Print time goes down when print speed decreases?

Recommended Posts

Hi everyone,

I have been messing around with settings on Cura to see what kind of effects occur in an attempt to find optimal print settings. However, I noticed something unusual when changing the outer and inner shell speeds that I have been unable to find an explanation for. When lowering these settings below their default values, print time actually decreases instead of increasing.

For example, when the outer shell at 30 mm/s the estimated print time is ~9 minutes. But when the print speed is lowered to 10 mm/s, the print time decreases to ~6 minutes without changing any other settings. These predicted times are matched by my observations of the printers speed- it seems to print noticeably faster on 10 mm/s than on 30 mm/s.

As I said, I have been unable to find an explanation for this phenomena elsewhere on the net. The best explanation I can think of is that the this a glitch; perhaps a decimal point is being added to low numbers (i.e. 10 mm/s actually translates to 100 mm/s etc.). I would greatly appreciate if anyone can lend some insight to this!

    • "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.
