Introduction: Multimaker Prototype #1

Feb 2020 UPDATE: This instructable was taken down since the first project didn't go well...This was my first major project, and i published the instructable even before i finished it lol!! i basically started the car in 5th gear. In my defence i was 15 back then in 2017. After a few months of learning from my mistakes, i designed and built a normal corexy 3D printer which did work well. Around the same time, E3D announced the toolchager concept. which is basically multimaker automated. I didn't ditch the idea and built a toolchanger with 3d printed parts (IG / Twitter link ) before E3d released the files. Now, i gotta update it and make it compatible with the E3D standard. I've left out the introduction part for archival purposes:

In this instructable i will guide you through the process of building Multimaker , which is a large 3d printer + PCB maker + light duty CNC router + Laser engraver + MORE....( cnc platform with modular toolhead )

A 3D printer is a great tool for people ranging from consumers who use it for printing things for printing things for everyday home needs, to makers who use it to materialise their project ,to corporations who use it for prototyping and sometimes even for mass production . one printer may not suit every consumer, a maker class printer may not suit a professional or a home user . The printer i'm talking about ( Multimaker )

If you have not heard about 3d printing or you don't have considerable knowledge about 3d printing or even if you are curios i highly recommend you to enroll in the 3d printing class on instructables before progressing Because:

No printer suits everyone that's why I made this instructable so that you get instructions for customizing Multimaker to your liking. so that it virtually suits all makers

now with that aside, lets talk about Mulitimaker , i named it so because:

  • - it can do high quality FDM 3D prints
  • - it can print at high speed
  • - it can make PCB
  • - its a light duty CNC router
  • - its a CNC plotter
  • - it can do laser engraving if you add a laser

in short Multimaker is a multi purpose CNC platform it can be expanded to do SLA 3D printing and much more , it can be done in a way similar to which Maker arm does it

WHY ALL IN ONE RATHER THAN SEPARATE MACHINES?

That's the main point of Multimaker , there is 2 reason why i made Multimaker rather than separate machines

1 : cost - buying separate machines cost thousands of dollars

  • For example : a good budget fdm printer like the Prisa i3 mk2 cost 699$ - 800$ .A cnc machine like the Othermill cost about 3000$
  • Even of you decide to make separate diy machines it would cost about twice the cost of Multimaker
  • Even all in one machines like the boxzy cost thousands of dollars
  • Multimaker cost below 500$

2 : space - if you have a small garage then Multimaker is perfect for you it takes up half the space of separate machines

this can be done because almost all of the above is basically 3 axis (x,y,z) controlled by a microcontroller .The trick is to build a motion system with a modular tool head and tune software to do it all

Multimaker specs:

  • ~300x300mm build volume
  • 500x500 mm size
  • 5 micron xy resolution
  • print speed- 10- 100+mm/s (limited by 8 bit Arduino)
  • bed leveling - contact bed leveling swappable tool head

Step 1: Software, Design in CAD

Step 2: Frame and Motion

    Step 3: Electronics

    Step 4: 3D Printing

    Step 5: Wiring

    Step 6: Firmware

    Step 7: Let's Print

      its constantly being updated

      Multimaker prototype 1.1 is being made

      the revisions include :

      - new carbon fiber x gantry

      - new xy,z linear guide with lm series bearings and sintered brass bushing on steel and carbon fiber rods

      - new z axis arrangement

      - new extruder

      -new quick removable build platform

      i just ordered the parts needed from banggood.com for the design revision

      it will take about a month before the revised version is ready to print

      if this prototype works flawlessly it will be the completed Multimaker 1

      Most impressive; I have been 3D printing for about 4 years now and I don't think I've ever seen a z-axis quite like this - points for originality (and for not cantilevering)! I'm looking into Marlin for a similar machine I'm designing, but if it's any help I have used Grbl in the past and it has some built-in functions for laser operation (I think they're related firmwares?). Anyways, amazing work and I look forward to seeing it in action!

      -boxzy uses the same z axis , i used it because its proven to work with a cnc router as well as a 3d printer which boxzy is but boxy costs 2200 dollars

      (you can see the z axis of boxzy in the image )

      -i am thinking of upgrading to a dual z axis where the z axis is supported by two lead screws on left and right and by linear bearing on all 4 corners of the bed

      -i used marlin because its damn popular, but its actually designed for 3d printers

      to use it for cnc and laser, we will have to use a post processor for marlin

      a video will be out when the develepment of Multimaker is over . now multimaker is constantly changing

      Hi there Devadath! I just want to motivate you to continue and keep up your idea and concept. Your instructable is really nice and rich in content for those who want to build a machine from zero, like I did.

      I gathered the essentials and printed the rest with my chinese delta, the money wasn't really a concern because I was able to buy the needed parts, not all at once, but monthly. I tried to build in wood and balsa three times without success, only the second version of the actual frame was a done deal, and now it's my daily printer, since jan 2017.

      The $300 target price is nice, when you think in a 3D printer, because if you add a good splinder a worthy laser module, it will pass that prince point.

      Hope to see your machine in action, and once again congrats for the instructable and for the info research that you have done.

      you are correct , a laser will bust my budget of 300$. I didn't buy it yet ,

      I will buy it later if I need it but I can provide instructions to set it up

      Dude, sick project! I would love to build somthing like this! A video of it in action would be really cool! You should check out my 3d printer that I made out of Legos in the 3d printing chalenge! votes would be appreciated! My project is no where near as sophisticated as this but I had fun with it! Awesome Job!

      when will you be home to make a video? i love this and have been looking for a great diy combination cnc-3d printer with pcb milling. i absolutely want to build this. fantastic job!

      i will be home by next week , I know a video would make this instructable much more awesome . If you find it difficult to wait for a week , hypercube by tech2c has a similar motion system ( corexy ) and it's already available on YouTube

      Link:

      Hypercube by tech2c is a great 3d printer he also included STL files for the printed parts of hypercube , if you decide to go with a t slot or v slot frame those files would be useful, watch this video till I upload Mone so that you would get an idea about multimaker

      As said a french humorist, "Mozart was only seven years old when he created the 5th symphony of Beethoven". You're eight years too old, but congrats !

      did you make it all by your self cuz that looks like it would take some funding

      Yeah I did it myself it took me ~300$. Which is very cheap for a 3D printer . My parents funded my project

      very very impressive. documentation looks good and that is a definite plus. I have built a table top cnc, been thinking of converting it to 3d print. you gave me info I was looking for. thankd

      if you like to do CNC and 3D printing , and if you got the right electronics you can Make your CNC a Multimaker by changing the mount in your CNC.to the mount I mentioned in the instructable and use crimp connectors near the toolhead for wires coming to the toolhead it allows you to rapidly switch between 3D printing and CNC milling

      this is a great document on how one could "possibly" build this idea, but I'm wondering exactly what you built for that $300 price point. Pricing this out according to your suggestions, and this build is nowhere even close to the budget $300 you describe.
