2. Material Compatibility: This machine is compatible with a variety of metal powders, including stainless steel, tool steels, and other metal alloys, allowing manufacturers to choose the most suitable material for their specific application. The ability to use different materials also gives manufacturers flexibility in achieving the desired strength, heat resistance, and durability for their molds.
3. High-Quality Metal Mold Production: The DirectTool™ process using the EOSINT™ M 250 Xtended can create metal molds that are highly durable and ready for use in injection molding, casting, and other high-precision manufacturing processes. The molds produced by this equipment are known for their strength, wear resistance, and ability to withstand high temperatures, making them ideal for mass production.

How the DirectTool™ Process Works with EOSINT™ M 250 Xtended

The DirectTool™ process uses SLS technology to build metal molds layer by layer, directly from a CAD design. Here’s how the process works:

1. Digital Design: The process begins with a 3D CAD model of the mold or part. This digital model is then converted into a format that the EOSINT™ M 250 Xtended system can read and use for the production process.
2. Layer-by-Layer Construction: The metal powder is spread across the build platform. A high-powered laser then scans and sinters the powder layer by layer, fusing the metal particles together. This creates a solid object that precisely follows the design data provided by the CAD model.
3. Post-Processing: After the sintering process, the mold may undergo post-processing, which includes heat treatment, machining, or surface finishing. This step ensures that the final mold meets the required specifications for strength, precision, and surface quality.

Advantages of Using the EOSINT™ M 250 Xtended for DirectTool™ Manufacturing

1. Faster Production Time: The DirectTool™ method significantly reduces the time required to produce metal molds compared to traditional methods. The EOSINT™ M 250 Xtended can produce complex metal parts in just a few days, drastically cutting down the time needed for tooling and mold production.
2. High Precision and Complex Geometries: With the EOSINT™ M 250 Xtended system, manufacturers can create highly detailed and complex mold geometries that would be difficult or costly to achieve using traditional mold-making methods. This includes the ability to produce conformal cooling channels and other intricate features that improve mold performance.
3. Cost-Effective Production: By eliminating the need for traditional machining and tooling, the DirectTool™ process using the EOSINT™ M 250 Xtended helps reduce material waste and manufacturing costs. This process also allows for on-demand mold production, reducing the need for large inventories and minimizing storage costs.
4. Enhanced Mold Durability: The molds produced by the DirectTool™ process using EOSINT™ M 250 Xtended are known for their durability and long lifespan. These molds can withstand thousands or even millions of cycles, making them ideal for high-volume production runs.
