How do I change the print parameters for an object?

Currently, all print settings are changed through Once you have uploaded stl files to your account there are a few settings that can be changed before it gets downloaded to your printer.

For this guide we are going to use an elephant, but these steps are not specific to this guide, as they apply to any and all objects you may have.


1.)  Click on the project folder and select the object you want to be changed.

2.)  On the pop up screen, select either the cube in the upper right hand corner or the settings in the lower left have corner. The cube will allow the object to be rotated on X, Y and Z Axis. By selecting the settings on the lower left hand side, the print settings can be changed. If the object selected is not wanted, click the delete button to remove this from the project folder.

3.)  Rotate by click the X, Y or Z axis until the object is sitting on the build plate as you would want it to print on the Simple Bed. Save the file by clicking the “Save” button on the bottom once you have acquired the correct rotation.

4.)  Once you’ve selected the settings already loaded, the window changes to the Print Settings options. You can change the resolution of the print from Low to High resolution by selecting the “Resolution” drop down bar. Low resolution is set at .2mm, Standard being .1mm and High being .06mm. The infill drop down bar gives you the options of Hollow, Light, Standard, Medium, Heavy and Solid. Light is set at 10 percent, Standard being 20 percent, Medium being 40 percent and Heavy being 60 percent infill.

Other options available here are Print Support and Print Brim. Support will give you added material if there are overhangs that will not be otherwise possible with printing. Brim is a setting that helps secure the print to the build plate by adding material around the base of the print (more surface area).

5.)  Make sure your printer is connected to the network, and the app is registering the printer. Once all the settings desired are updated in the project folder, send the project to the printer by clicking the “Send to Printer” button. If the project is currently on the LCD screen on your Simple, erase the project and resend it through

6.)  If you want to change temperature, retraction and print speed among other things, select the filament tab on the upper left hand side of the page. This will bring you the the Materials Library. 

7.)  Select the “+” sign on the bottom in order to add a new custom filament to the library. Change the settings of current filament by clicking the edit button on the far right of the filament.

8.)  Create a new material for your library or edit an existing one, either way, change print settings through this feature. All temperature settings preloaded are in accordance to general specs of the material. Speed is something that can be adjusted to print faster as desired, but is intended to print slower for trickier materials like Ninjaflex. Adjust this setting with 100 percent being the average speed; 50 percent is half speed and 200 percent being double speed. Some filaments don’t want a print fan, so the option is there to turn this off. Retraction is also something that most filament will want in order to have successful prints, but take it off if you think it’ll work better. Tweak any of these settings and save them to the library. In the main page, click the “Send to Printer” button in order to overwrite the existing materials library on the Simple.

    Is it also possible to change printing speed? I have set the infill to hollow to print a spiral vase and the printer goes so fast the filament does not stick to the build plate. The priming line is perfect and adheres very well, it's just that it goes slower.

    Hi Vinz,

    To do that you'll want to use the features in the full version of Cura and print via a USB cable.

    Hi Eric,

    Thanks for the feedback. In the meantime I also saw there is a speed setting via the material library so I guess I could tweak that there.

    Understood for the full Cura version. Fortunately, you guys have put the ability to upload gcode to the Printrbot cloud so I'll likely use that (easier than doing a firmware update needed to print tethered).

    Another useful setting would be to change the print size (scaling). When doing test prints, it is useful to not use the full build plate size and scaling is needed.
