Filament flow rate calibration hassle?

Bambu Lab P1 Series General Discussions

Hi folks,

Context:
I’m pretty new to 3d printing I bought myself an A1 Mini to learn and play with while a shattered femur kept me out of my home workshop, now I’m hooked! I make mainly small functional parts for automotive and robotics applications. Currently I’m using my printer for prototyping and then getting a friend to print the final parts out of ABS and various nylons. I’d like to print my own final parts so am considering a P1S or a X1C or waiting perhaps for the new flagship…I’m currently spoilt by the A1 minis automatic flow calibration, I just leave the box checked and let it auto calibrate at every print.

Questions, if I get a P1S:

How variable are filament flow rates from the same manufacturer and material roll to roll? Do you have to do a manual calibration exercise new every roll?

Are some materials particularly more variable roll to roll?

How time consuming is the manual calibration exercise?

Any intel or insight gratefully received

Hi there,

I’ve been printing on a handful of P1S printers for a while now, always using the same manufacturer and plastic type. For me, the printers have worked out of the box without a need for even manual calibration. Maybe it’s just luck, but picking the preset filament brand/type seems to work just fine and doesn’t need anything else. Especially not from roll to roll. Hope this helps.

What brands and materials do you usually print?

I use Overture PETG and haven’t had any significant issues, and the Bambu filament that comes with the printer has always worked too.
