Formlabs Fuse Sift Glovebox Bundle – Enclosed Powder Recovery System

The Formlabs Fuse Sift Glovebox Bundle is a powder containment accessory kit for the Fuse Sift post-processing station, designed to keep SLS powder off your hands and out of your workspace during part extraction. The bundle combines the Fuse Sift Glovebox Panel — a hood-mounted enclosure with integrated rubber gloves — and the Fuse Parts Carrier, a lidded transport container for moving depowdered parts directly to the Fuse Blast or any downstream finishing station. Compatible with the Fuse 1 and Fuse 1+ 30W.

What the Bundle Solves

SLS powder is fine, light, and pervasive. Without containment, every part extraction session leaves a film of nylon dust on tools, surfaces, and skin. The Glovebox Panel mounts directly onto the Fuse Sift hood and fully encloses the work surface, creating a sealed chamber where loose powder stays — not on your bench or in the air. The two integrated glove ports let you work naturally: separate parts from unsintered powder, brush surfaces, and handle prints without contact.

The vent suppression is equally important. When Glovebox Mode is activated through the Fuse Sift touchscreen, the built-in vent fan is suspended during part recovery. Without this setting, the vent creates powder plumes inside the chamber that obscure parts and complicate the extraction process. Mode activation takes three taps: Settings → System → Glovebox Mode → Enable.

Glovebox Panel — Design and Attachment

The Glovebox Panel is a rigid panel with two oval glove ports, clamp hardware, and ventilation mesh on both sides. It slides onto the front edge of the Fuse Sift hood and locks with screw clamps — no tools required for routine removal. A foam gasket adheres to the front lip of the Fuse Sift work surface to seal the gap between the panel and the machine body, preventing powder from escaping at the seam.

The image below shows the open Fuse Sift before glovebox installation, with the clean, accessible work surface and integrated accessory tray visible.

Before mounting the panel, wipe the front lip of the work surface clean. The image below shows the gasket being peeled from its adhesive backing and applied flush to the front lip — it must cover the full width of the lip with no gaps.

Once the gasket is seated, orient the Glovebox Panel with gloves facing down and clamps facing away. Slide it onto the hood edge until the clamps engage, then tighten finger-tight. The image below shows the panel from inside the open hood, with red arrows indicating the clamp screw locations on both sides.

After closing the hood to check the fit and adjusting for minimal gaps, reopen the hood and apply the final torque to the clamp screws. The arrows in the image below point upward toward the screws to indicate the tightening direction.

With the hood closed and the panel secured, the Fuse Sift presents two oval glove ports at the front. The fully installed configuration is shown below — the Formlabs logo is visible through the transparent panel section, and the ventilation mesh flanks both glove openings.

Activating Glovebox Mode via Touchscreen

Firmware must be updated before first use. Once updated, navigate to Settings › System › Glovebox Mode on the Fuse Sift touchscreen and tap Enable. This suppresses vent fan operation during part recovery, preventing the powder plumes that make extraction difficult. The screenshot below shows the System menu with the Glovebox Mode entry.

Working Inside the Glovebox

With the build chamber inserted and cake ejected, insert both hands through the glove ports and work normally. Use the sift function to let loose powder fall through the grate, then separate parts manually, with brushes, or with other tools. The image below shows a technician with one arm through a glove port and a brush in the other hand, actively depowdering parts.

Fuse Parts Carrier — Dust-Free Part Transfer

Once parts are separated from unsintered powder inside the glovebox, they need to travel to the Fuse Blast without recontaminating the workspace. The Parts Carrier slots into the Fuse Sift's build chamber enclosure: remove its lid, load your parts, replace the lid, then lift it out and carry it directly to the next station. The transparent body lets you confirm contents without opening.

Glove Maintenance and Replacement

After each session, brush or vacuum excess powder off the gloves before opening the hood — this prevents loose powder from falling onto the work surface or floor. The gloves are replaceable: a hose clamp secures each glove around its port, and a small flathead screwdriver is all that is needed to swap a damaged glove. A technical drawing of the Glovebox Panel with both gloves and hose clamps is shown below.

Finally, before cleaning the Fuse Sift work surface lip for gasket installation, use a clean cloth to wipe away any residual powder from the front lip. The image below shows this preparatory cleaning step.

Tech Tip: When opening the Fuse Sift hood between sessions, hang the gloves from the hook on the inner face of the Glovebox Panel or pull them inside-out before lifting the hood. Either method prevents loose powder trapped in the gloves from spilling onto the work surface and undoing the containment the glovebox is designed to provide.
