Best 3D Printing Filament & Resin Under £25 in 2026

SUNLU TPU 3D Printer Filament 1.75mm (Black) - £18.99, 4.6★: This filament stands out for its flexibility and speed, making it perfect for creating durable, soft prints. With a dimensional accuracy of +/- 0.03mm, it’s compatible with most FDM printers, ensuring a smooth printing experience. The only downside might be the slightly higher cost compared to other filaments, but the quality is well worth it. Ideal for makers looking to create functional parts or prototypes that require some flex.

SUNLU TPU 3D Printer Filament 1.75mm (Green) - £16.99, 4.6★: Similar to its black counterpart, this filament offers the same high-speed printing capabilities and flexibility. The vibrant green colour adds a fun twist to your prints. The trade-off here is simply the colour choice, but it performs just as well. Great for those who want to add some flair to their flexible prints while maintaining high quality.

OVERTURE TPU Filament 1.75mm (Black) - £17.99, 4.6★: OVERTURE’s TPU filament is another excellent choice for flexible printing. With a slightly better dimensional accuracy of +/- 0.02mm, it offers precision in every print. However, it may not print as quickly as the SUNLU options, which could be a consideration for those prioritising speed. This filament is perfect for users who value accuracy and are willing to spend a little more time on their prints for that extra detail.
