3D Printing & Additive Manufacturing Division

Industrial SLA, SLS, and Direct Metal Laser Sintering (DMLS) in 24–48 Hours.

The 3D Printing & Additive Manufacturing Division enables rapid design verification without tooling costs or machining constraints. With industrial-grade Direct Metal Laser Sintering (DMLS), Selective Laser Sintering (SLS), and Stereolithography (SLA) systems, we print fully dense titanium, stainless steel, and nylon components ready for immediate functional bench testing.

Direct Metal Laser Sintering (DMLS) in Titanium & Steel

Fully Dense Aerospace Hardware with Internal Fluidic Channels

Direct Metal Laser Sintering (DMLS / SLM) enables internal organic cooling channels, lattice structures, and topology-optimized aerospace brackets impossible to machine with traditional subtractive CNC mills. Using high-power ytterbium fiber lasers fusing micronized metal powders in an argon inert chamber, our metal printers produce components with 99.8% metallurgical density equivalent to wrought alloys.

Key Engineering Takeaways
  • Titanium Ti-6Al-4V, Stainless Steel 316L, and Inconel 718 functional additive alloys
  • Weight reduction up to 60% through generative design and internal honeycombs
  • Stress-relief vacuum annealing heat treatment applied to all metal prints
ARTICLE 02 Selective Laser Sintering (SLS) Nylon PA12 Functional Prototypes

Selective Laser Sintering (SLS) Nylon PA12 Functional Prototypes

Tooling-Free Production with Isotropic Strength and Snap-Fit Durability

Selective Laser Sintering (SLS) uses a CO2 laser to fuse powdered engineering thermoplastics layer by layer. Because unsintered powder supports the part during the print build, SLS requires zero support structures, allowing complex nested assemblies, living hinges, and internal ductwork to be printed in Nylon PA12 and glass-bead reinforced PA12 with high mechanical resilience.

Key Engineering Takeaways
  • High mechanical tensile strength (48 MPa) and excellent chemical resistance
  • Vapor smoothing and deep black dyeing post-processing producing production-grade look and feel
  • Capable of printing functional living hinges, snap-fits, and complex air ducting
ARTICLE 03 Stereolithography (SLA) for Ultra-Smooth Cosmetic Models

Stereolithography (SLA) for Ultra-Smooth Cosmetic Models

Sub-0.05mm Layer Resolution for Ergonomic Studies and Clear Optics

For industrial design reviews, investor pitches, and optical validation, Stereolithography (SLA) provides the finest surface finish of any additive technology. Ultraviolet lasers cure liquid photopolymer resins into glass-smooth components with layer lines invisible to the naked eye. We also print optical-clear resins hand-polished to transparent acrylic clarity.

Key Engineering Takeaways
  • Crisp feature reproduction capturing micro-text, knurling, and razor-sharp logos
  • ABS-like and high-temperature resins with heat deflection up to 90°C
  • Optical clear resin polished to transparent water-clear finishes for light pipes and lenses

Merging Additive Geometric Freedom with Sub-Micron CNC Tolerances

While metal 3D printing provides infinite geometric freedom, printed tolerances are typically ±0.1mm. JYH bridges this through hybrid manufacturing: we print oversized stock on mating interfaces, then transfer the additive part directly to our 5-axis CNC machining centers to mill O-ring sealing faces, ream bearing bores, and thread tapped holes to ±0.005mm.

Key Engineering Takeaways
  • Best of both worlds: internal complex fluid passages with sub-micron mating surfaces
  • Custom datum locating features printed directly onto the workpiece for precision CNC alignment
  • Zeiss CMM inspection validating both additive core geometry and CNC machined tolerances
