This is a first view of my own 3D Printer Project for a very Modular and upgradable printer. The UniPrint Mk I (Project Name) is in an early state yet. A special feature is it's extreme modular construction that will allow not only easy upgrades like other Motherboard, LCD or different mechanical components but also a quick-swap system that allows you to change Hot-Ends within just a minute to quickly switch between single or up to triple extruders or different nozzle sizes.
All development processes will be published here and 3D printed Parts of the Printer too. At this time I'm still on technical fine tune a lot of the parts so this will still stay a work in progress for a while. As soon as I'm able to build the first prototype, I will also publish a whole BOM list of all used parts.
Later you will be able to buy pre-assembled kits, finished printed special parts and also upgrade parts. So stay tuned!
- GIANT build volume with 300x400mm Bed and 400mm Build height
- Modular Hot-End mounts to quickly switch between different Hot-Ends types or change nozzle sizes or filament diameter
- Planned support Hot-Ends from E3D like the V6, Cyclops, Chimera and Titan Aero for direct extrusion lovers
- other Hot-Ends possible if desired by community in the future or just design your own mount module
- As ultimate extruder setup, also support for RepRap Diamond (triple) Hot-End is planned
- Easy swappable linear rails and standard sized LM12UU bearing sizes without any further disassembly
- Massive 40x40mm aluminum frame for maximum stability and no vibrations or dislocations
- Strong 59Ncm Nema17 Stepper Motors for core-xy mechanic, to apply maximum speed and precision control
- Dual-Z drive for maximum stability and for easy balancing, just drive the bed all the way down to the bottom by hand
- Premium Motherboard: RepRap Megatronics v3.1
- Custm Marlin Firmware to switch between different configurations, depending on your used Hot-End and Extruder Setup
Also planned Features:
- Option for Laser Engraver or Laser cut (only soft materials like plastics or wood)
- CNC Head for simple milling jobs (also only wood and other soft materials but will check for metal like aluminum too)
- Diamond Full Colour Hot-End (5 Colours at once? Yayyy! Need to evaluate if possible with my planned motherboard)
- ... more to come, any suggestions?
Customized Anet A8 e3D v6
Printed with PLA at 220°C for strong layer adhesion
Speed: 80mm/s with bowden
Shell: 2mm walls and also top and bottom layer
This way prints are very massive and strong
This is the manufacturing of the first prototype parts. You can see the laser cut process for the extruder-change mount plate that will become the X-carriage. For prototyping we made it of 3mm steel plates but in final version it will be 3mm aluminum to be very robust but also lower the moving mass.
Finished Prototype Hot-End Mount plates.
All test printed parts for now. Working at the e3D v6 Mount right now.
Prototype Hot-End carriage with dummy bearings. Cable Ties will be removed with nicer solution in the future.
All needed parts printed for now, exept the bed-leveling mounts. Will redesign them to be more robust. Waiting for main part order now.
Update - 08.02.2018
- Uploaded first version of the e3D v6 Mount Module
- Updated e3D v6 Module to be more massive and robust
- updated clamp mount holes afterwards and also nut holes because forget to do this after making body part bigger
- Uploaded render pictures
Update - 09.02.2018
Designed a big Spool holder with ball bearings to attach up to 7 Filament spools (depending on size) to the side of the printer for easy filament change and multi-extruder use. Spools up to 220mm diameter will fit here.
Update - 12.02.2018
Changed the X-rail Holder and moved the rails up about 18mm (Updated STL). So now the X-Carriage plate is mounted below the rails. This brings more room for bigger Hot-Ends and Fan Assemblys. Also finished the Core-XY Belt mounts. Made some toothed belt mounts where belts can fit without sliding and can be completely fixed with a screw in between both belts with inserted M3 nut. Already printed and tested them and worked perfectly.
Next step is to figure out a good way to mount the plate to the bearings nicely and easy to assemble. First I thought Cable Ties would be ok but it looks like crap. You can see a Prototype Carriage on the Pictures above.
Update - 13.02.2018
Made a simple clamp for the single Linear Bearing on the back side of the X-carriage. Second Clamp for both front bearings will be made when I tested the fit of the smaller one.
Sorry for missing updates!
I'm totally stunned about the huge interest in this project. Never thought that it would get so much interactions and downloads, even in this non-final state.
Unfortunately I didn't had time to work on this during the last weeks because of some private trouble, I have to manage first. I will continue as soon as I can and then, hopefully, build the first prototype! :)
Thanks for your support!

Good news: I found a sponsor who will pay the first prototype build. We will order the full Hardware set (exept electronics, cables and switches for now) in 2 weeks. Updates in this Thing:
- Re-uploaded all STL with newest versions and new Mickey-Style X-Rail Mounts. With these I managed to flip the X-Carriage to make it hang under the rails. Now there is more room for Fans and bigger hot-Ends without loosing build height. (still About 407mm with e3D V6).
- Redoing all renders to have actual state footage
- as soon as I have some time left, I will construct the last X-Bearing Clamp. Should be the last 3D Printed part
Update - 23.05.2018
- Created X-Carriage front clamp for dual bearing
- uploaded STL for both clamps of X-Carriage
- also started printing of all parts in possible final state now
- cleaned up and finalized the X-carriage plate with correct aligned wholes for clamps
Order of all needed hardware will be done diring next 1 or 2 weeks. Then the prototype build will finally start
Update - 26.05.2018
- Created optional in-line belt tensioner. One goes to the left and one to the right, each for one belt. These are experimental because I'm not yet sure if they are robust enough. Let's see when I test print them.
- last design step left before building the prototype, is updating the bed level mounts to become more robust.
- all other parts are finalized for now and printed
- just waiting for the commercial parts to order
