Direct answer: yes, the Bambu Lab P1S is still worth it in 2026 when its like-for-like landed savings exceed the cost of any required hardware and the real value of P2S ownership refinements. Buy the P2S when the normalized gap is small and you will use its hardened-steel nozzle and extruder gear, quicker nozzle service, improved camera and controls, error detection or adaptive airflow. Neither printer gives you more than the same published 256 x 256 x 256 mm build volume.
Current-owner verdict: keep a reliable P1S when it meets accepted-part quality, material, uptime and throughput requirements. Upgrade only when a named P1S limitation is creating recurring rejects, operator time, service delay, monitoring gaps or added hardware cost. A newer model year is not a production requirement.
| P1S worth-it check | P1S | P2S | Decision rule |
|---|---|---|---|
| Published volume | 256 x 256 x 256 mm | 256 x 256 x 256 mm | Do not pay for P2S expecting more build room. |
| Stock extrusion path | 0.4 mm stainless-steel nozzle listed | 0.4 mm hardened-steel nozzle and hardened-steel extruder gear listed | For abrasive composites, price the complete qualified P1S hardware path against P2S. |
| Ownership refinements | Established enclosed single-nozzle workflow | Quicker nozzle service, improved camera and controls, error detection and adaptive airflow | Value only features that reduce measured labor, rejects, service time or monitoring risk. |
| New-buyer rule | Buy at a meaningful normalized discount | Buy when the remaining premium is justified | Match printer-only or comparable AMS bundles, then add required hardware, shipping, tax, warranty and return differences. |
| Current-owner rule | Keep when accepted output is reliable | Upgrade for a documented recurring bottleneck | Run the same ten repeat jobs before replacing a working production cell. |
Normalize the carts before choosing. Use the P1S vs P2S comparison for the complete new-buyer decision and the P1S-to-P2S upgrade test if you already own one. The P1S materials guide explains hardware and process boundaries, the P1S review covers the full ownership case, and the P1S alternatives guide routes larger, actively heated or different-ecosystem requirements.
Source and disclosure: current size and stock-hardware posture were rechecked September 1, 2026 against Bambu Lab's P1S page and P2S page. Prices, bundles and availability vary by region and time, so the verdict uses a same-day normalized-cart test rather than a fabricated universal price threshold.

P1S worth-it verdict by buyer
| Buyer | Best move | Reason |
|---|---|---|
| First enclosed-printer buyer seeing a deep P1S discount | Buy the P1S | You retain the full-size enclosed Bambu workhorse lane without paying for improvements you may not use. |
| Buyer seeing a small like-for-like gap to P2S | Buy the P2S | The newer interface, camera, error detection, quick-swap nozzle, hardened extrusion path, and adaptive airflow can justify a modest premium. |
| Current P1S owner with reliable accepted output | Keep it | A generation change does not improve parts already passing your real requirements. |
| Frequent abrasive-composite user | Price P2S or the required P1S upgrades | The P1S currently lists a stainless-steel nozzle; the P2S lists hardened-steel nozzle and extruder hardware. |
| Buyer who needs dual-nozzle support-material workflow | Skip both | That is a workflow-class decision, not a reason to over-accessorize a single-nozzle P1S. |
What the P1S still gives you
Bambu Lab currently lists the P1S as an enclosed plastic-and-glass printer with a 256 × 256 × 256 mm build volume, an all-metal hotend, an included 0.4 mm stainless-steel nozzle, a 300°C maximum hotend temperature, a 100°C maximum build-plate temperature, and AMS compatibility. The maker labels PLA, PETG, TPU, PVA, PET, ABS, and ASA as ideal, with PA and PC in the capable category.
That is still a useful envelope for everyday fixtures, brackets, housings, prototypes, shop aids, and many short-run parts. The P1S has not become small because the P2S arrived, and Bambu's current P2S FAQ says there are no plans at the moment to stop selling the P1S.
The boundaries matter. An enclosure is not active chamber heating, a 300°C hotend is not automatic approval for every engineering filament, and a stainless nozzle is not the durable default for every abrasive composite. Use the P1S material-compatibility guide for exact filament and hardware decisions.
What you give up versus the P2S
The P2S is not larger: Bambu lists the same 256 mm cube. Its value is in daily interaction and current hardware. The official product page highlights a 5-inch touchscreen, higher-rate 1080p camera and lighting, AI error detection, automatic flow-dynamics calibration, quick-swap hotend, hardened-steel nozzle and extruder gear, adaptive airflow, and optional AMS 2 Pro drying.
