Metal laser sintering or laser melting processes can handle a wide range of metals.
These include iron, copper steels, nickel steels, stainless steels, high-strength low-alloy steels, medium- and high-carbon steels, diffusion hardenable steels, brass, bronze, and soft iron magnetic alloys.
These processes are ideal for 3D printing.
They allow for the creation of complex shapes and structures with high accuracy and repeatability.
Metals Suitable for Laser Sintering/Melting
The metals listed are all compatible with metal laser sintering or melting processes.
These materials include iron, various types of steel, brass, bronze, and soft iron magnetic alloys.
They can be sintered by pressing, molding, and injection molding.
These materials are often used in 3D printing to create green parts.
These green parts are then sintered into high-quality, low-porosity parts with excellent properties.
Direct Metal Laser Sintering (DMLS)
This advanced 3D printing technique allows for the direct printing of metal parts using finely powdered metals.
DMLS can combine plastic and metal materials.
This offers versatility in material selection and application.
This method is particularly effective for creating complex metal components with precision.
Liquid Phase Sintering
Although traditionally used for ceramic materials, liquid phase sintering has applications in metal fabrication.
This technique involves the presence of a liquid during the sintering process.
This liquid accelerates molecule densification and inter-particle bonding.
It significantly reduces process time.
Versatility and Environmental Benefits
Metal sintering is versatile in terms of the materials it can process.
It also offers environmental benefits.
It requires less energy than melting the same metal.
This makes it a more environmentally-friendly manufacturing option.
This process allows for greater control over the manufacturing process.
It results in more consistent products.
Industrial Importance
Since the 2010s, metal powder-based additive manufacturing has become a commercially important category of powder metallurgy applications.
This includes selective laser sintering.
This highlights the growing industrial relevance and adoption of metal laser sintering and melting processes.
