Eventorbot! Open source 3D printer. Simple with less materials. Frame is made of a single 4' long, 2 1/2" square tube (16 gauge/1.5mm/.0598" thick, cost: less then $20.00). With this design there is less plastic parts, stronger structure, all wires are hidden, and a more appealing/finish look.
The unit is supposed to resemble a robotic arm with hydraulic tubes. It was designed for prints to be less affected by vibrations. With the 1 solid frame, any vibrations of any axis will cause the other axis to move with it. For example: If the X axis causes a slight
vibration/1mm movement to the right, the Z and Y axis will also move that 1mm to the right. This will result in a better print as everything will remain squared.

great design! what about programming?

jimmerforpoy7 months ago
All together, how much do all the printed parts weigh? I need to know in order print them.
Thanks in advance
profort11 months ago
I agree with robotteen.
robotteen1 year ago
how much would this cost of the project all together? how well does this printer work with smaller parts?

All together, how much did this cost to build?
babu14231 year ago
how do you make the mother board.awsome project man. keep it up
sheitmann1 year ago
Hey Eventorbot, I like your design because of the c suport and the size of the printable area or volume,
but, why havent you created lets say a bigger printer? It´s te same software I suppose.
I´m an architect and i dream with having mi building models printed at full 1:100 scale, without triming aparta every part of it.
When beside kikstarter will we able to purchase one of your printer? or the parts
cmagro1 year ago
Very nice indeed! I found a company which can print the files your provided for us but they asked if the measurements are in mm or in inches :)

Thanks

This is Hans from the Netherlands,
I’m very impressed by jour design, looks slick and simple to construct.
Especially your design solution for the extruder has my interest.
I’m planning to transform my small CNC router into a 3D printer,
Also using the Sanguinololu 1.3a mother board.
Please can you inform me about the geared stepper motor you are using.
The brand and where to obtain it.
Thanks very much, Hans

Thanks Eventorbot, this answers my question.

Eventorbot has met its funding goal!

Well, I'm speechless and overwhelmed with all the support. I will like to say a BIG thank you for all the support, kind words, and to all the backers. To be able to share and have your interest in something I created is a great feeling. Everyone of you guys have made something that was a big dream become reality. Eventorbot, as a 3D printer is now going to happen! You will have no regrets in owning a Eventorbot, our machine will be a strong contender.

Thank you... thank you... thank you...
looks nice! would love to see some step by step documentation of the build. Can you tell me a little more about the specs of the printer? how big is the printable surface, how high? how fast does it print? what's the total cost of materials?
eventorbot (author)  amandaghassaei2 years ago
I'm currently working on video tutorials (http://www.youtube.com/user/eventorbot).
The print is currently 6"x6"x6", this can easily be increase. I have not fully tested its speed. It is currently printing at pronterface's original setting with no problem, and is confident it can print faster. DIY $300-$500.

Awesome! Eventorbot is currently on the homepage of: http://makezine.com/
eventorbot (author) 2 years ago
UPDATE:

Okay, so here is my current plans. I'm going to finish the tutorial videos and plans first (http://www.youtube.com/user/eventorbot should not take more then 3 videos). After that I will contact my metal company and see if they can use their plasma cutter to make the cuts and holes we need for our frames.

For those who do not have access to a 3D printer. I have had experience making molds and using urethane plastic. I will try to make molds of the plastic parts and mold it with urethane plastic. This plastic is very rigid and durable, and is equal or better then ABS.

Note: For those who have 3d printers. The main bed, that supports the linear rods will also be available, as many printers are not able to print it because of the size.

I like your design, it looks solid and simple.
