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 under 300€. The most expensive parts are: rails, 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 ESA/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 Host.
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 too problems in nature. He's not here anymore, but his 30 yr old fishing silk, is still as good as new. And does wonders. Thnx dad. And thank you moth's.
The silk does not slip around the motor's pulleys because they are 3d printed in TPU (flex filament).
UPDATE 12th of april 2018
Happy like a kid on christmasmorning. Our Printed Foldie exceeds all expectations.
Fast, extremely accurate, 0.05mm on x&y!! and as stable as an I3.
Vid coming soon, I'm not a cameraman, it appears...
We will revise the most expensive parts, like the controller board, in the hopes of bringing you a more affordable, capable, 1board solution for any 3D printer.
Our goal here is to create the next "RAMPS" along with Foldie. In the same pricerange, but on a single board.
UPDATE 2nd of may 2018
Currently looking at the new controller design,
So far it is a 32bit controller board, similar to the Duet range.
This because we appriciate the cost effectiveness of this pocessor architecture, in comparison to the 2560 architecture.
*The main diffrence is that it has USB as well as Bluetooth connectivity****.
And for good reason. 90% of phones these days have WiFi as well as BT.
When looking at 3D Printers current connectivity, i noticed most go for giving the printer Wifi. Internetconnectivity. Octoprint, Duet Wifi and more are examples of this. I get why. you can attend a happening, and check your print over the internet.
But (1)is that of any use when things go horribly wrong? When your printer catches fire when ure at work, or school? Lets all just agree, that a smart person doesnt leave his 3D Printer unattended, As stated in every machinery manual on this planet.
And(2)when home, and your printer is via wifi connected to your phone, this phone, cant do anything else. Its enslaved for the purpose of connectng with the printer, unless one takes the web-browser-approach.
In Our Controllers case, the printer is either host-controlled by USB and PC, or BT and a Phone App. Wich suddenly gives you the wonderful ability to host and control your printer over BT, whilst browsing and slicing files online, over WiFi.
*It eliminates the cost and config of the whole LCD Display story too.
The second main point is that is is a single extruder board. This mainly out of financial considerations. But also cause there is no competent, compact, affordable, and legit 'starter' board out there. (chinese usb drivers and closed source designs dont count in my book)
When starting with 3D Printing, its gonna take a whole lot of time before you mastered enough experience to even try dual color anyway. The fact is that it takes a lot of understanding of the technology to print dualcolor succesfully. So, making a controller board more expensive by adding multiple extruder-components on the board, seemed costly for no good reason. Foldie isnt really intended for DC printing anyway. That doesnt mean that there aint no idea too make that a reality. There is an empty space for another extruder motor on the back for a reason. Its just costly in time to work out this 'better system' then the current ones. The trick would be in the printhead and the slicer. As for the minimalist functionality, the board does have more then enough expansionpins. As with most boards, we didnt wanted to deprive makers from any hacking option.
Also, the board is supposed to be a cost effective single board replacement for the RAMPS family, adding options that are perfectly accomodated by existing boards would be redundant, and make the board fall out of the financial capacity range of our main public: students..
The board will have the ability to be powered by the 12 to 24v range.
It also has the ability to make use of a separate 5v Power supply. This to avoid the damage of the voltage stabilizing chip on the stepper driver when emergency stop(reset) is hit.
In the time that it takes to finish the board into an endproduct,
We are setting up the website; foldie3d.com
We are aquiring all media. Photosessions, video, and editing is harder then it looks :s
Printed files are made ready(uploaded, described, equipped with pics, and printing info)
The assembly manual for the printer is being made.
UPDATE 11 June 2018
Previous update stated the controllerboard would have onboard wireless capability;BT
This has been revised to an Optional BT module, again, to keep costs down.
Initially we intended for smartphones too control the printer over USB, immediately adding WiFi/BT/3Ginternet capability.
So adding wireless to our board,
-is again, costly for no good reason,
-still optional by adding modules on the expansions
-And redundant, cause its big brother board (Duet 2 Maestro by Think3dprint3d & Escher3d)has all that and more.
UPDATE 11 june 2018
I just noticed, i never mentioned Foldie has a magnetic quick release extruder assembly.
I'll post some pics later, but it enables the printer too remove its printhead before folding up, and one can change extruder heads in about 30 sec flat. No more pliers, cramped positions, and messing around to change a nozzle, or fix a clog. Like the Tiertime UP! 3Dprinters had, but better 0:-)
*We plan to use https://www.gofundme.com as crowdfundplatform because others have too limited payment solutions for students.
