Problem with Printing (I get a spiral instead ofmy model)

[Wyom 0]

 

 

Looks like that but it should look like that:

 

I am new to 3d printing (Student),

 

I am currently working on a quadcopter for school and I wanted to print the frame, we have the Ultimaker 2+ in school and I gave my teacher

the SD-Card and he printed it.

Need a hint, how I can  solve the problem.

 

Is it the model or the calibration of the Z-Axis?

It looks like the model warped itself so much that it came free from the builtplate during printing. The head then sort of dragged it along while printing. One thing's for sure: your techer (or the person operating the printer) did not check if the print was off to a good start.

 

The bed may not have been level, or the glass plate may be very dirty/oily. Hard to tell from just this one failed print.
