Bambu Lab A1 Enclosure Kit

Clearview Plastics · Bambu Lab A1 and A2L Enclosure · Two sizes, one design

Nothing stands between your print and the room.

An A1 is an open-frame machine. There is no shell, no door, no filter — whatever comes off the plate goes straight into the air you are standing in, for the whole length of the job. On a CoreXY printer an enclosure is a second barrier around an existing one. Here it is the first, and the only.

The Clearview enclosure puts a defined volume around the machine, then gives that volume somewhere to send its air: filtered cool intake low, active exhaust high, and 120 mm ports that take any of our filters. On this design the intake is doing two jobs — feeding the filtration path and carrying cool air across the printer chassis. Bolt-on, CNC cut, 60 to 120 minutes to assemble, no modification to the machine.

The case for the first box

On an open-frame printer, there is no "contained" to begin with. Everything the print gives off is already in the room.

An enclosed machine at least holds heat around the print and slows what leaves. An open frame holds nothing. That makes the airflow design here more load-bearing than on any enclosed printer we build for.

GAP 01

There is no barrier at all

Off-gassing happens at some level with every filament, PLA included. On an open frame none of it is held anywhere — it goes directly into the room, for the whole length of the print.

GAP 02

Drafts reach the print

An open bed-slinger is exposed to every draft in the room. That shows up as warped corners and poor first-layer adhesion long before anyone blames the air.

GAP 03

The shop gets in

Sanding grit, wood dust, pet hair. On an open machine there is nothing between the shop and the rails, the lead screw or the bed.

GAP 04

It runs overnight, unattended

A print that runs eleven hours emits for eleven hours, in a room nobody is monitoring. That is the case an enclosure and a filter exist to answer.

06

01

Full-height front door

Magnetically latched, with a clear panel so a job can be checked without opening it. Generous reach to the plate and the control screen.

02

Cool-air intake, low

Filtered make-up air is drawn in at the bottom and carried across the chassis. On this design the intake is part of the cooling strategy, not only the filtration path.

03

120 mm exhaust port

Takes any Clearview filter or a ducting bracket on the standard pattern. Active exhaust is how heat leaves the enclosure rather than accumulating in it.

04

Interior LED lighting

Optional. Lets an operator check a print through the panel rather than opening the door mid-job.

05

External spool holders

The material bank mounts outside the enclosure, keeping the filament path short and the spools off the bench.

06

Printed brackets and grommets

Panels bolt to printed corner brackets. A rubber grommet takes power and USB through the panel instead of through a door gap.

Spools outside, path short

External holders carry the material bank on top of and beside the enclosure, so the filament run into the machine stays short and the bench stays clear.

Sized for a real bench

Both sizes are built to sit on a workbench rather than a purpose-built stand — but leave rear clearance for the exhaust path, and check the depth before you commit a table to it.

Air management

The enclosure contains it. The filter is what mitigates it.

Those are two halves of one system, and they only work together. It is also why this enclosure is not gasketed — restrict the airflow and you neuter the filtration, and on this design you would also be restricting the air that cools the machine. All three mount to the port pattern and are selectable when you configure the enclosure.

Tier 01 — Exhaust

Exhaust Filter

Vents outside

Fan housing, 4″ hose and window insert, with carbon and HEPA. Moves air outside and reduces fumes and smells. Needs exterior vent access and is slightly bulkier — and on an open-frame machine it is also the heat path.

Tier 02 — Recirculating

Recirculating Filter

No window needed

HEPA and activated charcoal in a streamlined unit. No window required, reduces fumes and smells. Honestly: under heavy high-temp use it isn't always a complete answer on odor.

Tier 03 — Commercial

Print Pro 3 by Donaldson

Commercial grade

Donaldson filtration with far deeper capacity than the other two. Absolute assurance on VOC and particulate mitigation. The answer when reduction isn't enough — occupied offices, clinics, labs, classrooms.

On PLA

Most people assume PLA is completely benign. Our customers who are physicians, engineers, or running professional environments don't make that assumption. Off-gassing happens at some level with every filament. The question is just what level of management is right for your space and your sensitivity.

Before you buy

Bambu advises against enclosing the A1. Here is our answer.

Bambu Lab does not recommend enclosing the A1, on the grounds that elevated internal temperature may shorten the life of the printer's electronics. We would rather you read that here than find it later.

Our response is a design one. Filtered cool air is drawn in low and routed across the chassis, and heat is carried out by active exhaust rather than allowed to accumulate. We have run this configuration on our own production machines since the A1 was released. We publish no chamber temperature and we offer no warranty, express or implied, on your printer or its electronics — that risk is yours to accept. Higher-temperature materials call for a hotter chamber and increase it.

