VTT 3DMetalprint

Cost-effective and optimised products through digital revolution

VTT 3DMetalprint brings top level expertise and unique infrastructure to support your 3D development activities. It enables a new, economical way to produce optimised and cost-effective products with digital process. The concept takes into account the application-specific aspects as well as the overall process efficiency.

Application services

Competitive products and new business models

Additive manufacturing (AM) offers many opportunities to improve product performance and produce totally new products. Embedded intelligence in 3D-printed components opens new business and development opportunities. Printed digital spare parts affect on business models and supply networks already now. VTT 3DMetalprint brings these and other novel AM applications to customer.

​Production services

Commissioning support for the new technology

Both component and process are designed and optimised to achieve both optimal quality and economical manufacturing process. Every material requires specific process parameters to ensure flawless products. When focusing on final part production, AM process needs to be integrated as integral part to production chain and developed towards smart manufacturing. VTT's versatile expertise accelerates realisation of this.

Material services

Increased quality and material performance

Do you have a suitable application but not the suitable material? VTT 3DMetalprint can tell you if the material is suitable for the application and help with the  implementation. VTT has a long experience and an excellent infrastructure to tailor metal powders and their properties. Materials can be developed towards better performance and functionality. For example, we have invested in the development of the magnetic AM materials.
