FasTech LLC
Based in Danville Virginia, FasTech LLC was established in 2018 to provide cutting edge metal additive 3D printing, using the first Gefertec 5-axis 3D metal printing system in the U.S. In 2022, FasTech also invested in an additional Gefertec 3 & 5-axis 3D metal printing system along with a Meltio laser wire-DED system to print components that have finer details. Five years on, we now also have a range of state-of-the-art machining centers to complete the production process on site, plus the latest equipment for inspection and reverse engineering. With the ability to offer standalone or combined rapid machining and additive 3D metal printing capabilities, FasTech’s prototyping, design for manufacturing, and supply management services allow for reduced lead times (up to ten times compared to traditional manufacturing to meet challenging timelines), reduction in manufacturing costs (due to 100% material (welding wire) utilization), easy sourcing and handling, and storage of base materials. FasTech is an active indirect supplier to the US Navy of additively manufactured production parts, they are currently the Alpha partner for the AMPro Submarine program where they develop all printing parameters and processes to be used within the US Navy’s Additive Center of Excellence in Danville Virginia.

Small to Large Scale Metal Additive Manufacturing using Wire-DED
Problem:
It is challenging to produce large-scale metal components using 3D-printing. Laser powder-bed fusion (L-PBF) technologies can create small-scale complex geometries and have achieved high TRL and MRL levels. However, there is a significant gap in producing large-scale metal components that can be readily applied in real-life applications. Fastech, as a contract manufacturer, provides solutions to manufacture small to large and low to medium complex components using WAAM and LW-DED processes.
Technology Solution:
We utilize wire-DED processes for manufacturing components. In wire-DED, wire serves as the feedstock, while an electric arc or laser functions as the energy source. When an electric arc is used, it is referred to as wire arc additive manufacturing (WAAM), and when a laser is employed, it is known as laser-wire directed energy deposition (LW-DED). We can print components in various materials like Ti64, nickel, and steel. Additionally, we have finishing machining and metrology capabilities to complement our AM.
Benefits:
- Reduction in lead times.
- Mitigate supply chain issues.
- Lower manufacturing cost.
- Reduce transportation problems.
