I use three regularly: Polyterra PLA for low cost filaments, Polylite PLA Pro for my fastest prints or prints needing a little strength, and Polylite ASA for anything functional, for outdoors, or for high temp. The ASA surprised me with how easy it's been to print. I've printed with 3DBestX ASA I think, and it's OK, but not nearly as easy as the Polylite ASA. I bought a roll of ApolloX ASA recently but haven't tried it yet.

If I need PETG, ESUN PETG prints the easiest, I've found. Not as easy as ASA (I have a heated chamber), but it's the least aggravating PETG. ESUN PLA+ prints great, but is a bit more shiny than the Polylite PLA Pro, so it's a personal preference. The ESUN PLA+ has slightly higher temperatures and I've had one print failure recently from poor layer adhesion when I was pushing it as hard as I could with print speed.

For my Monoprice mini select with a V6 hot end, I use whatever PLA is on sale. Right now Amazon Basics silk PLA, and two rolls of elegoo PLA. I rarely print high demand parts with the Monoprice. Right now it's only printing 18650 holders for a cell balancer I'm building.

Yeah, "cheap" filament is largely good quality now, and only the unbranded Chinese-made stuff is actually "cheap."

I also really like Inland (Microcenter) because they use good manufacturers. Esun makes their PLA/+ and Polymaker manufacturers their ASA. I will also buy directly from both of those companies because of my exposure to them via Microcenter's house brand.

I'm also a big fan of Atomic Filament and Overture and Prusament. Atomic and Prusament can be pricey, but man are they some of the very best I've used.

Polymaker polyterra. I especially love their army blue and black filament. They print nice and matte, and the colors print almost identical between their different colors. I always thought polymaker was a more expensive brand, but polyterra hits that 20usd/kg for pla price point that hatchbox and other budget filaments used to dominate

Hatchbox has been my primary brand in the 5 years I've been printing - I've had great success with their PLA, ABS, and PETG.

PolyTerra Matte

I love prusament filaments but with shipping and duties I don't keep them stocked. I'm not sure who supplies it but I've had solid results out of spool3d.ca abs and petg filament, also really like Canada Filament's carbon capture PETG, stocking up on more of that and the carbon capture pla. Had really nice results out of Worday ABS as well.

I switched to Atomic over 4 years ago and it's the only brand I buy now. I don't like wasting plastic and I know Atomic will print perfectly for me. If there's an issue, it was my printer's fault.

eSun PLA+. It's easy to print, looks great, and is decently strong for most uses.

I switched to Printed Solid Jessie filaments after my previous bread and butter supplier, 3D Solutech, went out of business. Jessie is been good so far for a relatively low price. I hope they continue to expand their color lineup because they're still missing a lot of shades I used previously. I'm still searching for a secondary brand to fill those gaps.

Getting most of my filament from DasFilament because they are a local (German) company and offer masterspool refills. They "only" sell PLA, PETG and TPU, but so far I haven't messed with other types yet, so that's OK.

My custom blend of SLA-resin has a matt surface with dark metallic color. Also, my most hated filament as it requires a deep clean between prints. FDM? FormFutura SBC: Gave me headaches but that's noticeably higher transmission compared to other "transparent" filaments.

I have Hatchbox PLA in most colors and it works fine for me. If I want to make something more rugged I use eSun PLA+. I also have a couple spools of Tecsonar multicolor PLA filament and those prints always come out looking great!

Most of my PLA is Printed Solid Jesse. It's $20/kg filament that prints like $30/kg filament.

I've been using Jupiter PLA for most prints. I try to use PLA whenever possible because of the lower environmental impact.

It's the cheapest brand available where I live.

I use filaments.ca's house brands, mostly. The price is pretty competitive if you're in Canada, and the quality's been good so far.

I’ve been really liking kingroon lately

Prusament PC for anything functional. I just use Matter Hackers cheap PLA for everything else. They are close enough to me that I get all orders the next day for free.

My current go-to is printbed PLA.

I use Copymaster3D PLA most of the time. It's cheap and locally made. It's not the best (some colours have some inconsistency issues and white PLA has some crap inside), but it works for prototyping and is very dimensionally stable. I also use their Tough PLA for final parts, it's more expensive, bit it's very consistent and prints nicely at higher speeds. Actually it's main issue is that it's too leaky so you can't print it slow - it just sips on its own.

I've had a lot of luck with eSun.

For all the terrain printing I've done over the past 3 years, I've stuck to plain Overture PLA. In the Prusa printers I use, they've been the most reliable with almost no stringing.

Whatever is cheapest on Amazon. I rarely get a bum roll. Although I did 2x in the last couple of years. Both petg wound too hot I think. It was like a brick of petg in the center.

cheapest bottom of the barrel pla, works well enough, and if it doesn't atleast it only costs 11 ish $ per kilo
