@terabyterex poly maker pla is my go to.

I've honestly only had one bad roll ever.

I've bought a ton of cheap 3djhor filament with no issues.

I've tried at least 20 brands.

I can say my ender was way more finicky than my Bambu is. The Bambu rarely has issues even with filament my ender struggled with.

Also the only filament I have had to be choosey with is silks.

And brand is just one factor. I've had good rolls of one color from a brand and not so great of a different color. Same brand.

Basically poor overhangs. But otherwise they all print well. Just some do worse on overhangs.

Maybe fixed by slowing the print speed down but not usually a big deal on whatever I was printing.

What kind of printer do you have ?

The ones I've come to really like for their consistent quality results are:

• Prusament (PETG)
• Fiberlogy (ASA) <-- I'm sure i have a navy blue spool from them in my print room. I'd double check, but it's way past my bed time
• eSun (ABS)
• Addnorth (Various)

For PLA, any brand that has the blue you seek. PLA is not that complicated.

Prusament. Stopped getting anything else, unless I need something super specific that they don't have

Before my last printer died 5 years ago, I was getting good results with Hatchbox filament. Not sure about their current state, but they were the most reliable I had found at that time. Looks like they currently have one I would call navy blue.

My new printer is supposed to arrive today, so I'll be going through the filament evaluation grind again soon.

• Prusament: always top quality, at a price (PLA, PETG and ASA)
• dasfilament.de: I bought a few spools and it has been good so far (PLA and PETG)

Edit: forgot to mention Colorfabb, I used a lot of their Economy PETG, it's fine in terms of quality, not as good as Prusament. Nowadays the price isn't that good compared to competition.

Don't have a lot of choices here in NZ, esun is a decent quality cheap option we can get in store. Otherwise it's Bambu which can be variable, some print great and some are a nightmare. Or a limited selection of prusament at a big markup over buying it directly

I love Hatchbox. They have excellent filaments and rich colors. Can't say enough love of them. particularly like their matte ones. They were really easy to dial in to perfect.

I use PolyTerra Army Blue for all my Navy Blue needs. Technically it's a matte filament but I honestly can't tell.

Edit: PolyTerra (made by Polymaker) is now called "Panchroma matte" for some terrible reason

Late to the game,but imho best navy blue is black forest Filaments Navy Blue - but of course these are hard to get outside of Europe.

Anything by Spectrum, but especially their Caribbean blue PLA.

I tend to stick Elegoo PLA/PLA+ and that usually works well for me - their dark blue looks fantastic IMO. Overture's PLA seems to print well too, so did the roll of eSun I got.

Just avoid Creality Ender PLA at all costs. That stuff was awful!

I pretty much only use prusament. Literally today I bought some overture for the first time. Read a bunch of posts and decided to give it a try.

@terabyterex I use Elegoo PLA+ or ASA+ (I have Elegoo printers)
