Automotive applications
In the automotive industry, users manufacture components like exhaust systems, high-performance engine parts, and lightweight frames using titanium filament. In such applications, the ability of the filament to withstand high temperatures while still remaining strong is essential. Also, the use of such components increases the efficiency of the vehicle.
Marine industry
The marine industry uses titanium filament to manufacture components like propellers, pumps, and marine fasteners. In this industry, the corrosion resistance of titanium is a key factor. Thus, it makes it ideal for components that are exposed to harsh saltwater environments.
3D printing with titanium filament requires careful consideration in areas like printer settings, design considerations, and post-processing techniques. Below are the details:
Printer settings
3D printers used to print titanium filament should have a powerful nozzle and extruder. This is necessary because titanium requires high temperatures to melt and bond properly. Normally, the printing bed temperature range is between 100°C to 120°C. On the other hand, the extruder temperature range is between 120°C to 220°C. For a successful print, ensure the bed and nozzle temperatures are within these ranges. Interestingly, titanium filament is often paired with specific materials like a hardened steel nozzle. This is because it is an abrasive filament that can wear down softer nozzles.
3D printer maintenance
Maintenance of the 3D printer used for titanium filament is critical when creating titanium prints. Frequent checks for wear or clogs in the nozzle are necessary. This is because titanium filament creates very fine particles. These particles can easily cause clogs or create abrasive wear marks on the nozzle. Also, ensure the printing area is clean and clear of debris.
Design considerations
For successful titanium prints, users should keep certain design considerations in mind. When creating a model, users should ensure that the design has minimal re-entrant angles and thin walls. Thin walls and minimal re-entrant angles promote a successful printing process. This is because titanium has a tendency to warp during the printing process. Also, incorporating support structures is necessary when printing overhangs, as they prevent sagging.
Post-processing
Post-processing helps improve the mechanical properties and surface finish of titanium prints. The most popular post-processing method is the use of sanding and polishing techniques. In these techniques, they smooth the surface of the printed parts. Apart from improving the aesthetic of the part, the techniques also improve the functional part. Additionally, techniques like heat treatment help enhance the strength and overall toughness of the part.
There is a wide range of benefits that businesses can get from printing supplies titanium filament. This is due to the exceptional qualities of titanium.
Lightweight and high strength
One of the key benefits that buyers get from titanium filament is its high strength and low weight. Even though it is as strong as steel, it is 45% lighter than steel. This amazing weight-to-strength ratio makes it ideal for creating parts that require such features. These include components like aircraft frames and engine parts, where every bit of weight counts.
Corrosion resistance
Another benefit of titanium filament is its exceptional corrosion resistance. Even though it is exposed to harsh environments, such as saltwater or acidic conditions, it will not degrade. This property makes titanium filament a preferred material in marine and chemical processing industries. In these industries, durability is key to ensuring long-term product reliability.
Biocompatibility
Titanium has a wide range of applications in the medical field. This is due to its amazing biocompatibility property. As mentioned earlier, it does not cause adverse reactions when it comes in contact with living tissues. This makes titanium filament ideal for manufacturing medical implants, surgical tools, and prosthetics. Using this filament in medical equipment ensures a long-term product that is safe for use in medical procedures.
Heat and wear resistance
Titanium filament has impressive heat and wear resistance. It can maintain its mechanical properties in extreme temperatures. In addition, it is highly resistant to abrasion. These qualities make it particularly advantageous for applications in high-performance engines, aerospace components, and cutting tools. In these cases, titanium withstands extreme conditions without wearing down or losing its structural integrity.
