The development and manufacturing of medical devices —from orthopaedic implants to surgical instruments, miniaturised devices and technical hospital components— involve extremely demanding requirements in terms of safety, structural validation, dimensional control and traceability.
Minor internal defects, minimal geometric deviations or assembly failures can compromise clinical performance, regulatory compliance or patient safety.
NM3D Ibérica positions itself as a specialised technical service provider for the healthcare sector, supporting manufacturers and R&D centres with non-destructive testing, dimensional metrology, 3D digitisation, reverse engineering and additive manufacturing, designed to solve real development, industrialisation and production challenges.
Real Manufacturing Issues in Medical Devices That Require Advanced Technical Testing
Medical device manufacturers commonly face:
- internal defects not externally visible
- porosity in additively manufactured metal implants
- internal misalignments in assembled devices
- critical dimensional deviations
- deformation after thermal processes
- challenges validating complex internal geometries
- need for rapid root cause identification
These issues cannot be resolved through visual inspection or surface measurement alone. They require advanced technical testing and internal analysis.
X-ray and Industrial Computed Tomography Testing
Addressing Internal Integrity in Critical Medical Components
Industrial CT is one of the most critical testing methods in the medical sector, enabling internal analysis without dismantling or destruction.
Problems solved:
- identification of internal porosity in implants
- detection of structural discontinuities
- validation of internal channels and geometries
- inspection of assembled devices
- structural integrity verification prior to final approval
Decisions enabled:
- batch acceptance or rejection
- design validation
- adjustment of additive manufacturing parameters
- regulatory documentation support
- root cause analysis of failures
Dimensional Metrology for Medical Devices
Ensuring Precision, Repeatability and Compliance
Dimensional metrology ensures implants and medical devices meet strict functional tolerances.
Problems solved:
- assembly fit issues
- sealing failures
- dimensional variation between batches
- initial validation non-conformities
Services provided:
- full dimensional inspection
- first article validation
- in-process dimensional control
- laboratory and on-site measurement
3D Digitisation and Reverse Engineering as Diagnostic Tools
When CAD no longer reflects reality
Many projects require understanding deviations between nominal design and actual manufactured parts.
Problems solved:
- missing or outdated CAD models
- need for redesign
- deformation analysis
- digital documentation for validation
Additive Manufacturing as Direct Support for Development and Validation
Rapid response without compromising clinical timelines
Additive manufacturing enables:
- functional prototypes
- customised devices
- small production batches
- hospital support components
Integration with metrology and CT ensures full dimensional and structural validation.
