Recommendations for a good grippy / tacky TPU? I’m printing replacement treads for my robotic vacuum and the TPU I have is not really that grippy on hard wood floors.
Ninjaflex is pretty tacky. Any TPU/TPE between 60-70A will be pretty soft. Ninjatech has some new chinchilla material that could work
Looking for the same… I have used the following TPUs and none of the following are grippy or tacky on hard and smooth surfaces. The softer ones will grip a bit better than harder ones on textured or coarse surfaces, but not even close to a rubber.
- 3dFils 60D, 90A, 85A (Spanish brand, prints well, some thickness fluctuations. i.e. not for tight tolerances, available in smaller spools, decent price)
- AzureFilm 85A, 98A (Slovenian brand, prints easily, even quality, nice finish, available in smaller spools, decent price)
- 3DPrima EasyPrint 95A (Swedish brand, prints easily, even at lower temps, good finish, quite expensive, samples available)
- 3DPrima PrimaSelect 45D (prints well, requires higher temps, more expensive, good finish, expensive, samples available)
- Fillamentum 98A (Czech brand, a good quality filament, lower elongation=thick walls makes objects stiffer than with other filaments, expensive)
- DevilDesign 55D (Polish brand, prints well, similar stiffness to Fillamentum above, average price but only available in 1 kg spools)
- PrintMe 20D (Polish brand, very flexible, prints OKish, available in smaller spools, quite expensive)
Of these, the PrintMe 20D is the least slippy, but I would not call it no where near greippy or tacky.
