Bambu Lab P1S vs UltiMaker S8 — documented properties and sources

BrandBambu LabUltiMaker
ClassCOREXYINDUSTRIAL
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab P1S. Store title: "Bambu Lab P1S 3D Printer"[1]UltiMaker S8 3D Printer[2][3]
Release date (announcement and actual shipping)Not documentedLaunched March 2025; the technical-specification and pricing announcement is dated 14 March 2025[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]Starting at $8,999 at MatterHackers, in stock, checked Aug 2026. The launch announcement quoted approximately $9,000[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][5]Sold as printer-only or as a Pro Bundle. The bundle is not a trim level but a different machine footprint and weight: 495 x 500 x 1210.5 mm and 47.7 kg with the 6-spool Material Station, versus 495 x 585 x 800.5 mm and 30 kg for the printer alone. Print cores AA+ 0.40 x2 are included; BB, CC+ and DD 0.40 are separate purchases[2][3]
Market position: superseded?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][6]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]330 x 240 x 300 mm[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 458 mm; package 485 x 480 x 530 mm[1]495 x 585 x 800.5 mm printer only; 495 x 500 x 1210.5 mm as the Pro Bundle[2][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]30 kg printer only; 47.7 kg as the Pro Bundle[2][3]
Frame construction & materialSteel chassis (shared with the P1P) inside plastic and glass panels[1]Fully assembled, made in Europe[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]Enclosed, with an Air Manager UltiMaker says removes up to 95% of ultrafine particles[2][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[7]Dual-extrusion print head with auto nozzle-lifting, flood detection and inductive probing. UltiMaker's Cheetah motion planner uses third-order continuous motion with corner blending[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[7]Not documented

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[8][7]Inductive probing, integrated into the print head[2][3]

Dimensional accuracy measurements (third-party, with numbers)Not documentedDimensional accuracy +/-0.15 mm +/-0.15% of feature nominal length (manufacturer specification, not an independent measurement)[2][3]

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.
