Meaning
Build chamber
An interchangeable component of the Fuse 1 that contains the print bed,
heaters, and temperature sensors, and encapsulates the sintered parts
and loose powder from a print. The accompanying plug allows the Fuse
Sift and the Fuse 1 to monitor the build chamber, and differentiate one
build chamber from another.
Build chamber enclosure
The area in the Fuse Sift for housing the build chamber with prints ready
to be ejected.
Build chamber port cover
A removable plate that prevents airflow through the bed port in the
workspace and keeps powder, printed parts, and tools from falling into
the build chamber enclosure.
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 part.
Cartridge drawer
The cartridge drawer holds a powder cartridge to be filled with powder
from the Fuse Sift. Sensors in the cartridge drawer ensure that the
powder cartridge is filled to the proper level.
Cartridge valve
The primary opening for filling and depositing powder. The cartridge
valve is opened and closed via the valve knife.
Hood
A transparent covering that prevents powder and debris from leaving
the Fuse Sift’s workspace.
Hopper
A fixed container that holds powder in a tapered basin for dispensing
into a powder cartridge. The Fuse Sift has two hoppers: one for fresh,
unused powder, and one for unsintered powder recovered from
previous prints.
Laurolactam
An organic compound used as a monomer to produce nylon. It is also a
byproduct of SLS nylon printing.
Micron (µm)
An SI derived unit of length equalling 1×10
−6
meter, or one millionth of a
meter (or one thousandth of a millimeter, 0.001 mm, or about 0.000039
inch).
Mixer
The mixer spins a filled powder cartridge to ensure a homogeneous
distribution of fresh and used powder.
Nylon
An industrial thermoplastic that bends before returning to its original
form without fracturing, making it suitable for structural, load bearing, or
mechanical parts.
Personal protective
equipment (PPE)
Garments or articles of clothing designed to protect individuals
from physical, electrical, heat, chemicals, biohazards, and airborne
particulate matter.
Plume
A localized emission of pulverized material.
Powder cartridge
The container in which SLS powder is mixed and transported to from the
Fuse Sift to the printer’s hopper.
