Enclosures
Enclosures for the A1 and A1 mini
The open frame is the A1's one real limit. An enclosure narrows it, and being honest about how far is the point of this page.

What your options actually are
A fabric enclosure tent. Cheapest and the sensible default. Delivers flame retardancy, dust exclusion, some quiet, and more stable temperature. Does not deliver reliable ABS.
A purpose-built acrylic or polycarbonate enclosure. Holds heat better, costs more, and does not fold away. Clearview Plastics is one option cited for the A1 specifically, with AMS compatibility that needs no rewiring.
A DIY build — a cabinet, acrylic sheet, printed brackets. Cheapest per volume, most work, and completely legitimate. The DIY guide.
The measurement people get wrong
Measure the printer with the AMS Lite fitted, and allow clearance above for the spools to turn freely. An A1 with four spools on top is dramatically taller than an A1, and this is the single most common cause of a returned enclosure.
Also check: can you open the door and remove the plate without lifting the printer out? And is there room for the filament path to leave the enclosure without a tight bend, which adds drag and causes feed problems? Both are easy to overlook on a diagram and obvious the first time you use it.
What an A1 enclosure realistically delivers
| Goal | Realistic outcome |
|---|---|
| Print ABS reliably | No. Passive fabric cannot reach the chamber temperature ABS wants. |
| Print large PETG without warped corners | Yes, noticeably. This is the main print-quality win. |
| Keep dust off the plate | Yes, completely. |
| Quieter machine | Somewhat. Airborne noise drops; vibration through the desk does not. |
| Fire containment | A flame-retardant lining is a genuine safety benefit. |
| Protect filament from humidity | No. That is a dryer and sealed storage, not an enclosure. |
If ABS is the whole reason you are here
Then be honest with yourself about the arithmetic. A fabric enclosure gets you part of the way, and an enclosed machine gets you all of it. If ABS and ASA are central rather than occasional, the money is better spent on an enclosed printer than on a box plus continued frustration — A1 vs P1S and upgrading from an A1.
If ABS is occasional, the enclosure is the right call and the ABS guide will get you further than a bigger box would.
What it will not fix
Open-air AMS Lite spools absorbing moisture. An enclosure is not a dry box — it has no desiccant and no heater, and in a humid room the air inside it is as damp as the air outside. If your prints are stringing or your TPU is brittle, the answer is a dryer, not an enclosure.

1. Best A1 enclosure for the money
Comgrow 3D Printer Enclosure
Flame-retardant lining, real temperature stabilization, and folds away when you do not need it.
A fabric enclosure on an iron frame with a flame-retardant aluminum lining and a 600D Oxford shell, cited as waterproof and dustproof, with dust reduction, noise reduction, temperature stabilization and tool pockets.
For an A1 this is the sensible default. The realistic wins are fewer warped large PETG parts, no dust on the plate, a quieter machine and a flame-retardant barrier around something that runs unattended. All four are worth having and none of them is ABS capability.
Measure your printer with the AMS Lite fitted before ordering. That is where this purchase goes wrong.
What it gets right
- A flame-retardant lining on a machine that runs unattended overnight is the kind of upgrade you do not regret
- Stabilizes temperature enough to cut warping on large PETG parts, which is the realistic win here
- Collapses and stores, unlike an acrylic box
What it does not
- It reduces noise; it does not soundproof. Expect a difference, not silence
- Fabric and a passive frame will never give you a 60 C chamber — this is not an ABS solution
- Listed compatibility is written around Creality-sized machines, so measure your printer and your AMS before buying
| Type | Fabric enclosure tent with an iron frame |
|---|---|
| Interior | Flame-retardant aluminum lining |
| Outer shell | 600D Oxford fabric, waterproof and dustproof |
| Features cited | Dust reduction, noise reduction, temperature stabilization, tool pockets |

2. Best if the AMS has to fit inside too
Creality Fireproof 3D Printer Enclosure
Available large enough for an A1 plus four spools, which the printer-shaped boxes are not.
Same category, bigger sizes. An A1 with AMS Lite on top is considerably taller than an A1, and a lot of enclosures sized for a printer simply will not close over the combination.
Stated as fireproof and dustproof with constant temperature regulation, with cited benefits of better bed adhesion at high temperature and reduced warping. The clear window is practically useful for checking a first layer without opening up.
Verify internal dimensions rather than trusting a compatibility list written around Creality machines, and leave the ventilation as designed.
What it gets right
- Available in sizes large enough to swallow a printer and a four-spool unit, which the printer-shaped boxes cannot
- Same flame-retardant safety argument as any good fabric enclosure
- A clear window panel means you can still watch a first layer
What it does not
- Large enclosures trap heat around electronics as well as around the print — leave the vents alone
- Compatibility lists are written for Creality machines; verify internal dimensions against your own printer
- A passive tent cannot replace an actively heated chamber for ASA
| Type | Fabric enclosure with frame |
|---|---|
| Claims cited | Fireproof, dustproof, constant temperature regulation |
| Stated benefits | Better bed adhesion at high temperature, reduced warping |
Questions people actually ask
Does the Bambu Lab A1 need an enclosure?
Not for PLA and PETG, which is what most A1 owners print. It is worth having for dust exclusion, flame containment and fewer warped large PETG parts, and it is required if you want to attempt ABS or ASA at all - though a passive box will not make those reliable.
What size enclosure do I need for an A1?
Measure the printer with the AMS Lite fitted, and allow clearance above for the spools to turn. An A1 with four spools on top is much taller than an A1 alone, and that is the single most common reason an enclosure gets returned.
Can I print ABS in an A1 with a fabric enclosure?
Small parts, sometimes. Tall parts, not reliably. A passive fabric box traps heat the bed produces rather than creating chamber heat, so it cannot reach the temperature ABS wants. If ABS is central to what you do, an enclosed machine is the honest answer.
Will an enclosure keep my filament dry?
No. An enclosure has no desiccant and no heater, so the air inside it is as humid as the air outside. Filament protection is a dryer plus sealed storage, which is a separate purchase from an enclosure.
Is a DIY cabinet enclosure as good as a bought one?
Often better per unit of volume, and plenty of A1 owners do it. The three things to get right are ventilation for the electronics, a shelf dense enough not to amplify vibration, and access to the plate without lifting the printer out. Never seal it completely.
