I have recently decided to purchase Ultimaker 3 becasue of all positive reviews and the features it has.
Ultimaker 3 is perfect with printing PLA. I am printing extreemly small parts and extreemly large and it goes great.
However , i started printing ABS with the default cura settings , but the ABS is not provided by Ultimaker. (Third party , high end ABS).
My print did not stick well on glass, with or without glue. I added a PEI layer on the glass . The part still delaminated sometimes and there was a lot of warping !
