It's also food-safe, making it a good choice for things like food containers and kitchen gadgets. PETG is a versatile material that's great for a wide range of applications.
• Nylon (Polyamide): Nylon is a strong and flexible plastic that is often used for gears, hinges, and other functional parts. It's resistant to abrasion and chemicals, making it suitable for tough environments. Nylon is a bit more challenging to print, but it offers excellent performance characteristics.
• Resin: Resin is used in a variety of 3D printing technologies, including SLA (stereolithography) and DLP (digital light processing). It allows for incredibly detailed and smooth prints, making it great for intricate models, prototypes, and jewelry. Resins can come in various formulations, each with unique properties, such as high strength, flexibility, or heat resistance.
• Polycarbonate: Polycarbonate is a high-performance plastic known for its exceptional strength, impact resistance, and heat resistance. It's often used in automotive parts, electronic housings, and other demanding applications. Printing polycarbonate requires advanced printers with heated chambers to prevent warping.
