In aerospace manufacturing, complexity is a given. Components must deliver reduced weight, high structural performance, and efficient geometries while meeting strict reliability standards. This propulsion adapter, designed by Meltio, illustrates how advanced metal additive manufacturing is expanding what can be achieved with challenging materials such as titanium when paired with the right expertise.
Building on its established experience printing titanium components, Fastech has applied this expertise to the Meltio Blue Laser M600 and Meltio Robot Cell to demonstrate the system’s full manufacturing potential. Produced using Meltio’s wire-laser metal deposition technology, this Titanium 64 propulsion adapter was developed by the Meltio team as a technology showcase to highlight two key capabilities of the platform: the stable processing of reactive, aerospace-grade titanium using Blue Laser technology, and the ability to manufacture complex, near-net-shape geometries with high material efficiency in a fully inert environment. As the first Meltio reference center in the United States, Fastech demonstrates how this platform enables the production of high-value, structurally critical aerospace components that would be difficult, time-consuming, or cost-prohibitive to manufacture using conventional methods.
Propulsion Adapter
A Component Designed to Challenge Manufacturing Limits
The propulsion adapter is intended to connect the wing structure to the main fuselage of an unmanned aerial vehicle. This type of aerospace application demands high mechanical strength, excellent material integrity, and precise dimensional control. The part’s geometry includes internal cavities, varying wall thicknesses, and load-bearing features that traditionally require complex multi-step machining processes.
By leveraging additive manufacturing, the component can be produced as a near-net-shape part in a single build. This approach reduces material waste, shortens lead times, and enables design freedom that supports performance-driven engineering rather than manufacturing compromise.
Printing Titanium with Confidence
Titanium 64 is widely used in aerospace for its exceptional strength-to-weight ratio and corrosion resistance, but it is also notoriously challenging to process. Meltio’s wire-based deposition approach addresses many of these challenges. Using titanium wire rather than powder improves material efficiency, enhances safety, and ensures consistent chemistry throughout the build.
For this demonstration, the part was printed on a Meltio M600 using an inert argon atmosphere with full inertization, a critical requirement when working with reactive materials such as titanium. The build envelope measured approximately 257 x 400 x 200 mm, resulting in a finished weight of 4.27 kg. A layer height of 1.2 mm was selected to balance deposition efficiency with geometric resolution.
The system operated with Meltio’s blue laser technology, running at power levels of 1.0 kW to 1.4 kW, with total build times ranging from just over 9 hours to approximately 12.5 hours depending on parameters. These settings highlight how the M600 can be tuned for productivity while maintaining excellent metallurgical quality.

The Advantage of Blue Laser Technology
Blue laser technology represents a significant advancement in metal additive manufacturing. Compared to infrared lasers, blue lasers offer higher absorption rates in reflective materials such as titanium, copper, and aluminum. This improved energy coupling results in a more stable melt pool, better process control, and consistent deposition quality.
For manufacturers, this means greater confidence when scaling production or qualifying parts for end-use applications. It also opens the door to printing a wider range of materials on a single platform, increasing flexibility across industries such as aerospace, defense, and naval manufacturing.
Unlocking New Manufacturing Potential
This propulsion adapter demonstrates more than just a single component. It represents the broader potential of the Meltio M600 as a manufacturing tool. The system supports a wide range of materials beyond titanium, including stainless steels, tool steels, Inconel, and copper alloys. Its ability to print, repair, and add features to existing components makes it equally valuable for prototyping, production, and maintenance operations.
At Fastech, this capability aligns with a deep expertise in advanced manufacturing and automation. As a Meltio reference site, Fastech is positioned to help manufacturers explore how wire-laser metal deposition can be integrated into real-world production environments, delivering performance, efficiency, and design freedom that traditional methods struggle to match.
This titanium propulsion adapter is a glimpse into what modern metal additive manufacturing can achieve when technology, material science, and manufacturing expertise come together.