Bambu also states that the P2S does not have active chamber heating. It manages temperature through its enclosure and an automatic circulation flap. That distinction prevents a common buying mistake: the P2S can be a better refined single-nozzle Bambu without becoming the answer to every heated-chamber or multi-toolhead job.
The deeper P2S versus P1S comparison owns the model-by-model decision. This page uses the shorter rule: P1S wins on a real discount; P2S wins when its ownership improvements solve recurring friction and the normalized gap is small enough.
Calculate the real price gap before choosing
- Match the configuration. Compare printer-only with printer-only, or normalize AMS and AMS 2 Pro bundles instead of comparing unlike boxes.
- Add required hardware. If the P1S needs a hardened hotend, spare surface, dryer, or another specific item for your workload, include it. Do not add accessories merely because they are popular.
- Include regional terms. Shipping, tax, warranty, returns, and current availability can move the real difference.
- Value only features you will use. Give the P2S premium weight only when the camera, interface, error detection, nozzle service, hardened extrusion path, or airflow reduces a real cost or annoyance.
- Divide the remaining gap by expected ownership. A modest difference over several years can be cheap; an unused feature remains expensive even when financed mentally across many months.
Do not copy a dollar threshold from an older review. Capture both carts on the same day, list the exact differences, and decide from the landed configuration.
If you already own a P1S, use an upgrade trigger
Keep the P1S when it is meeting accepted-part quality, uptime, volume, and material needs. Run the P1S-to-P2S owner decision only after you can name a recurring problem.
- Interface or monitoring trigger: remote checks, camera quality, or start-error detection is regularly consuming attention.
- Service trigger: nozzle changes or routine access are costing enough time to justify different hardware.
- Composite trigger: abrasive-material work is frequent enough that the stock P1S hardware path no longer makes operational sense.
- Workflow trigger: a single-nozzle machine is the wrong class for the supports, colors, materials, or throughput you now run.
- Reliability trigger: the current machine has a documented condition problem whose repair cost and downtime exceed the rational keep-it case.
Newness, a brighter screen, or resale anxiety is not an upgrade trigger by itself.
Run a ten-job proof before replacing a working printer
Review the last ten representative jobs rather than the last irritating print. Record accepted parts, restarts, operator minutes, material changes, nozzle work, drying delays, camera checks, maintenance, and reprints. Then label each loss as printer capability, material condition, slicing, geometry, maintenance, or operator process.
If the P2S would have prevented several repeated losses, price the change. If most losses came from wet filament, a poor model, worn consumables, or an unqualified profile, fix the process first. If the jobs require independent support material or genuinely different tools, use the X2D versus P1S workflow comparison instead of expecting a refined single-nozzle printer to change categories.
When another enclosed printer is the better answer
Choose a different branch when your decision is about ownership philosophy, repairability, chamber behavior, size, or multi-tool workflow rather than the P1S price. The Prusa CORE One versus P1S comparison covers the serviceability-first Prusa branch. The best P1S alternatives guide routes buyers who need a materially different enclosed-printer path.
Do not buy the P1S merely because it is discounted if the machine class is wrong. A bargain is still expensive when it cannot accept the parts, materials, process controls, or support workflow you need.
Who should buy the P1S in 2026?
- You want a full-size enclosed Bambu and the P1S is materially cheaper than a normalized P2S configuration.
- Your real work is PLA, PETG, ABS, ASA, and other materials that fit the documented machine and your qualified process.
- You value a mature, familiar platform more than the newer screen, camera, AI checks, quick-swap nozzle, and hardened stock extrusion path.
- You will add only the hardware your actual jobs require.
Who should skip it?
- The P2S is close in like-for-like landed cost and its improvements matter to your daily work.
- You expect frequent abrasive-composite printing but have not included the P1S hardware path in the comparison.
- You need active chamber heat, larger build room, independent support-material tools, or another capability outside the P1S category.
- You are replacing a good P1S without a measured quality, uptime, material, service, or workflow trigger.
Common questions
P1S worth-it questions that change the 2026 verdict
How much cheaper must the P1S be than the P2S?
There is no honest universal dollar cutoff. Compare same-day, like-for-like regional carts and subtract required P1S hardware plus the value of P2S features you will repeatedly use. The P1S wins when meaningful savings remain after that normalization.
Is P2S a build-volume upgrade over P1S?
