BIQU Hurakan FDM 3D printer
The new systems are initially ground up for the advanced functionality of Klipper firmware and feature 32-bit electronics with additional processing power in the form of a quad-core single-board computer.
Hurakan relies on a 32-bit Manta M4P board designed specifically for the Klipper. The board, featuring an ARM STM32G0B0RE microcontroller clocked at 64MHz, works in tandem with the CB1 single-board computer with a 1.5GHz quad-core ARM Cortex-A53 processor and 512MB of DDR3 RAM. Quiet TMC2209 drivers help keep noise levels to no more than 50dB.
The system supports Wi-Fi, Ethernet and USB connectivity, with optional ports for the ADXL345 accelerometer housed in the head. This allows the use of a vibration damping feature that helps print at speeds of up to 150mm/sec and acceleration of up to 3m/s^2 with virtually no "chime". For purely aesthetic reasons, there is also a built-in RGB backlight for the print head, with almost seventeen million possible colours. The X- and Y-axes are fitted with belt tensioning mechanisms.
The platform is aligned using a 'micro probe', a miniaturised aluminium contact probe weighing six grams. The probe can be purchased separately for installation on other 3D printers. The platform has zoned heating: depending on the size of the products, the entire stage (240W) or just the centre section (100W) can be heated to save energy when 3D printing smaller models.
The build area size reaches 220x220x270 mm. The Bowdenfeed full metal extruder is equipped with a filament sensor and supports polymer printing at temperatures up to 260°C. If desired, the extruder can be replaced by a high-temperature H2 extruder. These extruders, which are available in both air- and liquid-cooled versions, accelerate to a maximum temperature of 500°C, theoretically allowing printing even with refractory engineering thermoplastics such as PEEK, although the lack of a temperature-controlled chamber is of no help. On the other hand, the H2 is already a direct extruder and is better suited to thermoplastics than the stock 'bowden'. In addition, the higher hotend temperature will ensure reliable extrusion of glass and carbon filled composites.
The on-board interface includes an IPS colour display. Alternatively, the 3D printer can be controlled via the Fluidd web interface or Mainsail with support for several machines at once if it is a farm.
