Extended Laser Engraver Enclosure Kit V3

Extended-format diode lasers · 800 × 400 mm class

A set-over panel kit built for the long bed

A diode laser makes smoke the second it fires. On a long-bed machine you are dragging that plume across 800 mm of travel with nothing over the top of it — fine soot settling on the rails, the lens, and the control board, and the rest of it going into the room at bench height. Diode lasers run at 445–450 nm and are rated Class 4, so the blue flash off every pass sits in your field of view for the length of the job.

The Extended Laser Engraver Enclosure Kit V3 drops straight over the machine and gives it a controlled working envelope: 1170 × 710 × 405 mm outside, roughly 1160 × 700 mm of floor and 399 mm (15.7") of height inside. Commercial-grade 1/4" (6 mm) acrylic panels on a rigid 2020 aluminium extrusion frame, with magnetically latched front and top doors. No fabrication, no permanent modification to the machine, and it lifts back off for service or transport.

It is not airtight, and it is not built to be. The enclosure's job is to contain and concentrate what the laser puts out so your extraction can pull it away. That system needs airflow to work, which is why the vents are adjustable and the exhaust ports are sized for a real 4" hose.

Fits extended and long-rail diode engravers

• xTool D1 Pro (with extension) — 432 × 936 mm travel

One universal size built around the long-bed footprint. If your model is not listed, send us your machine's frame dimensions and we will confirm the fit before you order.

What's on it

• Dual access doors — magnetically latched front and top, so you can load long stock from the front and reach in over the bed from the top
• Two 4" exhaust ports on the rear panel — run whichever side suits your bench and clamp a 4" hose to it
• Adjustable airflow vents — set intake volume and direction so air crosses the bed toward the exhaust
• Three wire grommet ports — power, air-assist tubing, and USB pass through with the doors shut
• Hood camera mount — an optional USB camera mounts in the lid for LightBurn alignment and tracing
• 399 mm (15.7") of internal height — clears a rotary and a fully articulated laser head, with room for an 80 mm tumbler or glass

Air management

Two parts doing two jobs: the enclosure contains and concentrates the plume at the source, and extraction takes it away. Vent it outside with the window exhaust kit (inline fan, window insert, and 16 feet of hose), a 95 CFM fan with bracket for lighter work, or the 200 CFM compact for more air across the bed. Where venting outside is not possible, a BOFA PrintPRO 3 unit gives you professional fume filtration for indoor operation. You supply a 4" dryer hose.

Optional amber laser-filtering panels

Spectrometer transmittance measured on the same 6 mm amber stock we cut: 0.158% at 400 nm, 0.115% at 450 nm, 0.013% at 500 nm, and 0.060% at 520 nm. At 450 nm — where a diode laser operates — that takes the harsh blue flash out of your work area so you can watch a job run without squinting past it.

The amber panels reduce glare. They are not a laser-safety window. They do not reclassify your Class 4 laser and they are not a certified laser-viewing window. Wear OD-rated safety glasses for your wavelength — OD5+ for a 450 nm diode — any time the laser is running.

What ships

• CNC-cut 1/4" (6 mm) acrylic panels — clear, or amber laser-filtering
• Rust-resistant hardware and the 2020 aluminium extrusion frame
• Print files for every bracket — add our pre-printed parts if you would rather build than wait
• Every printed part stays in the file repository you get after ordering, so you can reprint anything that breaks or gets revised

Compliance, straight

This enclosure is built for fume containment and glare reduction. It does not reduce a Class 4 laser to Class 1, and it is not a certified ANSI Z136.1 enclosure. If your facility's safety policy requires one, contact us directly and we will talk through what you actually need.

CNC-cut in Sacramento, California. 30-day returns on unused, undamaged panels with the masking still attached — test-fit with the mask on and you stay eligible.

The Extended Laser Engraver Enclosure Kit V3 by Clearview Plastics is a made-to-fit safety and ventilation upgrade for extended-format (long-bed) diode laser engravers — the ~800 × 400 mm-class machines with a stretched Y-axis that won't fit a standard square enclosure. If you run an xTool D1 Pro, Neje 3/4 Max, Algolaser Alpha, iKier K1, or AtomStack X40 Max, this is the enclosure built to protect it, contain its smoke, and fit the way you actually work.

Designed and CNC-cut in the USA, this "set-over" tabletop enclosure drops right over your engraver and holds it in a sealed working envelope. It has a 1170 x 710 x 405 mm (46" x 28" x 16") external footprint and is framed in rigid 2020 aluminum extrusion, leaving an internal working area of roughly 1160 x 700 mm with about 399 mm (15.7") of height — room for the long gantry travel, the rotary, and a tumbler. Every machine on our compatibility list fits this one universal size. It assembles in minutes with a screwdriver and Allen key, requires zero modification to your machine, and comes ready for the camera, lighting, and exhaust accessories that turn a bare frame into a professional workstation.

Built for the long bed — extended-format diode lasers

Extended and long-rail diode engravers are the machines most enclosures simply can't handle — their stretched Y-axis runs right past the walls of a standard box. The Extended V3 is sized and vented for exactly these machines, including:

• xTool D1 Pro (with extension) — 432 × 936 mm travel
• Neje 3 / 4 Max — 750 mm wide with Y-axis extension
• Algolaser Alpha (Extended) — 400 × 850 mm
• iKier K1 series (with extension) — 750 × 410 mm
• AtomStack X40 Max — 800 × 400 mm
• Most extended-format diode engravers with an approximate 800 × 400 mm work area

Every machine on this list fits the Extended V3 — one universal size built around the long-bed footprint, and the machine-specific versions are the exact same enclosure. Not sure whether your model qualifies? Send us your frame dimensions and we'll confirm the fit before you buy — no guesswork.

