Modern 3D printing is revolutionizing the defense industry, opening new possibilities for producing durable and functional components. A perfect example is the night vision device housing, made using HP Multi Jet Fusion (MJF) technology – a solution that combines the highest precision, unmatched durability, and resistance to extreme conditions. This innovation is designed for demanding military applications where every detail matters.
MJF – a robust technology for defense applications
HP Multi Jet Fusion technology is based on layer-by-layer sintering of polyamide powder (PA12) using special agents that activate the sintering process. A key advantage of this method is the production of uniform, densely sintered parts with high isotropic mechanical properties.
For the night vision device housing, precise replication of the design was crucial so that all electronic components could be fitted with maximum accuracy, creating a cohesive and fully functional assembly. Thanks to the dense layer structure, MJF enables the production of components with stable dimensions and low water absorption, ensuring reliability even in harsh environmental conditions.
Finishing – precision, durability, aesthetics
3D printing is only the beginning. To ensure proper functional properties and the appearance of the final product, the printed part was subjected to finishing processes: bead blasting, which gives the surface a uniform, matte texture, and shot peening, which increases resistance to vibrations and material fatigue. Additionally, the part was dyed black to enhance aesthetics and camouflage properties. The result is a durable, precisely finished component that meets the requirements of military equipment.
Advantages of MJF technology in the defense industry
Multi Jet Fusion technology combines high precision, speed, and flexibility, making it ideal for both prototyping and serial production – where turnaround time and accuracy are critical. It allows manufacturing components tailored to specific operational needs, ensures dimensional repeatability, enables coloring, and eliminates the need for support structures.
MJF excels in producing parts such as grips, covers, optics adapters, communication device housings, and structural elements of portable equipment, effectively supporting innovation in the modern defense industry.
