Bambu Lab hotend upgrades by printer series

Bambu Lab hotend upgrades come from Bambu Lab, BIQU, E3D, Micro Swiss, Phaetus and Slice Engineering, sold per printer series. The X1 and P1 series (Bambu Lab P1S, X1 Carbon) take screw-in hotends with the nozzle built into the heat block, while the A1, P2S, X2D and H2 series take clip-in ones. An upgrade changes nozzle material, flow or both; the printer’s firmware still sets the temperature limit.

What hotend upgrades are available for the Bambu Lab P1S?

The Bambu Lab P1S takes Bambu Lab’s hardened steel P1 Series hotend in place of its stock stainless steel nozzle. Third-party hotends from BIQU, E3D, Micro Swiss, Phaetus and Slice Engineering add higher flow, harder nozzles or swappable nozzles. Bambu Lab makes no High Flow or tungsten carbide hotend for it, and no hotend raises its 300 °C limit.

The same designs also fit the Bambu Lab X1 Carbon (some as a separate version), so the table covers the whole X1 and P1 series. The X1 Carbon already ships with a hardened steel nozzle; its upgrade order is on the X1C upgrade path. Fitting Bambu Lab’s hardened steel hotend to a P1S is covered in hardened steel nozzles on Bambu Lab.

Rows are alphabetical by maker. Makers measure flow with different filaments, temperatures and nozzle sizes, so their figures are not directly comparable. E3D notes that a high-flow hotend prints faster only once the slicer’s volumetric flow limit is raised. Bambu Lab’s High Flow hotend compared goes further into flow.

On the X1 and P1 series the nozzle is part of the hotend, so changing nozzle size or material means changing the hotend. Since Bambu Studio V02.01.01.52, the nozzle is set on the printer, not in the slicer. The Panda Revo and Mako bring their own heater, and the Panda Revo its own thermistor. The printer’s thermal protection must match those parts, so follow the maker’s install guide and check that the hotend heats and reads temperature normally before the first print.

What hotend upgrades are available for the Bambu Lab A1?

The Bambu Lab A1 takes Bambu Lab’s clip-in A1/A2 hotends in hardened steel (0.4, 0.6 or 0.8 mm) or stainless steel. Clip-in third-party hotends from BIQU, E3D, Micro Swiss and Phaetus add high-flow, coated, silicon carbide, tungsten carbide or diamond-tipped nozzles. Bambu Lab’s High Flow hotend fits, but Bambu Lab says it adds no flow on the A1.

Each hotend in the table also fits, or comes in a version for, the A1 mini. On these printers the heater and temperature wiring stay in the toolhead when the hotend unclips, so a swap needs no rewiring. Afterward, set the nozzle on the printer under Settings > Maintenance > Nozzle. The A1 stops at 300 °C whatever is fitted.

Rows are alphabetical by maker. BIQU also sells Panda Juicer hotends for the A1 and A1 mini with hardened steel, VantaC or tungsten carbide nozzles. E3D states that its A1 hotends do not void the Bambu Lab warranty because Bambu Lab approved them; for other third-party parts, see does upgrading void the warranty. The A1 mini upgrades guide covers the rest of that printer.

What hotend upgrades are available for the Bambu Lab P2S and X2D?

The Bambu Lab P2S and X2D take Bambu Lab’s High Flow and tungsten carbide hotends, shared with the H2D, H2S and H2C. Clip-in third-party hotends come from BIQU, E3D, Micro Swiss and Phaetus. Bambu Lab rates both printers’ nozzles to 300 °C, and no hotend in the table raises that limit by itself.

The H2 series runs to 350 °C, per the H2D spec sheet. The P2S ships with a hardened steel Standard Flow hotend that Bambu Lab rates at 40 mm³/s (ABS, 280 °C, single-wall model). After any swap, set the nozzle type on the printer: on the P2S, under Filament > Nozzle & Extruder > Nozzle Type.

