioners with a Belt Tension Monitor[9]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1]<=500 mm/s (manufacturer claim)[2][3]
Max acceleration (claimed, mm/s²)20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1]20,000 mm/s2 (manufacturer claim)[3]
Max volumetric flow claimed (mm³/s)Not documented30 mm3/s extruder flow (manufacturer claim)[2][3]
Extruder
Type (direct drive / bowden) & design nameDirect drive; the service part is the "Stainless Steel Extruder Unit (P1 series)"[9]Direct-drive extruder, single, 1.75 mm filament[2][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][9]Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2][3]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]<=300 °C claimed[2][3]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedBrass[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max build-plate temperature[1]<=120 °C claimed[2][3]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate; Cool Plate, Engineering Plate and High Temperature Plate compatible[1]Double-sided flexible magnetic RF plate[2]
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[10][9]16-point automatic bed levelling per QIDI's US page; probe technology not named[3]

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[12]1-year coverage (QIDI standard store terms)[13]

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.
