Hi there, I recently bought a FlashForge finder to print random things I have designed in Autocad, my problem is, is I don’t know how long I can safely print without damaging the stepper motors or extruder, any help and knowledge would be much appreciated. My longest print so far has been four hours, but I have one that would go up to ten hours, I just wasn’t sure if it could handle that.



Printers are generally able to run up to a couple days for a print, my longest print has been 16 hours so far. I think you’ll run into issues with bed adhesion way before you have any problems with the printer itself.

Hope this helps!


I have printed for 46 hours once

and reg. do 12+ print while i sleep


3D printers can work for days.

The problems witch can occur:

- Steppers motor or its drivers get too hot and will lose steps= lower the motor current on the drivers, also make sure the stepper drivers have heat sink and a small fan cools the electronics

- Print head jams : use a good quality filament and a quality hotend like E3D V6

- Print peels of the build plate during print, use brim or raft for long prints for best adhesion. Make sure the print surface is super clean before print starts or use glue stick/hairspray, also a correct bed leveling is a key point for best first layer adhesion to the print bed.

I have done a print that took 60 hours and it was working perfectly until the power flickered a 99% which killed the print, but yeah once it starts printing as long as it doesn’t Jam you can just leave it alone and monitor the filament.
