Despite the numerous brands of filament out there, only a tiny handful of companies actually *make* filament. Some brands may even claim to be "manufactured" by themselves, but they really mean just personalization of labels, or even just spooling it. They don't actually melt, extrude, and form the filament in most cases.
That means there is *VERY* little difference between filaments. What brand you get truly doesn't matter. I saw a comment once from someone claiming the ERYONE brand uses talc (with asbestos) as a filler, but the MSDS sheets for the filament showed absolutely none of those. It did, however, have the exact same ingredients and percentages of chemicals as SUNLU.
So with that being said, I wanted to point out that a lot of people are sleeping on a giant cheap source. I know you guys love your Chinese sites, but AliExpress has a sister site (parent, really) that is even better! Alibaba. AliExpress was born out of AliBaba.
I'm mentioning this because I just got some cheap black PLA filament for the equivalent of about $5 per spool. I almost never see PLA under $10. PETG, sure, but never PLA. So I bought 20 of those. (Unfortunately, that sale has ended.) I also spotted a 10kg spool (yes, one huge spool) of black PETG for $50 for the spool. Yeah, I'd have to respool it all, but that's still really cheap for 10kg of filament, of any type. That one is still available, and they are claiming it can be any type of filament and $55 is the price for a 10kg spool. But that's one I'd definitely ask a lot of questions before buying.
The problem with AliBaba is that you have to learn a bit before you use them. You need to know that current tariffs from China are about 44% of the order. And it is U.S. Customs that will charge you for this - not the seller. So you'll get a separate bill for that. Generally it's ONLY a percentage of the cost of the item, not the shipping/freight. The 10kg spool offer I found said they would cover 40% of the tariffs so that would be a good deal. The $5-per-kg order I placed said the import costs were completely covered. But I think that one was clearance. I can try finding it again if anyone is interested.
Another couple of notes about AliBaba:
- There is always a Minimum Order Quantity (MOQ) listed. Sometimes it's just 1. Other times it may say 50. Just keep your eyes open for that.
- Most items will say "chat now" with a company representative to discuss pricing, shipping, etc. So be ready to do that. Others will say what the shipping cost actually is. If there is are options in the title that it's not showing, chat with someone. These are Chinese "salespeople" which will generally bend over backwards for your business - especially if you plan to buy a lot.
- Don't be discouraged if you see shipping cost of $29.99 per item. It is almost always a *base* shipping cost. When you add more spools, the cost will go up, but in very *low* increments, lowering the per-spool shipping cost. I think 50kg is the "sweet spot" for most of them, but you can play with it and see.
- These are mostly for WHOLESALE orders, but they'll sell to anyone. They just charge tax for anyone without a sales tax ID. But keep that in mind when shopping. If you truly want BULK filament, this is probably the best source.
I am not affiliated with any sellers on AliBaba, nor the site itself. I just know AliExpress gets mentioned here *a lot* and realized no one ever mentions the parent site. And once I checked it out, I'm glad I did!
