Technical Capabilities
The term “CNC 3D files” is typically a misnomer when referring to additive manufacturing processes such as SLA, SLS, MJF, and DMLS. CNC (Computer Numerical Control) generally refers to subtractive machining, whereas SLA (Stereolithography), SLS (Selective Laser Sintering), MJF (Multi Jet Fusion), and DMLS (Direct Metal Laser Sintering) are additive manufacturing (3D printing) technologies. Below are the technical specifications for 3D printable file requirements and compatible materials for each of these additive processes, including common materials such as Aluminum, Steel, ABS-like, and Nylon.
| Process | Technology Type | Layer Resolution Range | Typical Accuracy | Minimum Feature Size | Supported Materials | File Format Requirements | Build Volume (Typical Max) |
|---|---|---|---|---|---|---|---|
| SLA (Stereolithography) | Photopolymer Resin (UV Laser) | 25 – 150 microns | ±0.1 mm (±0.004 in) | 0.5 mm | Standard, Tough, Durable, Clear, High-Temp Resins (ABS-like properties available) | STL, OBJ, 3MF (recommended: 0.01 mm chord tolerance, watertight geometry) | 145 x 145 x 185 mm (Desktop), up to 1500 x 750 x 500 mm (Industrial) |
| SLS (Selective Laser Sintering) | Powder Bed Fusion (Nylon-based) | 80 – 120 microns | ±0.3 mm (±0.012 in) | 0.8 mm | Nylon 12 (PA12), Nylon 11 (PA11), Glass-filled Nylon, Flame-Retardant Nylon (ABS-like mechanical behavior not direct, but functional analogs available) | STL, OBJ, 3MF (Watertight, manifold geometry required) | 300 x 300 x 300 mm (common), up to 700 x 380 x 580 mm |
| MJF (Multi Jet Fusion) | Powder Bed Fusion (Inkjet Array + Heating) | 80 – 100 microns | ±0.2 mm (±0.008 in) | 0.8 mm | Nylon 12 (PA12), Glass-filled Nylon, TPU (Flexible), PP-like materials (Nylon-based; no direct ABS but functional equivalents) | STL, OBJ, 3MF (High-quality mesh, no non-manifold edges) | 380 x 280 x 380 mm |
| DMLS (Direct Metal Laser Sintering) | Metal Powder Bed Fusion (Laser) | 20 – 50 microns | ±0.1 mm (±0.004 in), post-machining improves | 0.4 mm (dependent on geometry) | Aluminum (AlSi10Mg, AlSi7Mg), Stainless Steel (17-4 PH, 316L), Tool Steel (Maraging, H13), Titanium (Ti6Al4V), Inconel | STL, 3MF (Fine resolution recommended: 0.001–0.01 mm chord tolerance, support structures required) | 250 x 250 x 325 mm (typical), up to 500 x 400 x 400 mm (large-format systems) |
Notes:
File Quality: For all processes, watertight, manifold 3D geometry is critical. Non-manifold edges, gaps, or flipped normals can cause build failure.
Materials: ABS as a thermoplastic is not directly used in SLS, MJF, or DMLS, but Nylon-based materials (especially in SLS/MJF) offer similar toughness and thermal resistance. Aluminum and Steel are exclusively used in metal processes such as DMLS.
Supports: SLA requires support structures for overhangs; SLS and MJF use unsintered powder as natural support; DMLS requires metal support structures to manage warping and heat dissipation.
Post-Processing: All processes benefit from post-processing (e.g., sandblasting, heat treatment, machining) to improve surface finish and mechanical properties, especially for metal parts.
From CAD to Part: The Process
Honyo Prototype executes a streamlined, technology-driven workflow for CNC machining projects initiated through 3D CAD file submission. This process ensures rapid turnaround while maintaining rigorous quality standards essential for industrial clients.
The process begins with secure CAD file upload via our customer portal. We accept native and neutral formats including STEP AP203/AP214, IGES, Parasolid (.x_t, .x_b), and native SolidWorks, Creo, and Fusion 360 files. Upon submission, our system performs an immediate automated validation check for file integrity, unit consistency, and geometric completeness to prevent downstream delays.
Next, our proprietary AI quoting engine analyzes the validated CAD geometry. This system evaluates critical factors including part complexity, material stock requirements, feature tolerances, surface finish specifications, and machine time estimates. The AI cross-references real-time data on material costs, machine availability, and labor rates to generate a detailed, binding quote within 2 hours for standard parts. This eliminates manual quoting bottlenecks while ensuring cost transparency.
Following quote acceptance, the project enters our Digital Manufacturing Engineering (DFM) phase. A dedicated manufacturing engineer conducts a comprehensive manufacturability review using specialized CAM simulation software. This step identifies potential issues such as problematic tool access, thin wall deflection risks, or non-optimal fixture setups. We provide actionable DFM feedback within 24 hours, including specific recommendations for design modifications to enhance producibility, reduce costs, or accelerate lead times—always with clear engineering justification.
Approved designs proceed directly to production scheduling. Our facility utilizes a certified network of CNC machining centers including 3-axis vertical mills, 5-axis indexed and continuous machines, and precision turning centers. All parts undergo in-process inspections using calibrated CMMs and optical comparators against AS9102 first-article inspection standards where required. Material certifications and process documentation are maintained per ISO 9001:2015 protocols throughout manufacturing.
Final quality verification occurs prior to shipment, with critical dimensions rechecked against the original CAD model. Parts are packaged using ESD-safe and shock-absorbing materials appropriate for the component’s sensitivity. Standard lead times range from 3-7 business days for prototypes depending on complexity, with real-time production tracking accessible through the customer portal. Delivery includes full traceability documentation and optional FAI reports, ensuring seamless integration into client supply chains.
This integrated workflow reduces typical prototype lead times by 40% compared to traditional manufacturing service providers while minimizing design iteration cycles through proactive engineering collaboration.
