Ceramic additive manufacturing for sustainable industry
Background
Advanced manufacturing is evolving rapidly, with additive manufacturing playing a key role in enabling more flexible, efficient and sustainable production processes. In particular, ceramic 3D printing enables the fabrication of complex, tailored structures for high-performance applications such as thermal management and energy systems.
TECH4FAB (Cross-border advanced manufacturing technology park for a more resilient, sustainable and competitive industry) is an Interreg France–Wallonia–Flanders project that brings together leading research centres, universities and industrial partners.
The project focuses on the development and validation of advanced manufacturing technologies, with a strong focus on additive manufacturing of complex materials, including ceramics.
A cross‑border platform
Within TECH4FAB, partners collaborate in a cross‑border innovation platform to develop and validate new manufacturing routes. One key focus is 'freeform' additive manufacturing of ceramic-based structures, enabling layer‑by‑layer fabrication without the use of molds. This approach allows the design of complex, tailored geometries that are not achievable using conventional processing.
These developments target applications where controlled architecture, porosity and material composition are critical, such as thermal management components.
From materials to 3D printed structures
Centexbel contributes to this development by focusing on material formulation and processing of ceramic additive manufacturing.
This work includes:
- Development of highly filled ceramic compounds, including recycled and functional materials
- Pellet-based additive manufacturing, from material formulation to 3D-printed components
In addition, Centexbel develops 3D textile-based structures that act as support for complex ceramic architectures. This combination of material engineering and processing enables new design possibilities for hybrid and multifunctional structures.

Circular and efficient manufacturing
The ceramic additive manufacturing activities are validated through industrial demonstrators, where technologies are tested under realistic conditions and brought to higher technology readiness levels.
These developments enable the production of complex ceramic components, improve process flexibility compared to conventional shaping, and allow the integration of tailored functionalities. At the same time, the use of recycled and optimized materials supports the transition toward more resource-efficient and circular manufacturing processes.
By combining ceramic additive manufacturing, material innovation, and recycling strategies, TECH4FAB contributes to more sustainable and efficient production systems.
Sustainable manufacturing ecosystem
By combining innovation, collaboration, and industrial validation, TECH4FAB contributes to a more resilient and sustainable manufacturing ecosystem in Europe.
The project demonstrates how advanced technologies can be integrated into existing industrial processes, supporting companies adapt to future challenges while maintaining efficiency and performance.
