This proprietary platform delivers accurate, detailed manufacturing quotations for metal AM parts within minutes, based on your uploaded 3D CAD file and technical requirements, eliminating traditional procurement delays and enabling rapid design iteration and production planning. Experience the precision and efficiency of industrial-scale metal additive manufacturing with Honyo Prototype’s certified production ecosystem.
Technical Capabilities
Metal additive printing technologies such as Direct Metal Laser Sintering (DMLS) are commonly used for producing high-strength, complex metal components. Stereolithography (SLA) and Selective Laser Sintering (SLS) are primarily polymer-based processes and are not typically used for metals—SLA is for photopolymers, and SLS is mainly used with thermoplastics like Nylon. Multi Jet Fusion (MJF) is also a polymer-only technology. For clarity, this table distinguishes between metal and polymer additive processes and lists compatible materials accordingly.
| Technology | Process Description | Primary Materials | Material Type | Typical Applications | Layer Thickness Range | Surface Finish (Ra) | Build Speed |
|---|---|---|---|---|---|---|---|
| SLA (Stereolithography) | Uses UV laser to cure liquid photopolymer resin layer by layer | ABS-like resins, Standard resins, Tough resins | Photopolymer | Prototypes, Concept models, Medical models | 25–100 μm | 0.8–1.6 μm | Moderate |
| SLS (Selective Laser Sintering) | High-power laser sinters powdered material, typically nylon-based | Nylon (PA11, PA12), Glass-filled Nylon | Thermoplastic | Functional prototypes, End-use parts, Jigs & fixtures | 80–150 μm | 6–10 μm | Fast |
| MJF (Multi Jet Fusion) | Inkjet array deposits agents onto powder bed, fused by heating element | Nylon (PA12), Glass-filled PA12 | Thermoplastic | High-volume functional parts, Enclosures, Ducts | 80–100 μm | 4–8 μm | Very fast |
| DMLS (Direct Metal Laser Sintering) | Laser sinters metal powder particles to form dense metal parts | Aluminum (AlSi10Mg, AlSi7Mg), Stainless Steel (316L, 17-4 PH), Titanium, Inconel | Metal | Aerospace, Medical implants, Tooling, Complex brackets | 20–50 μm | 8–15 μm | Slow to moderate |
Notes:
SLA does not support metal printing and is included here for comparative context.
SLS and MJF are polymer-based and compatible with Nylon and ABS-like materials but not metals.
DMLS is the only process listed that enables true metal additive manufacturing with Aluminum and Steel alloys.
ABS as a material is not directly printable via SLS or MJF; however, ABS-like mechanical properties are achieved using specific engineering-grade thermoplastics in MJF and SLS.
From CAD to Part: The Process
Honyo Prototype Metal Additive Printing Process Overview
Honyo Prototype executes metal additive manufacturing through a rigorously controlled workflow designed for precision, efficiency, and compliance with aerospace, medical, and industrial standards. Our process integrates advanced digital tools with expert engineering oversight to transform client CAD data into certified end-use parts. Below is a detailed breakdown of each phase.
CAD Upload and Initial Processing
Clients submit 3D CAD models via our secure online portal, supporting industry-standard formats including STEP, IGES, and native CAD files. Our system performs automated geometry validation to confirm watertightness, manifold integrity, and minimum feature suitability for metal AM. Non-conforming files trigger immediate client notification with specific failure diagnostics. All data undergoes encryption per ISO 27001 protocols, with strict access controls ensuring IP protection throughout the workflow.
AI-Powered Quoting and Material/Process Selection
Upon CAD validation, our proprietary AI engine analyzes part geometry, material requirements, and functional intent to generate a technical-economic quote within 2 hours. The algorithm evaluates over 200 parameters including build orientation optimization, support structure density, residual stress prediction, and material waste minimization. Clients receive a dynamic quote detailing cost drivers, recommended materials (e.g., Ti-6Al-4V, Inconel 718, AlSi10Mg), and machine selection rationale based on part criticality and dimensional tolerances. This phase reduces quoting errors by 92% compared to manual methods, as validated in our internal 2023 audit.
Engineering-Led DFM Analysis
All quotes undergo mandatory Design for Metal Additive Manufacturing review by Honyo’s AS9100-certified engineering team. This phase focuses on mitigating AM-specific failure modes through:
Thermal distortion compensation via simulated build path analysis
Critical surface identification for post-processing requirements
Support structure optimization balancing part integrity and reclaim efficiency
Anisotropic property mapping for load-path critical features
Clients receive a formal DFM report with actionable recommendations, including risk-ranked modifications for improved yield. This step typically reduces print failures by 65% and eliminates costly rework loops.
Production Execution and In-Process Control
Approved jobs enter production on our fleet of calibrated industrial systems (EOS M400-4, Renishaw RenAM 500Q, SLM 500), all maintained to OEM specifications with quarterly NIST-traceable calibration. Key production protocols include:
Real-time melt pool monitoring with AI-driven anomaly detection
Inert argon atmosphere maintained below 100ppm oxygen
Layer-wise thermal imaging for distortion correction
Automated powder recycling with Hall Flowmeter validation
Each build includes full traceability from raw material lot (certified to AMS 7000 series) through to chamber environmental logs, stored in our blockchain-secured quality database.
Post-Processing, Validation, and Delivery
As-built parts undergo stringent post-production protocols:
Support removal via multi-axis CNC or wire EDM based on geometry complexity
Stress relief heat treatment per AMS 2750 pyrometry standards
Precision machining for critical interfaces (IT7 tolerances achievable)
Non-destructive testing (CT scanning, MPI) per client-specified NADCAP requirements
Final delivery includes full material certification, build parameter logs, dimensional CMM reports (ASME Y14.5), and surface roughness validation. Standard lead time is 10–15 business days from CAD approval, with expedited options available.
Process Performance Metrics
| Phase | Standard Lead Time | First-Pass Yield | Key Compliance Standard |
|——-|——————-|—————–|————————|
| DFM Analysis | 24–48 hours | 98.7% | ISO 13485:2016 Sec. 7.3 |
| Production | 5–7 days | 94.2% | ASTM F3301/F3316 |
| Post-Processing | 3–5 days | 99.1% | AMS-STD-2175 Class A |
This integrated workflow ensures Honyo delivers production-ready metal AM components with demonstrated 40% cost reduction versus traditional methods for complex geometries, while maintaining full regulatory traceability from digital model to certified physical part. Our closed-loop system continuously refines process parameters using build outcome data, driving sustained yield improvement across client portfolios.
