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!
Help speed up the development by tipping the designer or donating through https://www.paypal.me/3DPrintersVDB
Every contribution, in whatever form, will be noted on foldie3d.com with the release on gofundme.
We hope to present our final version soon,
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 the linear axles, 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.
"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:
Foldie is COMPLETELY* printed in BIODEGRADABLE PLA.
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...
UPDATE 21/03/2017 It seems to be a point of anoyment, to manually re-calibrate the bed, each time, after foldie has been mobile. So i thought of a solution, what woke me up mid-night, only to discover online, i wasn't the first;
The hotend is mounted on a slightly flexible mount, which presses upwards, when touching the bed, closing the Z-endstop right above it, what, in turn, allows for non-capacitive, low-cost, multi-point, printbed calibration, each time after a power up, after the print-command is given.
The bed has gotten aluminium u-profile bed support.
This to account for the slight flexibility in printable polymers, wich would be nefast for a bed-support.
some axle rails are replaced with Igus products, in order to win space, reduce weight, and reduce cost.
Yaxle glides on HIWIN
Xaxle glides on IGUS
Zaxle glides on IGUS
In the last update we stated that the Z would have IGUS rails. It won't.
the directional torque of the horizontal bed on the vertical slide proved too much for smooth movement. It has been re-equipped with the Rods and LMUU06's bearings.
The actual update; the transmission of the CoreXY is done by fishing silk.
Not a nylon infused belt. they were heavy, wide, and their resistance when bending and stretching had effect on the small operating space. The fishing silk is relatively cheap, (less then toothed belts/mtr) UnBeLieVeaBle Strong, doesnt stretch, in comparison too belts, is relatively naturally produced in mothfarms, biodegradable, and commonly available. Also, it withstands time when not in operation. The silk on our prototype was my dad's. He taught me too look for answers to problems in nature. He's not here anymore, but his 30 yr old fishing silk, is still as good as new. And does wonders. Thank you moth's.
The silk does not slip around the motor's pulleys because they are 3d printed in TPU (flex filament).
*We plan to use https://www.gofundme.com as crowdfundplatform because others have too limited payment solutions for students.