Rows are alphabetical by maker. BIQU also sells Panda Juicer hotends for the P2S, X2D and H2 series, with hardened steel, VantaC or tungsten carbide nozzles. E3D gives the X2D’s limit as 350 °C, but Bambu Lab’s own X2D page lists a 300 °C nozzle.

Any row listing a temperature above the printer’s rating names the extra parts it needs. Running a Bambu Lab printer above its rated nozzle temperature is at your own risk and may void the warranty. An upgrade that replaces the heater or temperature sensor also changes what thermal protection has to watch, so whatever controls the heater must be set up for the new parts before the first heat-up.

How do you choose a hotend upgrade for a Bambu Lab printer?

Choose by what you print: abrasive filaments call for a harder nozzle and faster printing for a high-flow hotend, while anything above 300 °C depends on the printer’s limit, not the hotend.

• Carbon fiber, glass fiber or glow filament. The P1S and A1 need at least Bambu Lab’s hardened steel hotend; the X1 Carbon and P2S ship with hardened steel. Harder options on this page are tungsten carbide (Bambu Lab, H2/P2S/X2D only; BIQU for the A1, H2, P2S and X2D), silicon carbide (Phaetus), E3D’s ObXidian and ObXiDian 500 coatings, and diamond tips (E3D DiamondBack, the Micro Swiss FlowTech DiamondBack nozzle). The wear-resistant nozzle comparison sets these materials side by side.
• Faster prints. A high-flow hotend, then a higher volumetric flow limit in the slicer. Bambu Lab’s High Flow hotend is for the H2 series, P2S and X2D only; Bambu Lab lists it as not supported on the X1 and P1 series and as no faster on the A1. Owners of those printers choose among the third-party high-flow hotends above.
• Nozzle swaps without changing the hotend. The Micro Swiss FlowTech, Slice Engineering Mako, BIQU Panda Revo and Phaetus Conch High-Flow Wear-Resistant Hotend on the X1 and P1 series, and the Phaetus Conch M4 on the A1, take separate nozzles.
• Above 300 °C. No hotend swap alone gets there on the P1S, X1C, A1, P2S or X2D. Slice Engineering says the limit “is set in the firmware of the printer”, and E3D says its hotends are “restricted by the maximum printing temperature of your machine”: 300 °C on the X1C and P1S, 320 °C on the X1E. Stock, the H2 series reaches 350 °C. Firmware temperature limits explains why.

Is there an E3D Revo hotend for Bambu Lab printers?

Not from E3D. E3D’s catalog lists no Revo hotend for Bambu Lab printers, and its FAQ says the X1 and P1 High Flow ObXidian keeps the stock Bambu Lab nozzle form, so it takes no Revo nozzles. For Revo nozzles on a Bambu Lab X1C, P1P or P1S, E3D points to the BIQU Panda Revo.

The Panda Revo, which BIQU co-developed with E3D, takes every RapidChange Revo nozzle except the Revo Belt nozzle; its figures are in the X1 and P1 table. BIQU lists no Panda Revo for the A1, P2S, X2D or H2 series. BIQU’s store does list E3D’s ObXiDian 500 hotend for the H2, P2S, X2D and A2L as “E3D Revo ObXidian High Flow ObXiDian 500 HotEnd”. It describes the official E3D ObXiDian 500 High Flow hotend, the clip-in part in the P2S and X2D table, not a Revo-nozzle hotend.

How does the Bambu Lab hotend compare with the Phaetus Rapido?

They fit different printers. Phaetus sells no Rapido for any Bambu Lab printer: the Rapido 2 and Rapido 2F are listed as “DIY” hotends, and Phaetus says to match “the mount, wiring, cooling and controller sensor configuration” before fitting one. Its hotends for Bambu Lab printers are the Conch models in the tables above.

The Rapido 2F takes swappable V6-style nozzles and a PT1000 temperature sensor, and Phaetus rates it at up to 36 mm³/s. Bambu Lab rates its H2/P2S/X2D Standard Flow hotend at 40 mm³/s and its High Flow hotend at 65 mm³/s, measured in ABS on a single-wall model. The two makers use different tests, so the figures are not directly comparable.
