The MakerBot Unicorn Pen Plotter Kit

Introducing the MakerBot Unicorn Pen Plotter Kit!  Add 2D to your 3D printer!

The MakerBot Unicorn Pen Plotter is the next step in the evolution of the MakerBot CupCake CNC line of accessories. It takes your MakerBot in a whole new direction- illustration and pen plotting!

Now you can hold the power of the unicorn’s horn in your MakerBot 3D printer!

Created by our summer engineer Will Langford, the MakerBot Unicorn Pen Plotter Kit will allow you to impress your friends with amazing drawings and more.  It has nice tight reproduction quality, and the images have a beautiful and unique drawn character to them.

You can pick your favorite pens, markers or drawing implements, load your raster or vector art files, and watch your machine draw! It works by holding a pen, marker, swivel blade, or something roughly cylidrical and then uses a hobby servo to lift the implement up and down as your xy stage moves around. It turns out it’s perfect for drawing on sticky notes.

You can make unique stickers, diagrams, UPC or QR codes.  Sudoku puzzles, digital photographs, logos, you can even mark up PCBs for etching!  Its an 299.6 DPI CNC pen plotting system for your MakerBot.

The MakerBot Unicorn Pen Plotter can accept pens or tools up to a width of a fat white board marker. That got you thinking? Uh huh! This new toolhead for your MakerBot that can bring a breath of fresh air into your 3D printer by transforming it into a machine that can make 2D art and more!

    Why the servo arm? Is it faster, more mechanically stable than pushing the z-platform up and down? It probably sounds really neat!

    no wobbling I assume

    I think I’m even more excited that there will now be an in-built 2d path generator. CNC 2d cutting anyone?

    yea the software aspect of this release is really great. i attempted some drawing early on before i got my extruder parts and it was pretty hard. any video of it in action yet?

    it’s unclear from the store page whether or not this kit includes an extruder board (though the thingiverse entry shows that it requires one). is anyone able to clarify?

    All we need now are puppies and rainbows! Are those the next big announcements this week‽ 😉

    @tim noble
    From the assembly page

    “The following things are not included in the kit:

    For running the Unicorn
    pens/drawing implements
    an extruder controller”

    The big questions are when will the ECs available and will they be Gen3 or Gen4 electronics?

    continuous scrolls of illustration if you can somehow incorporate the automated build platform.

    I assume the servo is used because it is a lottt faster than moving the platform. This is especially important for doing rasterized stuff as opposed to just vector graphics.

    Neat hack – somewhat questionable utility, but nifty to see things coming full circle from hacking up old school plotters for early homebrew 3D printing machines to rebuilding them out of a Cupcake!

    That said, I actually kinda wish you guys would space out these new product launches so you could focus on shipping the other new stuff you’ve already launched to those of us patiently waiting to receive our orders. It’s frustrating to get charged within minutes but have to wait week(s) for you to ship my new toys, especially when they were listed as in stock when I placed the order.

    This is not my link but put this lazor in place and control 1w by automatic build platform relay or something heck I would use a new relay just for it.
    reciprocating lazor cutter it could then lazor cut its own parts…
