Cura is a complete slicing solution for RepRap 3D printers. It contains a 3D model preview, GCode generator, and GCode sender in one easy to install application. Designed to make 3D printing easier and more fun.


Cura started out as a free-open-source hobby project for the Ultimaker. As a cure for ReplicatorG with Skeinforge with it's 260 configuration settings. Many people liked it for it's simplicity and ease of use. So Ultimaker hired the developer of Cura to develop it faster and furter. Now Cura is the offical software from Ultimaker.

This does not mean people with RepRap printers are left out, it still supports any step-extruder based machine that supports 5D GCode. And many people are using it on their Prusa Mendels or Printrbots.

It also means that Cura is by no means going closed source. Cura is and will remain Open Source. Latest developments can always be followed at the main repository: https://github.com/daid/Cura

It does mean that Cura is going to get better and better all the time. With new features and fixes.

love Cura,, I've tried a few different programs and Cura just works,, Only thing I would like to see is the quick print settings perimeters be adjustable to each machine.
Thank you Daid and Ultimaker for all your efforts and a great program

Cura and Makerware, which slicer is more efficient?

nice, i notice a lot faster fill processing in this edition then in 12.11 specially for 100% fill.

Well done Daid, cura takes out alot of the hard work of trial and error printing, help beginners hit the ground running

Great work, thank you!

Has some real nice features ('hop' seems great idea!), but unfortunately I won't use the new 12.12 it since the option to manually position a print on the bed has been removed :(
Will have to keep using older Cura version I guess... Hope they'll add it again in future version.

on gnu/linux where do I put power after downloading it ?

You can put the power in the Cura directory, or install it with http://setup.pysetup.py as a global python module.
I know Linux installation support is sloppy at best right now. But there are so many Linux variations and 97% of the users are using Windows or MacOS.

Thanks Ultimaker for not going makerbot on the community!

Btw, do you guise live up to RYF (http://www.fsf.org/resources/hw/endorsement/respects-your-freedom)http://www.fsf.org/resources/h... ?

Looks like we mostly live up to that, except for calling Linux. Just Linux and not GNU/Linux, and that we don't have a bounty program.

We are not large enough, and too busy already to do any official certification like that. But we believe that staying open will push innovation, and we like to keep innovating.

is there any way to move it around the bed, and not always be centered?

no, but you can move the center it places things on, giving you the same effect.

How? The previous version had a machine centre option but it seems to have disappeared in this release.

The machine center option has disapeared, it always centers on the midpoint of the bed now, you can adjust the machine size in the preferences (which adjusts the center as well)

That is a little problematic for a rostock where the centre of the bed is 0,0. It works if the machine size if 0,0, but that screws up other things in the previewer.

I'm aware of the RoStock problems and will add a special setting for that ;-)
