Why You Should Use Filament Refills

Why You Should Use Filament Refills

As 3D printing enthusiasts, we’re constantly seeking innovative ways to enhance our printing experience while being mindful of the environment. One impactful solution is transitioning to filament refills, which offer numerous benefits over traditional plastic spools. We’ll explore why using filament refills is a smart choice for the eco-conscious maker. We’ll also explore reusable spools for refills and their contribution to a greener 3D printing journey.

Environmental Sustainability

One of the most compelling reasons to embrace filament refills is their positive impact on the environment. By eliminating the need for plastic spools, we significantly reduce plastic waste in our 3D printing process. Plastic spools take up space in landfills and contribute to pollution, but with refillable filament options, we can play our part in conserving the environment for future generations.

Storage Efficiency

Let’s face it: plastic spools take up a significant amount of storage space. With filament refills, we can eliminate the clutter caused by multiple spools and free up valuable real estate in our workshops or printing stations. This enhanced storage efficiency allows for a more organized and optimized workspace, making our creative process smoother and more enjoyable.

Re-usable Spool for Refills

To further streamline our filament refill experience, eSUN has introduced the innovative eSPOOL Refill Holder. This compact and user-friendly device securely holds filament refills, providing stability and ensuring hassle-free printing sessions. There are also spools you can print yourself.

However, it’s not without its flaws, small flaws but flaws nonetheless. There are limited materials and colours available in the form of refills, usually PLA, ABS and PET-G, which restricts the choice of materials. This isn’t an issue if you use a lot of those materials. The next issue is that it can be a little tricky to re-spool the refill, which also creates the opportunity for tangles to occur. In our opinion, these flaws are vastly outweighed by the benefits as most general users will use one of the main materials available and the refills can be used concurrently with regular spools.

Who Supplies Refills?

We stock a couple of brands that supply a wide range of refills. eSUN has a selection of PLA+ & PET-G which includes a decent but basic selection of colours. Fiberlogy also has a selection of Easy PLA and Easy PET-G with a limited choice of colours. We also stock rPLA from Reflow, a 100% recycled PLA.


As we embark on a journey of sustainable making, embracing filament refills is a logical step for 3D printing enthusiasts. By reducing plastic waste,  optimizing storage space, and leveraging innovative accessories like the eSPOOL Filament Spool Holder from eSUN, we can enhance our printing experience while preserving the environment. Let’s embrace this eco-friendly approach, unleash our creativity, and contribute to a greener future, one print at a time.

    Great idea but actually doesn’t pass the straight face test.
    1 You have to buy at least one eSun reusable spool or every time you want to changes you then have the hassle of loading and unloading filament on to the reusable spool (costs end user more as usual to be environmentally less damaging and eSun are based in the Far East)
    2 Despite not using the plastic spools for new filament the replacement filament without a spool is the same cost (no cost advantage for being less environmentally damaging)
    3 Limited colour range (another downside to being less environmentally damaging)
    4 I always worry about a plastic snap fit connectors lasting multiple uses after being exposed to heat (dehumidifying) and light. The end user take the risk of solution failing.

    I will keep looking out being less environmentally damaging and the fact that eSun are now shipping cardboard spools rather than plastic makes the process less damaging anyway. I keep looking at UK supply of filament so that the production process (green energy) and shortened supply chain (UK production and distribution) probably has a bigger environmental impact than reuseable spools. Perhaps UK produced filament as free samples might be a better way of pushing environmental considerations and encouraging a less damaging approach.

    Keep being a great filament supplier. Other than the delivery company changing, I’m glad to see that your recent warehouse and logistics changes made no difference to the excellent service you have provided me since I started 3D printing. Hope you had a great Christmas and have a fantastic 2024.

      Hi Robert,

      You make some good points, FYI the article was written before eSUN were fully adopting cardboard spools and we did mention the issues of limited colours and the inconvenience of changing the filament on the spool in the article.

      There is no price difference as there is no price difference for us as resellers.

      Indeed, there is an impact of the spools being shipped from China, however we do try to mitigate this by receiving a large amount at a time as to reduce costs and frequency of deliveries.

      As for UK suppliers, we have recently introduced 3DQF, which are low-cost and on cardboard spools. We will be expanding the colour range in the new year.

      Thank you for your kind feedback regarding our service, your valued custom and for joining the discussion. We’ll look into updating our article.

      From all of us at 3DFilaPrint, we wish you a happy new year.

      Kind regards,
