Bambu Lab changed home 3D printing by making fast machines that work almost straight out of the box, with automatic calibration and an app that lets you start prints from your phone. If you are searching for a Bambu Lab enclosed 3D printer, you are probably wondering whether you need the enclosure at all, and which of the brand’s models actually have one.
In short, the P1S and P2S are enclosed, the A1 is an open-frame printer, and this list also covers the P2S Combo with its color-switching unit, a high-temperature filament dryer and Bambu’s own PLA filament.

What an Enclosed 3D Printer Does
An enclosure is a box around the printing area. It keeps warm air in and drafts out. That matters for materials like ABS and ASA, which can warp or crack when they cool unevenly. PLA, the most common beginner filament, prints happily on open machines. An enclosure also keeps curious hands and pets away from hot parts, and it can hold a filter to clean the air, which many families appreciate when the printer lives in a bedroom or office.

Bambu Lab P1S 3D Printer
Best for: Beginners wanting an enclosed printer for ABS
Pros
- Fully enclosed body
- Auto bed leveling
- Wide filament support
Cons
- Multi-color needs separate AMS
The Bambu Lab P1S 3D Printer is a fully enclosed FDM printer. FDM (fused deposition modeling) simply means it melts plastic filament and lays it down layer by layer. It lists speeds up to 500 mm/s with 20,000 mm/s² acceleration, automatic bed leveling and setup in about 15 minutes.
Bambu Lab lists ideal filaments as PLA, PETG, TPU, PVA, PET, ABS and ASA, with PA and PC as capable and carbon or glass fiber reinforced materials not recommended. It can print up to 16 colors, but only when connected to a Bambu Lab AMS, which is not part of this listing. The printer weighs 17.7 kg, so give it a sturdy table.
The P1S suits a beginner or hobbyist who wants the enclosure for ABS or ASA and is happy to print in one color at first. If you want the newer features and a heated chamber, look at the P2S. If you plan to print in ASA, our Bambu Lab ASA filament guide explains that material.

Bambu Lab P2S 3D Printer
Best for: Single-color makers wanting the newest enclosed model
Pros
- Up to 600 mm/s
- AI failure detection
- Adaptive airflow, carbon filter
Cons
- No multi-color without Combo
Best for: Families wanting multi-color prints from day one
Pros
- AMS 2 Pro included
- Filament drying to 65 °C
- 50 °C chamber with carbon filter
Cons
- Heaviest printer here
The Bambu Lab P2S Combo bundles the P2S printer with the AMS 2 Pro, a unit that holds several spools and switches between them for multi-color or multi-material prints. The AMS 2 Pro also dries filament at up to 65 °C, which helps because many filaments absorb moisture from the air and print poorly when damp.
The printer itself reaches up to 600 mm/s, using a PMSM servo extruder and active flowrate compensation for clean layers. AI failure detection watches for problems, quick-swap nozzles simplify maintenance, and calibration is automatic. The Adaptive Airflow System balances cooling for crisp overhangs, or keeps a 50 °C chamber for engineering materials, and a carbon filter cleans the air. You can print models from MakerWorld’s library of over one million designs using Bambu Studio and the Bambu Handy app. The combo weighs 46.3 pounds.
This is the most complete gift for a family or student who wants colorful prints without buying add-ons later. If one color is enough, the plain P2S saves space.
Bambu Lab A1 3D Printer for Beginners and Kids

Bambu Lab A1 3D Printer
Best for: Kids and beginners printing PLA
Pros
- Full-auto calibration
- Quiet operation
- Lightest printer here
Cons
- No enclosure described
- Multi-color needs AMS lite
The Bambu Lab A1 3D Printer is aimed at beginners and kids. It is an open-frame design, and its listing does not describe any enclosure. It offers 10,000 mm/s² acceleration, full-auto calibration including Z-offset and bed leveling, and active flow rate compensation.
A simple touchscreen, 1-Clip quick swap nozzle and quiet operation make it friendly for a home office or bedroom. Multi-color printing needs the AMS lite, which comes with the A1 Combo or separately. The listing weight is 10 kg, the lightest printer here.
Choose the A1 if you will mostly print PLA and want an easy, quiet first printer. For ABS or ASA, pick an enclosed P1S or P2S, since an open frame lets drafts reach the print.
Bambu Lab P2S 3D Printer for Single-Color Enclosed Printing
The Bambu Lab P2S 3D Printer is the same printer found in the Combo, without the AMS 2 Pro. You get up to 600 mm/s, the PMSM servo extruder, AI failure detection, quick-swap nozzles, automatic calibration, the Adaptive Airflow System with a 50 °C chamber and a carbon filter.
The listing states plainly that the P2S alone does not support multi-color printing. It weighs 38.9 pounds, and setup takes about 15 minutes.
It suits makers who print functional parts in a single color and want the newer enclosed platform. You can see how it fits with the wider lineup in our overview of Bambu Lab 3D printers.
High-Performance 3D Printer by Bambu Lab for Drying Engineering Filament
Best for: Owners printing moisture-sensitive engineering filaments
Pros
- 85 °C filament drying
- Bypass for soft filaments
- RFID auto-match drying
Cons
- Mislabeled as a printer
- Compatible printers not listed
Despite its title, the High-Performance 3D Printer by Bambu Lab listing describes the AMS HT, a filament storage, drying and feeding unit, not a printer. Its description calls it high-capacity, handling 24 colors and multiple materials.
It dries filament at up to 85 °C using an electromagnetic air vent and a rotating mechanism, and keeps spools in airtight storage. A bypass outlet helps with soft or brittle materials, a brushless servo motor feeds filament smoothly, and an RFID sensor auto-matches drying settings for official Bambu filaments. The listing does not say which printers it works with, and some specs, like supported file formats and a 1.21 kg weight, look copied from elsewhere.
This is an add-on for experienced owners printing moisture-sensitive materials such as PA or PC. First-time buyers should start with a printer.
Bambu Lab PLA 3D Printer Filament for Stocking Up
Best for: Stocking up any new Bambu Lab owner
Pros
- RFID auto settings
- Tight 1.75mm tolerance
- Reusable spool
Cons
- Single color per spool
The Bambu Lab PLA 3D Printer Filament is a 1kg spool of black PLA, 1.75mm in diameter with ± 0.03mm accuracy. A tight tolerance means the plastic feeds evenly, which helps avoid clogs.
An RFID tag lets Bambu Studio recognize the spool and set print settings automatically. It is AMS compatible and comes on a reusable spool, which cuts down on waste.
A spool or two makes a perfect add-on gift for anyone getting a new Bambu Lab printer.
How to Choose the Right Bambu Lab Printer
Enclosure or open frame. For ABS, ASA or engineering filaments, choose the enclosed P1S or P2S. For PLA-only printing, the open A1 is fine.
Single or multi-color. The P2S Combo includes its color unit. The P1S needs an AMS and the A1 an AMS lite. The plain P2S does not support multi-color.
Air quality. The P2S lists a carbon filter, useful for printers in living spaces.
Space and weight. The A1 is the lightest at 10 kg; the P2S Combo is heaviest at 46.3 pounds.

Can the P2S print in multiple colors?
Only with the AMS 2 Pro, which comes in the P2S Combo.
Is the AMS HT a 3D printer?
No. It is a filament drying and feeding unit, despite the listing title.
Which filament should a beginner use?
PLA. It is easy to print and works on every printer here.
Which Bambu Lab printer makes the best gift?
The P2S Combo is the most complete; the A1 is a friendly choice for kids who print PLA.
