The Hidden Cost of "Empty Spool Clutter"
Traditional filament creates unnecessary waste and costs you money
Plastic Waste
220g of plastic dumped per traditional spool – that’s 11kg per year for the average maker
Higher Costs
The spools cost money and you just end up throwing them away anyway.
Workspace Clutter
Bulky empty spools stealing valuable space in your workshop

Frequently Asked Questions
Everything you need to know about switching to PCTG refills
Is PCTG more difficult to print than PETG?
Not at all. PCTG prints similarly to PETG but with slightly higher temperature and less stringing. It’s designed to be easy to print on most FDM machines without a closed chamber.
How does it compare to PETG?
PCTG offers improved impact toughness, better chemical resistance, and greater clarity. It’s ideal for parts that require higher durability or exposure to mechanical or chemical stress.
Can I use my existing reusable spools?
Yes. Our refill coils are compatible with most reusable spools, including Bambu Lab spools. You can also use our precision-engineered 3DTrcek reusable spools for the easiest, fastest loading.
Is it compatible with the Bambu Lab AMS?
Absolutely! 3DTrcek PCTG Refill Filament is AMS-ready and used by hundreds of Bambu Lab users. Stable winding and consistent diameter ensure smooth feeding in multi-spool setups.
What are the key benefits of PCTG Refill?
✅ Stronger and tougher than PETG
✅ Chemical-resistant and temperature-stable
✅ Eco-friendly and refill-based – less waste, lower cost
