Bambu X1C vs P1S: Same Prints, ~$600 Less

The X1C and P1S produce identical prints. Same motion system, same extruder, same speeds, same build volume, same filament capabilities in theory. If you hand me two benchies printed with the same filament and the same profile, one from each machine, I cannot tell you which came from which. Neither can anyone else who claims they can.

So why does the X1C cost almost twice as much? Because you are not buying print quality. You are buying a set of convenience features, a better camera, a touchscreen, and a scanner that watches your first layer for you. Whether those things are worth the $500-$700 gap depends on how you actually use a 3D printer, not on the spec sheet.

I run both printers on the 3DSearch test bench. They sit next to each other. When I need the same model printed twice for comparison, I can hit "print" on both at the same time and watch them finish within a minute of each other, with outputs that match up to my calipers. This guide is what I tell people when they ask me which one to buy, and I get that question a lot.

Print Quality: Genuinely Identical

This is the point the rest of the guide rests on, so it is worth repeating. Print quality between these two machines is indistinguishable. Same CoreXY motion system, same direct drive extruder, same stepper drivers, same input shaping algorithm, same build plate options. The mechanical hardware that determines print quality is, for all practical purposes, the same printer with different skin.

I have run side-by-side benchies, calibration cubes, and production parts on both. Surface finish matches. Dimensional accuracy matches. Overhang behavior matches. Layer adhesion matches. The only print-quality difference I can measure is that the P1S's open PLA printing runs slightly cooler in the chamber, which actually helps PLA surface finish on tall parts. That is a P1S advantage, not an X1C advantage.

3DPros ran a head-to-head comparison and reached the same conclusion. If print quality is your single priority, the P1S delivers 100% of the X1C's output at roughly 40% of the price.

If someone tells you the X1C prints better than the P1S with the same filament and settings, they are either selling you an X1C or they have never used a P1S.

Where the X1C Actually Wins

The X1C is not a scam. It has real advantages over the P1S. They just are not about print quality.

LIDAR scanning

The X1C's LIDAR module scans the first layer after it prints and detects under-extrusion, gaps, adhesion issues, and debris. It can pause the print and notify you before hours of filament get wasted. It also does spaghetti detection: if a print detaches from the bed mid-way, the LIDAR (combined with AI on the camera feed) catches it and stops the print.

In practice, this works about 90% of the time. It is not infallible. It will miss subtle issues that a trained eye would catch. It will occasionally false-alarm on prints that are actually fine. But for unattended printing, especially overnight, it is a real feature that the P1S simply does not have. If you start a print before bed and wake up to find the LIDAR caught a first-layer failure and paused at 2 AM, you immediately understand why this thing is worth money.

The enclosure

The X1C's enclosure is a genuinely different object than the P1S's. Aluminum frame, real glass top, tighter sealing, and an activated carbon air filter. The passive chamber temperature reaches 50-55°C during long prints, compared to the P1S's 40-45°C.

For PLA and PETG, this makes no practical difference. For ABS, ASA, nylon, and polycarbonate, it is the reason your part comes out without warped corners. The X1C's warm chamber is what makes high-temperature filaments reliably printable. See my ASA guide for why chamber temperature matters so much for these materials.

The camera

The X1C camera is 1080p at 30 frames per second. Smooth, usable video. You can watch a layer print in real time and notice issues as they happen.

The P1S camera is 720p at 0.5 frames per second. It is technically a camera and the images technically form a sequence, but calling it "video" is generous. You can see whether a print is generally still happening. You cannot see detail. You cannot catch issues before they become failures.

If you monitor prints remotely through the Bambu Handy app, the difference is larger in daily use than the spec sheet suggests. 3D Printed Decor's comparison highlighted the camera quality as one of the most immediately noticeable practical differences between the two printers, and I agree with that assessment.

Touchscreen and interface

The X1C has a 5 inch color touchscreen. The P1S has a 2.7 inch monochrome LCD operated with buttons. If you interact with the printer at the machine itself, the touchscreen is an obvious quality-of-life upgrade.

The catch: most people do not interact with their Bambu at the machine. They slice on a laptop, send via Bambu Studio or cloud, and check on prints through the Handy app. If that is your workflow, the display difference is almost invisible. If you walk up to your printer to do things, it is a real improvement.

