So, you’re getting caught up with your 3D printer filament supply, huh? Have you thought about buying bulk PLA filament to make it more convenient for you? Luckily, in this post, we listed down and reviewed 5 of the best bulk PLA filament suppliers for you.
Is it Time to Buy PLA Filament in Bulk?
If you’re working on big projects or you have a 3D printing business, then it might be time for you to buy PLA spools in bulk. Purchasing 1.75mm PLA filaments with more than 1 KG per spool can possibly be cheaper than buying 10 or 15 spools of filaments. That is if you find the right supplier.
Now, there are a number of suppliers out there who are happy to offer you 3kg, 4kg, 5kg, or even up to 15 kg of PLA per spool. Don’t be afraid to try on these extra-large filament reels because it would probably be worth it in terms of price.
However, if it’s a new brand you weren’t able to try on before, this may present you with some drawbacks. The most obvious one being you not knowing how the new brand will work on your printer.
To help you decide if it’s time to buy PLA filaments in bulk, here are a few things to think about first.
1. Do you have a 3D printing business where you can benefit from bulk filament spools?
If you’re running a 3D printing business, it’s pretty obvious that purchasing large PLA filament spools is economic on your end. After all, running such a business requires a lot of 3D printing, testing, and prototyping.
Perhaps 1KG of PLA spool quickly runs out during the day! Of course, this depends on how big your nozzle is, the printing speed, and the number of customers you have. But the point is, if your filament changeover is pretty fast, then you can save a lot of operation costs if you buy in bulk reels.
If you’re not sure about the quality of the supplier, you can ask for free samples. Some suppliers offer test kits with a variety of filament samples for free or a few bucks.
If you’re printing large volume objects or you’ve got your hands full on projects, you might be using more than just 1KG spool of filament a day. For example, props and bigger projects can take up to 5 to 10kg of filament. This means using a lot of 1KG rolls might not be the best thing to do as you would constantly need to change filament rolls.
3. Do you prefer a specific brand of PLA filament for 3D printing your projects?
Buying a large filament roll can only be economic if you’ve already tested and liked a specific brand. But what if you’ve not tried a new brand, bought a large spool, and found it unsatisfactory? This is a pretty bad investment.
Before you purchase bulk PLA filaments, make sure you’re already satisfied with the product. Try out its sample filaments first or buy a 1KG spool from that manufacturer. When you’ve checked its quality and consistency, then buying a bulk spool is good to go.
Another thing you should absolutely consider is how you can store your leftover filament. If you buy a lot of filaments and you don’t have a proper storage compartment, it may become brittle, wet, and have a weak layer adhesion. Standard PLA should be stored in areas with humidities of 30- 50%.
If you haven’t planned on how to keep your filaments dry, then it’s time for you to do so before you even buy bulk PLA filaments.

Advantages & Disadvantages of Buying PLA Filament in Bulk
Pros
1. Convenience
You don’t need to constantly order or restock filaments.
2. Economic
Bulk 3D printer filaments cost way cheaper per gram than 1KG rolls of filaments.
3. Speed
Each time you run out of filaments from each roll, you constantly need to stop the printer, clean the nozzle and tune the printer to feed the new filament. With bulk filament rolls, you cut out 50% of your time doing these tasks leading to speedier operations.
4. Consistent 3D Prints
Whenever you change a filament spool, you might have issues regarding consistent 3D prints. With a huge spool, you won’t need to worry about having inconsistent and quality issues. This is a very important consideration especially if you’re running a business where you need to constantly quality check your products being consistent.
Cons
1. Keeping the Filament Dry
As we’ve said earlier, this is one of the major issues you’ll face when using large filament rolls. Keeping the filament dry by properly storing them is trickier when you’re handling larger filaments as it has more volume than its smaller counterparts.
Wrapping Up
If you’re 3D printing more often than before or if you have a small business that requires you to 3D print a lot of items, then it might be time to buy bulk PLA filaments. Purchasing bulk filaments alone is a major investment. That’s why you need to ensure the quality, consistency, affordability, and reliability of your supplier.
We hope you’re able to find the best PLA filament supplier and ways to handle, use and store your bulk filaments through this article.
