Posted · Object Imports Smaller

Hi

 

I am new to printing and have a Ender 2 pro. 
 

when I import a STL file into ultimaker cura it shrinks the one object in the file I’m guessing to fit the printer I have.  Is there a way to import a file without modifying it at all?

    STL files don't have units equivalent to real world units - they just use generic ones. The usual convention is that 1 unit = 1mm but not all software outputs at that scale, so it could just not be importing large enough.

     

    To make sure the size of models is not changed when loading an STL into Cura, go to Preferences > Configure Cura, in the General page there will be a Opening and saving files section, and in there make sure Scale large models and Scale extremely small models are disabled.

    (IIRC scale large models is disabled by default but I could be wrong)

     

    To resize an object once you have it in Cura, select the object and open the Scale tool on the left toolbarimage.png.10bd5d79d740ae4170bf2325cc7e3a91.png.

    You can then enter the dimensions manually in the box that comes up:

    or you can click and drag the handles on your object:

    If you know exactly what size it's supposed to be, entering the values in the box on the side is much easier.

     

    Please bear in mind that if a model is larger than your printers' build volume then you'll have to scale it down to fit anyway since Cura won't slice anything which doesn't fit in your printer. To print a large object in multiple parts, you'll need to use other software to split it into multiple files (if you use Windows, Microsoft's "3D Builder" app is actually really great and can do that easily).
