3D Printing and product strength. Learn more now!
3D printing is an additive manufacturing process of creating three-dimensional solid objects from a digital 3D drawing, and successive layers of material are placed to form the product form. This technology is used in a wide variety of industries where product strength is critical, including automotive, aerospace, medical, and consumer products. The bond strength of the successive layers is crucial to the overall strength of the products, as is the material, printer orientation, and internal structure.
This article discusses the strength of 3D printed parts and what improves product strength. The article reviews the latest materials and other factors contributing to the overall strength of 3D-printed products. There are several factors for evaluating product strength that is also considered.
The strength of 3D printed parts depends on several factors, including the material used, the structural design, part orientation, and the printing process. Strength can vary significantly with 3D materials and the printing process. For example, ABS plastic is a standard 3D printing material that is strong and impact-resistant but not as strong as metals such as aluminum or steel.
While Acrylonitrile Butadiene Styrene (ABS) and Polylactic Acid (PLA) are among the most common thermoplastics used in 3D printing, the strongest parts use industrial-grade thermoplastics such as Polycarbonate, ABS, or Nylon. These materials are generally stronger than the PLA and other plastic filaments used in consumer-grade 3D printers. Industrial-grade thermoplastics are extremely heat-resistant and can produce parts with great detail and durability.
Other factors include the 3D printer settings and post-processing methods. These may include:
Material composition is vital to product strength. The most commonly used materials for 3D printing are plastic, metal, and ceramic. Generally, plastic materials used in 3D printing are not as strong as metals and ceramics, but they are strong enough for a variety of applications.
Overall, Polycarbonate is generally considered the strongest 3D printed filament, but there are several methods by which product strength is ascertained. The numerous strength measurements should be considered to optimize part production.
The strongest materials for tensile strength include:
The materials with the highest levels of elongations are:
The materials with the highest hardness levels include:
Materials with the best impact resistance include:
The materials with the best chemical resistance include:
The most flexible materials are:
Using 3D printing to make strong objects is logical because it is a cost-effective and efficient manufacturing method that has proven to meet or exceed the strength of conventionally manufactured products. 3D printing can create complex geometries with high accuracy and detail, enabling intricate details that would be impossible to achieve with traditional manufacturing methods. Additionally, 3D printing can produce parts with consistent quality and strength.
