The ability to make prototypes very quickly, at low cost (compared to other prototyping methods).
It's easy enough for beginners but also offers advanced features that are useful in more experienced users as well! I haven't used any of their software specifically yet so can not comment about how good it is or isn’t compared to others out there. However from what i have heard they seem pretty decent all rounder - if you need something fast then this could be your go-to product! We've been able print some parts we needed really quick using our own machine which was great. Also being able to use multiple materials has saved us time by printing only one part before finishing off another piece instead of having two separate machines running around doing different jobs.
