Difference in Cura between U2E+ and U3E

Recommended Posts

Hi, I wanted to know which hidden setting is the cause for this difference between the number of meters and the print time of the same model, but on two different printers. As you can see, the print on the U3E takes 7h32 min with 9,16 m while the same stl on the U2E takes 6h41 min and 8,70 m.

Both print setup have a grid infill pattern at 20%, the same brim and the same layer height. From what I see, they are identical.

 

I use Cura 3.4 since my computer's software is too old to support the newer versions. I noticed this difference between the printers on other models too. So, any idea on what could be different in this case between the two printers?

The weight of the heads is different, as is the internal geometry of the hotends / nozzles. This means that in order to get the same level of quality, settings need to be different. Usually this means that we have to tweak the acceleration / jerk settings, which will in turn influence the print time.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
