Vacuum Impregnation Vacuum impregnation involves soaking 3D printed parts in resin or sealant under vacuum to fill micro-voids, enhance mechanical properties, and improve water or chemical resistance. It strengthens layer bonding, dimensional stability, and surface finish. Vacuum impregnation is particularly useful for porous materials, powder-based prints, or functional prototypes requiring durability and sealing. Proper resin selection, vacuum pressure, and curing settings ensure consistent impregnation and reliable performance. It expands applications in automotive, aerospace, and consumer products for enhanced strength, insulation, and protection. |
