Build a 3D Printer and Take it Home

Thank you for your interest in the build-your-own 3D printer class, however registration for the current class is currently closed.  Please email if you are interested in taking this class in the future.

Have you ever wanted your very own 3D printer? I’m going to give you a 3D printer kit to build and then walk you through the steps of building it, calibrating it, and getting all the settings tweaked so you get great prints. (Please note, this is a special event for Stargate families.  If you are interested in taking this class at The Gizmo Dojo, please let us know at  Also, if we get enough interest, The Gizmo Dojo is going to donate a 3D printer to Stargate, so your participation helps make that possible.

Where: Stargate School (14530 Washington St. Thornton, Colorado 80023) (Room TBD _X_)
Duration: 2 full 8-hour days, Feb 23-24 (Sat 8am-5pm, Sun 8am-5pm)
Cost: $575 (Includes printer, filament, extra tools, good power supply)
Prerequisites: None. Zilch. Zip. Nada. Come one, come all.
Ages: Any, however this 3D printer kit is like an Ikea project on steroids, so some younger kids may have difficulties (also, this is not a toy, there are dangers to be aware of).

The nitty gritty:
To be honest, most 3D printers out there today are not “consumer ready”, in the sense that they always need a little tweaking here or there, and they can degrade over time, and sometimes parts break and you have to figure out how your printer works in order to fix it. Building your own printer is the best way to understand those things from the beginning and set you on a successful path to 3D printing, instead of a frustrating one.
If you’ve gotten this far then you’re probably looking for more details. The printer is a Creality Ender 3, which is a Prusa I3 style printer made from aluminum extrusion. It has 1 bowden print head, and a 230mm*230mm heated print bed. (Don’t worry if that doesn’t mean anything to you). I have also bought new power supplies for each kit (because the ones they ship with are garbage), included a few tools to get you started 3D printing quickly, and included a full kilogram of PLA plastic, which we will use some of during the class but you will still have plenty to take home. The printer uses 1.75mm filament, and it prints at 0.1mm resolution. Last, but not least, the entire printer is open source, so all parts can be modified, upgraded, etc, if you want to explore that option.  If you would like to see somebody else’s opinion on the printer, check out this video:

The class will run over a couple of 8-hour days (with breaks for lunch) and I highly advise you to bring a buddy for this build. This class is very well suited for one parent and one child to work together in order to build the 3D printer.  Kids are welcome but this will be a lot of concentrated build time, so please be aware of that. We will also hold a 3D printer hangout at The Gizmo Dojo in Broomfield a week or two after this class is finished in order to give you some time to print with it and then come back with questions.

If you’re ready to take the class:

We are closing the registration for this class on Sunday, January 27 to give us time to order supplies and have all the printers arrive.  We are limiting this class to 10 3D printers (20 students), but if there’s enough interest, we will hold another class in the future.  If you have any questions, please email and I’ll be happy to answer your questions.

I am very excited about this class, and I am looking forward to getting a bunch of 3D printers running!
