Eventorbot 1.2 bigger build area, 8" x 10" x 6"

Eventorbot! Open source 3D printer.

The Mission and challenge behind Eventorbot, was to build a rigid, low cost 3d printer. Using less parts, easy to assemble, and is capable to self replicate most of its parts. It is 100% open source project, and all plans are available for anyone interested. Since 80% of the Eventorbots parts are printable. Once you build your first machine, you can make it even more affordable for friends, family, or the community. With the single solid steel frame, it eliminates 40% of parts and cost that other 3d printers uses for a housing and structure. Making it easier and more affordable for anyone to own a 3d Printer ("Lets just start printing our own stuff").

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.

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...

UPDATE (10-22-12):

Pic: http://eventorbot.com/pics/DC%20Power%20Jack.jpg NOTE: If you choose to use a hotbed, upgrade this jack to something that can handle at least 13amps. As for your power source, you can use a Xbox 360 power brick. Xbox 360 power brick is 16amp and is more then enough to handle the power (under $20.00).

For Kickstarter pledges who did not pledge for the full kit and have already purchased all their parts.

(For those who are new, ignore this portion. The parts list above has already been updated)

If you pledged just for the plastic parts or the plastic bed, changes needed from the parts list:

Change to linear rods. Instead of:

(6) 10.5" long, 8mm linear rod.

Change to:

(4) 10.5" long, 8mm linear rod.

(2) 16" long, 8mm linear rod.

Change to pexi/glass bed. Instead of:

pexi/glass size: 8.5"(216mm) x 11"(279.5mm)

Change to:

pexi/glass size: 8.5"(216mm) x 16.5"(419mm)

With that little change, your machines Y axis will increase print size by 4" (Your machine will now print 6"x10"x6").

Here is what your machine will look like (googlesketchup/SKP file):


If you pledged for the plastic parts, metal frame, + or - the hot head bracket, changes needed from the parts list:

Change to linear rods. Instead of:

(6) 10.5" long, 8mm linear rod.

Change to:

(2) 10.5" long, 8mm linear rod.

(2) 16" long, 8mm linear rod.

(2) 13" long, 8mm linear rod.

Change to pexi/glass bed. Instead of:

pexi/glass size: 8.5"(216mm) x 11"(279.5mm)

Change to:

pexi/glass size: 16.5"(419mm) x 10 3/8"(263.5mm)

With that little change, your machines Y axis will increase print size by 4", and the X by 2" (Your machine will now print 8"x10"x6").