No. Both publish a 256 x 256 x 256 mm build volume. Move beyond this pair when recurring complete layouts fail 256 mm after supports, purge structures, fixtures and safe clearance.
Is the stock P1S the better buy for carbon-fiber filament?
Do not assume so. The current P1S page lists a 0.4 mm stainless-steel nozzle, while P2S lists a hardened-steel nozzle and hardened-steel extruder gear. Qualify the exact composite, minimum nozzle diameter, feed path, drying, profile and ventilation, then price all required P1S hardware.
Should a current P1S owner upgrade to P2S?
Keep the P1S if it reliably passes the real queue. Upgrade only when the P2S changes a measured bottleneck such as nozzle-service time, abrasive-hardware cost, monitoring, error recovery, airflow-related consistency or operator interaction.
Is the P1S still a good ABS or ASA printer?
Its enclosure supports an enclosed-material workflow, but it does not make every ABS or ASA job automatic. Qualify the exact grade, drying, bed and nozzle setup, ventilation, geometry, warping, layer bonding and finished-part requirement.
Should I skip both P1S and P2S?
Yes when the recurring requirement is larger than 256 mm, needs active chamber control, independent tools, a different service model or another ecosystem constraint. Choose from the requirement rather than forcing every enclosed-printer decision into this pair.
Is the P1S discontinued?
No current official announcement says that. Bambu's P2S FAQ says there are no plans at the moment to stop selling the P1S, while telling buyers to watch official announcements.
Is the P1S build volume smaller than the P2S?
No. Bambu currently lists both at 256 × 256 × 256 mm. The P2S case is about refinement and hardware, not extra build volume.
Does the P1S ship with a hardened nozzle?
Bambu currently lists an included 0.4 mm stainless-steel nozzle. Price the exact hardened hardware and filament requirements before treating it as a recurring abrasive-composite machine.
Should a P1S owner upgrade to the P2S?
Usually not without a named trigger. Keep the P1S if it is producing accepted parts reliably; upgrade when monitoring, service, composite hardware, or another repeated limitation has a measurable cost.
Is the P1S still good for ABS and ASA?
Bambu lists ABS and ASA in the P1S ideal-material group, but the exact part, filament, ventilation, profile, build surface, chamber conditions, and acceptance test still control the result.
Bottom line
The Bambu Lab P1S is still worth it in 2026 as a discounted enclosed workhorse, not as the automatic current-default buy. Compare the same configuration on the same day. Choose the P1S when the savings are real and its older interface and stock hardware do not create a job-level penalty. Choose the P2S when the gap is modest and its refinements solve work you actually do. If you already own a healthy P1S, keep it until a measured limitation earns the upgrade.

If the P1S still wins, match the first add-on to the ownership friction you can name
The P1S does not become a better value because you surround it with accessories. It stays worth buying when the machine already fits your work and one specific ownership issue—not upgrade anxiety—is getting in the way. These are three separate branches, not a bundle.
If you want a ready spare surface for faster bed turnover
The IdeaFormer 257 x 257 mm textured PEI plate is the simple P1S/X1C-fit branch for swapping plates while one part cools or one surface gets cleaned. Confirm the listing's printer fit before ordering. The IdeaFormer plate review explains the spare-surface case.
Best first buy for routine P1S uptime; irrelevant if the stock plate is not slowing you down.
If wet PETG, TPU, or a long-open spool is being blamed on the printer
Polymaker PolyDryer is the one-spool dry-then-store branch. It can restore material discipline without pretending a dryer changes whether the P1S is the right printer. The PolyDryer review covers the workflow and limits.
Choose this for one active spool; do not stack it with another dryer just because both appear useful.
If you already own the P1S and easier hotend service is the real upgrade reason
The Micro Swiss FlowTech hotend listed for the P1P/P1S is the hardware branch to research before replacing the whole printer for nozzle-service frustration alone. It is not a default purchase and it does not add the newer machine features. Verify the exact P1S listing and installation requirements. The FlowTech P1S review explains who should consider it.
Owner-only branch: buy for a named serviceability need, not as automatic day-one gear.
Simple order: decide whether the P1S itself still fits. Then choose one fix: spare-surface uptime, one-spool moisture recovery, or owner-side hotend serviceability. If none is your actual problem, keep the money for the printer decision. If the real need is a limited run rather than owning this workflow, use the buy-versus-service checkpoint, then review JC Print Farm for production fit.
