What brand of filament do you trust that is not sunlu (no navy blue)

Inland, the microcenter house brand, is surprisingly good for the price point and comes in basically every color imaginable.

Polymaker is also very good with lots of colors. They used to be very expensive but the price is competitive today.

@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

Never had any issues with Hatchbox, it's my favorite PLA. I'll use Overture if I want something cheaper that works. Prusament if I want to spend an arm and a leg for shipping. I usually only order Prusament if I need something else from Prusa.

• 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

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.

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

Anything by Spectrum, but especially their Caribbean blue PLA.

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

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.

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!

@terabyterex So far, I've had good experience with Polymaker's Panchroma line and Deeplee (which is an Elegoo brand).

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.

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.
