Atomstack A20 Pro IR Fiber Laser Engraver Enclosure - Universal Fit

The Atomstack A20 Pro IR Fiber Laser Engraver Enclosure by Clearview Plastics is a made-to-fit safety and ventilation upgrade built specifically for the Atomstack A20 Pro — the 400 × 400 mm open-frame 1064 nm fiber engraver. Because it runs a 1064 nm infrared head, it needs more than a diode box: this enclosure surrounds the A20 Pro with aluminum-lined composite panels that absorb stray beams and a 1064 nm-rated viewing window, plus full fume and soot control.

Your A20 Pro drops right into the enclosure's 750 x 755 x 405 mm (29.5" x 29.75" x 16") external footprint — roughly 740 x 745 mm inside the frame, with about 400 mm (15.75") of height for the gantry, the rotary, and a tumbler. The A20 Pro's frame fits inside the IR / Fiber V3 with clearance on every side — a clean, made-to-fit match. It assembles in minutes with a screwdriver and Allen key and requires zero modification to your machine.

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 fine particulate that settles on rails, lenses, and electronics, while fumes drift straight into the room you're standing in. The IR / Fiber V3 wraps your machine in commercial-grade aluminum-lined composite 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.

Why 1064 nm needs a different enclosure

A 1064 nm fiber beam is invisible near-infrared. Your blink reflex never fires because your eye never registers a flash, and the beam reflects off metal workpieces in directions you're not looking — which is exactly why open-frame IR engraving is riskier than diode work. Critically, the amber acrylic panels used on diode enclosures block blue light (~450 nm) but do nothing at 1064 nm. This enclosure is built for IR: aluminum-lined composite panels absorb stray and reflected beams, and a 1064 nm-rated viewing window lets you watch the job while the infrared stays inside the box.

Deploys fast and works with your workflow

This enclosure was engineered around how open-frame fiber 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 15.75" (400 mm) of internal height clears the rotary and the laser head, with room for objects up to an 80 mm tumbler or ring mandrel.
• 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 beam, smoke, and soot

Open-frame 1064 nm fiber engravers are rated Class 4 — the highest laser hazard class — and marking metal releases fine particulate and fumes you don't want to breathe. The IR / Fiber V3 gives you real containment on both fronts:

• 1064 nm-rated viewing window — watch the job in real time while the invisible infrared beam is blocked.
• Aluminum-lined composite panels — absorb stray and reflected 1064 nm energy instead of passing it into the room.
• 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.

Important: even with a 1064 nm-rated window and beam-absorbing panels, always wear OD-rated 1064 nm safety glasses while the laser is in use, and never defeat your machine's interlocks. This enclosure is designed to contain 1064 nm energy and fumes, but it is not certified to ANSI standards and does not reclassify your Class 4 laser.

About Clearview Plastics

Neil Henderson here, owner and head designer at Clearview Plastics. My shop is a California-based artisan design studio, and we build every enclosure in-house in Sacramento. Our panels are professionally CNC-cut for accuracy, with parts designed specifically for each machine we support — this isn't a generic box off a marketplace. When you order through us, you work directly with me, and that relationship comes with my genuine appreciation and skilled, personal help.

Frequently asked questions

Does this enclosure block the 1064 nm laser?
It's built to contain it. The aluminum-lined composite panels absorb stray and reflected 1064 nm energy, and the viewing window is rated for 1064 nm so you can watch the job without the infrared passing into the room. That said, always wear OD-rated 1064 nm safety glasses while the laser runs — the enclosure is designed to contain IR but is not certified to ANSI standards and does not reclassify your Class 4 laser.

Can I use the amber diode panels instead?
No. Amber acrylic blocks blue diode light (~450 nm) but does not block 1064 nm infrared. IR requires opaque, absorptive panels and a 1064 nm-rated window — which is exactly what this enclosure uses. If you run a diode head, see our diode Universal V3 enclosure instead.

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 400 mm / 15.75") clears the rotary and the laser head, with enough room to engrave objects up to an 80 mm glass, tumbler, or ring mandrel.

What's included, and what do I supply?
The base kit includes the composite panels, viewing window, 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.
