Technical Capabilities

The requested technologies—SLA, SLS, MJF, and DMLS—are commonly used in advanced additive manufacturing. However, it is important to clarify that Stereolithography (SLA) and Multi Jet Fusion (MJF) are primarily polymer-based processes and are not typically used for metal 3D printing. Selective Laser Sintering (SLS) is also mainly employed for nylon and other thermoplastics, though metal variants exist in research or hybrid systems. Direct Metal Laser Sintering (DMLS) is the only fully established metal additive manufacturing process among the four.
Below is a technical specification table outlining the capabilities and material compatibility for each process, with accurate alignment to industry standards:
| Process | Technology Type | Primary Materials | Compatible Metals | Compatible Polymers | Layer Resolution Range | Build Volume (Typical Max) | Surface Finish (Ra) | Key Applications |
|---|---|---|---|---|---|---|---|---|
| SLA (Stereolithography) | Photopolymerization | Photopolymer resins | Not applicable | ABS-like, Tough, Flexible, Castable resins | 25–100 μm | 1450 x 800 x 500 mm (large format) | 0.8–2.0 μm | Prototyping, molds, visual models |
| SLS (Selective Laser Sintering) | Powder Bed Fusion (Polymer) | Nylon (PA11, PA12), Glass-filled Nylon | Not standard | Nylon (PA11, PA12), TPU | 80–120 μm | 700 x 380 x 580 mm | 10–20 μm (as-printed) | Functional prototypes, end-use parts, complex geometries |
| MJF (Multi Jet Fusion) | Powder Bed Fusion (Polymer) | PA12, PA11, TPU | Not applicable | ABS-like (HP proprietary), Nylon (PA12), TPU | 80–100 μm | 380 x 280 x 380 mm | 5–15 μm (as-printed) | High-volume end-use parts, mechanical components |
| DMLS (Direct Metal Laser Sintering) | Powder Bed Fusion (Metal) | Metal alloys | Aluminum (AlSi10Mg, AlSi7Mg), Stainless Steel (17-4 PH, 316L), Tool Steel (Maraging), Titanium (Ti6Al4V) | Not applicable | 20–50 μm | 250 x 250 x 325 mm (typical) | 10–25 μm (as-printed), improved with post-processing | Aerospace, medical implants, tooling, high-stress components |
Notes:
SLA does not support metal printing; it is exclusively for photopolymer resins, including engineering-grade materials that simulate ABS properties.
SLS and MJF are polymer-centric technologies. While metal-infused powders or hybrid post-processing (e.g., infiltration) exist, they do not achieve full-density metal parts like DMLS.
DMLS is the preferred method for producing fully dense, high-strength metal components from aluminum, steel, and titanium alloys.
Materials such as ABS are not directly printable via SLS or MJF in standard forms but are emulated through nylon-based composites with similar mechanical behavior.
For metal 3D printing services, DMLS remains the industry-standard solution for functional, load-bearing metal components. SLS, MJF, and SLA serve critical roles in polymer additive manufacturing and are often used in parallel for non-metal prototypes, jigs, and fixtures.
From CAD to Part: The Process

Honyo Prototype Metal 3D Printing Service Workflow
Our end-to-end metal additive manufacturing process is engineered for precision, efficiency, and technical rigor. Below is a detailed explanation of each phase, reflecting our commitment to industrial-grade outcomes and seamless B2B integration.
CAD File Submission
Clients initiate the process by uploading native CAD files via our secure customer portal. We exclusively accept industry-standard formats including STEP AP203/214, IGES, and Parasolid (.x_t, .x_b). STL files are accepted only when accompanied by the original parametric CAD model to ensure geometric integrity. File validation checks for watertight geometry, minimum feature resolution (≥0.4mm), and adherence to build envelope constraints (max 500 x 500 x 500mm for SLM systems). Incomplete or non-compliant files trigger automated notifications with specific failure diagnostics before proceeding.
AI-Powered Quoting Engine
Upon file validation, our proprietary AI engine generates a preliminary quote within 90 minutes. This system analyzes 37 distinct parameters: bounding box volume, support structure density, layer thickness requirements, material utilization efficiency, and machine-specific build time algorithms. Quotes include material cost (based on real-time powder market rates for Inconel 718, Ti-6Al-4V, AlSi10Mg, etc.), post-processing labor estimates, and geometric complexity surcharges. Critical tolerances specified in the CAD model (e.g., ±0.1mm on critical datums) automatically adjust pricing tiers. Clients receive a downloadable PDF report detailing all cost variables.
Engineering-Led DFM Analysis
All projects undergo mandatory Design for Metal Additive (DFM) review by our ASQ-certified manufacturing engineers. This phase combines automated simulation (using Materialise Magics and ANSYS Additive Prep) with human expertise to address:
Support structure optimization for thermal stress mitigation
Build orientation analysis to minimize residual stress (via finite element modeling)
Critical surface identification requiring post-machining
Powder evacuation channel validation for internal cavities
Heat treatment requirements based on material and geometry
Clients receive a formal DFM report with actionable recommendations, including risk assessments for features below 0.5mm thickness or overhangs exceeding 45°. Revisions are collaboratively managed via the portal with version-controlled CAD markups.
Production Execution
Approved designs enter our certified production environment operating under ISO 9001:2015 and NADCAP standards. Key production stages include:
Machine calibration: Laser power verification (±2W tolerance) and build plate leveling (±5μm flatness)
Build process: Layer-by-layer fabrication using 20-50μm layer thickness on EOS M 400-4 or SLM Solutions SLM®500 systems with inert argon atmosphere (O₂ < 100ppm)
In-situ monitoring: Coaxial melt pool sensors and thermal imaging capture 1,200+ data points per layer
Post-processing: Stress relief annealing, support removal via wire EDM, HIP (if specified), and precision machining per AS9100-compliant work instructions
Quality-Controlled Delivery
Final parts undergo stringent verification before shipment:
Dimensional inspection: CMM validation against original CAD (report includes GD&T analysis per ASME Y14.5)
Material certification: Full traceability from powder lot to finished part with test coupons meeting AMS 7000 standards
Surface finish validation: Ra measurements via profilometry (typical as-built Ra 8-12μm)
Non-destructive testing: X-ray CT scanning for internal defects (per ASTM E1000) when specified
All deliverables include a comprehensive quality package: first article inspection report (FAIR), material test report (MTR), and process parameter log. Parts ship in anti-static, humidity-controlled packaging with real-time GPS tracking. Typical lead time from DFM approval to delivery is 7-12 business days for standard builds.
