“…The high ratio of carbon content (83.5%) in PEKK material is crucial, particularly when compared to materials like PET-G (having 65% ratio of carbon content) and MED 857 (DraftWhite) (having approximate 30% ratio of carbon content), as it confers a suite of enhanced properties (Baek et al, 2022;Gabalski et al, 2023;Kulkarni and Narayan, 2023). Carbon atoms, that are integral to the polymer matrix, contribute significantly to the overall stability and strength of material.…”

Advancements in materials science and 3D printing technologies have opened up new avenues for developing low-cost robotic grippers with high-performance capabilities, making them suitable for various biomechatronic applications. In this research, it has been explored the utilization of high-performance polymer materials, such as Polyetherketoneketone (PEKK), Polyethylene Terephthalate Glycol (PET-G) and MED 857 (DraftWhite), in the designing and developing of customized robotic grippers. The primary focus of made analyses was oriented on materials characterization, both experimentally and analytically. Computer-Aided Engineering (CAE) methods were employed to simulate bending experiments, allowing for a comprehensive analysis of the mechanical behavior of the selected materials. These simulations were validated through physical bending experiments using samples fabricated via 3D printing technologies, including Fused Filament Fabrication (FFF) for PET-G and PEKK, as well as Jetted Photopolymer (PolyJet) technology employing UV Resin for MED 857. The findings of this research provided advantages of utilizing advanced materials like PEKK in low-cost robotic grippers for biomechatronic applications. The experimental and analytical approaches offer valuable insights into material selection, design optimization, and the development of cost-effective high-performing robotic systems with a wide range of applications in the field of biomechatronics.

We examined the impact of 3D-printing parameters, such as the deposition pattern, deposition speed, and layer height, on the tribological performance measured through the coefficient of friction and cumulative linear wear. Optimizing these factors can significantly influence material wear and friction, which is critical for ensuring durability and functionality in practical applications like a cylindrical gear assembly for a vertical-articulated robot. The purpose of the study was to investigate these relationships by employing the Box–Behnken design (BBD) method to systematically analyze the effects of these parameters, while also using scanning electron microscopy (SEM) for detailed microstructural characterization. The findings aim to provide insights that can guide the development of more efficient and wear-resistant 3D-printed materials. The strong impact of layer height on CLW was noted, showing that lower layer heights can either improve or worsen wear depending on the combination of speed and pattern, with layer height playing a dominant role in determining wear performance. Lower speeds and specific patterns, particularly lines and concentric patterns, tend to result in higher COF values. The validation test results, with a COF of 0.2215 and CLW of 29.2075, closely align with the predicted values of 0.2064 and 27.3, showing small percentage errors of 7.3% for COF and 6.5% for CLW.
