• Alconox
The recommended cleaning agent for removing deposits of laurolactam and other o-
gassing stains from the printer’s optical components. It is the first cleaning agent to be used,
followed promptly by distilled water and ethanol.
• Compliant vacuum that is grounded and bonded (e.g., Class II, Division 2 vacuum)
Certified for use with materials whose fine particles present an explosive risk when in the
vicinity of potentially malfunctioning electrical equipment. Used to regularly remove loose
powder from the workspace of the Fuse 1 and Fuse Sift.
• Distilled water
The second agent used for cleaning the printer’s optical components.
• Ethanol
The last recommended denaturing agent used for cleaning the printer’s optical 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.
• Polyester cloth swabs
Disposable lint-free polyester cloth swabs with either orange or blue plastic handles for
cleaning the IR sensor and camera lens. Do not reuse a polyester swab—dispose of after
each use.

6.3 Tasks between uses
Sintering powder results in the production of o-gases and laurolactam, which collect on various
components in the print enclosure and air system. In order to preserve the accuracy and reliability
of the product, it is important to regularly check and clean several components and assemblies.
