Tekna’s Entrance into the L-PBF Market

Tekna, a leading provider of advanced materials, has recently announced its foray into the L-PBF market with a new range of Ti64 coarse powders. But what sets these powders apart? The answer lies in their ability to significantly enhance productivity and cost-efficiency without sacrificing quality.

The Significance of Coarse Powders

In traditional L-PBF processes, finer powders are often used to achieve high precision. However, they come with their own set of challenges, including higher flammability and sensitivity to oxygen. Tekna’s Ti64 coarse powders provide a safer alternative while offering robust mechanical properties and better flowability.

Advantages of Coarse Powders:

Feature	Traditional Fine Powders	Tekna’s Ti64 Coarse Powders
Flammability	High	Low
Sensitivity to Oxygen	High	Low
Flowability	Moderate	High
Mechanical Properties	Strong, but may vary	Consistently high
Ease of Handling	Requires stringent safety measures	Simplified logistics and safer to handle

The Role of Plasma Atomization Technology

One of Tekna’s crucial differentiators is its proprietary plasma atomization technology. This advanced technique produces highly spherical powder particles with minimal internal porosity, improving the overall density and flowability. As a result, you get powders that offer superior mechanical attributes in the final printed components.

Benefits of Plasma Atomization

This technology isn’t just a marketing buzzword; it’s a game-changer. By producing powders that are almost perfect spheres, Tekna ensures that each grain generates optimal contact during the L-PBF process. The spherical shape aids in better energy dissipation, which reduces deformations and increases part reliability.

Standard	Ti64 Coarse Powders Value	ASTM Standard Value
B348-21	Meets	Meets
F3001	Meets	Meets
F136	Meets	Meets

Safety First: Understanding the Safety Aspects

Handling fine powders often involves rigorous safety protocols. They are flammable and sensitive to static electricity. Tekna’s Ti64 coarse powders, on the other hand, are designed with safety in mind. They have a much lower sensitivity to oxygen, which significantly reduces the risk involved in handling, recycling, storage, and transportation.

Simplified Logistics

Reduced reactivity makes these coarse powders easier to manage. They don’t require stringent anti-flammability measures or special storage conditions, which simplifies logistics and ensures compliance with local storage regulations.

Rémy Pontone’s Insight

“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.

Improved Productivity Metrics

Enhanced Production Rates

Recent qualifications on well-known printing platforms demonstrated remarkable productivity increases. For a given part, productivity rose from 123 cm³/hr at a 60 µm layer thickness to 254 cm³/hr at a 90 µm layer thickness. This is largely due to the thicker deposition layers, which improve energy dissipation and reduce deformations.

Cost Benefits

By printing thicker layers, the overall production time is reduced, leading to enhanced productivity and lower end-user production costs. The lowered powder costs combined with these efficiencies make the entire process more cost-effective.

Reduced Post-Processing Needs

Fewer deformations during the printing process result in fewer and less complex supports for the parts. This in turn reduces the amount of post-processing required, saving both time and costs.

Summary of Productivity Gains:

Layer Thickness	Productivity (cm³/hr)	Energy Dissipation	Deformations	Post-Processing
60 µm	123	Moderate	More	More
90 µm	254	Enhanced	Fewer	Less

Accelerated Industrial Qualifications

The ability to procure both Ti64 coarse powders and finer L-PBF size fractions from the same plasma atomizers accelerates industrial qualification processes. This capability ensures a seamless switch between different material grades, meeting various application needs without additional R&D investment.
