Every enclosed desktop laser we have looked at leaks somewhere: around the lid, at the exhaust adapter, through the underside, or straight out of the purifier housing. The reason is the same on all of them. A fan inside the machine pushes air toward the exhaust, and a pushed chamber sits at positive pressure. Positive pressure finds every seam.
Every F-series Ultra runs with the hood raised for rotary and conveyor work, and xTool's own safety guide says diffused laser beams may leak out from the openings when the protective enclosure is lifted. The rear fan pushes metal particulate out a 3 inch port; one reviewer found half a garage under a layer of powder after a slate job. The US units are Class 4 as sold and require a designated laser safety officer.

First, the plain fix: a stronger exhaust with the fan at the far end of the duct, so the machine runs under vacuum. If you can do that, do it. Not everyone can. A classroom with no window, an apartment, a shared shop, a machine that sits next to a bedroom wall.
The Supplemental Enclosure is a rigid outer enclosure cut to fit the xTool F1 Ultra / F2 Ultra with room for the lid to open inside it. The machine sits inside. Its exhaust connects directly to a pass-through duct in the enclosure wall, so your hose run to a window or purifier is unchanged. Whatever escapes the machine's seams is now inside a second box instead of the room, and because the machine pulls its intake air from inside that box, leaked smoke gets drawn back through the machine and out the exhaust on the next pass. A second barrier and a return loop. Nothing else to set up.
It is not a tent. CNC-routed acrylic panels, aluminum hardware, a full-width front door, and the same bolt-together construction as our 3D printer and laser enclosures. Brackets and hardware are included in every order. The machine's own enclosure remains the laser safety barrier; this enclosure uses standard acrylic and is not a laser-rated product.


Standard acrylic. It does not contain the beam, and the hood remains the laser safety barrier: xTool's Class 4 rules and eyewear apply whenever the hood is raised. Not compatible with the Conveyor. Machine option: F1 Ultra body, or F2 Ultra / F2 Ultra UV body.
Schools, libraries, and makerspaces whose laser policy already requires supervised, restricted access and that would rather add containment than add rules. Home shops with a bedroom, a nursery, or a neighbor on the other side of the wall. Anyone who bought a purifier, ran it, and still smells the job the next morning.
We are building this around real units. Use the notify-me button above and we will tell you when it is ready. If you own a different enclosed laser, tell us which one when you reach out. If enough of you ask for the same machine, we will build that one next.
