All You Need to Know About Nylon for 3D PrintingNylon, also known as Polyamide (PA), is a widely used polymer in the additive manufacturing sector. It is available in both powder and filament forms for various 3D printing technologies such as SLS (Selective Laser Sintering), Multi Jet Fusion, and FDM (Fused Deposition Modeling). Let’s explore the characteristics of nylon when used for 3D printing, its production, and applications.Get more news about pa powder printing,you can vist our website!
Production and Characteristics of NylonNylon Origins: Nylon first appeared in 1935 as nylon 6.6, developed by chemist Wallace Carothers at DuPont. It remains one of the most widely used materials today. Another type, nylon 6, was patented in 1941. Two commonly used nylons are PA11 (made from castor oil) and PA12 (made from petroleum).Environmental Impact: There’s ongoing debate about nylon’s environmental impact. PA11 is more eco-friendly due to its natural origin, but even it isn’t fully recyclable. In 3D printing, nylon powder can be reused for multiple prints.Nylon in 3D PrintingFilaments: Nylon filaments, particularly PA6 (with 6 carbon atoms), offer flexibility, impact resistance, and abrasion resistance. However, a heated build plate (around 80°C) is necessary for successful printing due to adhesion issues.Powder Form: PA12 (also known as PA2200) is widely used in powder form for SLS technology. It balances mechanical strength, flexibility, and heat resistance, making it suitable for functional prototypes and end-use parts2. PA12 is derived from petroleum and has excellent mechanical properties.Other Nylons: PA11 (Nylon 11) is biocompatible and used in medical applications via SLS technology. Evonik’s PA613 is based on polyamide 613 and suitable for higher-temperature 3D applications.In summary, nylon offers versatility, durability, and flexibility in 3D printing, making it a valuable material for various applications. Remember to choose the right type of nylon based on your specific requirements