Hardened nozzle and gears out of the box

The X1C ships with a hardened steel nozzle and hardened extruder gears. This means it can print carbon fiber composites (PA-CF, PLA-CF, PETG-CF), glass fiber composites (PA-GF), and glow-in-the-dark PLA without the nozzle eroding after 50-100 hours.

The P1S ships with stainless steel components. Stainless wears on abrasive filaments. You can upgrade the P1S nozzle to hardened for $10-$20 and the gears for similar. If you do not print abrasive filaments, the stock P1S parts are fine indefinitely.

Honest read: if you are planning to print carbon fiber composites regularly, the X1C's out-of-the-box readiness is nice. If you only occasionally print CF and do not mind a $20 upgrade and a ten-minute nozzle swap, the P1S is functionally equivalent.

Ethernet

The X1C has an ethernet port. The P1S does not. If your workshop has unreliable Wi-Fi, or you run a print farm where network reliability matters for uptime, ethernet is a real advantage. For a hobbyist with decent home Wi-Fi, it is irrelevant.

Air filtration

The X1C's activated carbon filter reduces ABS and ASA odor meaningfully. For PLA and PETG, neither printer needs filtration. If you print ABS frequently, the X1C's built-in filter is convenient. A $30-$50 standalone HEPA/carbon filter placed next to a P1S achieves comparable air quality.

What Most Comparison Guides Get Wrong

I've read a lot of X1C vs P1S articles. Most of them make the same few mistakes.

They act like the X1C prints better. It does not. This is measurable and not an opinion.

They treat LIDAR as a killer feature without caveats. LIDAR is useful. It is also wrong sometimes. It is not a substitute for checking on your printer.

They ignore that the X1C runs hotter internally, which is bad for PLA. An enclosed printer overheats PLA. The P1S enclosure vents better. For PLA-heavy users, this is actually a P1S advantage that never shows up in comparison tables.

They recommend the X1C to beginners. This is backwards. Beginners should buy the cheapest printer that meets their real needs, not the most expensive one. For most new users, that is the A1 Mini or the P1S, not the X1C.

They compare features in a vacuum. A touchscreen is only worth money if you use it. A 1080p camera is only worth money if you watch it. Ethernet is only worth money if you need it. The X1C's unique features are meaningful for a specific kind of user and meaningless for everyone else.

Unpopular opinion: the correct order of 3D printer upgrades for most makers is A1 Mini, then P1S, then X1C. Buying the X1C first is almost always spending money on features you haven't yet figured out you need.

Price Breakdown

As of April 2026, based on Bambu's US store and typical promotional pricing:

Configuration	X1C	P1S	Difference
Printer only	~$1,199	~$399-$449	~$750-$800
With AMS combo	~$1,199 (sale) - $1,449	~$599-$750	~$450-$700

The X1C combo has been available at $999-$1,199 during sales, which narrows the gap considerably. At sale prices, the X1C Combo becomes a much more defensible purchase. At MSRP, the P1S Combo is the clearer value.

What the extra money actually buys:

• LIDAR
• Better camera (real upgrade)
• Better enclosure (real upgrade for high-temp materials only)
• Touchscreen (nice to have)
• Ethernet (niche)
• Hardened components stock (~$20 P1S upgrade otherwise)
• Better air filtration (~$30 standalone filter otherwise)

What it does not buy:

• Better print quality
• Faster prints
• Larger build volume
• A different slicer
• A different app experience

Materials Support: Where the Gap Matters

Both printers technically support the same list of materials. In practice, the X1C handles some of them meaningfully better because of the enclosure.

Material	X1C	P1S	Winner
PLA	Good (open top)	Great	P1S
PETG	Great	Great	Tie
TPU	Good	Good	Tie
ABS	Great	Adequate	X1C
ASA	Great	Adequate	X1C
PA-CF	Great	Good (with upgrade)	X1C
Polycarbonate	Works	Struggles	X1C
PA-GF	Great	Good (with upgrade)	X1C

The pattern is clear: for everyday filaments, both printers are equal or the P1S is slightly better. For engineering filaments, the X1C is meaningfully better.

