Review on 🖨️ ESUN 1.75mm Printer Filament Refills: Premium Quality for Uninterrupted Printing by Jonathan Fernandez

7/15/2027 Update: I still love eSun PLA+ Filament and have used many hundreds more spools since I wrote the original review below. I no longer rewind it on my own printed masterpools because the reels which come in 4 reels each lately are working fine. I've had a few breaks disassembling so I'm glad they send new ones in every package. I've never had any problems with the thread itself. I print it at 210-220°C on my small printers and 220-230°C on my CoreXY machines, pushing 25cm^3/s through a 0.6mm nozzle and it works great. Hundreds of roles I've used. Anyway, I've rewound every thread I've bought in the last 10 months, so I don't mind doing it with them to get a *much* better price on my favorite thread. The 4 pens were packaged in individually wrapped plastic bags in a nice box that I can probably reuse. I hope they will make them available in multiple packs of the same color in the near future! One star deducted for not fitting my master spools (eSun screw-in spools are much more difficult to work with than real master spools), but as I said, the filament itself is fantastic! 2823667) along with a hub (Item: 3140616) scaled to 105% XY and 95% Z with a winder to create my own interchangeable spools so they can be easily snapped on and off from printed versions of the same parts at 100% Size for use on all my printers.
