 Poly-33 ketone, peak, has been identified as a promising material for 3D printing due to its excellent mechanical properties. In this study, it was shown that peak exited superior mechanical properties compared to acrylonitrobutadiene styrene, ABS. Specifically, peak had higher tensile, compressive and bending strengths, while maintaining similar modulus of elasticity. Additionally, peak had better printing performance than ABS, with higher tensile strengths of up to 108%, suggesting that peak may be a viable alternative to ABS for 3D printing applications.
