“…38 MPa and yield of 29.34 MPa and bound of elasticity of 0056 to 0044, substantial and modulus value at 38%, average compression modulus value adjusted to 1.82 GPa for stable PEEK close to the amounts reported in the literature for similar compressive conditions 7 MPa[35][36][37][38]. PEEK samples, printed in 3D with a porosity of 14% and 31%, have a lower resistance to stress compared to Ultem 9085 and PEEK injection moulded.…”

“…Physical form is more related to the natural organisation of cells in nature and allows better orientation of the orientation and fixation of the cell [11,12]. Due to the different types of free extrusion, AM technology has been identified as the most efficient way to make fabrics such as porous scaffolds of Tissue Engineering with porous three-dimensional structures capable of handling various materials like ceramics, cells Superior and thermoplastics are reproducibilities, excellent control over macro/microarchitecture and critically low cost [13,14]. Also similar to this method can also be used to print out non-skeletal three-dimensional structures.…”

Research and development on PEEK composites with high thermal conductivities and ideal thermal stabilities have become one of the hot topics in composites. However, not all PEEK composites have the necessary characteristics adequate fracture toughness to resist forces and crack propagation, with an improved mechanical and structural properties. This research evaluates a novel computational surface characterisation, and Finite Element Analysis (FEA) of polyetheretherketone and hydroxyapatite Graphene oxide (PEEK-HAP-GO) in the process of 3D printing to improve fracture toughness to resist forces and crack propagation. It also focuses on increasing the hydrophilicity, surface roughness, and coating osteoconductive of PEEK-HAP-GO for the bone implant. Compression and tensile tests were performed to investigate the mechanical properties of the PEEK-HAP-GO structure. The addition of calcium phosphate and the incorporation of porosity in PEEK-HAP-GO has been identified as an effective way to improve the osseointegration of bone-implant interfaces of PEEK-HAP-GO. The further analytical structure of the particle was performed, evaluating the surface luminance structure and the profile structure of composite material in 3D printing, analysing the profile curve of the nanostructure from the scanning electron microscope (SEM). The results of the uniaxial compression tests in new PEEK-HAP-GO biodegradable materials show good compressive strength suitable for loading applications. It shows Melt-blending with bioactive nanoparticles can be used to produce bioactive nanocomposites like HAP-GO and is used to modify the surface structure of PEEK implants in order to make it more bioactive.

“…PEEK is suitable for orthopedic implants, which are in direct contact with the bone. It is considered as an alternative material in total hip arthroplasty, to avoid metal-metal debris and to minimize the risk of particle-induced aseptic implant loosening [ 22 , 23 ]. In hand and wrist surgery, PEEK-related complications, such as foreign body synovitis, can occur in a total wrist arthroplasty because of the shearing forces on the implant [ 24 ].…”

“…A rough surface inside the channel could lead to a better connection between the tendon and the PEEK surface. The well-known osseointegration abilities of PEEK into the bone might also contribute to the adhesion between the tendon and the PEEK surface [ 23 , 26 – 28 ].…”

Recently, three-dimensional (3D) printing has become increasingly popular in the medical sector for the production of anatomical biomodels, surgical guides, and prosthetics. With the availability of low-cost desktop 3D printers and affordable materials, the in-house or point-of-care manufacturing of biomodels and Class II medical devices has gained considerable attention in personalized medicine. Another projected development in medical 3D printing for personalized treatment is the in-house production of patient-specific implants (PSIs) for partial and total bone replacements made of medical-grade material such as polyetheretherketone (PEEK). We present the first in-hospital 3D printed scaphoid prosthesis using medical-grade PEEK with fused filament fabrication (FFF) 3D printing technology.
