Setup & Ease of Use

Plug and print

Easy workflow empowers anyone at your company to use the system independently after minimal training. Formlabs offers contact-free delivery and online or in-person advanced training for the entire team to make onboarding even easier.

Maintenance

Minimal

Formlabs SLA systems require minimal maintenance. In the rare case something does go wrong, the Light Processing Unit, rollers, and optical window are replaceable in-house to prevent the need for replacement printer shipments and maximize your uptime. Improved failure detection and handling means you can experiment with confidence.

Post-Processing

Form Wash & Form Cure Ecosystem
Form Wash and Form Cure, Form Wash L and Form Cure L

Our automated washing and curing solutions streamline the SLA post-processing workflow to consistently deliver high-quality results with less time and effort.

SUPPORTS

Light-touch supports

Our "light-touch supports" break off with ease, leaving behind minimal support marks that can be easily removed with light sanding.

CLEANING

Wash parts in a solvent

Cleaning printed parts in a wash solvent removes any uncured resin from the part, leaving you with a smooth surface finish. Automate washing with the Form Wash and Form Wash L.

FINISHING

Post-curing (optional)

When an SLA part finishes printing, it remains on the build platform in a “green state.” Through exposure to a combination of light and heat, post-curing unlocks this last mile of material properties. Post-curing is required for certain materials and for biocompatible parts. Automate curing with the Form Cure and Form Cure L.

MATERIAL LIBRARY

3 varieties of nylon, more coming soon

The Fuse 1 currently prints with Nylon 12, Nylon 12 GF and Nylon 11. Nylon 12 is a general purpose, versatile material with high detail and great dimensional accuracy. Nylon 11 is a ductile, strong, flexible material for when durability and performance are key. Nylon 12 GF is a glass-filled material with enhanced stiffness and thermal stability for demanding industrial environments.

THROUGHPUT

High

The Fuse 1 is designed for nonstop throughput. It comes with a removable build chamber, allowing you to start new prints right after the previous print has finished to minimize downtime. Cooldown time takes only about half the print time for large builds, an industry-leading value that allows you to get to finished parts quickly.

The Fuse 1 allows you to pack parts tightly to optimize each build for the highest productivity.

Setup & Ease of Use

SLS made manageable

From print setup to powder recovery, our hardware and software are designed to maximize your efficiency, with an intuitive interface to walk you through all steps of printing and maintenance. Anyone at your company can use the system independently after a quick online or in-person training.

Maintenance

Efficient

The Fuse 1 is designed for minimal upkeep. The system offers proactive maintenance alerts and a full-color touchscreen interface guides you through every step of printing and maintenance.

Fuse Sift
Fuse Sift

The Fuse Sift is a safe, efficient powder recovery system for the Fuse 1. This all-in-one station combines part extraction, powder recovery, storage, and mixing in a single free-standing device.

SUPPORTS

No supports needed

SLS parts are supported by powder as they print, so no supports are needed, reducing post-processing labor.

CLEANING

Clean excess powder

Extract and clean your parts from the build chamber and recover unused powder to be recycled in future prints. Use Fuse Sift as an all-in-one station.

FINISHING

Media blasting (optional)

Formlabs recommends the use of a media blasting cabinet, which uses compressed air and an abrasive media like silicon carbide to eliminate graininess and improve surface finish on SLS parts.

Space

ENVIRONMENT

Workshop

The Fuse 1 is best suited for a workshop or machine shop setting, though it can be used in an office environment. If you have a large open office environment with consistent housekeeping practices, it should be fine to install the Fuse 1 and Fuse Sift there. The Fuse Sift should be kept 10+ meters (32 ft 10 in+) away from people’s desks.
