HOW IT CAN HELP
The Fuse’s build chamber is similar to the purpose of a resin tank – it deposits powder onto a heated aluminum plate to fuse into solid layers with a laser. As the print advances, the bed moves down into the build chamber. An IR sensor is used to monitor the print bed, powder, and layer temperatures as the product is printing. It uses the data to drive the heaters and thermally stabilize the printing environment. The Optical Cassette protects the laser window and camera lens from off-gases produced during printing. A set of LEDs illuminates the print enclosure to improve visibility of the bed during printing. Unlike most SLS printers, the Fuse draws in surrounding air through a filter to keep everything at a constant temperature, which helps prevent parts from warping due to thermal dissipation. Another feature that sets the Fuse apart, is that it uses thermoplastics rather than thermosets, powder rather than liquid resin, all while coordinating everything around 180°C during a print.
The Fuse 1 is also low waste. A 30% material refresh rate means you can print with up to 70% recycled powder, indefinitely. Fuse Sift’s sieve filters out particles to be remixed with new powder and reused in future prints.
