Battery manufacturing — from cell to module and pack — involves highly sensitive processes, multi-material systems and strict requirements for safety, quality and reliability. Small geometric deviations, internal defects or assembly failures can lead to performance losses, safety risks, production scrap or field failures.
NM3D Ibérica positions itself as a specialized technical service provider for the battery industry, supporting manufacturers and integrators with non-destructive testing, dimensional metrology, 3D scanning, reverse engineering and additive manufacturing, focused on solving real development, industrialization and production challenges.
Real Challenges in Battery Manufacturing That Require Advanced Technical Testing
In industrial practice, battery manufacturers face recurring issues such as:
- internal defects not visible externally
- geometric variations affecting assembly and sealing
- failures in welds, joints and interfaces
- internal misalignments in cells and modules
- deformations after thermal or assembly processes
- difficulties identifying root causes of failures
- the need to rapidly validate process changes
These challenges cannot be solved through visual inspection or superficial measurements alone. They require advanced technical testing.
Industrial X-ray and Computed Tomography Testing
Addressing Internal Issues in Cells, Modules and Packs
Industrial Computed Tomography (CT) is one of the most critical testing methods in the battery sector, as it enables internal analysis without disassembly or destruction.
Problems addressed:
- identification of internal defects in cells
- analysis of layer and component misalignment
- detection of voids, inclusions and discontinuities
- validation of welds and internal connections
- verification of structural integrity of modules and packs
Decisions enabled:
- accept or reject production batches
- adjust process parameters
- validate design changes
- identify root causes of production or test failures
NM3D Service: CT inspections with clear technical reports, 3D evidence and support for root cause analysis.
Dimensional Metrology Applied to Battery Components and Systems
Ensuring Proper Assembly and Production Repeatability
Dimensional metrology is essential to ensure that housings, modules, supports and interfaces meet functional tolerance requirements.
Problems addressed:
- assembly difficulties between components
- sealing and fitting failures
- deformations after manufacturing processes
- dimensional variations between batches
Testing and services provided:
- full dimensional inspection of housings and modules
- first article and pre-series validation
- in-production dimensional control
- laboratory or on-site measurements
Decisions enabled:
- validate dimensional conformity
- stabilize production processes
- reduce rework and scrap
- ensure series repeatability
3D Scanning and Reverse Engineering as Industrial Diagnostic Tools
When CAD No Longer Reflects Reality
In many battery projects, the challenge is not only measurement, but understanding how the real part deviates from the theoretical model.
Problems addressed:
- missing or outdated CAD models
- unexpected geometric deviations
- need to adapt existing components
- deformation analysis of plastic or structural parts
Services provided:
- 3D scanning of components and assemblies
- CAD-to-part comparison
- reverse engineering for correction and redesign
- digital documentation for production and maintenance
These tests accelerate technical decision-making and reduce unproductive iterations.
Additive Manufacturing as Direct Support for Industrialization and Testing
Solving Problems Quickly Without Stopping Production
In the battery sector, additive manufacturing is a practical tool to rapidly respond to industrial needs.
Typical applications:
- functional prototypes for validation
- assembly fixtures and jigs
- supports for testing and inspection
- auxiliary parts for production lines
- large-format components for validation
Problems addressed:
- development delays
- dependency on final tooling
- difficulties testing new solutions
- need for rapid production adjustments
Large-format production capability allows fast responses to real factory-floor challenges.
