5 Alternatives to the SUNLU TPU Filament (Including 2 That Are Better)

If you’re set on the SUNLU brand but can’t find the green filament, this high-speed black TPU is an excellent substitute. It shares the same 95A hardness and dimensional accuracy of +/- 0.03mm, making it a reliable choice for flexible prints. The only downside is the slight price increase, but if you're after a classic black finish, this is a solid option. Perfect for users who want the reliability of SUNLU with a different aesthetic.

OVERTURE’s TPU filament is another fantastic alternative. With a slightly tighter dimensional accuracy of +/- 0.02mm, it promises even better consistency in your prints. Users have reported excellent layer adhesion and flexibility, making it a great choice for functional parts. The only consideration is that it may require a bit more fine-tuning in your slicer settings compared to SUNLU. Ideal for those who are focused on precision and performance in their flexible prints.

eSUN’s eTPU is well-regarded in the community for its outstanding print qualities and flexibility. It offers a shore hardness rating of 90A, which provides a bit more softness compared to SUNLU’s 95A, perfect for applications requiring extra elasticity. The downside? The price is a tad higher, and it may not be as fast to print as the SUNLU variant. This is an excellent choice for those prioritising flexibility, especially for wearable items or soft grips.

This vibrant orange TPU from SainSmart is a great budget-friendly alternative. It has similar flexibility and performance to SUNLU, though some users have noted that it can be a bit more challenging with bed adhesion. However, it’s a fantastic option for those looking to add a pop of colour to their projects without breaking the bank. Suitable for hobbyists or anyone new to flexible materials who wants to experiment.

If you’re after premium quality, MatterHackers offers a PRO Series TPU that’s incredibly well-reviewed for its consistent results and ease of printing. With a shore hardness of 95A, it matches SUNLU in feel but often surpasses it in print reliability. The only downside is the higher price tag, making it less appealing for budget-conscious makers. Perfect for those who want the best and are willing to invest in their filament for top-notch results.
