|
Selective laser sintering, stereolithography, fused-filament fabrication, selective laser melting, and binder jetting.
|
Fused-filament fabrication, desktop or professional stereolithography, digital light processing, and resin-based printing.
|
| Typical Material Options |
Aluminum, stainless steel, tool steel, titanium, nickel alloys, PA12, high-temperature polymers, and reinforced engineering polymers.
|
Nylon, TPU, ABS-like resin, tough resin, castable resin, aluminum, stainless steel, and selected titanium alloys.
|
PLA, PETG, ABS, ASA, TPU, standard resin, tough resin, and other commonly available prototyping materials.
|
| Typical Build-Volume Range |
Approximately 250 × 250 × 250 mm to more than 1,000 × 1,000 × 1,000 mm, depending on the process and machine platform.
|
Approximately 150 × 150 × 150 mm to 700 × 380 × 580 mm across different technologies.
|
Approximately 120 × 120 × 120 mm to 350 × 350 × 400 mm for professional and compact production systems.
|
| Typical Dimensional Accuracy |
Often about ±0.05 to ±0.20 mm, subject to part size, geometry, material, build orientation, and post-processing.
|
Commonly about ±0.10 to ±0.30 mm for small and medium parts, depending on technology and production parameters.
|
Commonly about ±0.10 to ±0.40 mm; tighter tolerances usually require machining or other finishing operations.
|
| Typical Surface-Finish Capability |
As-printed surfaces may be approximately Ra 6–20 µm for selected polymer or metal processes; machining, polishing, blasting, or coating can improve the finish.
|
Generally suitable for functional prototypes and presentation models; sanding, vapor smoothing, tumbling, painting, and machining may be available.
|
Suitable for visual models and basic functional testing; manual sanding, priming, painting, and light machining are commonly offered.
|
| Production Quantity |
Repeated batches from tens to thousands of parts, depending on part size, qualification requirements, and machine capacity.
High-volume capable
|
One-off parts through low-volume batches, commonly from 1 to several hundred pieces.
Flexible batch sizes
|
One-off prototypes and small batches, commonly from 1 to approximately 100 pieces.
Prototype focused
|
| Typical Lead Time |
Approximately 2–8 weeks for qualified production orders, including engineering review, production, inspection, and finishing.
|
Approximately 3–15 business days for standard prototypes; complex metal parts or finishing may require additional time.
|
Approximately 1–7 business days for standard prototypes, subject to geometry, quantity, material availability, and shipping location.
|
| Quality Documentation |
May include material certificates, build records, dimensional inspection reports, process traceability, and first-article inspection documentation.
|
Usually includes dimensional inspection on request, material information, production records, and basic quality reports.
|
Usually includes order confirmation, material specification, and basic visual or dimensional checks; formal inspection is often an additional service.
|
| Common Certifications and Controls |
Buyers may request ISO 9001, ISO 13485, AS9100, controlled-process documentation, or customer-specific qualification evidence.
|
ISO 9001 or documented internal quality procedures may be available; certification scope should be verified for each facility.
|
Basic quality-management procedures are common; formal industry certifications may be limited or dependent on the supplier.
|
| Global Buyer Support |
Dedicated account management, engineering review, export documentation, regional logistics, and long-term supply agreements.
|
Online quoting, technical consultation, international shipping, design-for-additive-manufacturing feedback, and project-based support.
|
Online ordering, automated quotation, standard international delivery, and limited design-support services.
|
| Cost Structure |
Higher engineering, qualification, tooling, and inspection costs; lower unit cost may be achieved through repeat production and optimized nesting.
|
Moderate per-part pricing with separate charges for engineering, finishing, inspection, and expedited production.
|
Lower entry cost for simple prototypes, but unit pricing can rise quickly for large parts, premium resins, complex supports, or urgent delivery.
|
| Main Buyer Risk |
Longer qualification cycles, higher minimum project value, and stricter requirements for design approval and process validation.
|
Capability and quality may vary between facilities or technologies; the buyer should confirm machine type, material grade, and inspection scope.
|
Limited repeatability, smaller build volumes, fewer certification options, and reduced suitability for demanding end-use applications.
|
| Recommended Selection Criteria |
Choose when traceability, repeatability, engineering validation, certified materials, and production capacity are more important than the lowest initial price.
|
Choose when a project needs several technologies, specialist advice, low-volume production, or a balance between speed and engineering performance.
|
Choose when speed, accessible pricing, design iteration, and short-run prototyping are the primary business objectives.
