Ultra-lightweight proximity extruder design with bi-metal throat construction for extrusion forces up to 70 N. Suitable for high temperature printing at 300°C, especially for flexible consumables and hard consumables such as PLA.
Unique robotic arm design: 3K grade material using the same process as high-end drones. Thickened to 10mm in diameter, high strength carbon fibre rod + aerospace aluminium housing + POM bearing wear resistance. Zero clearance lightweight and high strength design, gathering structural rigidity and positioning in one.
Self-developed levelling algorithm, through 25 points to compensate for machining errors, easily solve the first layer problem.
