Client Overview

• Name: Vytruve
• Location: Rennes, France
• Sector: Medical Devices / Orthotics & Prosthetics
• Application: Digital workflow for custom prosthetic sockets

Technologies Used: SHINING 3D EinScan H2, SDK integration, custom socket design platform

Challenge: Manual Socket Fabrication in Prosthetics

Traditional prosthetic socket production is a time-intensive, manual process involving multiple plaster-based steps:

• Direct molding of the patient’s stump using plaster
• Creation of a counter-mold and manual adjustments
• Thermoforming, trimming, and assembly with other prosthetic components

This analog workflow can take several hours per patient, introduces fit variability, and requires physical discomfort for the patient during the mold-making phase. Furthermore, it limits scalability for prosthetic clinics.

Solution: Fully Digital Workflow with 3D Scanning and Printing

Vytruve developed a complete digital prosthetics solution to replace plaster molding with a non-contact, high-precision 3D scanning and printing process. The workflow consists of:

• 3D Scanning: Using SHINING 3D’s EinScan H2 handheld scanner
• Custom Software: An intuitive design platform with preconfigured socket libraries
• 3D Printing: Outsourced or in-house additive manufacturing of prosthetic sockets

The entire process—from scan to print-ready model—can be completed in under 48 hours.

Technology in Focus: SHINING 3D EinScan H2

Vytruve selected the EinScan H2 scanner for its ability to meet four critical clinical and technical requirements:

1. Color Capture
   Prosthetists use anatomical markings on patients’ limbs. The H2’s integrated 5MP color camera preserves these details during scanning, ensuring accurate trimline and alignment.

2. Movement Compensation
   Designed for body scanning, the H2 includes motion tolerance algorithms, enabling high-accuracy scanning even with slight patient movement.

3. High Precision
   Achieves scan accuracy up to 0.05 mm with mesh resolutions of 0.2 mm, delivering the precision required for daily-use prosthetic components.

4. Portability and Ease of Use
   Packaged in a compact, mobile-friendly case, the EinScan H2 can be deployed in clinics, hospitals, homes, and even mobile setups like vehicles.

Software Integration: Streamlined Design with Custom SDK Interface

Vytruve leveraged the EinScan H2 SDK to develop a user-friendly interface, eliminating unnecessary functionality and offering pre-set scanning parameters tailored for prosthetic applications. Their design platform also features:

• A library of over 120 socket templates
• Intuitive editing tools for shape customization
• Direct integration with in-house or outsourced 3D printers

The software significantly reduces the learning curve for prosthetists, enabling fast, repeatable, and patient-specific designs without advanced CAD experience.

Results: Faster Turnaround, Greater Comfort, Improved Workflow
Lead Time: Reduced from multiple days to under 48 hours

Patient Experience: Contactless scanning improves comfort and safety

Clinician Efficiency: Allows prosthetists to spend more time with patients, less time on fabrication

Scalability: Clinics can now produce sockets in-house with minimal training

Conclusion

Vytruve’s partnership with SHINING 3D demonstrates the transformative potential of digital technologies in orthotics and prosthetics. Their end-to-end solution delivers faster production, consistent socket quality, and a significantly improved experience for both clinicians and patients.
