Key Characteristics of Metal powder ded SLM DMLS 3d metal printing CoCr CoCrMo CoCrW CoCrMoW Medical Cobalt chromium alloy powder
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of Metal powder ded SLM DMLS 3d metal printing CoCr CoCrMo CoCrW CoCrMoW Medical Cobalt chromium alloy powder
DMLS (Direct Metal Laser Sintering) and SLM (Selective Laser Melting) are 3D printing processes that use metal powders to create complex parts layer by layer. Cobalt-Chromium (CoCr), Cobalt-Chromium-Molybdenum (CoCrMo), Cobalt-Chromium-Tungsten (CoCrW), and Cobalt-Chromium-Molybdenum-Tungsten (CoCrMoW) are biomedical-grade cobalt-chromium alloys commonly used in dental prosthetics, orthopedic implants, and other medical applications due to their biocompatibility, wear resistance, and strength.
Here are some key parameters for these alloys in the context of 3D printing:
1. **Metal Powders:**
– Particle Size: Generally, the powders used have a narrow particle size distribution, typically between 20-63 microns, to ensure uniform melting and better part quality.
– Shape: Mostly spherical or irregular, with a specific surface area (SSA) that affects the bonding during the sintering process.
– Purity: High purity, often above 98%, to minimize impurities that could affect the mechanical properties.
2. **Printing Parameters:**
– Laser Power: Varies depending on the alloy and printer, but generally in the range of 100-400 W for CoCr and up to 500 W for CoCrMo or CoCrW.
– Laser Beam Spot Size: Typically around 50-100 microns to achieve good fusion and resolution.
– Layer Thickness: 10-50 microns, with thinner layers providing higher accuracy but slower print times.
– Infill Density: 10-90% for structural parts, with higher density for stronger components.
3. **Sintering Temperature:**
– CoCr: Around 1100-1200°C
– CoCrMo: 1200-1300°C
– CoCrW: 1250-1350°C
– CoCrMoW: 1300-1400°C
4. **Cooling Rate:**
Rapid cooling is essential to prevent grain growth and maintain high strength.
5. **Post-processing:**
– Heat Treatment (annealing) after printing to improve mechanical properties and reduce internal stresses.
– Surface finishing, such as polishing or coating, may be required for aesthetics and biocompatibility.
6. **Mechanical Properties:**
– Yield Strength: CoCr: ~200 MPa, CoCrMo: ~250-300 MPa, CoCrW: ~350-400 MPa, CoCrMoW: ~400-500 MPa
– Tensile Strength: Similar to yield strength
– Wear Resistance: High due to the presence of carbides in the alloy.
7. **Biological Compatibility:**
– All cobalt-chromium alloys mentioned are considered biocompatible, but some surface treatments might be necessary for optimal tissue response.
Please note that specific parameters may vary depending on the manufacturer’s recommendations and the exact 3D printer model being used. Always consult the manufacturer’s guidelines for optimal settings and performance.
