Bambu Lab P1S vs X1C: Is the Extra $200 Actually Worth It?
The P1S and X1C are almost the same printer — but almost is doing a lot of work. Here is exactly what you get for the extra $200 and who actually needs it.
Bambu Lab P1S vs X1C: Is the Extra $200 Actually Worth It?
This is the question I get asked most often by people who have already decided on a Bambu printer. They know they want the enclosed, full-featured version. They just do not know whether to spend $699 on the P1S or $899 on the X1C.
I owned the X1C first. I bought it in early 2024 when it was the top of the Bambu lineup and I wanted the best available. About eight months later, the P1S launched and I bought that too. For several months I ran them side by side — the same models, the same filament, the same slicing settings — to actually understand where they diverge.
My conclusion: the P1S and X1C are 85% the same printer. The 15% difference is real, technically meaningful, and actually matters to specific use cases. The question is whether your use case is one of them.

What the LiDAR Sensor Actually Does
The X1C has a LiDAR (Light Detection and Ranging) sensor mounted on the printhead. If you have never used a device with LiDAR, it fires a laser and measures the reflection to build a 3D map of whatever it is scanning. On the X1C, it does four specific things.
1. First layer scan. Before starting a print, the X1C uses LiDAR to scan the bed surface and create a micro-level flatness map. This goes beyond the ABL probe that both printers use — it catches subtle high and low spots that the probe misses, and adjusts the first layer height in real time as the nozzle moves across the bed. In practice, this means the X1C’s first layer is more consistent across the full bed, especially on large flat prints like phone cases or thin tiles.
2. Flow rate calibration. The LiDAR scans the width of the extruded filament line in real time and compares it to the target width. If the flow is too high or too low, the X1C adjusts extrusion multiplier on the fly. This is called “AI-assisted flow calibration” in the slicer. The P1S can do a basic flow calibration via the nozzle probe, but it is not as precise or dynamic.
3. Spaghetti detection. The camera plus LiDAR combination can detect when a print has failed catastrophically — the “spaghetti” of tangled filament you get when a print detaches from the bed and the nozzle keeps depositing material in mid-air. When detected, the X1C pauses and notifies you. The P1S can detect this via camera only, but the false positive rate is higher — it sometimes pauses good prints because the camera misidentified shadows as spaghetti.
4. Multi-material calibration. When printing with the AMS, the X1C uses LiDAR to calibrate the nozzle offset between color swaps, which improves color registration accuracy. For prints with fine color boundaries — a face with eye detail in a different color, for example — the X1C’s color transitions are tighter.
I want to be honest about this: the LiDAR is most valuable when it prevents a failed print. If you run your printer unattended for 8+ hour jobs regularly, catching a spaghetti failure and pausing automatically is genuinely useful — it saves filament, saves time, and prevents you from coming home to a printer that has been churning out plastic noodles for hours. If you babysit your printer, check on it frequently, or primarily do short prints, the LiDAR adds real but less dramatic value.
Print Quality Comparison
I ran both printers through the same test suite: calibration cube at 0.2mm and 0.12mm layer heights, a Benchy at standard speed (200mm/s) and fast (450mm/s), a demanding organic model (a bust with fine facial details), and a multi-color print with 0.4mm color boundaries.
At 0.2mm layer height, 200mm/s: Identical results. I photographed both prints in identical lighting and could not reliably identify which came from which printer. Dimensional accuracy was 19.96mm (P1S) vs 19.98mm (X1C) on a 20mm calibration cube — both excellent.
At 0.12mm layer height, 100mm/s: The X1C produced marginally cleaner results on the bust — fine hair detail was slightly crisper, and thin walls had marginally less variation. I want to be careful here: the difference was small enough that I could only reliably distinguish them when printing the same model side by side. A randomly presented photo of either would look excellent. The LiDAR-assisted flow calibration is doing real work here, but the P1S results are not bad — they are just slightly behind.
At 450mm/s: Both printers perform similarly. The X1C’s slightly better vibration calibration means overhangs on fast Benchys are a hair cleaner, but again, this is a marginal difference.
Multi-color at 0.4mm boundary resolution: This is where the X1C has the most visible advantage. On a two-color print with a fine text boundary in a contrasting color, the X1C’s color transitions had a maximum misregistration of about 0.2mm. The P1S showed 0.3-0.4mm misregistration on the same model. This matters for high-resolution multi-color prints — logos, fine text, small color detail. For large-format multi-color prints (a three-color vase, a four-color dragon model), both look equally good.
