I have a CR-10 that im using currently and a prusa i3 that i don't use anymore. The thing i like about the CR-10 is the build volume. Making armor we usually need to print large things and a larger build volume means less seems. Speaking from experience because I made my mark 46 entirely on the prusa i3 and there was a lot of pla welding. Something I dont like about the CR-10 is how loud it is. I installed vibration dampers on it and the thing is still keeping me up at night.
I made this suit with the prusa i3
And these projects were made
with the CR-10
