A new technology that is posing a threat to existing production practices. However, if additive manufacturing is to be widely employed, the corrosion behavior of additive manufacturing parts must be taken into account.
There has been a great influence on improving printing technologies over the last few decades, including extremely dependable lasers, low-cost HPC hardware and software. Metal 3D printing has received attention recently in comparison to other manufacturing methods due to its particular benefits in the creation of metal products.
Let's take titanium based alloys as an example. Since titanium combines a wide range of industrial applications for high-performance parts with high processing costs, long lead times for hard molding and conventional processing, titanium and titanium alloys have attracted great attention in terms of additive manufacturing technology. Among titanium alloys, Ti6Al4V is the most widely used material for many engineering parts and biomedical implants.
The material is very bendable and corrosion resistant. These features make it excellent for use in a variety of industries. There are several advantages to using 3D-printed titanium.
The usage of titanium and 3D-printed components in aerospace applications frequently helps to cut purchasing rates. The connection between the weight of the material initially purchased and the weight of the final product is a phrase originated from the aerospace industry.
In normal production, for example, the buy/sell ratio for titanium airplane components might range from 12:1 to 25:1. This suggests that 12-25 kg of raw materials are required to manufacture 1 kilogram of components. Up to 90% of the material can be treated in this situation.
Metal 3D printing has the potential to lower the titanium ratio from 3:1 to 12:1. This is due to the fact that metal 3D printers often utilize only the quantity of material required to create the item and maintain the structure with minimal waste. It is more vital to cut procurement expenses than to save them for pricey materials such as titanium.
Due to topology optimization, additive printing may also improve the lightweight qualities of titanium. Engineers utilize topology optimization software to provide criteria such as load and stiffness limitations, and then allow the software tools to optimize the initial design to satisfy those specifications.
This optimization allows you to remove any extraneous materials from the design, resulting in a lightweight yet strong component. Topology optimized designs are typically only capable of being created using additive manufacturing technologies.
This benefit is especially valuable in the aerospace sector, where lightweight 3D-printed titanium components may save weight and increase aircraft performance. Despite the numerous benefits of titanium 3D printing, there are certain drawbacks to consider.
1. The first is the requirement for the development of standards for the use of titanium using additive technology. Some businesses have already begun to take measures in this direction.
2. The high cost of titanium powder is the second barrier. Titanium powder designed for 3D printing, for example, costs between $300 and $600. Titanium 3D printing has grown in popularity in the aerospace, pharmaceutical, and automobile industries.
The primary reason is titanium's better performance mixed with the ability to eliminate waste in 3D printing while creating complicated and lightweight shapes.
Titanium 3D printing will become an attractive production choice for a wide range of sectors in the future as titanium costs decline and additional uses are identified.
