Short answer: Only sometimes. A Bambu Lab A1 enclosure helps with drafts, dust and noise, but it does not turn the A1 into a high-temperature printer.
For PLA and PETG in a normal room, most people can skip it.
Who This Review Is For
You own an A1, or you are about to buy one. Someone in a forum said "just add an enclosure," and now your wallet is nervous.
This review checks what the enclosure can and cannot change. It relies on published specs and retailer pages, not on guesses.
- Best fit: A1 owners in cold, drafty or dusty rooms.
- Also useful: Anyone weighing an enclosure against a different printer.
- Not covered: Lab-style hands-on test data. I have not printed on your machine, and I will not pretend otherwise.
What the Bambu Lab A1 Is Built For
The A1 is an open-frame printer. Polymaker's printer wiki says it has no heated chamber and suits standard filaments.
Bambu Lab's own A1 technical specifications confirm the key numbers.
| Spec | Value |
|---|---|
| Build volume | 256 × 256 × 256 mm |
| Max hot end temperature | 300 °C |
| Max build plate temperature | 100 °C |
| Ideal filaments | PLA, PETG, TPU, PVA |
| Not recommended | ABS, ASA, PC, PA, PET, carbon or glass fibre reinforced polymers |
Notice the last row. Bambu Lab already tells you which materials the A1 is not meant for.
What an Enclosure Can Actually Do
An enclosure is a box around the printer. It is not a heater and it is not magic.
Here is what a box can reasonably help with:
- Drafts: Cold air from a window or door can disturb a print.
- Dust: A closed front keeps the build area cleaner.
- Curious hands and pets: A door is a polite "please don't touch."
- Sound: Some panels dull noise a little. Results vary by design.
Here is what it cannot fix:
- It does not add a heated chamber.
- It does not raise the A1's rated limits.
- It does not make the A1 a match for an enclosed machine.
Does PLA or PETG Need an Enclosure on the A1?
No, for normal indoor use. Bambu Lab lists both as ideal for the A1.
A print guide from GoodPrints3D says the open frame is usually fine for ordinary PETG. The same page tells buyers to check cold or drafty locations first.
| Situation | Enclosure worth it? | Why |
|---|---|---|
| PLA in a normal room | Probably not | Listed as ideal by Bambu Lab |
| PETG in a normal room | Probably not | Listed as ideal by Bambu Lab |
| PETG in a cold or drafty garage | Maybe | Drafts are the risk, per GoodPrints3D |
| Dusty workshop | Maybe | A door keeps the bed cleaner |
| ABS or ASA | No | Bambu Lab does not recommend them for the A1 |
| Nylon or carbon fibre blends | No | Also on the not-recommended list |
Does It Make Printing Easier? A Scorecard
Ease is not one thing. So here is the breakdown.
- Setup: Harder. You add assembly and must leave room for the toolhead and bed to move.
- Daily use: Mixed. A door helps with dust, but you open it to swap plates and check parts.
- Print reliability in a stable room: About the same.
- Print reliability in a drafty room: Likely better.
- Material range: Unchanged. The A1 still has no heated chamber.
So the honest verdict is "easier in specific rooms." It is not "easier for everyone."
What Does an A1 Enclosure Cost?
Bambu Lab does not sell an official A1 enclosure. Clearview Plastics, a third-party seller, lists its A1 Enclosure Kit at $369 USD and says it is sized for the A1.
Prices change, so check the seller's page before you buy.
Now compare that to buying a printer that is enclosed from day one. A price listing on BambuHub puts the enclosed P2S at $549. It also notes that the P2S has an activated carbon filter.
| Path | Listed price | Best for |
|---|---|---|
| A1 plus third-party enclosure | $369 for the enclosure, on top of the printer | Owners who already have an A1 and a draft problem |
| Bambu Lab P2S | $549 | Buyers who want an enclosed printer from the start |
Prices come from the linked seller pages and may have changed. Bundles and taxes are not included.
Buy It or Skip It?
Buy an enclosure if:
- Your printer sits near a window, door or vent.
- Dust keeps landing on your build plate.
- Kids or pets keep visiting the printer.
Skip it if:
- You print PLA or PETG in a stable indoor room.
- You hope it will unlock ABS or ASA. It will not.
- You would rather spend the money on filament.
If you truly need engineering filaments, consider an enclosed printer instead.
Small Room Tips Before You Spend Anything
Try free fixes first. They cost nothing and take a minute.
- Move the printer away from open windows.
- Close the door of the room during long prints.
- Wipe the build plate before each job.
- Give the machine breathing space, and check our guide to smart storage for limited space.
- If noise is the real issue, see how a busy household can still sleep well.

Frequently Asked Questions
Does the Bambu Lab A1 come with an enclosure?
No. It is an open-frame printer with no heated chamber.
Can the A1 print PETG without an enclosure?
Yes. Bambu Lab lists PETG as ideal, and PETG does not normally require an enclosure.
Can an enclosure let the A1 print ABS or ASA?
Not reliably. Bambu Lab lists both as not recommended, and a box adds no chamber heater.
Is a third-party enclosure covered by Bambu Lab?
I found no official Bambu Lab enclosure for the A1. Check the seller's warranty terms, such as the one-year defect warranty Clearview Plastics lists.
Final Verdict
An A1 enclosure makes printing easier in drafty, dusty or busy spaces. In a calm room with PLA or PETG, it mostly adds cost and a door to open.
Buy it to fix a real problem. Do not buy it hoping for a new printer.
