In additive manufacturing, the choice of substrate defines the success of each build. Ti6Al4V, also known as Grade 5 titanium, has emerged as the gold standard for high-performance build platforms. At DLX, we’ve engineered our titanium substrates to push the boundaries of precision, reliability, and repeatability in 3D metal printing.
For more details, pls directly contact us.
Ti6Al4V is a titanium alloy composed of approximately 90% titanium, 6% aluminum, and 4% vanadium. This unique composition provides an ideal balance of strength and workability. With its high tensile strength and low density, the material ensures the platform remains rigid and stable even during intense thermal cycles. Additionally, its corrosion resistance allows it to endure repeated exposure to oxygen and heat without surface degradation.
In metal 3D printing, the build platform’s stability directly affects product accuracy. Warping, uneven thermal expansion, or substrate fatigue can lead to layer misalignment and print failure. DLX Ti6Al4V substrates are specifically designed to resist these challenges. We apply advanced machining and controlled heat treatments to achieve exceptional flatness and reduce internal stress — ensuring that each print starts on a solid, reliable foundation.
At DLX, we understand that every additive manufacturing system operates differently. That’s why our Ti6Al4V substrates are tailored to match various machine formats and build volumes. Using CNC machining and laser measurement systems, we guarantee uniform surface quality and thickness precision within micrometer-level tolerances.
We also employ double vacuum melting to eliminate impurities, enhancing thermal conductivity and mechanical consistency. This means faster heat distribution, reduced residual stress, and better adhesion between the first layers of printed parts and the substrate.

Industry Trends and Future Outlook
The growth of metal additive manufacturing is driving demand for high-quality build platforms. As 3D printing moves from prototyping to full-scale production, titanium substrates are becoming indispensable. Their combination of strength, thermal resilience, and reusability gives manufacturers a significant edge in both efficiency and reliability.
DLX continues to invest in material science and production automation to meet these demands. By refining our alloy treatments and machining processes, we are creating titanium substrates that can handle higher energy densities and longer print cycles without deformation.
DLX vs. Conventional Manufacturing
Compared to generic metal plates, DLX Ti6Al4V substrates maintain superior flatness and microstructural uniformity. Our proprietary finishing process minimizes surface oxidation and provides optimal adhesion for the first layers of powder. This not only reduces print defects but also extends the platform’s usable life — a clear cost advantage for high-volume users.
While some companies treat substrates as consumables, DLX designs them as long-term assets. Our titanium plates can endure hundreds of printing cycles, which reduces downtime and replacement frequency.
Every DLX titanium substrate comes with full traceability, mechanical certification, and dimensional inspection reports. We partner with clients to fine-tune substrate design according to their specific printer setup, ensuring maximum efficiency. Our goal is to help customers produce consistent, high-quality prints — every single time.
The Ti6Al4V Titanium Substrate (Grade 5) by DLX is more than just a printing platform — it’s the foundation for precision and repeatability in modern additive manufacturing. With superior flatness, exceptional strength, and long operational life, it supports advanced 3D printing technologies used across critical industries worldwide.
As the manufacturing world continues to evolve, DLX remains at the forefront of titanium substrate innovation — providing the reliability and performance that define the next generation of metal 3D printing.