If your filament use is 80% PLA and PETG with occasional ABS, the P1S covers you. If you actually need ABS, ASA, nylon, and composites as part of your regular workflow, the X1C's enclosure earns its cost.

Common Buying Mistakes

Buying the X1C because "more expensive must be better." It is not in this case. It is different. The extras serve specific users.

Buying the P1S and discovering you needed a hardened nozzle. If you know you will print abrasives, either get the X1C or buy the $20 nozzle upgrade for the P1S the same day you buy the printer.

Buying the X1C Combo at full price when the sale price is available. Bambu runs sales frequently. If you can wait, wait. The $250-$400 discount is common.

Buying the P1S without the Combo and regretting it later. If you even think you might want multi-color, get the Combo. Upgrading the AMS later costs more than buying it upfront.

Buying either one without a filament dryer. PETG, ABS, ASA, nylon, and composites all need dry filament to print properly. A $50 dryer is a mandatory accessory, not an optional one.

Who Should Buy the P1S

The P1S is the correct answer for the majority of buyers. Pick it if:

• You print PLA and PETG 80%+ of the time
• You are usually around when the printer is running and can check on it
• You control your printer through Bambu Studio and the Handy app
• You are buying your first enclosed printer and want the best value
• You run a print farm where per-dollar output matters more than per-printer features
• You occasionally print ABS or nylon but it is not your main use case
• You want to save $500-$800 to spend on filament, a dryer, a good enclosure light, and a nicer nozzle

The P1S is my recommendation for 80% of the people who ask me this question.

Who Should Buy the X1C

The X1C earns its premium for specific workflows. Pick it if:

• You print carbon fiber or abrasive materials regularly and don't want to mess with nozzle swaps
• You run unattended or overnight prints often enough that LIDAR failure detection matters
• You print ABS, ASA, nylon, or polycarbonate as a main material and need the better chamber
• You monitor prints remotely and the camera quality is important to your workflow
• You run the printer as a business tool where reliability features reduce downtime
• You are operating in a workshop with flaky Wi-Fi and need ethernet
• You genuinely want the best and the price difference is not a concern

If two or more of these describe you, the X1C is the right call. If only one does, consider whether a targeted upgrade to the P1S (like a hardened nozzle) would solve it for less money.

Who Should Skip Both

Not every buyer should be looking at this comparison. Consider alternatives if:

• You are a beginner who is not sure what you want to print. Start with the A1 Mini. It is $219-$299, forgiving, and you will learn what you actually care about before dropping real money.
• You need a build volume larger than 256 mm. Neither printer has it. Look at the Creality K1 Max or the upcoming Bambu larger-format machines.
• You are philosophically opposed to Bambu's proprietary ecosystem. Prusa and Voron still exist. They cost more in time or money, but they are genuinely open.
• You need absolute silence. Neither of these is a silent printer. The A1 Mini in silent mode is quieter than both.

The Honest Recommendation

Buy the P1S. For the vast majority of users, the P1S delivers the same print quality as the X1C at roughly 40% of the price. Take the $500-$800 you saved and spend it on filament, a filament dryer, a good light, and a hardened nozzle upgrade if you ever need one. You will still come out ahead, and you will print exactly the same parts.

Buy the X1C only if you can point at one or more of its specific advantages (LIDAR, better enclosure, better camera, hardened components, ethernet) and say "yes, I need this for my actual workflow." If you are asking yourself whether you need those features, the answer is probably no.

Both machines are legitimately excellent. Both produce identical print quality. The P1S is the best value in enclosed 3D printing in 2026. The X1C is the best overall package for users whose workflow specifically benefits from its extras. Neither is a bad choice. The difference is about how much the extras are worth to you, not whether the extras exist.

Get Settings for Your New Bambu

Whichever you pick, start with the right slicer profile. My P1S PLA settings and X1C settings hub have the profiles I actually run on the 3DSearch test bench. For model-specific tuning, 3DSearch has an AI Settings feature: find any model, pick your printer and filament, and get a profile tuned for that model's geometry.

If you're still calibrating and hitting issues, the stringing fix guide and the best filament brands for 2026 roundup will save you time.

Both printers are great. The P1S is the smarter buy for most people. The X1C is the right buy for specific people. Now you know which one you are.
