3D Printer Uses Magnets To Break Speed Limits (tomshardware.com) 40

Posted by BeauHD from the time-is-money dept.
An anonymous reader quotes a report from Tom's Hardware: Resin printer company Peopoly created quite a buzz with the unveiling of a prototype beltless FDM 3D printer, the Magneto X, at the East Coast RepRap Festival. The new printer is a desk top machine with a huge 400 x 300 x 300 mm build volume and print speeds up to 800mm/s. It borrows a design feature seen on CNC machines: magnetic linear motors. Normally, 3D printers move their components with rotating stepper motors attached to gears and pulleys. The linear motor can be thought of as a flat, unrolled motor with the "rotor" attached to the moving component -- the tool head -- and the stator forming a track along one axis. Dubbed the "MagXY" system, the tool head seems to levitate across the gantry without obvious means. It has a top print speed of 800 mm/s with a max acceleration of 22,000 mm/s, which would make it faster than modern Core XY printers from Bambu Lab.

Peopoly is using and supporting both Klipper firmware and OrcaSlicer, which founder Mark Peng said greatly helped speed up their development time. [...] Peopoly is leaning hard into the Open Source community. Not only have they become backers of Klipper firmware, they are also using -- and supporting -- Open Source OcraSlicer. The Magneto X's nozzles are compatible with the popular E3D's V6 volcano which suggests the machine will be open to modification by users. Peopoly also states its machine can be used without joining a cloud-based system and promises customer data will not be collected.

    We have linear motors in our solder paste jet printer.
    Accelerates at 3g and shakes the slab.
    It can put down over 200 solder dots per second with a 40micron accuracy!
    but you pay for it!!

      Yes, it will move very quickly, but there are lots of features to make sure it doesn't do that in use. :) I do remember a machine somewhere malfunctioning and stuffing a larger than bore dia patient into a too-small bore. Thankfully, it was another manufacturers machine. :)

        The tapping noise is from magnetic coils changing dimension due to high magnetic flux, it from your body.

    mm/s is a speed, not an acceleration. That should probably be mm/(s*s).
    But this time it's not the editors fault, TFA already has the units wrong. I guess Tomshardware also can't do UTF-8? (superscript 2 [wiktionary.org]: Â)

  • Linear servos have been around for a while. They're not that new, but it was only a matter of time before they were put into 3D printers. As I understand it there are two constructions... you either lay out a line of permanent magnets and the shuttle has the electrical coils, or in the really expensive ones you build a long line of electrical coils and the shuttle has the permanent magnets. The latter has the advantage of no wires running to the shuttle, and supporting multiple shuttles simultaneously on

      Not that unique, either.

      Old hard drives used to use stepper motors to control their head position. The switch to a voice coil motor is effectively a switch to a linear motor - at first it was using a solenoid-like contraption so the heads move in and out like they did on a stepper hard drive. It was only the transition to voice coil motors (a curved linear motor)

      The reason is speed - stepper motors have limited step speeds as well as resolution to pack in the tracks. Using a voice coil means you can positio

    Using linear servos was going to happen eventually, just because it is an effective way to move the print head and all the print head's mass. This is definitely a useful advance. The fact that the printer uses Orca Slicer is "meh", but at least it is somewhat open source. It would be nice if there were profiles for Cura and PrusaSlicer, because both of those have some software features that are nice.

    Overall, speed is important, but just like a car, so is "handling". Overall, I'm glad this is out there as an incremental advance, and maybe we will see it become standard equipment on the next generation of printers.

  • 3D Printer Uses Magnets To Break Speed Limits

    This is a stupid headline. Conventional 3D printers use magnets, too. Electromagnets, sure, but stepper motors work on magnetism, too.

    Furthermore, it's not breaking any speed limit.* There is no law of nature nor rule written that says a stepper motor-driven 3D printer couldn't be faster. One could build a stepper motor-driven 3D printer to match these speeds/accelerations. It'd be crazy loud and wildly inefficient, but there is no inherent physics or

    • Yours is a stupid post. You have absolutely no clue of the relative capabilities of linear motors vs stepper motors. You managed to communicate that fact and nothing else.

  • Speed? In terms of a home use 3d printer I'm much more interested in a 3d printer that prints high detail while not requiring the use of toxic materials so I dont have to set up a special place for it (which I dont really have). It can take all the time it needs if it meets the above requirements.

  • All 3d printers use magnets.

    • Oh wow, insightful. Likewise, both false boobs and computer chips use silicon. So what's special about computer chips anyway?

  • Speed is distance/time, acceleration is distance/time.
