Sensitive Components; Emergency And Exceptional Situations - formlabs Fuse 1 Manual

• Distilled water
The second agent used for cleaning the printer's optical components.
• Ethanol (laboratory-grade)
The last recommended denaturing agent used for components.
• PEC*PADs
Disposable lint-free, non-woven microfiber cloths for cleaning the printer's optical
components. Do not reuse a PEC*PAD; dispose of after each use, even when cleaning the
windows on the optical cassette with the same cleaning agent.

Sensitive components

The Fuse 1 has multiple components that are vulnerable to permanent damage if not
periodically inspected and properly maintained. Using any tools, cleaning agents, or methods
not mentioned in this manual may result in permanent damage to these components.
Follow the maintenance instructions outlined in this manual, pre-print checkpoints on the
touchscreen when starting a print, and on support.formlabs.com when servicing the following
components or any other internal component of the printer.
• IR sensor
The Fuse 1 uses an infrared (IR) sensor to monitor conditions inside the print enclosure,
and as a secondary interlock measure for the laser. Refer to section 5.4.4 Checking the
IR sensor for more information.
• Optical windows
There are two individual optical windows contained within the cassette assembly, both
of which need to be inspected after each print and cleaned regularly. They protect the
camera and upper laser window. Refer to section 6.3.1 Cleaning the optical cassette for
more information.
• Upper laser window
The upper laser window encloses the laser's aperture and galvo-driven mirrors to prevent
detrimental accumulation of laurolactam. While the upper laser window is protected by the
cassette's optical windows, it may be necessary to inspect and clean it if explicitly instructed
to do so by Formlabs or a certified service provider. Refer to section 6.5.5 Cleaning the
upper laser window for more information.

Emergency and exceptional situations

Formlabs has made every effort to provide updated safety data sheets (SDS) for every powder
product, in accordance with the latest government guidelines. Always consult the safety data
sheet (SDS) as the primary source of information to understand safety and handling of Formlabs
materials and required accessories.
3.5.1 Fire
Do not use water to extinguish an electrical fire. Dousing an electrical fire with water
increases the risk of electrocution, and may cause the fire to spread by allowing
DANGER
electricity to conduct across additional flammable surfaces.
