Geometric Complexity Without Cost Penalty

On- Demand andLow- Volume Production

Nuclear facilities often requires small quantities of highly specialized parts - replacement inserts for aged equipment, one-off adapter for experimental setups, or upgrades for instrumentation that was designed decades ago. Traditional producturing is illl- appropted for such low- volume runs due to high setup costs and minimum order quantiquantities. 3D printing eliminates these conquiers.

Material Efficiency ency andWaste Reduction

Nuclear- grade materials - speciality alloys, high- performance polimers, and ceramics - are locsive and often require rigorous supply chain controls. Traditional subtractive processes can waste 50- 80% of thee material as chips or cramp. 3D printing is an additiva process, building parts layer by layer and using only the material requid for thee final object (plus support structures).
