“Orthopedics and maxillofacial surgery are examples of areas where this could be applied.”įirst announced in 2018, Vestakeep i4 3DF is the first PEEK-based filament that can be used for implant applications. “For modern medical technology, the development of our first 3D-printable implant material opens up new opportunities for customizing patient treatments,” said Marc Knebel, who heads the Medical Devices & Systems market segment at Evonik. Having met ASTM F2026 requirements, the industry standard for surgical implant applications, the new material will allow for the production of 3D plastic surgical implants using Fused Filament Fabrication (FFF) technology.

Its other 3D printing materials are used in highly demanding environments, and include resins suitable for photocuring and powders ideal for sintering -based manufacturing processes.Ĭuriveta plans a full commercial launch in the United States later this year. In addition to these implant grade filaments, the company produces a testing-grade PEEK filament that offers the same properties without the documentation needed for surgical implants. “ Innovative developments like our VESTAKEEP® i4 3DF PEEK filaments, are designed for the utmost biocompatibility, biostability and x-ray transparency – making them excellent materials for orthopedic and maxillofacial surgery,” says Marc Knebel, head of Evonik’s Medical Devices & Systems market segment.Įvonik’s products (high-performance polymers and additives) have been used in 3D printing applications for more than 20 years. What is this PEEK filament biomaterial designed for medical 3D printing?ĭesigned especially for use in additive manufacturing processes, Evonik’s VESTAKEEP® i4 3DF comes in filament form and meets stringent requirements of ASTM F2026, which is the standard for PEEK polymers approved for use in surgical implant applications. It also creates an optimal environment for osteoprogenitor cells to move throughout the implant enhancing bone healing (fusion) and reducing risk of subsidence. Since the FDA clearance, surgeons have been able to complete first surgeries with the new product.Īs Kevin Foley, professor of neurosurgery, orthopedic surgery and biomedical engineering at the University of Tennessee Health Science Center, implies, the Inspire porous PEEK technology checks all of the boxes for an ideal interbody implant: fully interconnected porosity, modulus of elasticity equivalent to cancellous bone, strong biomechanical properties, radiolucency, and a bioactive surface for osseointegration.Īdded to these boxes a pore size distribution, and nano-surface architecture, and the implant enhanced with HAFUSE nano-surface topography enables the most effective synthetic allografts. “Structure drives biology and the lattice PEEK architecture enabled by Curiteva’s 3D printing process represents an exciting advancement in spine, orthopedics, and neurosurgical procedures which involve any type of biologic implant“, Alex Vaccaro, MD, PhD, president of Philadelphia-based Rothman Orthopedic Institute shared. Developed in-house using a patented FFF 3D printer designed, programmed, and built by Curiteva, the Inspire platform is manufactured utilizing the Evonik VESTAKEEP® i4 3DF PEEK high-performance polymer. Two months ago, medical technology company Curiveta was granted FDA clearance for a 3D printed PEEK implant, the Inspire Porous PEEK Cervical Interbody System with HA FUSE Technology.