Protect your engraver and your shop

Running a laser open on a bench is the fastest way to foul your shop and shorten your machine's life. Every pass lays down a fine soot that settles on rails, lenses, and electronics, while smoke and fumes drift straight into the room you're standing in. The Extended V3 wraps your machine in commercial-grade 1/4" (6 mm) panels that keep debris off your engraver, contain the plume at the source, and give you a clean, controlled environment every time you fire the beam. It's the difference between a machine that looks new in three years and one that doesn't.

Deploys fast and works with your workflow

This enclosure was engineered around how extended-bed diode owners actually run jobs — not just to be a box:

• Quick to deploy — no part swaps or permanent modifications. A screwdriver and Allen key are all you need, and the set-over design means you can lift it off for maintenance or transport.
• LightBurn-compatible hood camera — an optional USB camera mounts to the lid for accurate part alignment and LightBurn tracing without opening the enclosure.
• Rotary-ready — about 15.7" (399 mm) of internal height clears the rotary and an articulated laser head, with room for objects up to an 80 mm tumbler or glass.
• Adjustable airflow vents — offer control over airflow volume and direction for cleaner, more efficient extraction.
• 3 wire grommet ports — feed in wires, air-assist tubing, and anything else that needs to pass into the enclosure.
• Dual access doors — magnetically latched front and top doors make loading and adjustments easy.

Contain the smoke, soot, and glare

Diode lasers operate around 445–450 nm and are rated Class 4 — the highest laser hazard class. Cutting and engraving wood, acrylic, leather, painted, stained, or sealed materials releases smoke and fine particulate you don't want to breathe. The Extended V3 gives you real containment:

• Two 4" exhaust ports — select which side vents to best suit your workspace, connect a flexible 4" hose, and route smoke and fumes out a window or to a filter. Pair it with a 95 CFM or 200 CFM fan, our window exhaust kit, or PrintPRO 3 filtration for the level of extraction you need.
• Adjustable airflow vents — fine-tune airflow volume and direction for efficient source capture.
• BOFA PrintPRO 3 compatible — integrate a professional fume-filtration system for indoor operation without external venting.
• Optional amber laser-filtering panels — spectrometer-tested to block up to 99.8% of light transmission at 450 nm (OD3+ filtering up to 520 nm), dramatically cutting the harsh blue flash for a far more comfortable work area.

Important: the laser-filtering panels reduce indirect glare but are not a certified laser-safety window and do not reclassify your Class 4 laser. Always wear OD-rated safety glasses for your wavelength (e.g. OD5+ for 450 nm diodes) while the laser is in use. Need an enclosure that meets ANSI guidelines? Contact us directly.

Frequently asked questions

Will my extended / long-bed laser fit?
The enclosure has a 1170 mm W x 710 mm D x 405 mm H external footprint, leaving roughly 1160 x 700 mm and about 399 mm of height inside the frame — sized for extended-format machines with an approximate 800 × 400 mm work area. Every machine on our compatibility list fits, including the xTool D1 Pro, Neje 3/4 Max, Algolaser Alpha, iKier K1, and AtomStack X40 Max. If your model isn't listed, send us your machine's frame dimensions and we'll confirm fit before you order.

Do the laser-filtering panels mean I don't need safety glasses?
No. The amber panels filter light at the wavelength diode lasers operate at and greatly reduce indirect glare, but they are not a certified laser-viewing window. Always wear appropriate OD-rated safety glasses (e.g. OD5+ for 450 nm) whenever the laser is running.

Does this enclosure comply with ANSI Z136.1?
No. This enclosure is designed for fume containment and glare reduction, not to reduce a Class 4 laser to Class 1. Follow all Class 4 laser safety protocols. If you need an enclosure that meets ANSI guidelines, contact us directly.

Does it have an exhaust port for smoke and fumes?
Yes. The enclosure includes a 4" exhaust port to connect a flexible 4" hose and vent outside. From there, add the fan setup that fits your workload: a 95 CFM exhaust fan (includes the mounting bracket) for light-duty use, a 200 CFM compact fan for added air circulation, or our window exhaust kit — an inline fan, window insert, and 16 feet of hose. If venting outside isn't possible, add a BOFA PrintPRO 3 filtration unit to clean the air indoors.

Is there room for a rotary?
Yes. The internal height (about 399 mm / 15.7") clears the rotary and a fully articulated laser head, with enough room to engrave objects up to an 80 mm glass or tumbler.

What's included, and what do I supply?
The base kit includes acrylic panels and hardware; you print the brackets from the included files. Add our pre-printed parts for a complete kit. In all cases you supply a 4" dryer hose, and for heavy use we recommend adding an inline exhaust fan.

Do you ship internationally?
Yes. Shipping is calculated at checkout via USPS/UPS/FedEx (HS code 8538.10). Express services often cover import fees, but additional VAT, tariffs, or fees may apply depending on your country.

What is your return policy?
We offer a 30-day return policy. Unused, undamaged panels with the masking fully attached are eligible for a full refund less return shipping. If panels are damaged after shipment or the protective mask has been removed, we can't offer a refund. To check fitment, consider partially assembling with the mask still on — if it isn't for you, you're still eligible for a full refund.

Why do the product photos vary slightly?
We update and improve our enclosures often, and as a small business a fresh photoshoot for every iteration isn't realistic. Function is always constant or improved. For the clearest picture of the current version, rely on the renderings rather than the photos.
