Minimize downtime by transferring modular build chambers and powder cartridges between Fuse 1 generation printers and the Fuse Sift, enabling a continuous workflow.

Each Fuse 1 generation printer includes one build chamber. Adding an extra chamber lets you start a new print immediately after the last job finishes. Once a print is complete, simply move the chamber to the Fuse Sift for cooling, part extraction, and material recovery.

The Form 4L Resin Mixer enhances material performance by keeping resin evenly mixed in the tank throughout printing.

A Resin Mixer is required for every print job and is designed to last for the lifetime of your printer. For added convenience, we suggest pairing each Resin Tank with its own Resin Mixer.

INTAMSYS® TPU is a highly flexible thermoplastic polyurethane (TPU) filament that delivers excellent print quality, strong elasticity, and a high strain-to-failure.

PA6/66 is a copolymer of PA6 and PA66 offering high rigidity, strength, and impact resistance, making it versatile for many engineering applications. With a low coefficient of friction, it’s also ideal for ergonomic tools and moving components.

INTAMSYS® ABS-HS is an Acrylonitrile-Butadiene-Styrene (ABS) filament engineered for FFF 3D printing. Designed for speed, it delivers a melt index of 9–24 g, enabling up to 250% higher flow rates than standard ABS. The material combines excellent print quality, strong mechanical performance, and reliable heat resistance with moderate printing temperatures and outstanding warping resistance.

Over time, tube performance will deteriorate resulting in slower fill times. Resin Pumping System tubing must be changed out every 6 months or when changing to a different resin type. This kit includes both the internal tubing for the Resin Pump as well the Transfer Tube to connect the Resin Pump to the 5 L Resin Container.

Replacement Tubing for the Resin Pumping System. Resin Pumping System tubing must be replaced every 6 months to maintain resin pump performance or any time the is changed to a different resin type. This kit includes the internal pump tubing and transfer tubing needed for the replacement.

Form Wash automatically cleans printed parts thoroughly and efficiently with IPA or alternative solvents. Keep parts directly on the Build Platform as you transition them from the printer to Form Wash, or remove parts and place them in the wash basket. Parts are precisely and thoroughly agitated in solvent with an impeller, getting every nook and cranny perfectly clean, automatically for the appropriate time. When washing completes, the Form Wash automatically raises parts out of the IPA so they can air dry.

The Form 4 Build Platform features a durable aluminum surface. Keeping a spare platform on hand helps you maintain nonstop printing—swap quickly when changing resins or starting a new job while removing finished parts. For the fastest, easiest workflow, we recommend the Build Platform Flex with Quick Release Technology.

The portable SLS Vacuum is NFPA-652 compliant and safe for use with all Formlabs SLS powders. It connects directly to the Fuse Sift hose for clearing build chambers, removing debris, and keeping your SLS workspace clean. Note: the Powder-Safe SLS Vacuum operates independently and cannot be controlled or auto-triggered from the Fuse Sift interface.

Make your SLS Workflow workspace-friendly with the Fuse Sift Glovebox Bundle, a comprehensive solution that combines the Fuse Sift Glovebox Panel and Fuse Parts Carrier to streamline your part extraction workflow and minimize powder exposure.

The Fuse Blast Polishing System is a drop-in upgrade to the Fuse Blast that allows users to add a smooth, semi-gloss, scuff-resistant, and dye-ready surface finish to their SLS printed parts. With the Polishing System, users can create parts for consumer-facing, end-use applications with improved feel and appearance. 

This single-step add-on to the Fuse Blast both cleans and polishes your parts straight from the Fuse Sift without the need for another Blast.

Step into the future of ceramic engineering with the world’s most accessible ceramic 3D printing ecosystem. Harness 3D printing to produce advanced ceramic components without costly tooling—cutting lead times and expenses while unlocking greater design freedom.

Alumina 4N is a Form X material built for expert users, offering a high-density, high-purity technical ceramic. It delivers exceptional performance in extreme environments—thermally resistant, mechanically strong, chemically inert, hard, and abrasion-resistant.

Alumina 4N Resin has a shelf life of 3 months at room temperature, which can be extended by up to 12 additional months when refrigerated (-10–4 °C). Refrigeration is strongly recommended.

Please read the Alumina 4N Quick Start Guide before proceeding. If this is your first time using a Formlabs 3D printer, we strongly recommend using a general purpose resin, such as Clear Resin, before printing with Alumina 4N resin.
