Industrial additive manufacturing of metal parts
Production of metal parts using 3D laser printing
At DOUBLE CŒUR, an industrial subcontractor with expertise in additive manufacturing, we produce technical metal parts in small series or POC, using DED laser wire and DED laser powder technologies. This3D metal printing approach enables us to meet your requirements in terms of performance, complex geometry or miniaturization.
Our industrial infrastructure guarantees agile, reproducible production that complies with quality standards. Whether it’s a prototype or a ramp-up, each part benefits from a high level of traceability and perfect adaptation to your functional constraints.
Our promise: ready-to-use, compliant metal parts, produced quickly and drift-free, from prototype to production run.
Your partner in additive manufacturing, for controlled production from the very first part
Our expertise in additive manufacturing
Our know-how is based on in-depth mastery of the critical parameters of industrial additive manufacturing: laser power, deposition rate, trajectory strategy, inter-pass temperature and metallurgical homogeneity. Each step is controlled to guarantee consistent, reproducible material quality.
Thanks to this rigorous approach, we produce compliant metal parts from the very first piece, with optimized material density, homogeneous microstructure and high geometric precision, even on complex shapes or sensitive materials.
We work on both one-off and small series production, from functional prototypes to large-scale metal parts.
Validated mechanical strength
High material density guaranteed
Metallurgical homogeneity preserved
Controlled dimensional stability
Guaranteed geometric accuracy
Controlled deposit regularity

Secure your metal additive manufacturing production, without disruption
At DOUBLE CŒUR, metal additive manufacturing is a strategic industrial lever. From design to material deposition, we secure every stage of the process to guarantee high-performance, reliable metal parts that meet industrial requirements.
1. Demystifying additive manufacturing for beginners
Many manufacturers using conventional processes (machining, casting) want to move into metal additive manufacturing, but lack the necessary expertise. DOUBLE CŒUR can help you make the right technological and economic choices right from the start.
More than just a prototyping service, we offer a complete industrial process:
- Additive design and redesign
- Prototyping, technical validation
- Strategic consulting
Our strength: a robust industrial infrastructure and proven expertise in DED (wire & powder) processes. We transform your constraints into reliable, reproducible and profitable metal parts.
Your benefit: integrate the additive with peace of mind, with a partner who guarantees quality and profitability right from the start.
2. Support for pre-production and ramp-up
DOUBLE CŒUR ensures controlled production from pre-production through to small production runs.
- Industrial-scale validation, without heavy investment
- High-performance machinery
- Volume adaptation: reliability, stability, compliance
Your advantage: flexibility and performance to meet fluctuating production needs.
3. Overcoming internal limitations and managing emergencies to guarantee continuity
DOUBLE CŒUR responds rapidly to capacity saturation, unforeseen demand, breakdowns or maintenance to ensure continuity of your additive production.
- Fast, agile ramp-up
- Maintaining quality and rigorous traceability
- Urgent delivery of compliant parts
- Flexibility to absorb peaks without breakage
- High-performance production line without heavy investment
Your peace of mind: a continuous, high-performance chain, without excessive investment.
4. Repairs & remanufacturing: bringing your parts back to life
Additive manufacturing is ideal for repairing or refurbishing complex metal parts.
- Durable, precise solutions
- Compliance with industry standards
- Controlled costs, minimal impact on production
5. End of cycle or transition: optimizing final volumes
At the end of a production run or when a range is changed, we can take charge of your last batches.
- Making the last volumes profitable
- No need for additional in-house resources
- Respect for quality and deadlines
Your advantage: maintain your peace of mind and move ahead with new developments.
