Foldable , Portable ,3D printable, Green, Fused Filament 3D Printer.
Designed for students.
If it reaches 100+ Likes Here on Thingiverse, I'll crowdfund the hardware parts in a kit.* Printed parts stay free!

We hope to present our final version soon,
check out the new low-cost extruder we designed! (very last pic)

Foldie is recently on facebook. look 4 "Foldie3D."


As long as u don't profit from it, please share, and adapt as u see fit.
This printer is designed especially for students.
No 3D printer in the world is so portable, it fits in a laptop-bag,
and can be build for under 300€. The most expensive parts are: extruder parts, electronics board & power supply.
this printer can be assembled out of wood, plastic or metal, but i originally tried to design it so every part would be 3D printable.
Except for 6 glider rods, a threaded rod, 4 stepper motors, some screws, bolts, washers, wiring, and electronics, i succeeded.

Maybe an idea for Nasa ... takes up less space & weight on the way up :-p

Work in progress:

  • I plan to use an Android smartphone of some sorts in the future too communicate and control the printer. It would also go on the back, in clips that pivot, facing backwards, and fold open until its next to the printer facing forward. that would allow for a 50-70€ stand-alone, wireless, 3G enabled, schoolworthy 3D printer controller.
    Android apps are easyly build, managed and learned, and a smartphone has usb to communicate with the printers Arduino-based electronics board. So why not.
    My motto:
    "If u can imagine it, u can make it"

If this reaches 100 LIKES, i'll crowdfund it. So please SHARE.*

Special thankx to
for redrawing & printing the gears of the bed lift.

UPDATE as of 27/03/2015, Foldie has no sideplates anymore.
the benefits of our new design eliminated the sideplates.
Instead, foldie has now a Foldie-worthy foldable constuction at her sexy bottom sides, wich locks her firmly into place when opened.
Her brandnew designed, multi-diameter spool holders,
are the magnetic-locking crown on the design.
take a look at her drawings, next week we'll post some new edition pics.

UPDATE as of 19/08/2015
In order 2 improve stability while printing, Foldie's extruder motor goes on the back from now on (like ultimaker, reprap,...). the extruder motor movements on top proved too rough for a lightweight plastic frame.

Last but not least:
Please only use ABS if necessary.
Think Green ;) i don't want my Thing to pollute the planet any further. on the contrary. i spent several months! researching suppliers eco footprint, calculating power usage and what not. Please carry on the trend.

UPDATE as of 19/01/2016
Several boards are being tested now the frame is sturdy & ready.
Power supplies are considered and tested.
Nylon support for heated beds is being tested.
Inquiries have been made for a sheet metal alu model.
As soon as the board satisfies me, i'll show a vid of Foldie printing...

Foldie Rail test X & Y

*We plan to use https://www.gofundme.com as crowdfundplatform because others have too limited payment solutions for students.

Is that a pic of a heated bed? Does that mean you'll be supporting it?

yup. Both firmware with and without heatbed functionality will be published.

New revisions look awesome!

tnhx, not done yet. LM6UU system was completely useless, and this Hiwin rails are too expensive. they bring Foldie's total cost at our initial retailprice.
Have two ideas left, If they do not work, Foldie becomes more expensive then anticipated.

Hey, I built the SmartRap printer recently and I found some awesome linear rods for only a few bucks in lots of sizes.
Here: http://www.amazon.com/dp/B00CNM6RFA/ref=biss_dp_sa1

If you haven't already, then you should checkout McMaster-Carr, and Openbuilds. Their parts come at an extremely low cost, and are very high quality.

good tips ;)

This, honestly, is THE most amazing thing I've ever seen on thingiverse and really should be featured. I am 13 years old and have a 3D printer, but my parents are also separated so I bring my printer back and forth and it's a real hassle, so this is on my "To Build" list. I have two questoins: 1. When will the parts (from the STL's to the hardware) for the printer be released, and will the extruder and board come with it? 2. I really love the concept and design, but will it be able to have a heated bed? Thanks, and I really look forward to the outcome!

Hi smiley 424, thank you. We know the back and forth feeling ;). Hang in there. Foldies parts will be free for download, and a hardware kit will be crowdfunded with all 3D hardware parts as hotend, board, motors, borosilicate glass bed, bolts n screws. The heatbed will be optional. 1. it requires a seperate power supply. and 2. its actually useless and a waste of electricity to heat such a small surface. As 3D Systems prints cold with glue in ABS on her Cube printers, we can too. But it will be additionally available in a self adhesive silicone heatpad and some PEEK parts

Truly awesome work! Maybe you could collaborate with makerfarm or one of the other vendors to get a pre-packaged hardware
kit set up. That would save people who want to build the time, trouble, and expense of finding and ordering the necessaries from a bunch
of different sources.
Thanks for sharing your work!

are the files available?, i only see a single STL of the whole machine...

its still a work in progress. there still a couple adaptions too be done. nearly there. just a tiny bit more patience ;)

could you post a video of it printing?

youtube channel is in the make ;)

how big is the buildplate?

max 160mm for this scale foldie,
