Enclosures
Building your own enclosure
A cabinet, some acrylic and a few printed brackets gets you a real enclosure for very little. Three things decide whether it works.

The three things that decide whether it works
- Ventilation. Never seal it completely. Trapped heat around a power supply is a worse problem than a warped print, and it is the mistake that matters.
- A dense base. A hollow cabinet shelf acts as a soundboard and makes the machine louder, not quieter. Mass under the printer is what kills vibration.
- Access. You must be able to open it, remove the plate and reach the nozzle without lifting the printer out. If you cannot, you will stop using the enclosure.
What people actually build
A cabinet with an acrylic or polycarbonate front
The common approach: a sturdy cabinet of roughly the right size, a transparent front panel, and printed brackets to hold it. Cheap, rigid, holds heat well, and it looks deliberate rather than improvised.
Prefer polycarbonate over acrylic for the panel if you intend to run the chamber warm. Acrylic hazes and can craze with heat over time; polycarbonate tolerates it better — which is the same reason the replacement P1S door panels are polycarbonate.
A shelving unit with a fabric or acrylic surround
Faster and more flexible. Works well when the printer lives on a shelf anyway. Pay attention to the shelf material: thin particleboard spanning a wide gap flexes and resonates.
A frame-and-panel build
Aluminum extrusion plus panels, for people who enjoy that. Most expensive, most precise, and the easiest to vent properly because you control every opening.
Ventilation, in practice
The requirement is that heat generated by the electronics can leave. On a Bambu machine the power supply and mainboard are in the base, and the printer's own fans assume a path for air.
Practical approach: leave the printer's own vents unobstructed by at least a few centimeters of free space, and provide a low inlet and a high outlet in the enclosure so convection can move air. Do not point a fan at the print; that is cooling, and if you are enclosing for ABS you want less of it.
A fully sealed box that gets uncomfortably hot to touch at the base is telling you something. Listen to it.
Materials to avoid
- PLA for structural or heat-exposed brackets. It softens at chamber temperatures and a bracket that sags takes the panel with it. Print enclosure brackets in PETG at minimum, ideally ABS or ASA.
- Thin acrylic in a warm chamber. It hazes, and at thin gauges it can craze.
- Soft foam as the only insulation. Many foams are not flame retardant. Around an unattended machine that heats plastic to 260 C, that is the wrong material to economize on.
- Anything that blocks the exhaust path. Including, commonly, the back wall of a cabinet pressed against the printer.
Re-tune afterwards
A newly enclosed machine runs warmer. Expect more PLA stringing and softer overhangs, and expect to lower part cooling for ABS. That is the chamber working, not a fault — chamber temperature and the ABS guide.
And what it still will not do
Keep filament dry. An enclosure has no desiccant and no heater, so the air inside matches the room. If stringing or brittleness is the problem, that is a dryer.

1. The bought alternative, honestly
Comgrow 3D Printer Enclosure
If your DIY plan is costing more than this, buy this instead.
Worth pricing before you start. A fabric enclosure with a flame-retardant aluminum lining and a 600D Oxford shell on an iron frame already solves dust, flame containment and temperature stabilization, and it folds away.
DIY wins on volume per dollar, rigidity and the ability to fit your exact shelf. It loses on flame retardancy unless you choose materials carefully, which is the part most DIY builds skip.
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

2. Stop here if you own a P1P
Bambu Lab P1P Enclosure Kit
The manufacturer already built the thing you are about to approximate.
A P1P has an official enclosure kit. Building your own for that machine is solving a problem the manufacturer already solved, with engineered fit and airflow you cannot match in a cabinet.
DIY makes sense for an A1 or A1 mini, which have no first-party option.
What it gets right
- The only enclosure for a Bambu printer that the manufacturer designed, which means fit and airflow are not your problem to solve
- Cheaper than selling a P1P and buying a P1S
- Keeps the official support path intact, unlike a third-party box
What it does not
- P1P only. It does not fit an A1, an A1 mini or anything else
- The enclosure alone does not add the auxiliary fan and filter a P1S ships with — check what your kit includes
- Installation is an afternoon, not a minute
| Fits | P1P |
|---|---|
| Effect | Converts a P1P toward P1S specification |

Questions people actually ask
Can I put my 3D printer in an IKEA cabinet?
Yes, and plenty of people do - it is one of the cheapest routes to a warm, dust-free, quieter chamber. Get three things right: ventilation so electronics heat can escape, a shelf dense enough not to resonate, and access to the plate without lifting the printer out. Never seal it completely.
Do I need to ventilate a DIY enclosure?
Yes, always. The power supply and mainboard sit in the base of the machine and the printer's own fans assume a path for air. Leave the printer's vents clear and provide a low inlet and high outlet so convection can move air through. A sealed box that is hot to touch at the base is a warning.
What material should I print enclosure brackets in?
PETG at minimum, and ideally ABS or ASA. PLA softens at chamber temperatures, and a bracket that sags takes the panel with it. This is the one DIY mistake that fails slowly enough that people do not connect it to the material choice.
Is acrylic or polycarbonate better for an enclosure panel?
Polycarbonate if you plan to run the chamber warm. Acrylic hazes over time with heat and can craze at thin gauges, which is the same reason polycarbonate replacement door panels exist for the P1S. Acrylic is cheaper and fine for a dust-and-noise enclosure.
Will a DIY enclosure let me print ABS?
A well-built rigid enclosure holds heat better than a fabric tent and can get you reasonably far on small and medium parts. It is still a passive chamber, so tall parts remain the hard case. Pre-heat the chamber and lower part cooling before concluding the enclosure is at fault.
