DLP (Digital Light Processing) printers are known for their high precision and speed in producing detailed 3D models using photopolymer resins. However, the printing process alone isn’t enough to ensure the full strength and durability of printed objects. After printing, the resin is only partially cured, leaving it soft and potentially fragile. This is where a curing system becomes essential. A curing system uses UV light to further harden the resin, ensuring that the printed model reaches its maximum strength and chemical resistance. During this post-curing phase, the UV light completes the polymerization process, locking the resin molecules into a stable, solid state. This step not only enhances the mechanical properties of the printed object, making it more durable and reliable, but it also improves surface hardness and ensures the model’s dimensional accuracy is maintained over time. For functional parts or items that will be subjected to stress, heat, or moisture, post-curing is crucial to achieve the necessary performance standards. Without a curing system, DLP prints may remain brittle or prone to warping, reducing their longevity and functionality.
