Directed Energy Deposition (DED) Metal 3D Printer Enclosure — Fiber Laser Safety & Fume Containment

The Directed Energy Deposition (DED) Metal 3D Printer Enclosure by Clearview Plastics is a heavy-duty, industrial-grade containment enclosure for laser DED metal additive systems. DED builds and repairs metal parts by using a focused fiber laser to melt metal powder or wire as it's deposited — a Class 4, 1064 nm process that throws intense light, metal fume, and spatter. Built from 1/4" aluminum composite panels with an OD7+ 1064 nm laser-safety viewing window, this enclosure contains the beam, the glare, and the fume so you can run metal deposition in a shared or indoor space.

Based on the largest size of our fiber laser marker enclosure, it gives you a full XL+ working envelope — 21.5" W × 29.5" D × 38.25" H — with room for a DED head, feedstock, and workpiece. It's a "set-over" enclosure that assembles with a screwdriver and hex wrench, or ships delivered assembled, and configures with the doors, sealing, interlock, and filtration a metal-AM shop needs.

Built for laser DED metal additive

Directed Energy Deposition (also called laser metal deposition, LMD, or laser cladding) melts metal powder or wire feedstock with a focused laser to build up, coat, or repair metal parts. It's a fast, powerful process — and an open DED head is one of the more hazardous things you can run on a bench: an invisible 1064 nm beam, blinding process light, hot spatter, and a plume of fine metal fume. This enclosure is sized and shielded to wrap a desktop / benchtop DED cell and bring all of that under control.

Running a specific DED head or a higher-power system? Send us your machine, laser power, and footprint and we'll confirm the fit and the right window/panel spec before you buy.

Contain the beam and the glare

• OD7+ viewing window (1064 nm) — an 11 × 11" laser-safety window (800–1100 nm, ~30% transmittance) so you can watch the melt pool without the infrared reaching your eyes.
• Aluminum composite panels — opaque, rigid, and beam-stopping; not clear acrylic.
• Door gasketing — seals the door perimeter to keep metal fume in and block stray light leakage around the edges.

Contain the metal fume and spatter

DED generates fine metal fume and particulate that you do not want in your breathing zone. Capture it at the source:

• 4" exhaust adapter — connects a flexible 4" hose on the rear panel to vent outdoors or to a filter.
• Fan & venting options — add a 95 CFM or 200 CFM fan, or our window exhaust kit, for the extraction your process needs.
• Donaldson AD350 filter — step up to the heavy-duty Donaldson AD350 filtration unit, purpose-built for metalworking and laser fume, when venting outside isn't an option.
• Flow-control vents — slide-open vents tune airflow across the work zone for better capture.

Configure your enclosure

• Size — this listing is the XL+ (21.5 × 29.5 × 38.25"); contact us if your DED cell needs a custom envelope.
• HD hardware upgrade — metal hinges, heavier binding-screw hardware, and metal door pulls.
• LightBurn hood camera — hood-mounted USB camera for monitoring the build without opening the door.
• Additional side doors — with two side doors the enclosure doubles as a pass-through for long or oversized workpieces.
• Additional seam sealing — extra sealing for tighter fume and light containment.
• Magnetic door interlock switch — a 2-wire interlock lead to tie into your machine's safety circuit.
• Delivered assembled — have it shipped built and ready to use instead of flat-packed.

Important safety information

This enclosure is designed for laser-light and fume containment. It is not a fire-rated or thermal chamber. DED is a high-temperature process involving molten metal, and some feedstocks — especially reactive metal powders such as titanium and aluminum — carry fire and explosion hazards. You are responsible for thermal management, fire safety, inert-gas / atmosphere requirements, and safe handling of reactive materials per your machine manufacturer and local codes. The enclosure contains stray light and fume but does not reclassify your Class 4 laser and is not certified to ANSI standards. Always wear OD-rated 1064 nm safety glasses and never defeat your machine's interlocks. Contact us to review your power level and setup before ordering.

Why choose the Clearview DED enclosure

• Genuine laser-safety window — OD7+ for 1064 nm, not a clear hobby panel.
• Industrial-grade build — 1/4" aluminum composite panels with door gasketing, in our largest XL+ size.
• Real metal-fume control — 4" exhaust plus Donaldson AD350 filtration options.
• Configurable for a real cell — side-door pass-through, interlock, seam sealing, and assembled delivery.
• US-made by a small business — CNC-cut in Sacramento with genuine, hands-on support.

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

What is DED and why enclose it?
Directed Energy Deposition melts metal powder or wire with a focused laser to build or repair metal parts. The process produces an invisible 1064 nm beam, intense process light, hot spatter, and fine metal fume — this enclosure contains the light and captures the fume so you can run it safely indoors.

Does this block the 1064 nm laser?
It's built to contain it: aluminum composite panels stop stray/reflected beams and the OD7+ viewing window is rated for 1064 nm so you can watch the melt pool. Always still wear OD-rated 1064 nm safety glasses — the enclosure contains the beam but is not certified to ANSI standards and does not reclassify your Class 4 laser.

What about heat, fire, and reactive metals?
This is a light-and-fume containment enclosure, not a fire-rated or inert-atmosphere chamber. High heat, molten metal, and reactive powders (titanium, aluminum) carry fire/explosion risk that this enclosure does not mitigate. Follow your machine manufacturer's thermal, atmosphere, and material-handling requirements and local codes. Contact us to review your setup.

What are the exhaust and filtration options?
A 4" exhaust adapter is included. Add a 95 CFM or 200 CFM fan or our window exhaust kit, or step up to a heavy-duty Donaldson AD350 filtration unit built for metal and laser fume.

What size is it, and can I get a custom envelope?
This is our largest XL+ size (21.5 × 29.5 × 38.25"). If your DED cell needs a different envelope, contact us — we build to order.

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.
