The Best Bambu Lab 3D Printers

That is the whole decision for most people. What follows is the reasoning, the four machines in the lineup that are not first printers, and an honest account of what we cannot tell you because we have not printed on any of them.

What Bambu Lab actually sells right now

This matters more than it should, because the brand releases fast and most of the recommendation lists you will find were written for a lineup that no longer exists. Read on 2026-09-04, Bambu Lab’s US store lists nine printers: the A1 mini, the A1 and the A2L in the open frame A series; the P1S and its replacement the P2S in the enclosed P series; the X2D; and the H2C, H2D and H2S at the top. Refurbished P1S and A1 units are listed separately.

The X1 Carbon is not on that list. For two years it was the machine every “best Bambu” article ended with, so if you land on a page that still recommends one, check the date at the top of it before you trust anything else it says.

Bambu Lab’s own store guidance is unusually blunt about who each machine is for: it points new buyers and schools at the A1 mini as the easiest starting point, calls the A1 and P1S the usual choices for people printing regularly, and says outright that the X2D and the H2 series are built for production and commercial demand. We agree with all of that, which is why this page covers five machines and not nine.

How we picked

Four criteria, applied in this order. They are the same criteria we use on the main beginner roundup, narrowed to one brand.

1. Does it calibrate itself, and is that documented? The three steps that historically ended first attempts are bed leveling, the Z-offset and flow. Every machine on this page automates all three, and Bambu Lab publishes what it automates rather than leaving you to infer it from a marketing video. On the P2S, for example, Bambu Lab’s own manual lists auto bed leveling, high-temperature bed leveling, vibration compensation and nozzle offset calibration by name, and says a faster leveling pass can run before each job.

2. Is the build volume honest for what a first year makes? Volume is the specification people over-buy on hardest. We rank a machine down for size it cannot heat properly and up for a plate that matches its material list.

3. Does the material list match PLA? Your first year is PLA, whatever you currently believe. A machine rated ideal for PLA and PETG is doing its job; a machine that can also run PA and PC is selling you capability you will not use for a long time.

4. What does multi-color actually cost? No Bambu printer prints in more than one color out of the box. The AMS is a separate purchase on every model here, and the Combo bundles are the honest way to compare prices between brands.

One thing we deliberately do not weigh: our own opinion of print quality. We have not run a single print on any of these machines and say so on every page. Everything above is read from Bambu Lab’s published specifications, and the how we pick page sets out exactly what that method can and cannot support.

Three questions that decide which Bambu

How big is the biggest thing you can name? Not imagine — name. The lineup steps 180 mm, then 256 mm, then 330 x 320 x 325 mm. Most first-year printing is desk-sized objects that fit comfortably inside the smallest of those, which is why the A1 mini leads this page rather than the biggest machine in it.

Do you need ABS or ASA, or does it need to be quiet? These are the two reasons to buy an enclosure and they are the only two. Bambu Lab rates the entire A series as unsuitable for ABS, ASA, PC and fiber-reinforced filaments, so no amount of extra build volume in the open-frame range gets you those materials. If a specific project demands them, or if the printer has to run overnight in a room somebody sleeps in, you are in the P series. Our A1 against P1S comparison walks that decision through in detail.

Do you want more than one color on day one? If yes, budget for the Combo rather than the base machine. If you are not sure, buy the base machine — the AMS can be added later, and the multicolor roundup explains the purge waste that comes with it before you commit.

Where the A series and the P series really differ

Two things, and only one of them is about plastic.

The box. An enclosure holds chamber heat, and chamber heat is what stops ABS and ASA peeling off the plate as they cool and contract. It also contains most of the noise and most of the smell. That is the whole benefit, and it is a large benefit to the small number of people who need it.

The motion system. The A series moves the plate back and forth under a head that travels in one axis. The P series keeps the plate still and moves the head in two — CoreXY — which is how it reaches twice the published acceleration of an A-series machine. For a beginner this is a speed difference, not a difficulty difference. Nothing about a P1S or a P2S is easier to learn on than an A1 mini.

The row worth staring at is the A2L’s plate temperature. It is the biggest machine here and it heats to the same 80 C as the smallest, 20 C below the A1 it sits above in the range. Large parts in PETG want a warm plate to stay put, so the extra volume is genuinely most useful in PLA. That is not a defect — it is a machine built to print big PLA objects in one piece, and it does not pretend otherwise in its own material list.

P1S or P2S, if you have decided on an enclosure

Both are enclosed, both give you 256 mm cubed, and both automate the same setup steps. The P2S adds a 110 C plate rather than 100 C, a rated 40 mm3/s flow, a 600 mm/s head, an airflow system Bambu Lab says draws cool air from outside the chamber so low-temperature filaments can be printed with the door closed, and a filter it rates for VOC and particulate filtration.

Those are real improvements and none of them changes what a first year looks like. The P1S is currently the cheaper way into an enclosure and is still listed new, alongside factory refurbished units that Bambu Lab sells with the same warranty as new. If the enclosure is the whole reason you are shopping in this band, the older machine is the buyer-first answer for as long as it is stocked. If you are buying once and keeping it for years, buy the P2S and stop thinking about it.

The prices on both move constantly, and one of them has been discounted heavily since its replacement launched. That is exactly why we do not print a number in this text: the live price sits inside every buy button on this page and it is the one that counts.

One more option worth knowing about, and it is not one we can sell you: Bambu Lab lists factory refurbished P1S and A1 units in its own store, at refurbished prices and, it says, with the same warranty as new. The buy buttons on this page go to Amazon, so if a refurbished machine is what you want, that is a purchase to make direct with the manufacturer. We would rather tell you that than pretend the only route is the one we earn on.

The four machines we did not pick

The X2D is a dual-nozzle printer, and the H2C, H2D and H2S sit above it — larger, and in the H2D’s case a machine that also takes a laser module and a cutting blade. They are interesting and they are not first printers, for a reason that has nothing to do with quality: a second nozzle and a laser are two more systems to learn at the exact moment you are still learning what a first layer should look like. Bambu Lab positions this end of its own range at production and commercial use, and we take the company at its word.

If you are drawn to them anyway, the honest test is whether you can describe a job you have today that needs two materials at once. If you cannot, that money buys a great deal of filament and six months of practice on an A1, which is a faster route to good prints than any machine upgrade.

What we could not check

Everything above is a published figure or a published claim. Here is the list of things that decide whether you like a printer and that no specification page can tell either of us.

Noise, honestly measured. Bambu Lab does not publish a decibel figure for these machines, and “quiet” in a workshop and “quiet” in a bedroom are different words. An enclosure helps. How much, we cannot tell you.

How often the automation needs a human. Every machine here calibrates itself. Whether that means never touching it for a year, or re-running a leveling pass every few weeks, is exactly the sort of thing you learn by owning one for a year.

Long-term reliability. The P2S has a new servo extruder and the A2L a new damping system, and both are too recent for anyone to have honest multi-year data on. Treat any page that claims otherwise with suspicion, including ours if we ever do it.

Whether the AMS jams in your house. Bambu Lab cites a very large number of users as evidence that it does not. That is a reasonable thing for them to say and not a substitute for a spool of third-party filament in your own machine.

What you still have to do yourself

Self-calibration removes the setup steps that used to defeat people. It does not remove the first week. You will still choose where the machine lives, still learn what a good first layer looks like, and still hit the ordinary problems every printer has, so it is worth reading the setup guide before the box arrives rather than after. A machine that levels its own bed is a machine that fails less often, not one that never fails.
