EOS MaragingSteel MS1 DMSL on EOS M 300-4 Product Information -:- For detailed product information, please contact sales. -: # EOS MaragingSteel MS1 ## DMSL on EOS M 300-4 Quad-Laser System --- ### **Product Overview** **EOS MaragingSteel MS1** is a premium gas-atomized maraging steel powder engineered for high-throughput, industrial additive manufacturing. When processed on the **EOS M 300-4**—a **quad-laser Direct Metal Selective Laser Melting (DMSL)** system—it enables the **large-scale, serial production** of ultra-high-strength, complex steel components. This machine-material combination represents the **pinnacle of productivity for maraging steel AM**, leveraging four synchronized 400W lasers to drastically reduce build times while maintaining the exceptional mechanical properties (>1950 MPa UTS) characteristic of precipitation-hardened MS1. It is designed for **factory-floor production** of end-use parts and tooling where volume, consistency, and cost-per-part are critical. --- ### **Chemical Composition (Weight %) - Production-Grade Powder** | Element | EOS MS1 Specification | Criticality for M 300-4 Process | |---------|----------------------|--------------------------------| | **Nickel (Ni)** | 17.0 - 19.0 | Consistent matrix formation across large, multi-laser build area. | | **Cobalt (Co)** | 8.5 - 9.5 | Uniform aging response in parts from different laser zones. | | **Molybdenum (Mo)** | 4.5 - 5.2 | Primary hardening element; must be homogeneously distributed in powder. | | **Titanium (Ti)** | 0.6 - 0.8 | Optimized for minimal oxidation during multi-laser processing. | | **Aluminum (Al)** | ≤ 0.10 | Tight control ensures consistent powder flow across large recoater. | | **Carbon (C)** | ≤ 0.03 | Low carbon prevents hot cracking in high-stress, multi-laser builds. | | **Oxygen (O)** | **≤ 0.08% (800 ppm)** | **Even stricter control** vs. single-laser systems to prevent inconsistency between laser fields. | | **Nitrogen (N)** | ≤ 0.04% | Controlled to prevent nitride formation in high-temperature zones. | | **Iron (Fe)** | Balance | Base. | **Powder Specifications for M 300-4:** * **Particle Size Distribution:** **20 - 63 µm** (optimized for high-speed recoating). * **Morphology:** High sphericity (>95%), gas-atomized. * **Flowability:** Hall Flow < 28 s/50g (superior flow required for large-area spreading). * **Batch Consistency:** Extreme lot-to-lot consistency mandatory to ensure identical behavior under all four lasers. * **Packaging:** Bulk containers (e.g., 200 kg) for continuous production. --- ### **EOS M 300-4 System & Quad-Laser Process** **System Configuration:** * **Lasers:** **4 x IPG Yb-fibre lasers, each 400 W**. * **Beam Delivery:** **Independent scanner system per laser** (F-Theta lenses). * **Build Volume:** **300 x 300 x 400 mm** (industry-standard large format). * **Atmosphere:** High-flow **Argon** with multi-point O₂ monitoring (< 0.1%). * **Layer Thickness:** **40 µm** (standard production), 60 µm (high-rate), 30 µm (high detail). * **Recoater:** High-speed, vibration-assisted blade for uniform powder deposition across full bed. **Build Strategy & Laser Management:** * **Field Partitioning:** Build platform is dynamically divided into **optimized zones** for each laser, minimizing idle time. * **Scan Strategy:** **Island-based or Stripes** with pseudo-random offset to eliminate stitch-line artifacts at zone boundaries. * **Overlap Management:** Precise calibration ensures seamless fusion at **laser field borders** (typical overlap 100-200 µm). * **Parameter Set:** **EOS "Performance" Parameters** for MS1, optimized for multi-laser stability and high build rates (≈ 25-40 cm³/hr total volumetric rate). **Key Multi-Laser Advantages:** * **Build Time Reduction:** Up to **4x faster** than single-laser M 290 for full-bed builds. * **Thermal Management:** Distributed heat input reduces residual stress gradients in large parts. * **Redundancy:** If one laser fails, the build can often continue at reduced rate. --- ### **Post-Processing Heat Treatment** *Identical to single-laser process, but stress relief is more critical due to larger part sizes.* 1. **Stress Relief (Highly Recommended):** 650°C for 2-4 hours (scale with part mass). 2. **Solution Annealing:** 820°C for 1h + 1h/100mm, vacuum/argon, furnace cool. 3. **Aging:** 490°C for 6 hours, air cool. --- ### **Mechanical Properties (After Full HT - Multi-Laser Production)** *Properties are consistent across laser zones when process is optimized.
