QR Model Problems

Hello everyone, newbie here:

 

I am trying to create a 3-dimensional QR code model and print it out on a 3D printer/makerbot. I have created a model on creo parametric but when generating the .stl file, all the extrusions and features are lost. It just becomes a flat rectangular prism. Can anyone give me advice here?

 

Also when I create extrusions, they are hollow and not filled. I would like the QR extrusions to be solid filled but I can't do this. Have attached my model.

 

Appreciate the help!

Your extruded QR is a surface. You cannot export to STL using surfaces. Only your block is being exported.

Understood...how would I be able to convert it to a surface?

Whenever I tried modelling it, it always came out as a surface.

Where does the QR geometry come from?

If it's a datum curve, then to use it to make a solid protrusion it can't be self intersecting and I think it can't share corners.

Each vertex in a typical solid sketch must have two and only two segments attached to it. The exception is for thin extrusions.

However, you can extrude curves that share corners as a surface, with capped ends, and then select Solidify.

    I imported an image of a QR code onto Creo and mapped it onto the model. Then I attempted to resketch the entire QR code (4 subsketches for each quadrant) and extrude it. I attached a screenshot of it.

    I tried extruding as a capped surface but it would not allow me to do so.

    That is a lot of work, Sadaf. You will have to go back and close many of the intersections and probably need a lot more sketches. you know you have a closed sketch when it is highlighted with a color for the enclosed region.

    Try copying the sketch many times and make each solid path a sketch and make sure it is closed. This should get you what you are after.
