3D printing, also known as additive manufacturing, has had a far-reaching impact in various industries. So, how to choose the 3D printing process and materials that suit your needs? In recent decades, the development of 3D printing technology has proved that this technology has brought great advantages to consumers, designers, engineers and manufacturers. Traditional production methods have limitations in manufacturability, while 3D printing benefits from the incremental method of building parts layer by layer, which has unparalleled design freedom. Since additive manufacturing does not require tools, it has become a very fast production method, which can make parts turnover within hours or days. The shortening of supply chain and the improvement of production efficiency are the reasons why many enterprises (from start-ups to Fortune 500 enterprises) incorporate them into their workflow.
However, in the process of using 3D printing technology, problems such as various additive manufacturing systems, their inherent quality, related materials, and the cost of external operations and outsourcing to contract manufacturers may arise. Next, we will analyze the common types of additive manufacturing, related processes and systems, and how to determine which additive manufacturing solution Z is suitable for your project. There are four main 3D printing technologies
3D printing, and there is often an update process. The manufacturing process of each additive uses different materials to produce components with unique properties that can be poorly applied to specific applications.
3D printing materials
In the traditional manufacturing methods, almost unlimited kinds of materials are available. Unlike traditional manufacturing methods, 3D printing is bound to the materials used in each specific system and machine. At present, most additive manufacturing parts can be plastic or metal, which also depends on the process selection of some composite materials.
Manufacturing materials require certification and mechanical properties that meet industry-specific requirements, such as aerospace flame rating and medical biocompatibility. Different industries have different requirements for durability, appearance and tolerance. According to the performance requirements of 3D printing parts, the corresponding processes and materials will be different. If the parts need to be similar to the final product appearance, or need to maintain the shape of the static model, the paint technology may be the worst method, because its turnover speed is slow, and the surface is smooth and natural. Stereo lithography is also a good choice for entertainment props or large concept models that require post-processing to polish the surface.
