Well, I started 5 years ago with some project that required custom printed protective casing form multiple cameras, used to make high altitude imagery on stratospheric probe. More recently my team used 3d printers to verify some highly complex structures for stress testing. We used a lot of software - from slicers like Cura, Voxelizer, Z-Suite through Blender for modelling, some iterative model building software and others. So far I used Zortrax M200 printer that currently undergoes some extensive modifications to better support a wide range of materials. Second unit that I used is ZMorph SX - which has some really nice features with some that I still should look more into (especially printing ceramics).
I wish I had enough money to get myself something like new Prusa.
