Topic: What speed, what risks ?

Hi,

  I'm currently printing at 60mm/s (settings from solidoodle.blogspot.fr or the default ones if I remember well).
  I was wondering what are the risks of increasing those values (except for the quality of the details).
  Is there a risk for the mecanical parts (belt, motors, acrilic extruder), for the filament (more tension, more breaks), or other ?
  Will the produced part be more fragile (internally) ? Should I take care not to have to small gaps to infill (to avoid excessive vibrations) or is there a "max vibration" protection of some sort ?
  I've seen is this forum people taking about 500mm/s. Is this a regular and safe speed for prototyping ?

Regards,

Re: What speed, what risks ?

I would suggest you increase any of those numbers in increments of 10 and see the corresponding affect.  You aren't going to break anything at any speeds that would still yield a usable print.  Remember that as speed increases you may need to increase the temperature.  If your using a stock hot end then that is going to be your limiting factor.  If you are running an all metal hot end then you should be able to run 100 mm/s and still get close to the same quality as your getting now.  I run most of my prints about 150 mm/s and some faster or slower depending on the part I'm going to print.
Have fun with it you' learn a lot about your printer and what needs to be tweaked and adjusted.  Also higher speeds will call to attention calibration flaws real quick.
