Resin and filament 3D printersdiffer in the material used for printing. Resin printers use liquid resin cured by UV light, offering high-detail and smooth finishes, ideal for intricate models. Filament printers use thermoplastic filaments, which are more durable and versatile, suitable for larger, functional prints. Resin printers excel in detail, while filament printers are better for strength and size.
