13 of 13 answers for the Bambu Lab X1 Carbon (X1C) are verified against Bambu Lab's published documents, each with its source and date. Checked against Bambu Lab's published documents on 5 October 2026. We have not physically tested this.
Verification means the maker's own page was opened and the quoted words appear on it. It is not a physical test. How we verify.
Bambu lists PLA as suitable for open-frame or enclosed printers and names the X1C as enclosed.
PLA, PETG, TPU, and their CF/GF reinforced materials ... Open-frame or enclosed printer ... Enclosed printer ( Bambu H2 Series, X2D, P2S, X1, X1C, P1S, etc. )
Bambu lists PETG as suitable for open-frame or enclosed printers, recommends an enclosed printer for it, and names the X1C as enclosed.

Note : For PETG and PETG-CF/GF, an enclosed printer is recommended to prevent low ambient temperatures from reducing the model's interlayer strength.
Bambu lists TPU as suitable for open-frame or enclosed printers and names the X1C as enclosed.

Bambu recommends an enclosed printer for ABS and ASA and names the X1C as one.
ABS, ASA, PC, PA, and their CF/GF reinforced materials
Require higher heatbed and chamber temperatures to suppress warping and layer separation

The X1C ships with a hardened steel nozzle. Bambu says carbon and glass-fibre filament needs a hardened steel nozzle.
P1S comes standard with a 0.4mm stainless steel nozzle, X1C comes standard with a 0.4mm hardened steel nozzle
When printing carbon fiber or glass fiber-reinforced materials
Do not use a stainless steel or brass nozzle. Their hardness is insufficient, so they wear out quickly
The nozzle can be replaced as a Hotend with Nozzle or as a Complete Hotend Assembly. The X1 series has its own Complete Hotend Assembly.
If you need to change the nozzle, you can either replace the Hotend with Nozzle or the entire Complete Hotend Assembly.
Complete Hotend Assembly - X1 Series (Note: It is compatible only with X1 and X1C, not with X1E.)
The X1C ships with a 0.4 mm hardened steel nozzle.
P1S comes standard with a 0.4mm stainless steel nozzle, X1C comes standard with a 0.4mm hardened steel nozzle
For carbon and glass-fibre filament Bambu says not to use stainless steel or brass nozzles; the X1C stock nozzle is hardened steel.

Inside the X1 and P1S, above the toolhead, the maker lists one 550 mm tube, 2.0 mm inner and 4.0 mm outer diameter. PTFE tube carries the filament from the AMS or the external spool holder to the extruder, which is inside the toolhead. Bambu recommends replacing the tube every two months under normal use, and inspecting it every month with highly abrasive filaments such as carbon fibre or glow-in-the-dark.

routing it from the Automatic Material System (i.e. AMS) or the external spool holder to the extruder inside the printer toolhead
Under normal usage, we recommend replacing the tube every two months
When printing with highly abrasive filaments (such as carbon fiber or glow-in-the-dark filaments), we recommend inspecting the tube every month
Varies by unit: Bambu says X1 series machines are randomly equipped with different types of build plates.
The X1 series machines are randomly equipped with different types of build plates.
The X1 and P1 series use a spring belt tensioner: loosen the 4 screws, move the toolhead back and forth, retighten, and the spring sets the tension.
Applicable Printer Models X1 Series P1 Series ... The spring system in the belt-tensioner will tighten the belt to the correct tension.
The model name is printed on the front of the printer and shown on its screen.
