Laser Additive Manufacturing
What is Laser Additive Manufacturing?
Encompassing a variety of processes, including selective laser melting and sintering, laser metal fusion, and laser metal deposition, laser additive manufacturing (LAM) is a flexible, high-speed process suited for both prototyping and industrial production. Laser additive manufacturing solutions offer high-quality results in a wide variety of materials including aluminum, steels, copper, and polymers and other non-metals.
Highly precise spatial control of the laser beam enables the creation of both fine and bulk features with resolutions that reduces the need for finishing processes, even in complex parts. Optimization of laser parameters such as focus and wavelength combined with high-speed scanning of the beam enables the rapid creation of both full parts and additive features.

Laser Additive Manufacturing Capabilities
Fine tuning of laser parameters allows for optimization of laser additive manufacturing processes. Adjustments in laser focus, wavelength, power, and pulse properties enables higher process speeds and quality across materials, features, and geometries.
Copper manufacturing, for example, often utilizes green lasers to take advantage of the green wavelength's favorable interaction with the material. In many copper applications, however, highly focused infrared lasers deliver similar results.
Dual-Mode Fiber Lasers for High-Speed Additive Manufacturing
Developed specifically for 3D metal printing, dual-mode fiber lasers combine independently adjustable single-mode and multi-mode outputs into one fiber to offer up to 5X higher printing speeds.
Compared to alternative solutions like external moving bulk optics or other mode switching technologies, dual-mode fiber lasers are more compact and cost-effective and are not sensitive to alignment, vibration, or contamination.

Selective Laser Sintering
Selective Laser Sintering (SLS) and the closely related Selective Laser Melting (SLM) fuse or melt layers of powder to produce parts with excellent mechanical properties. SLS and SLM work well with a variety of materials and for complex part geometries.
Laser Metal Deposition
Laser Metal Deposition (LMD), also know as laser cladding, uses metal powder fed co-axially through a nozzle to add material to an existing workpiece. The process produces high quality features with minimal thermal impact on the underlying part.
Stereolithography
Stereolithography (SLA) is a common resin 3D printing method that builds parts layer by layer. This photochemical process is a fast and cost-effective approach for creating prototypes for medical device manufacturers and a variety of other industries.
