Technical Capabilities
Technical Specifications for 3D Printing Technologies in China – Focus on SLA, SLS, MJF, and DMLS
China has become a major hub for advanced 3D printing services, offering high-precision manufacturing across key additive technologies. Below is a comparative overview of Stereolithography (SLA), Selective Laser Sintering (SLS), Multi Jet Fusion (MJF), and Direct Metal Laser Sintering (DMLS), including their technical capabilities and compatible materials such as Aluminum, Steel, ABS-like polymers, and Nylon.
| Technology | Process Description | Build Volume (Typical) | Layer Resolution (Typical) | Surface Finish | Common Materials Available in China | Mechanical Properties | Key Applications |
|---|---|---|---|---|---|---|---|
| SLA (Stereolithography) | Photopolymerization using UV laser on liquid resin | 145 x 145 x 185 mm to 1500 x 750 x 500 mm (industrial) | 25–100 µm | Smooth, high detail | Standard resins, Tough/ABS-like resins, Castable, Dental, High-temp | Low to medium strength, brittle compared to thermoplastics | Prototypes, master patterns, dental models, visual models |
| SLS (Selective Laser Sintering) | CO₂ laser fuses powdered nylon-based materials | 250 x 250 x 300 mm to 700 x 380 x 580 mm | 80–120 µm | Slightly grainy, good detail | Nylon 11, Nylon 12, Glass-filled Nylon, TPU (limited) | High strength, good impact resistance, flexible options | Functional prototypes, end-use parts, jigs & fixtures |
| MJF (Multi Jet Fusion) | Thermal fusing of powder with inkjet-applied agents | 380 x 280 x 380 mm | 80–100 µm | Smooth, slightly textured, consistent | Nylon 12, Glass-filled Nylon, TPU (expanding) | Excellent mechanical properties, isotropic behavior | End-use parts, complex housings, automotive, consumer goods |
| DMLS (Direct Metal Laser Sintering) | High-power laser fuses metal powder layer by layer | 250 x 250 x 325 mm to 400 x 400 x 400 mm | 20–50 µm | Rough as-printed, requires post-processing | Stainless Steel (316L, 17-4 PH), Aluminum (AlSi10Mg), Titanium, Inconel, Tool Steel | High strength, excellent thermal and fatigue resistance | Aerospace, medical implants, tooling, high-performance components |
Notes on Materials:
ABS-like (SLA/SLS): While true ABS is not printable via SLA or SLS, engineering-grade resins and nylons simulate ABS properties in terms of strength, stiffness, and thermal resistance.
Nylon (SLS/MJF): Nylon 12 is most common; offers excellent durability, chemical resistance, and is suitable for mechanical parts. MJF provides faster throughput and more consistent mechanical properties than SLS.
Aluminum (DMLS): AlSi10Mg is widely used in China for lightweight, high-strength components requiring good thermal and corrosion resistance.
Steel (DMLS): Stainless steels (e.g., 316L, 17-4 PH) are standard for industrial and medical applications, offering high hardness, corrosion resistance, and suitability for post-machining.
Manufacturers and service bureaus in China, particularly in Shenzhen, Dongguan, and Shanghai, offer these technologies with ISO-compliant quality control, fast turnaround, and competitive pricing, making them a strategic choice for global prototyping and low-volume production.
From CAD to Part: The Process
Honyo Prototype delivers end-to-end 3D printing services with manufacturing operations based in China, leveraging advanced infrastructure and engineering expertise to provide rapid, high-quality prototypes and low-volume production parts globally. Our standardized workflow ensures technical rigor and client transparency at every stage. Below is a detailed explanation of our core process:
Upload CAD
Clients initiate the process by uploading native CAD files (STEP, IGES, Parasolid) or mesh formats (STL, 3MF) via our secure customer portal. Our system performs an initial validation check for file integrity, watertight geometry, and minimum feature resolution. We explicitly reject non-manufacturable geometries (e.g., zero-thickness walls, intersecting surfaces) at this stage to prevent downstream delays. Clients receive immediate confirmation of upload success or actionable feedback for file correction.
AI-Powered Quoting Engine
Uploaded designs enter our proprietary AI quoting system, which analyzes over 200 geometric and material parameters within 90 seconds. Unlike basic cost calculators, this engine cross-references real-time production constraints including build volume optimization, support structure requirements, and anisotropic strength considerations. The generated quote includes not only pricing and lead time but also preliminary manufacturability flags such as recommended orientation for critical tolerances or potential stress concentrations. Clients can request manual engineering review at this stage for complex assemblies.
Engineering-Validated DFM
All projects undergo mandatory Design for Manufacturing review by our in-house engineering team in Shenzhen. This phase extends beyond automated checks to address application-specific requirements:
Material suitability analysis against functional needs (e.g., ULTEM 9085 for aerospace flame resistance)
Tolerance validation per ISO 2768-mK standards with deviation reporting
Support structure optimization to minimize post-processing artifacts
Wall thickness and overhang correction per material-specific thresholds
Clients receive a formal DFM report within 4 business hours, highlighting resolved issues and actionable suggestions for design refinement. No part proceeds to production without client sign-off on the DFM findings.
Production Execution
Approved designs move to our Shenzhen manufacturing campus equipped with industrial-grade systems across key technologies:
| Technology | Primary Materials | Build Volume (Max) | Layer Resolution | Key Applications |
|---|---|---|---|---|
| SLS | PA11, PA12, TPU | 700 x 380 x 580 mm | 0.08 – 0.15 mm | Functional assemblies, ducts |
| MJF | PA12, PA11 | 380 x 284 x 380 mm | 0.08 mm | High-detail enclosures |
| SLA | Standard, Engineering, Dental resins | 140 x 140 x 175 mm | 0.025 – 0.1 mm | Clear optics, medical models |
| Metal DMLS | Ti6Al4V, AlSi10Mg, Inconel 718 | 250 x 250 x 325 mm | 0.02 – 0.05 mm | Aerospace brackets, implants |
Production batches are tracked via IoT-enabled machines with real-time monitoring of temperature, humidity, and laser calibration. First-article inspection reports (FAIR) are generated for all critical dimensions using calibrated CMM equipment.
Global Delivery Protocol
Finished parts undergo multi-stage quality verification:
1. In-process dimensional checks at 25%/75% build completion
2. Final inspection against client-specified GD&T callouts
3. Material certification traceability documentation
All shipments include serialized tracking, climate-controlled packaging for sensitive resins, and customs documentation pre-validated for major markets (EU, US, APAC). Standard lead time from DFM approval to door is 3-7 business days, with expedited options available. Clients receive automated logistics updates with delivery confirmation and post-shipment technical support access.
This integrated process ensures that China-based manufacturing delivers Western engineering standards through systematic technical validation at each transition point, eliminating common offshore production risks while maintaining cost efficiency.
