Tekna (OSE: TEKNA), a provider of advanced materials to various industries, is introducing advanced Ti64 coarse powders for Laser Powder Bed Fusion (“L-PBF”) printing machines, unveiling a multitude of benefits for users.
In today’s rapidly evolving technological landscape, the advancement of L-PBF printing machines has opened new possibilities for using larger powder size, marking a transformative shift in the market. Addressing this emerging demand, Tekna is introducing the range of Ti64 coarse powders, specifically engineered for L-PBF applications. These powders are optimized for use with varying layer thicknesses, including 60 µm, 90 µm, and above.
By leveraging its proprietary plasma atomization technology, Tekna produces Ti64 powders that are highly spherical and free from internal porosity. This results in powders with higher density and flowability, which translates into superior mechanical properties in the final printed parts. Consequently, this enhances the end-user production yield and part reliability.
Real-world benefits
Feedback from customers across diverse industries highlights the multifaceted advantages of using Tekna’s Ti64 coarse powders in various L-PBF machines. These include significantly improved productivity, economic efficiencies in raw material sourcing, and safety measures, reinforcing the transformative impact of Tekna Ti64 coarse powders.
The use of thicker deposition layers leads to reduced production times, which enhances productivity and lowers the end-user overall production costs. This economic advantage, combined with the reduction in powder costs, makes the process more cost-effective. Furthermore, the ability for the end-user to procure Ti64 coarse powders and finer L-PBF size fractions manufactured from the same dedicated plasma atomizers accelerates the industrial qualification.
More parts, less risk
From a safety perspective, finer powders commonly used in LPB-F applications are often classified as flammable. In contrast, Ti64 coarse powders produced by Tekna have a lower sensitivity to oxygen thus reducing risks related to powder handling and recycling as well as costs associated with storage and transport.
“Our commitment to safety is essential, both for users and the environment. Thanks to their reduced reactivity, Ti64 coarse powders are not classified as flammable and are not sensitive to static electricity, making them safer to handle. This also simplifies logistics, allowing for easier transportation and compliance with local storage regulations. Ultimately, these advancements reflect our dedication to delivering high-quality products that prioritize safety and efficiency at every stage”, said Rémy Pontone, VP Sales & Marketing at Tekna.
Ti64 coarse powders can significantly improve productivity. Based on recent qualifications performed on well-known printing platforms, the productivity for a given part increased from 123 cm³/hr at a 60 µm layer thickness to 254 cm³/hr at a 90 µm layer thickness. Printing thicker layers provides better energy dissipation, which contributes to fewer deformations. This reduces the number and complexity of part supports required during printing. It therefore contributes to decreased post-processing time and costs.
