About Customed
Customed (customed.ai) is a medical-technology company that mass-produces patient-specific instruments (PSIs) for orthopedic surgeons. Its end-to-end platform — an operating system for personalized surgery — turns medical scans into patient-specific surgical plans, tools and implants, giving surgeons guides that are designed for one patient and used directly in the operating room.
The Challenge
Patient-specific instruments leave no room for error: each PSI must sit on a very specific area of the patient’s bone and mimic its anatomy precisely — otherwise the guide simply won’t work. And because Customed’s customers are surgeons who care a lot about speed, the performance of the geometry engine behind PSI generation was non-negotiable. Mass production meant running intensive Boolean operations on complex bone geometries — fast, accurately and predictably, case after case.
The Solution
After extensive research and comparison of the available options, Customed chose MeshLib as the geometry core of its PSI pipeline and integrated MeshLib Boolean to power instrument generation:
Fast Mesh Boolean: cutting patient-specific guides from complex bone geometries at production speed.
Accuracy & Predictability: precise, repeatable results on anatomy the guide must mimic exactly.
Tunable Speed vs Precision: full control to fine-tune the trade-off for every product and use case.
Ready-to-use Code Samples: working code from the MeshLib team that shortened integration.
The Results
With MeshLib integrated into the pipeline, Customed greatly increased processing speed for PSI generation while maintaining the strict accuracy and predictable outcomes that surgery demands. The team can fine-tune speed versus precision for each use case — and relies on a partner whose support exceeded expectations, with questions answered on the spot or by the next day, often together with working code.
In Their Words
“Working with the MeshLib team was a very, very good experience — actually above what I expected. The team is always there, responsive, solving problems that I would not have expected them to actually solve. They would send you the code that performs what you wanted, and every time you have a question — where is this function, how can I get this functionality — you would get the answer very quickly, if not on the spot then the next day. It’s actually really a pleasure to work with them.”
