Selective laser melting(SLM)/Direct Metal Laser Sintering (DMLS)
Print your SLM/DMLS parts with fast turnaround and wide variety of metal materials as fast as 4-5 days!
Overview: How SLM 3D Printing Works ?
The Basics of SLM 3D Printing
Selective laser melting (SLM), also called Direct Metal Laser Melting (DMLM), is a type of metal additive manufacturing or 3D printing. Often, the terms SLM and Direct Metal Laser Sintering (DMLS) are used interchangeably. SLM Part Strength SLM parts are more robust and denser than investment cast metal parts, and they can help you get to market first with faster turnaround times.
Benefits of SLM 3D Printing
SLM 3D Printing can provide a lightweight solution. Commonly advanced CAD techniques such as topology optimization and generative design are often used for this purpose, resulting in lighter parts (typically 25% to 50%) and higher stiffness. This is the key to high-end applications such as aerospace and other industries.
More complex structures can be formed efficiently. Therefore, some parts that cannot be de-moulded or cut by tools can be manufactured by SLM 3D Printing.
Designs can be made quickly with a minimum of material waste while maximizing strength.
Multiple, identical parts can be built on a single platform at one time, greatly increasing production efficiency.
Benefits of SLM 3D Printing With Unionfab
Unionfab can meet the production of all SLM materials (Stainless Steel, Aluminum Alloy, Maraging steel, Titanium Alloy, Nickel-base Alloy, Copper Alloy) in the market and has rich post-treatment processes (Polishing, Anodizing, Electroplating, Electroless plating, Heat Treatment, Painting, secondary machining, etc.).
Unionfab has four joint factories in South China and East China to cope with the changing market and social situation, with more than 200 imported and domestic printing equipment to meet various samples and batch orders.
we print SLM at a maximum size of 450mm and a minimum wall thickness of 0.3mm, meeting the printing accuracy of ±0.1mm, the secondary processing accuracy of ±0.01mm, and the sample order with the fastest delivery time of 3-4 days.
Conduct 100% full appearance inspection for all products and 2.5% critical dimension inspection for AQL. Provide standard inspection reports, support customers' online quality inspection before shipment, and control the production and inspection of products throughout the process.
Many experienced engineers with solid process capability can assist customers in pre-sales technical support of multi-process and undertake product-level services and orders.
Features of SLM 3D Printing
Difficult to machine parts, custom medical pieces, hollowed or lightweight parts, and artistic pieces fall in this category.
Rapid or continuous revisions
Product development efforts and iterative designs are well-suited to SLM because there are no setup costs as in traditional manufacturing.
Because SLM is a higher temperature process, its printed parts often end up with internal stresses.
SLM machines are designed for high-volume industrial use, so they are expensive.
