Croom Medical, a company known for pushing the adoption of tantalum 3D printing across the healthcare and medical industries, launches a new solution: Biofuse™, a 3D printed porous ingrowth technology for orthopedic implants.
This solution aims to address the limited porosity enabled by traditional surface treatments, such as spray coating or laser texturing. To do so, Biofuse creates porous structures directly during the build, across both surface and sub-surface regions, eliminating delamination risks, removing the need for coating or machining, and ensuring structural integrity with consistent quality.
Manufactured using L-PBF additive technology, Biofuse™ allows OEMs to design custom lattice structures, fully compliant with ASTM F1854. This solution would ensure ‘precise control’ over pore size, porosity, and lattice gradients by integrating fully interconnected porous architectures directly into implant geometries.
“Biofuse draws on our additive experience, where we’ve seen firsthand how components can be both faster and more cost‑effective to print than to machine,” said Sean McConnell, Engineering & NPI Manager at Croom Medical. “Embedding lattice structures directly into the build removes coating and machining steps. The result is a more predictable manufacturing process that consolidates production, preserves structural integrity, and helps OEMs bring implants to market faster.”
As anticipated, thanks to AM, OEMs can achieve complex geometries, with a “more predictable path from design transfer through to validated production.”
“With Biofuse, customers can design lattices to their exact requirements,” added Dr. Bryan Naab, Additive Lead at Croom Medical. “That might mean replicating a porous structure previously produced through coating methods, or proposing lattice characteristics. The flexibility of the platform gives OEMs confidence that their design intent can be realised consistently and in line with regulatory expectations.”
