Filament Brands for P1S and AMS

Bambu Lab P Series
1

Hi,

I am new and so far I have only used Bambu Labs branded filament which with the membership prices is very good but I want to do some rainbow prints so I was wondering what brands to look for or which brands to avoid?

  1. Tolerance needs to be +/- 0.05mm or less?

  2. What printing speed to I need to look for?

  3. I’m guessing eSUN are good as I see them mentioned everywhere
    and random sounding names on ebay/amazon probably best avoided?

Thanks

Keep the acceptable tolerance below .03 because of the PTFE tubes and their necessity, otherwise skys the limit, just remember not all brands are created equally and not all reviews are real, also stay away from glitter filaments without changing to a .6 nozzle, otherwise it clogs and can make for a very bad day

Ok I’ll make a note of the 0.03 and I think I read that for some rainbow or glow in the dark filament a hardened steel nozzle is required.

I’ve just been browsing eSUN and SUNLU PLA and they generally say

  • Printing Speed：30~90mm/s
  • Movement Speed ：90~150mm/s

Which is a lot lower than the standard settings for a BL printer, so do you slow it down or can the filament handle the higher BL speeds?

The PTFE-Tubes are 2mm. A tolerence of 0.05 IS still ok. Most Manufacturer get it down to 0.03mm or lower.
I Had No problems with 0,05mm with the P1S. And AMS

I ignore the speed-settings they post.
Do pressure advance anf flow calibration.

That should be enough.

But you will. It could be that you think you’ve navigated a +/-.05 bump and probably have not.

  1. With the wide PTFE tubes, tolerance is primarily important in the nozzle (unless you have lot of bends in the tube or have lengthened it). Imagine calibrating when the filament is at one extreme and during printing it moves to the other extreme. It can get you straight into under-/over-extrusion troubleshooting hell. Haven’t had that for years though as manufacturers tightened their tolerances.
  2. The Bambu settings for Generic filaments worked quite well for me. I only lowered the max flow rate initially to err on the side of caution.
    For the Fiberlogy BVOH I am using, I stuck to the manufacturers recommendations (lowest temp range though due to stringing).
  3. eSun and Sunlu worked flawless for me. As did Geetech.
