FAQ

AO Metal is a USA-designed and assembled manufacturer of open-process LPBF metal 3D printers built specifically for research labs, universities, startups, and additive manufacturing teams. The company focuses on accessible and customizable metal additive manufacturing systems that give users full control over process parameters while supporting advanced materials research and production.

LPBF stands for Laser Powder Bed Fusion, an advanced metal additive manufacturing process that uses a high-powered laser to selectively melt layers of metal powder and create highly detailed metal components layer by layer.

Most industrial LPBF systems are designed for factory-scale production with locked parameters, proprietary workflows, and high equipment costs. AO Metal takes a different approach by providing compact, lab-ready systems with fully open process control, allowing users to optimize laser power, scan strategies, thermal management, and other key process variables without vendor restrictions.

Materials research depends on experimentation and process optimization. Open parameter access allows research teams to adjust laser settings, thermal conditions, hatch spacing, and scan strategies to better understand material behavior and improve mechanical properties and print quality.

AO Metal printers are designed for universities, research laboratories, additive manufacturing service providers, aerospace organizations, startups, innovation centers, and corporate R&D teams looking for flexible and accessible LPBF metal 3D printing solutions.

AO Metal printers support a broad range of materials including stainless steels, tool steels, titanium alloys, aluminum alloys, copper alloys, gold, silver, refractory metals, intermetallics, high-temperature superalloys, and reactive materials depending on the selected configuration.

Yes. AO Metal systems support titanium alloys commonly used in aerospace, automotive, defense, and advanced engineering applications where high strength-to-weight ratios and corrosion resistance are critical.

Yes. AO Metal printers support multiple stainless steel grades suitable for research, tooling, prototyping, and production applications requiring durability and corrosion resistance.

Yes. AO Metal systems can process aluminum alloys used in lightweight engineering, aerospace, automotive, and prototyping applications where reduced weight and high performance are important.

Yes. AO Metal’s optional blue laser technology on the A50 and A100 significantly improves copper processing by increasing laser absorption and enabling cleaner and more stable melting.

Copper is highly reflective to traditional infrared laser wavelengths, making it difficult to absorb enough energy for stable melting. This often results in inconsistent prints and poor process stability on conventional systems.

Blue laser technology uses approximately 450 nm wavelength lasers that are absorbed far more efficiently by reflective metals such as copper, gold, and silver compared to standard infrared lasers.

Optional blue laser configurations are available on the AO Metal A50 and A100 systems for advanced materials development and reflective metal applications.

Blue laser technology improves energy absorption, melt stability, and print quality for reflective metals. This makes it especially valuable for copper components, precious metals, RF systems, waveguides, EV thermal applications, and advanced electronics manufacturing.

Yes. AO Metal systems with blue laser capability are well suited for processing precious metals such as gold and silver, making them ideal for jewelry manufacturing, advanced prototyping, and research applications.

Industries including aerospace, electronics, EV manufacturing, thermal management, RF systems, waveguide manufacturing, and jewelry production benefit from blue laser metal 3D printing because of its improved performance with reflective metals.

Inductive volumetric preheat is a heating technology that heats the entire build chamber rather than only the build plate. This creates a more thermally stable environment for printing difficult materials.

The AO Metal A50 and A100 systems support inductive volumetric preheat temperatures up to 900°C for advanced material processing.

High-temperature preheating reduces thermal stress, minimizes cracking, and improves thermal consistency during printing. This is especially important when processing refractory metals, intermetallics, and crack-prone superalloys.

Yes. AO Metal systems equipped with 900°C inductive volumetric preheat can process refractory metals such as tungsten and molybdenum more effectively than conventional room-temperature LPBF systems.

Refractory metals are extremely heat-resistant materials with very high melting points that are commonly used in aerospace, defense, energy, and high-performance engineering applications.

Yes. AO Metal systems support advanced materials development involving intermetallic compounds such as TiAl and NiAl that require precise thermal management.

Intermetallics are engineered metallic compounds designed for high-temperature strength, lightweight performance, and advanced aerospace and industrial applications.

Yes. AO Metal systems support high-temperature superalloys including IN738, René 80, and CM247, which are commonly used in aerospace and energy applications.

Superalloys are highly sensitive to thermal stress and often develop cracks during cooling. Controlled chamber heating and thermal management help reduce crack formation and improve print quality.
