The ease of use, speed to print out models for my students (and myself), ability easily export STL files into other CAD programs like SolidWorks or CATIA etc., price point is great! I wish that there was more control over how much material you have available when printing your model but this can be mitigated if needed with additional filament cartridges/filaments purchased from them directly through their website as well. They offer free shipping so it's not too expensive either way and they are very customer service oriented which makes working together smooth sailing at all times!!
