Laser Direct Rapid Prototyping Technology for Metal Parts
Laser direct rapid prototyping technology for metal parts has become an important development area in advanced manufacturing. Compared with traditional prototyping methods, this technology makes it possible to directly build dense metal components with strong mechanical performance and functional value. As a result, it has attracted wide attention from both researchers and industrial manufacturers.
International research on laser direct rapid prototyping for metal parts has covered a range of process routes, including Laser Engineered Net Shaping (LENS), Laser Forming (Lasform), Directed Light Fabrication (DLF), Shape Deposition Manufacturing (SDM), Direct Metal Deposition (DMD), Controlled Metal Buildup (CMB), and Laser Aided Manufacturing Process (LAMP). The wide application and fast development of these technologies demonstrate strong future potential and reflect an important development direction in rapid prototyping.
Main Laser Direct Rapid Prototyping Technologies
LENS
Laser Engineered Net Shaping uses a focused laser beam to melt metal powder as it is deposited, allowing near-net-shape metal parts to be built layer by layer.
Lasform
Laser Forming technology uses laser energy to form metal components directly and is recognized as an important route in metal additive manufacturing research.
DLF
Directed Light Fabrication is another laser-based process that enables direct formation of metal parts through controlled material deposition and laser fusion.
DMD
Direct Metal Deposition is widely studied for building and repairing metal parts by depositing metal material directly into a molten pool created by a laser.
CMB
Controlled Metal Buildup focuses on the precise control of metal deposition during the forming process, helping improve part quality and process stability.
LAMP
Laser Aided Manufacturing Process is also part of the broader development of direct laser metal forming technologies and contributes to the expansion of metal rapid manufacturing applications.
Development of Metal Rapid Prototyping Research
Research on metal laser direct rapid prototyping has also developed along multiple technical routes based on principles such as LENS, DLF, DMD, and SDM. These studies focus on improving forming quality, material density, dimensional accuracy, and the ability to manufacture high-performance functional metal parts.
Among these technologies, laser cladding direct rapid manufacturing is especially important. By combining selective laser sintering concepts with laser cladding technology, it becomes possible to rapidly produce full-density metal components with strong functional performance. This provides clear advantages in applications where structural integrity and material properties are critical.
