It might be worth it for you to check out some local 3D printing shops in your city/region. If you can find one, it’s better to get filament through them as they will (most of the time) have tested the filaments. Also it might be cheaper than paying for shipping and faster too.
Finally, try samples before you buy more than 1kg of any filament. Not all PLA/ABS filament is the same, different suppliers use different blends (additives) which may change the quality and behavior of the filament and may not work very well on your printer.
I’ve been using OrbPolymer and FormFutura recently on both my Prusa i3 MK2 and my Lulzbot Mini and TAZ6 and really, really like the stuff. More specifically the PLA and PETG from Orb and the Apollox and TitanX from FF.
I use Meltink3d filaments for ABS and PLA. I’ve always gotten quality prints from their stuff, in addition you can buy 90% of what they have from Amazon.
Hi…MELCA is making a name for itself, but perhaps my favorite feature is the amazing customer service. Perhaps it’s because they have so few reviews that when they do get a bad review they can respond so quickly. It just goes to show, if you put out a high-quality product you can take the time to make each customer happy.
As for positive reviews, customers are quite happy with MELCA’s price and quality. This filament boasts excellent tolerances and is known to print well even in inexpensive printers where you would expect to see more problems.
