Real-world performance

Who this is for

The verdict is to wait, and the reason is specific: the P2S is already shipping, so the P1S is the previous generation at a moment when its replacement is available now. That single fact reframes every buyer. If you are a first-timer, nothing about the P1S will trip you up. Setup is genuinely quick, the automation and error guidance carry you through, and you will very likely succeed with it. But you should still compare prices against the P2S before committing, because there is little reason to start a generation behind unless the P1S is meaningfully cheaper. A home hobbyist gains a real capability jump over open-frame PLA-only printing, with ABS, ASA, and flexibles in reach and multi-color available through the add-on, though that add-on is slow, purge-heavy, and wasteful, and it is multi-color rather than true multi-material, so cross-contamination limits mixed-material work. For a prosumer weighing this as a business tool, the support runway and parts availability are reassuring, but mixed durability reports and the fact that you are buying a discontinued generation both argue for looking at the successor first. The machine is good. The timing is the problem. Buy it only if it comes in far enough below the P2S to make a generation behind worth it; otherwise, put your money on the current model.

PrintSignals Review

Bambu Lab P1S Review

Written by AI from manufacturer specifications and the aggregated consensus of

PrintSignals does not test printers hands-on. How we do this

Assessment

The P1S is an enclosed, first-timer-friendly machine that reviewers consistently rate as fast, reliable, and capable of excellent output, and owners call it good value at its price of around €380. On its own merits it holds up well. The problem is timing. Bambu Lab is already shipping a direct successor, the P2S, which means buying the P1S now is buying a generation behind while the replacement sits on the shelf next to it. That is the one signal that should drive your decision. The firmware is still maintained and support commitments run for years yet, so this is not a dead machine, but you are committing to a superseded model. Before you buy, look hard at what the P2S adds and what it costs, because the case for the P1S rests almost entirely on whether it undercuts the newer model by enough to matter to you.

Build and print volume

You get a 256 by 256 by 256 mm build volume, a medium envelope that covers the large majority of what home users actually print: functional parts, enclosures, cosplay pieces built in sections, batches of smaller objects. It is not a large-format machine, so oversized single-piece prints are out, but few buyers in this class need that. The bigger hardware story is the full enclosure. It contains heat, which cuts warping and widens the reliable material range past what an open-frame printer can manage. The chamber is passively managed, meaning bed and motor heat raise the internal temperature but there is no dedicated heater to hold it at a set point, so actual conditions shift with your room and how long the print has been running. A direct drive extruder rounds out the hardware and is what makes flexible filament practical here.

Material capability

The reliable range covers PLA, PETG, PHA, PVB, ABS, ASA, and HIPS, and reviewers rate handling across that range as good in practice. The enclosure earns its place with ABS and ASA, giving a genuine edge over open-frame machines on warp-prone materials. That does not make them automatic: with only a passive chamber, larger parts still depend on a stable ambient temperature and some tuning, and the enclosure will help rather than guarantee. Flexibles are supported through the direct drive extruder, with TPU the most accessible; TPE, TPC, and PEBA are also within reach, but each one demands more tuning than the last. Two hard ceilings to know. The stock nozzle is stainless steel and not hardened, so abrasive materials require a hardened nozzle upgrade first. And carbon- or glass-filled nylons like PA-CF and PA-GF sit in advanced territory even after that upgrade, so treat them as a stretch, not a standard capability.

Setup and ownership

This is one of the easiest machines to get running that PrintSignals tracks. It arrives near-fully assembled, typically under 15 minutes from box to first print, and it handles bed leveling, Z-offset, and first-layer calibration automatically, with filament runout detection built in. When something goes wrong, on-screen QR codes link straight to the fix for that specific error, which is about the most actionable error guidance available. Day to day, reviewers rate it reliable, maintenance as manageable with clear procedures, the bundled camera as adequate for monitoring, and the manufacturer's slicer as good and well integrated. Two things to plan around. It runs noticeably loud, so a shared room or office is a real consideration, and fumes are noticeable during use while the enclosure seal is only partial, so ventilation matters even though the machine is enclosed. Failure detection is limited and misses some failure types, so do not treat it as a hands-off safety net. The printer alone is around €380; adding the multi-spool system brings it to roughly €560. One catch worth stating plainly: you are tied to Bambu Studio. The ecosystem is closed, third-party slicers are blocked, and OrcaSlicer has rejected the required integration, so Bambu Studio is your only slicing path.

Support and longevity

On paper the support picture is strong. Spare parts have comprehensive official availability, an extended warranty is offered, and the manufacturer's track record across warranty, official channels, and documentation is the strongest responsiveness pattern among the brands PrintSignals tracks, including publicly acknowledging hardware issues and shipping official fixes. Software support is committed through 13 July 2028 and security patches through 13 July 2030, so a prosumer buying today has a defined runway rather than a guess. Two counterweights. Firmware is maintained but no major new features are expected, which fits a model that has been superseded. And long-term durability reads as mixed, with some owners reporting component wear over time. Parts availability softens that risk, but it is the reason to think about how hard you plan to run the machine and for how long. The multi-spool add-on is rated mostly reliable, with occasional jams or swap failures.
