Best 3D Printing Filament & Resin Under £50 in 2026

SUNLU TPU 3D Printer Filament 1.75mm (Black) - £18.99, 4.6★: This filament is a standout for its high-speed printing capabilities and flexibility, making it ideal for creating durable, rubber-like parts. With a dimensional accuracy of +/- 0.03mm, it ensures precision in your prints. The only downside might be the slightly steeper learning curve for beginners, but it's perfect for those looking to experiment with flexible materials. 2. SUNLU TPU 3D Printer Filament 1.75mm (Green) - £16.99, 4.6★: Similar to its black counterpart, this green variant offers the same high-speed and flexible printing benefits. The vibrant colour adds a fun twist to your projects, making it great for decorative items or prototypes. The trade-off is that both SUNLU filaments can require fine-tuning of your printer settings for optimal results, but once dialled in, they perform exceptionally well. 3. OVERTURE TPU Filament 1.75mm (Black) - £17.99, 4.6★: OVERTURE's TPU filament is another excellent choice, boasting a slightly tighter dimensional accuracy of +/- 0.02mm. This makes it a reliable option for detailed prints. The flexibility is on par with the SUNLU offerings, but some users report a slightly stiffer feel. This filament is best for makers who want a balance between flexibility and detail, although it may need a little more attention to bed adhesion compared to the others.
