SI-BONE Achieves Design-at-Scale of Additive Implants with Batch Processing

To tackle the challenge, SI-BONE's engineers used nTopology to develop and automate their design workflows. They first created a proprietary highly-porous trabecular structure and then applied the standardized osseointegrative structure to a product line of more than 70+ parts using a simple script. This approach saved valuable engineering time and operational costs. The engineering team fully defined every parameter of the highly-porous trabecular lattice structure using nTopology. They created workflows that controlled key design parameters, including lattice beam thickness and pore size, and explored multiple design variations. They also ensured smooth transitions between the porous regions and the structurally critical, solid parts of the implant using Field-Driven Design. To ensure consistency and traceability, the team generated reports with each part, documenting critical design outputs in a text file. They packaged the workflow into a single, custom nTop block that exposed only the necessary inputs and outputs to the user. This allowed the engineers to share the lattice generation workflow with other team members while remaining compliant with transparency and traceability requirements.