If that trade isn't one you want to make, this isn't the right product for you, and we would rather say so now than after you've bought it.

For institutional buyers

The paperwork your facility is going to ask for.

Schools, labs, shared makerspaces. The A1 is a classroom favourite, which means the equipment clears the technical review and then stalls on documentation — someone in EHS or facilities needs written evidence before a machine goes into an occupied room. Two documents solve that, and you can read both before you buy anything.

Available with the enclosure

Safety Documentation Pack — written for this machine, not for a category.

Three to five documents, depending on the machine. Not generic shop boilerplate — every one is rebuilt around your specific make and model, with its real specifications, hazards, airflow numbers and procedures. Delivered as editable Word files, so you add your logo, your facility names and your sign-offs.

Fitment and options

Two sizes, one design.

Size 01 — A1

Bambu Lab A1

19.5″ W × 23.5″ D × 23.75″ H 495 × 597 × 603 mm

Minimum table top 22″ × 25″, rated to 80 lb, at 28–32″ working height.

Size 02 — A2L

Bambu Lab A2L

23″ W × 31″ D × 27″ H 584 × 787 × 686 mm

Larger in every dimension. Confirm bench depth before ordering — this one is 31″ front-to-back.

Leave rear clearance on both. These run active intake and exhaust, so the exhaust path needs a few inches behind the enclosure. An IKEA LACK is 21.65″ square: the A1 overhangs it front-to-back, and the A2L does not fit at all. Outside these two sizes, the same design is built to size.

Panel options

Base

White PVC with a clear acrylic front

A 1/4″ optically clear acrylic front panel so you can watch the print, with white PVC on the sides and top. Five-sided.

Upgrade

1/4″ commercial-grade panels

If you change one thing on the configurator, change this. Same thickness the whole way around, better fit, feel and finish — then pick the material that matches what you print.

• Full clear acrylic
• Smoked tinted acrylic
• Polycarbonate
• Amber orange

Clear acrylic is the best all-round choice. Smoked is the same panel with a quieter look. Polycarbonate trades scratch resistance for impact resistance. Amber orange screens UV.

Panel choice is the one option you can't change after the fact.

Who We've Worked With

More About the Clearview Infinity Enclosure

Our main objective was to give your printer an unobstructed view from any angle. At the same time, our enclosures offer easy access with a magnetically latched front door and a cable port to route all your connections.

We also have adapted options for our Carbon Air Scrubbing filter and vibration dampening feet. Both do as they suggest. The Carbon Air Scrubbing Filter uses a silent fan to pass air through a carbon filter to reduce fumes created from the 3D printing process. Especially if you are printing ABS, you will want to include the filter option. Our Vibration Dampening Feet use a multi material lamination that dissipates vibrations at 5 different levels. If you are printing in an area where printing noise needs to be reduced, this is an essential addition to your 3D printing setup.

We offer a black PETG color option for the brackets and fittings for your printer. With your purchase, we also offer STL access to these files so that you can print these fittings in the colors you want. ADDITIONALLY, with your purchase, we also offer the STL files of future attachments and accessories for your enclosure. If we come up with a mod, you get access to it for free!

If you've had problems with parts adhering to the print bed, warping, bad smell, noise, or dust; a printer enclosure is the right answer for you.

FAQ

What is your return Policy?

We have a 30 day return policy. Unused, undamaged panels that still have the masking fully attached are eligible for a full refund less return shipping. If panels are damaged (after shipment) or the protective mask layer has been removed, we cannot offer a refund. For best results in ensuring fitment and to ensure you like the setup of our enclosures consider at least partially assembling with the mask on. If you find out it isn't for you, this allows to get the return for a full refund.

There are some differences between your product pictures.

We update these often and as a small business it isn't realistic to do a fresh photoshoot for every iteration. In general function is always constant or better as we improve things. For the clearest indication of our current version, please rely on the renderings rather than the photos.

Bambu does not recommend enclosing the A1. Why are you offering an enclosure?

There is nothing wrong with taking Bambu's advice, and we say so plainly in the section above and in the product and safety overview. Many printer manufacturers carry a similar warning, and many owners still enclose successfully. Our engineering response is cool-air intake routed across the chassis and active exhaust to carry heat out rather than let it accumulate. We have run this configuration on our own machines since the A1 was released.

What we would say is that without an enclosure you are more likely to see warping, drafts reaching the print, and dust in the motion system — and the printer is off-gassing into an open room the whole time. Higher-temperature filaments call for a hotter chamber, which increases the thermal risk to the electronics. We make no promise about the lifespan of your printer and offer no warranty, express or implied, on it or its electronics. If you are not willing to accept that risk, enclosing this printer is not for you.
