All precision prototypes are machined using optimized toolpaths and in-process probing to ensure dimensional accuracy and consistency, particularly for features such as undercuts, deep pockets, and thin walls. Multi-axis capabilities allow for reduced setups and improved geometric precision, critical for complex components in aerospace, medical, and robotics industries.
From CAD to Part: The Process

Honyo Prototype delivers precision prototypes through an integrated digital workflow designed to minimize iteration cycles and ensure manufacturability from the earliest stages. Our process begins when a client uploads their CAD model to our secure portal, initiating a fully automated yet engineering-validated sequence.
Upload CAD
Clients submit native or neutral CAD formats (STEP, IGES, Parasolid) directly to our cloud-based platform. The system performs initial geometry validation, checking for corrupt files, unit inconsistencies, and minimum feature size thresholds relative to target manufacturing processes. This step ensures only technically viable designs enter the quoting phase, reducing downstream errors.
AI Quote with Embedded DFM Analysis
Our proprietary AI engine generates a formal quotation within 2 business hours, but this extends beyond simple cost calculation. The system concurrently executes a preliminary Design for Manufacturability (DFM) assessment, evaluating over 200 geometric and material-specific parameters. The output includes a detailed cost breakdown and a manufacturability score (0-100) with specific risk flags. For example:
| DFM Focus Area | Critical Parameters Evaluated | Risk Threshold |
|---|---|---|
| Geometric Complexity | Undercuts, thin walls, aspect ratios | Score < 75 |
| Tolerance Stackup | GD&T feasibility, cumulative tolerances | Score < 80 |
| Material Constraints | Minimum bend radii, thermal distortion potential | Score < 70 |
This dual-output report allows clients to immediately understand cost drivers and make informed design adjustments before committing to production.
Engineer-Validated DFM
For designs scoring below 85 or requiring precision tolerances (±0.005mm or tighter), our manufacturing engineers conduct a manual DFM review. We collaborate directly with the client’s design team via secure video workshops to resolve high-risk issues—such as optimizing wall thickness for metal additive processes or suggesting alternative fixturing for 5-axis milling. This phase typically reduces physical prototyping iterations by 60-75% compared to traditional workflows.
Precision Production
Approved designs move to our climate-controlled manufacturing floor where we deploy process-specific equipment based on material and tolerance requirements:
Metal Prototypes: DMG MORI 5-axis mills (±0.002mm accuracy) or Renishaw metal AM systems
Polymer/Composite: Stratasys FDM with soluble supports or CNC-machined PEEK/ULTEM
Hybrid Assemblies: In-house finishing including anodizing, bead blasting, and CMM validation
Each prototype undergoes real-time process monitoring with IoT-enabled machines tracking tool wear, thermal drift, and vibration to maintain sub-10-micron repeatability. All critical dimensions are verified against the original CAD using Zeiss coordinate measuring machines.
Delivery with Full Traceability
Within the committed timeline (typically 5-12 business days for complex precision prototypes), clients receive:
The physical prototype with serialized traceability tag
Digital inspection report showing CMM data overlaid on CAD
Process logs including machine parameters and environmental conditions
Revised DFM documentation reflecting any in-production adjustments
This closed-loop system ensures that every precision prototype meets aerospace, medical, or semiconductor industry standards while providing the engineering data necessary for seamless transition to low-volume production. By embedding DFM into the quoting phase and leveraging automated validation, Honyo reduces time-to-prototype by 30% versus conventional prototype suppliers while maintaining first-article acceptance rates above 92%.
