1 Preface
Congratulations on purchasing the Fuse Sift. On behalf of the Formlabs team, we thank you
for your purchase. The Fuse Sift is the powder recovery station for the Fuse 1, a Selective
Laser Sintering (SLS) 3D printer.
When a print is finished, the resulting parts are buried in loose, unsintered powder and need
to be extracted. The workspace provided by the Fuse Sift allows users to extract parts from
a build chamber, reclaim unsintered powder, store both reclaimed and fresh powder, as well
as combining powder streams for printing. An air handling system helps reduce plumes from
free floating powder, and integrates a vacuum for easy cleanup.
This manual explains how to set up, use, and properly maintain the Fuse Sift, as well as
provides design guidance for optimizing print results.
The manual is intended for anyone who is installing, operating, maintaining, or otherwise
interacting with the Fuse Sift. Supervise young or inexperienced users to ensure enjoyable

additively fabricated parts.
You shall independently verify the suitability of additive manufacturing, Selective
Laser Sintering (SLS), the Fuse Sift, and any specific designs or materials employed
for the application and intended purpose before use. In no event shall Formlabs be
liable for any loss, death, or bodily injury that you suer, or that you cause to any third
party, in connection with your use of Formlabs products. To the fullest extent legally
permitted Formlabs EXPRESSLY DISCLAIMS ANY IMPLIED OR EXPLICIT WARRANTY
OF FITNESS for a particular usage, the particular nature and circumstances of said
usage being unforeseen and unforeseeable to Formlabs.
Formlabs is not a manufacturer of medical devices. Formlabs provides tools and
materials that may be used in many applications, but makes no claims as to the safety
or eectiveness of any specific devices made using Formlabs products. Certain
Formlabs products, such as those commonly known in the industry as “biocompatible”
materials, have been engineered to comply with relevant industry standards. The
specific standards and most relevant technical specifications may be identified
within the technical data sheets and have been tested according to relevant testing
protocols for those standards and specifications. Biocompatible materials are a
speciality product, developed for use by medical professionals, and should be used in
accordance with the instructions for use.

3.1 Component and subsystem safety
3.1.1 General
The Fuse Sift requires a 230 VAC (50 Hz), 7.5 A power supply (EU) or 120 VAC (60 Hz),
15 A power supply (US) for nominal operation. Unless explicitly instructed by Formlabs
Support or a certified service provider, do not disassemble or tamper with the
product beyond what is explicitly outlined for typical maintenance. Tampering with,
or disassembling the Fuse Sift prior to disconnecting the power cable and waiting
approximately ten minutes can subject users to potentially fatal electrical hazards.
The Fuse 1’s print enclosure is designed to operate at up to 200 °C (392 °F) and
incorporates high-intensity heaters. Do not open the print enclosure or any other
access doors on the printer during or immediately after a print. Do not handle parts
from a build chamber without allowing the entire print enclosure to cool for several
hours, or until the build chamber temperature has reached ≤ 100 ºC (212 °F). Use
the provided thermal-insulating silicone gloves when handling a hot build chamber.
Failure to follow these procedures will result in serious injuries, including burning and/
or scalding of skin.
Due to its size and weight, do not move or reposition the Fuse Sift alone. If the machine
needs to be moved, at least two individuals should unlock the casters and push the
entire unit by the metal frame. Avoid using the workspace hood as a push-o point.
Do not lift or reposition the Fuse Sift:
• By grabbing or pulling on the workspace hood, workspace lip, build chamber
enclosure, build chamber latch, or power cable.
• By pushing on any side of the unit while stationary.
• When the build chamber that is still hot inside is loaded in the build chamber
enclosure.
The Fuse Sift requires an operating environment that is low in ambient humidity and
static electricity. Refer to section 4.1 Location and environs for the recommended
operating environs. When performing maintenance or testing with the exterior
paneling of the machine removed, ground equipment to the grounding stud marked
