Acrylonitrile Butadiene Styrene (ABS)
Material Introduction
Acrylonitrile Butadiene Styrene (ABS) is one of the most widely used engineering thermoplastics for industrial-grade 3D printing, known for its balanced combination of toughness, impact resistance, and dimensional stability. ABS offers greater mechanical strength and heat resistance than many commodity plastics, making it a preferred choice for functional prototypes, mechanical housings, fixtures, jigs, and medium-duty structural components. Through Neway AeroTech’s advanced ABS 3D printing, the material delivers consistent performance, reliable extrusion characteristics, and the ability to produce durable parts with smooth surfaces and fine detail. ABS is particularly valued for applications requiring machining compatibility, chemical resistance, and thermal endurance beyond what materials like PLA can achieve, supporting professional engineering workflows and end-use products.

Alternative Material Options
When ABS does not fully satisfy operational or environmental requirements, several alternate materials offer enhanced properties. For improved strength and fatigue resistance, Nylon (PA) or PETG are preferred for functional, load-bearing applications. If greater heat tolerance is needed, engineering plastics such as Polycarbonate (PC) offer much higher temperature stability. For flexible or elastomeric parts, TPU delivers excellent elasticity. For extremely high-performance environments that require chemical and thermal durability, high-performance plastics like PEEK offer outstanding engineering capabilities. If ultra-smooth surfaces or high detail are required, photopolymer resins can replace ABS for aesthetic or precision components.
Design Purpose
ABS was developed to offer a mechanically strong yet easily processed engineering polymer capable of providing durability, dimensional stability, and improved toughness. Its terpolymer structure combines acrylonitrile for chemical resistance, butadiene for impact strength, and styrene for rigidity and surface quality. In additive manufacturing, ABS is widely used for functional prototypes, mechanical components, and industrial tools that require heat resistance, machinability, and toughness. Its ability to balance strength and manufacturability makes it an essential material for engineering validation and end-use production.
