Peopoly’s First FDM 3D Printer Has No Belts
The new Magneto X stands out for its linear motors, a novel motion system in consumer 3D printers that does away with belts, pulleys, and the stepper motors to drive them.
Peopoly has announced its first FDM 3D printer, the Magneto X, a 400 x 300 x 300 mm Klipper system with linear-motor-based kinematics the company has dubbed “MagXY”.
Linear motors differ from more typical stepper motors by their straight (linear) motion, unlike the rotating motion of stepper motors. Because of this, guides can be attached directly to the motors, making linear motors a direct drive motion system that eliminates the need for belts and pulleys.
That could be a great boon to producers looking to minimize 3D printer maintenance. So why haven’t linear motors cropped up on consumer printers before?
“Linear motors are costly, complex, and lack a broad supply chain and software support,” said Peopoly founder Mark Peng. “While they offer high precision and speed, many argue that it’s overkill for a printer with a 0.4mm nozzle diameter.”
That precision is 0.3-micron, according to Peopoly, potentially putting the Magneto X in the same league as resin 3D printers with the right nozzle. Meanwhile, the claim of a jaw-dropping 800 mm/s print speed and 22,000 mm/s² acceleration promises the machine to be very fast – more than double the speed of more typical stock consumer machines.
The system is rounded out by a load cell sensor in the print head for its 48-point automatic bed leveling carried out by four independent Z-axis motors. It features an extruder Peopoly has named the “Lancer” with 90N extrusion force and a “variable-length melt zone” capable of printing at up to 300 °C with a maximum extrusion rate of 60 mm³/s. On the cooling side, a “Jetstream” auxiliary cooling fan helps achieve those zippy print speeds – side enclosures and a top cover are offered separately,
The Magneto X will retail for $2,000, but pre-orders are on offer for $1,399.
