Technical Capabilities

The term “metal printing services” often leads to confusion, as some additive manufacturing processes are metal-capable while others are strictly for polymers. Below is a clarification of the specified technologies—SLA, SLS, MJF, and DMLS—including their technical capabilities and compatible materials such as Aluminum, Steel, ABS, and Nylon.

Note: SLA, SLS, and MJF are primarily polymer-based processes. DMLS is the only fully metal additive manufacturing method among them.

Technology	Full Name	Process Description	Material Compatibility	Layer Thickness Range	Build Speed	Surface Finish (Typical Ra)	Support Structures Required	Max Build Volume (Approx.)
SLA	Stereolithography	Uses UV laser to cure liquid photopolymer resin layer by layer	Photopolymer resins only (e.g., standard, tough, castable, high-temp); No metals or ABS/Nylon	25–100 μm	Moderate	0.8–1.6 μm	Yes	1450 x 750 x 500 mm
SLS	Selective Laser Sintering	High-power laser sinters powdered material (typically polymer)	Nylon (PA11, PA12), Glass-filled Nylon, TPU; No metals or ABS	80–150 μm	Fast	6–10 μm	No (self-supporting)	700 x 380 x 580 mm
MJF	Multi Jet Fusion	Inkjet array deposits fusing agent, then heated by lamps to fuse powder layer	Nylon (PA12), Glass-filled PA12; No metals or ABS	80–100 μm	Very Fast	4–8 μm	No	380 x 280 x 380 mm
DMLS	Direct Metal Laser Sintering	High-powered laser sinters metal powder layer by layer to form dense metal parts	Stainless Steel (17-4 PH, 316L), Tool Steel (Maraging), Aluminum (AlSi10Mg, AlSi7Mg), Titanium, Inconel	20–50 μm	Slow to Moderate	10–20 μm	Yes (metal supports)	250 x 250 x 325 mm

Key Clarifications:

DMLS is the only process listed that supports true metal printing, enabling the production of high-strength, functional metal components for aerospace, medical, and industrial applications.

SLA is a photopolymer process and cannot print metals, ABS, or nylon. It offers high resolution and smooth finishes but is limited to resin materials.

SLS and MJF are both powder-bed fusion technologies for polymers, with excellent compatibility with various nylon-based materials. They do not support ABS or metal printing.

ABS-like properties can be mimicked in SLS or MJF using specific nylons or TPU, but true ABS thermoplastic is not typically used in these processes.

For metal printing services involving Aluminum or Steel, DMLS is the appropriate technology. For Nylon or functional polymer parts, SLS or MJF are preferred. SLA is ideal for high-detail prototypes but not for end-use functional parts requiring thermal or mechanical durability.

From CAD to Part: The Process

Honyo Prototype’s metal printing service follows a rigorously defined workflow designed for precision, efficiency, and client transparency. This integrated process ensures manufacturability while minimizing lead time from initial concept to finished part.

CAD File Upload and Initial Processing
Clients initiate the process by uploading their 3D CAD model file through Honyo’s secure web portal. Supported formats include STEP, IGES, and native formats from major CAD platforms. Upon upload, our system performs an immediate automated validation check for file integrity, unit consistency, and basic geometric completeness. This step confirms the file is technically ready for downstream processing and identifies any fundamental issues requiring client clarification before quoting proceeds.

AI-Powered Instant Quoting
Leveraging proprietary machine learning algorithms trained on extensive historical production data, Honyo’s AI engine analyzes the validated CAD geometry in real-time. The system evaluates critical parameters including part volume, bounding box dimensions, feature complexity, required support structures, material selection from our certified alloy portfolio (e.g., Ti64, Inconel 718, AlSi10Mg, 316L), and surface finish requirements. Within seconds, the AI generates a comprehensive preliminary quote detailing estimated material cost, machine time, post-processing requirements, and a firm delivery timeline. This quote includes clear visual annotations highlighting areas potentially impacting cost or manufacturability, providing immediate actionable insight without manual engineering intervention at this stage.

Engineering-Led Design for Manufacturability (DFM) Review
Following client acceptance of the AI quote, the project enters our mandatory DFM phase. A dedicated Honyo manufacturing engineer conducts a thorough technical review using specialized AM simulation software. This is not an automated step; it involves expert assessment of thermal management considerations, build orientation optimization, support structure strategy, residual stress prediction, and critical feature validation against metal AM process capabilities. The engineer provides specific, actionable feedback to the client, often including revised CAD suggestions or process parameter recommendations. Key DFM focus areas are systematically documented as follows:

DFM Review Category	Specific Checks Performed	Typical Client Impact
Geometric Feasibility	Minimum feature size, overhang angles, cavity drainage	Avoids failed builds, reduces post-processing
Thermal Management	Heat accumulation zones, part symmetry, wall thickness variances	Prevents distortion, cracking, internal porosity
Support Strategy	Optimized placement, removability, interface surface area	Lowers cost, improves surface quality, saves time
Material & Finish	Alloy suitability, required HIP/HT, surface roughness spec	Ensures final part meets mechanical requirements

Client approval of the DFM report is required before production commencement, ensuring alignment on all technical parameters.

Precision Metal Additive Manufacturing and Post-Processing
Approved jobs are scheduled on our calibrated industrial metal AM systems (primarily EOS M Series and Concept Laser Mlab platforms). Build parameters are strictly controlled per material certification and DFM specifications. Real-time process monitoring with layer-wise thermal imaging and melt pool analysis ensures build integrity. Post-build, parts undergo a defined sequence including controlled cooling, support removal via wire EDM or machining, HIP (Hot Isostatic Pressing) if specified, heat treatment, precision CNC machining for critical datums or interfaces, surface finishing (as specified: bead blast, precision grind, polish), and comprehensive metrology. All steps adhere to our AS9100D-certified quality management system with full traceability of material lot, machine parameters, and operator logs.

Quality Verification and Global Delivery
Each shipment includes a complete first-article inspection report (FAIR) with CMM data against critical dimensions, material test certificates (MTC), and process validation records. Parts undergo final non-destructive testing (NDT) per client requirements, typically including MPI or X-ray for internal defects. Honyo manages global logistics through vetted partners, providing real-time shipment tracking. Standard delivery includes protective packaging meeting international transit standards, with options for expedited shipping and customs documentation support. Our process concludes with a formal delivery confirmation and an invitation for post-delivery technical feedback to continuously refine future projects. This structured approach ensures consistent delivery of flight-worthy or production-intent metal AM components with full supply chain integration.