The honest assessment: The X1C produces better prints than the P1S on demanding technical use cases — fine detail, tight multi-color registration, long unattended prints. The P1S produces excellent prints that most users would call perfect. The gap narrows further once you tune the P1S’s manual calibration settings.
Multi-Material and AMS Performance
Both printers use the same AMS (Automatic Material System) hardware, which holds four spools and manages filament loading, switching, and runout detection. The AMS is not included at the base price — you buy the “combo” package ($1,049 P1S, $1,249 X1C) or add an AMS unit ($349) separately to either printer.
The AMS system is the same hardware regardless of which printer you attach it to. Where the X1C has an advantage is in the calibration between color swaps — the LiDAR measures nozzle offset after each filament change and adjusts placement accordingly. This improves color registration on fine-detail prints as I mentioned above.
Multi-material failure rates — jams, failed swaps, tangled filament — are similar on both printers. The AMS itself is the constraint here, not the printer. I have had jamming issues on both with certain filament brands that have dimensional variation (cheap filament tends to vary in diameter, which confuses the AMS sensor). Bambu’s own filament and Polymaker are the most reliable; I have had occasional issues with Amazon Basics PLA and off-brand spools.
If you are running four AMS units (16 colors, which is possible with both printers via the AMS Hub), the X1C’s LiDAR-assisted calibration becomes more valuable because the nozzle offset compounds over multiple swaps. For single AMS four-color printing, the advantage is smaller.
Verdict: If multi-material printing is a primary use case and print quality on fine boundaries matters, the X1C is worth the premium. For general multi-color printing with large color areas, the P1S is sufficient.
What the X1C Does NOT Do That You Might Expect
A few things I want to clarify because the marketing implies capabilities the X1C does not actually have.
The LiDAR does not prevent all failures. It detects and responds to certain failure modes. A print can still fail from a nozzle clog, a bad filament splice from the AMS, a model that was sliced incorrectly, or mechanical issues. Spaghetti detection catches one specific failure mode — model detachment. It will not catch a partial clog that causes under-extrusion across 10 layers, and by the time those layers look bad on camera, significant material has been wasted.
The AI calibration is a starting point, not a substitute for tuning. The X1C’s LiDAR-assisted flow calibration runs a quick scan and sets a baseline. For demanding technical prints or new filament, I still run manual calibration towers in OrcaSlicer for temperature and retraction. The X1C gets me 80% of the way there automatically; the remaining 20% is still manual.
The X1C does not print faster than the P1S. Same motion system, same acceleration, same nozzle temperatures, same maximum speed. The marketing sometimes implies the X1C is the performance machine and the P1S is the compromise. They are identical on speed.
Warranty and support are the same. Both printers have one-year warranty. Both have the same support response times from Bambu. The X1C does not get priority support.
Who Actually Needs the X1C
After running both printers, here is the honest use case breakdown:
The X1C is the better choice if:
- You run the printer unattended for long prints (6+ hours) and cannot check on it regularly. Spaghetti detection with auto-pause is a genuine quality-of-life improvement in this scenario.
- You print with multiple AMS units or frequently do high-resolution multi-color work where color registration accuracy matters at the sub-millimeter level.
- You print demanding engineering filaments (TPU, nylon, PETG in thick cross-sections) where precise flow rate matters for dimensional accuracy. The LiDAR’s real-time flow adjustment helps here.
- You want minimal manual calibration and are willing to pay for it. The X1C gets to a good first print faster than the P1S on a new filament — the P1S is close but needs a bit more manual tuning to match.
- You are running a small production operation where a single caught failure pays for the price difference over time.
The P1S is sufficient if:
- You are a hobbyist who prints for fun and are around during prints.
- You primarily print single-color or low-resolution multi-color models (large color areas, not fine text or logos).
- You print PLA, PETG, and ABS primarily — materials that are well-understood and rarely have unexpected flow issues.
- You are comfortable running the basic manual calibration in Bambu Studio.
- The $200 difference matters to your budget. If you are on the fence, the P1S savings buys 10kg of premium filament.
