Abstract:

Nylon 6 is a type of synthetic polymer linked by amide groups. Nylon 6 polymers can be made by copolymerization of a molecule containing two amine groups with one containing two carboxylic acid groups. Nylon 6 is a semi crystalline polymer, meaning it contains both crystalline and amorphous regions that strongly influence its mechanical strength and processing behavior.In industry, Nylon 6 is used for textile applications and high strength industrial products, including ropes, carpets, automotive and industrial cords, apparel, seat belts, and parachutes. Nylon 6’s adaptability across multiple industries stems from key material properties, including flexibility, hardness, toughness, and dimensional stability under stress and temperature changes.This research focuses on Nylon 6 because there are still gaps in understanding how to optimize its performance, especially as its popularity continues to rise. The study investigates Nylon 6’s physical behavior, especially crystallization in the context of 3D printing: Examination/evaluation of 3D printing conditions for Nylon 6 such as printing bed temperature.By exploring these factors, the project aims to deepen the understanding of Nylon 6’s material response, including how its crystalline and amorphous regions change during crystallization, to help identify ways to enhance its usefulness in industrial and laboratory settings.
