Technology & Products
Key Products
Metal LPBF printing (EOS M270, EOS M290, AMCM M290 2×1 kW systems); Material portfolio: Nickel Superalloys (IN718, IN939), Titanium, Copper, Aluminum, Steels (Stainless 316L, Tool Steel MS1, Tool Steel MS2); Design co-development and simulation; Post-processing and finishing; Quality testing and documentation; 3D scanning for spare parts; Hybrid manufacturing (AM + traditional combined)
Technological Advantage
CLAIMED: Deep material knowledge and optimization capability enables cost reduction (topology-optimized designs reduce component count, consolidate assemblies) and supply chain efficiency (on-demand production eliminates long lead times, reduces spare parts inventory). VERIFIED: Partnership with Gränges Powder Metallurgy on high-performance aluminum alloys; collaboration with EOS Finland on IN939 superalloy development; demonstrated use of print simulation to compensate for heat-induced deformations in demanding geometries (support-free structures). Hybrid manufacturing approach combining AM with CNC finishing allows optimization of production method for each part segment.
Differentiation
Value Proposition
Reduces lead times from weeks to days for metal component production; enables topology optimization and part consolidation (fewer components, same function); offers comprehensive AM chain including design co-development and finishing; provides material expertise (11+ alloys from superalloys to aluminum) with hybrid manufacturing capability combining AM with traditional methods for optimized solutions.
How They Differentiate
Delva claims Finland's widest material portfolio (11+ engineered alloys) and is described as 'biggest metal AM service provider in Finland' with deepest materials expertise. Differentiates via hybrid manufacturing approach (AM + traditional methods combined), customer co-development model emphasizing design optimization, and expert process simulation to overcome print challenges. Superior to generic service providers through material science depth and topology optimization expertise; differentiation against international LPBF vendors through Finnish local presence and Nordic ecosystem integration.