Real User Complaints
From the Bambu Lab Community Forum and r/3Dprinting, here are the complaints I see repeatedly for each printer:
P1S complaints:
- “I wish it had spaghetti detection — came home to a 7-hour job that failed at hour two”
- “The flow calibration needed manual tweaking for every new PETG spool — the automatic calibration isn’t great for PETG”
- “Honestly I feel like I paid $700 for a P1P with a box around it” — a fair point from longtime Bambu users who feel the P1S should have the X1C’s LiDAR at its price point
X1C complaints:
- “The LiDAR triggers false alarms on some transparent filaments — it reads through the material and gives incorrect readings” (known issue, firmware partially addressed it but it still happens occasionally)
- “The spaghetti detection paused a perfectly good print on a fuzzy skin model — the algorithm misidentified the texture as spaghetti” (uncommon but happens with certain model types)
- “It’s $200 more than the P1S and the only real difference is the LiDAR — feels overpriced for what it adds”
- “X1C carbon fiber plate included is nice but the PEI plate from the P1S is actually what I use 95% of the time”
Companion Products for Both Printers
Both printers use the same accessories. Here is what I run with my enclosed Bambu machines:
- Bambu AMS ($349 standalone, or buy the combo) — Check price on Amazon — The feature that makes these printers special. Four colors, automatic spool management, runout detection. Essential for multi-color work.
- Bambu Hardened Steel Nozzle 0.4mm ($15) — Check price on Amazon — Required if you print carbon fiber, glow-in-the-dark, or other abrasive filaments. The stock brass nozzle wears in 500-800g of abrasive filament.
- HEPA + Carbon Filter Replacement ($15-20, buy a 3-pack) — Check price on Amazon — Replace every 2-3 months with heavy use. Do not skip this if you print ABS — the carbon filter is what keeps your room from smelling like a plastic factory.
- Bambu Cool Plate (smooth PEI) ($25) — Check price on Amazon — The textured plates are great for PLA; the cool plate is better for PETG and TPU. Having both makes material changes faster.
- Polymaker PolyLite ASA ($22/kg) — Check price on Amazon — Now that you have an enclosed machine, use it to print ASA for outdoor parts. It UV-stable and heat-resistant in a way PLA simply is not.
- Bambu AMS Hub ($50) — Check price on Amazon — If you run two or more AMS units (8+ colors), the hub connects them and manages routing. Worth having if you are serious about multi-color.
- USB-A drive ($8-12) — Check price on Amazon — For offline printing without cloud. Have one formatted and ready before you need it.
- SUNLU S2 Filament Dryer ($40) — Check price on Amazon — Even with an AMS managing spools, nylon and PC filament absorb moisture faster than the AMS cycling keeps them dry. A dryer for engineering filaments is worth it.
The Final Verdict
The P1S is the right choice for most buyers.
At $699 (or ~$1,049 with AMS combo), it is a fully enclosed, high-performance CoreXY printer with the same build volume, print speed, materials capability, and AMS compatibility as the X1C. For hobbyists, designers, cosplayers, small business prototyping, and anyone printing in a monitored environment — the P1S does everything they need.
The X1C at $899 (or ~$1,249 with AMS combo) is the right choice if you are in a specific subset: you run long unattended prints regularly, you do high-resolution multi-color work with fine detail, or you print demanding engineering filaments and want the best automatic calibration available. These are real use cases, and for those users the X1C’s advantages are genuinely worth $200.
If you are genuinely uncertain whether you need the X1C features, you do not need them yet. Start with the P1S. The community has extensive P1S calibration resources, the print quality is excellent, and if you eventually find yourself wanting spaghetti detection and LiDAR-assisted calibration — you can sell the P1S for 60-70% of its value and upgrade. Bambu printers hold their resale value reasonably well.
The one scenario where I recommend the X1C without hesitation: if you are buying the AMS combo and planning to do serious multi-color printing from day one, the $200 difference in a $1,249 purchase is a relatively small percentage, and the improved color registration on the X1C is meaningful for that use case.
If I Were Spending My Own Money Today
For most hobbyists: P1S. $699 standalone or ~$1,049 with AMS. The print quality is excellent, the software ecosystem is the best in the industry, and the enclosed chamber opens up materials that open-frame printers cannot touch. Check price on Amazon
For production users or serious multi-color work: X1C. $899 standalone or ~$1,249 with AMS. The LiDAR-assisted calibration and spaghetti detection pay for themselves if you run the printer heavily. Check price on Amazon
If you are on a tight budget and considering the enclosed Bambu tier: The P1S is the better value. Spend the $200 savings on filament, an AMS, or a nozzle upgrade kit.
Both printers are excellent. Either choice is a good one. The question is just how much you are going to use it.
