Solidworks for 3D printing

I am a SW maker who uses SW for woodworking and recently purchased a 3D printer.  I have two grandsons in the UK and want to teach them how to use the same printer I purchased for them.  I live in the US and will travel to the UK later this year.  Can they get SW for makers or students in the UK?  I would like to teach them SW instead of other 3D drawing programs.

Is this realistic or should I learn another program to teach them?
