Hello, I am not completely sure how the forums work but I have an Ultimaker Original with a heated bed and wanted to know if anyone had any suggestions on how to increase print speed while also keep relatively good print quality. Anything helps, thanks in advance!

    It all is a question of balance... And that depends on the end use of your prints.

    I have 2 UMO that I have modified, I almost always print at 40-50 mm/min because for me dimensional precision is the most important, I print parts that have to mount together so tolerances are important.

     

    The basics for quality is to put all speeds at the same (outer and inner wall, infill etc...) and for the first layer I put it at 1/2 of the "normal" print speed. Don't put Jerk to high, jerk is the first acceleration, for example if your printer is stopped and starts a print at 60 mm/s it will jump from 0 to the jerk value instantaneously. I typically use a jerk value of 20.

    After that it will use the defined acceleration value to go up to the requested  speed, you can push up your acceleration a little bit, but I never tried that so I can't give you advise.

     

    The best for you is to define a test print (for example a Benchy) and try to play around with the values to see the differences in quality and print speed. Keep note of which sample has been printed with which settings. It is time and material consuming but It will give you precious knowledge about your machine.
