Direct Metal Laser Sintering (DMLS) for High-Performance Parts
Direct Metal Laser Sintering (DMLS), often interchangeable with Selective Laser Melting (SLM), represents the pinnacle of additive manufacturing. Unlike polymer printing, DMLS utilizes high-power fiber lasers to fully melt fine metal powders layer by layer, creating solid, fully dense metal components.
At JUCHENG, we unlock the ability to manufacture "impossible geometries." From internal conformal cooling channels in injection molds to topology-optimized aerospace brackets that reduce weight by 50%, our industrial DMLS systems deliver parts that traditional CNC machining or casting simply cannot produce. We provide a complete metal AM solution, including printing, heat treatment, and precision CNC post-processing, ensuring your parts meet the rigorous standards of the aerospace, medical, and automotive industries.
DMLS / SLM Metal 3D Printing

JUCHENG’s Metal Additive Manufacturing Capacity

Metal printing is a complex process requiring strict metallurgical control. Our capabilities include:
  • High-Density Fusion: We optimize laser parameters to achieve 99.8%+ part density, delivering mechanical properties comparable to (and sometimes exceeding) wrought materials.
  • Hybrid Manufacturing: DMLS parts often require tight tolerances on bearing surfaces. We combine 3D printing with 5-Axis CNC Machining to finish critical features to ±0.01mm.
  • Thermal Processing: We perform in-house Stress Relief and Heat Treatment (Aging/Annealing) to remove internal residual stresses and optimize the microstructure of alloys like Titanium and Inconel.
  • Support Removal: We utilize wire EDM and manual finishing to remove the rigid metal support structures required during the printing process.

Comparison

Comparison: DMLS vs. CNC Machining vs. Metal Casting
When should you print metal instead of cutting or casting it?
Feature DMLS / SLM (3D Printing) CNC Machining Metal Casting
Geometry Freedom Unlimited (Internal channels, lattices) Limited (Tool access required) Medium (Draft angles required)
Material Waste Low (Recyclable powder) High (Subtractive) Medium (Sprues/Runners)
Tooling Cost Zero Low (Fixtures) High (Molds)
Lead Time Fast (Days) Medium (Weeks) Slow (Months)
Surface Finish Matte / Rough (Ra 3.2-6.3) SmallMedium (Weeks) Good to Rough
Best For Complex, lightweight, low volume Precision, flat surfaces, all volumes High volume, simple shapes

Why Choose Us

The JUCHENG DMLS AdvantageThe JUCHENG FDM Advantage
  • Metallurgy Experts: We don't just push a button. Our engineers adjust laser power, hatch distance, and layer thickness to ensure the metallurgical integrity of your specific alloy.
  • Post-Processing Power: Raw DMLS parts are rarely "ready-to-use." With our in-house CNC shop, grinding, and polishing capabilities, we deliver finished precision components, not just rough blanks.
  • Quality Verification: We offer density reports, material composition analysis (COA), and CT scanning services to verify internal integrity for critical aerospace parts.

Advantages

Why Switch to Metal 3D Printing?
  • Part Consolidation: Combine an assembly of 10 machined parts into 1 single printed unit, reducing assembly time and leak points.
  • Weight Reduction: Use internal lattice structures to reduce weight by up to 60% while maintaining structural rigidity—critical for aerospace.
  • Thermal Management: Create conformal cooling channels that hug the surface of the part, drastically improving heat dissipation in molds or engines.

Industries Served

Industries Driven by Metal AM
  • Aerospace: Fuel nozzles, turbine blades, lightweight structural clips, satellite components.
  • Medical: Customized orthopedic implants (hips/knees), surgical guides, dental copings.
  • Automotive: Formula 1 cooling ducts, turbocharger components, rapid prototyping of cast parts.
  • Tooling: Conformal cooling inserts for plastic injection molding (reducing cycle time).
  • Energy: Impellers and diffusers for oil & gas drilling equipment.
