Term Meaning
Alconox A general purpose lab cleaning agent that is recommended for cleaning
the printer’s optical components. It is the first cleaning agent to be used,
followed promptly by ethanol and distilled water, respectfully.
BirchBark A type of print defect that occurs in SLS printing when the temperatures
of a group of layers dier from each other, causing some layers to shrink
or curl inconsistently.
Build chamber An interchangeable component of the Fuse 1 that contains the print bed
(representing the Z-axis of 30.0 cm/11.8 in), heaters and temperature
sensors, and encapsulates the sintered parts and loose powder from a
print. The accompanying plug allows the Fuse 1 and Fuse Sift to monitor
the build chamber, and dierentiate one build chamber from another.
Build volume The total cubic dimensions in which 3D models can be printed. The Fuse
1 has a build volume of 16.5 × 16.5 × 30.0 cm (6.5 × 6.5 × 11.8 in).
Cake The final product of a print, containing both loose unsintered SLS
powder and the printed parts.
Computer vision (CV) A system incorporating a camera and artificial intelligence engine to
monitor prints for potential issues, and abort prints if a significant issue
is detected.
Distilled water Water that is free of impurities, and is the second agent used for wiping
o residual alconox from the previous cleaning step.
Ethanol A simple alcohol that is the recommended denaturing agent for
removing deposits of laurolactam and other o-gassing stains from the
printer’s optics.
Flippers Two paddles, one on the left and right side of the powder handling
system, that move powder into position for the recoater roller to pick-up
and deposit onto the print bed.
Galvanometer (galvo) A high-speed precision motor that positions a mirror used for reflecting
the laser spot. The Fuse 1 uses two galvos to position the laser spot
along the X and Y-axes of the print area.
Hopper The fixed container on the side of the Fuse 1 that holds powder in a
tapered basin for printing.
Interlock A safety mechanism that automatically shuts o the laser if the print
enclosure door is open, or if the IR sensor is misaligned.
Infrared (IR) Electromagnetic radiation that extends from the nominal edge of the
visible spectrum at 700 nanometers (nm) to 1 millimeter (mm).
IR sensor An electronic device that monitors the temperature in the print enclosure
by measuring infrared radiation.
Laser Short for “Light Amplification” via “Stimulated Emission of Radiation.” The
laser is the source of sintering energy in the Fuse 1 with a wavelength
of 1065 nm, and a maximum output of 10 W. The Fuse 1 is a Class 1
laser product.
Laurolactam An organic compound used as a monomer to produce nylon. It is also a
byproduct of SLS nylon printing.
