Belgian 3D printing start-upFuselabhas launched its first FFF metal 3D printer, the FL300M, which features a patented rotary extruder designed to enhance metal powder-based filament printing.
Produced at FuseLab’s Belgium facility, the FL300M will make its debut at this month’sFormnext法兰克福的贸易展览会将于2022年初出售。
Improving FFF 3D printing
Despite being around for decades, the FFF 3D printing process is continually being improved in order to最小化部分不规则,改善粒子发射率， 和optimize inter-layer heat transfer and adhesion. In fact, established 3D printer manufacturer3D Systemsreleased itsfirst industrial FFF 3D printing system仅在今年，构成了其高速融合（HSF）平台的基础。
Fuselabwas founded in 2018 by Jonathan Palmaers, inspired by 3D printing’s potential and seeking to address areas of improvement within the technology. The company began by developing its patented rotary extruder, and after realizing its prospective benefits for metal printing began working on the FL300M.
Fuselab’s facility is equipped with in-house engineering, prototyping, and manufacturing capabilities and operates on a closed-loop system that enables rapid development cycles and enhanced product quality control.
The firm’s first FFF 3D printer, the FL300M, distinguishes itself from others in the crowded FFF marketplace thanks to its novel patented rotary extruder, coupled with a high-performance and precision motion system.
Traditional FFF extruders tend to feed filament into the printer’s melt zone with one or two drive gears, which provide only one to two points of contact between the drive system and the filament. At higher speeds or extrusion forces this can lead to ‘slipping’ of the filament and subsequent under-extrusion.
With its patented extruder technology the startup is ultimately aiming to raise the quality and reliability of FFF metal printing.
虽然获得专利的挤出机设计是FL300M的展示，但该机器还提供了一系列其他值得注意的功能。该打印机配备了300 x 300 x 280毫米的构建体积，能够打印多种材料，并针对金属粉末丝进行了优化。
The printer operates on an open filament system with filaments of 2.85 mm diameter, while a rigid motion system uncoupled from the build enclosure is designed to enhance the printing process. The machine also features an enclosed build chamber with HEPA filtration.
FL300mwill make its debut at Formnext 2021, and will be available in early 2022.
