Rapid Prototyping utilizes 3D printing technologies to rapidly transform 3D CAD models into physical parts. It significantly shortens the R&D cycle from concept to market while drastically reducing upfront tooling costs.
Complete design validation within hours, supporting parallel testing and rapid modifications across iterations.
Eliminate expensive injection molding costs; highly cost-effective for small-batch trial production and custom parts.
Bypass traditional subtractive manufacturing limits to easily fabricate internal channels, hollow structures, and organic forms.
From CAD modeling to physical testing, 3D printing prototyping offers unmatched flexibility and accuracy for modern product design.
Evaluate scale, tactile feel, visual form, and ergonomics to align team and customer feedback swiftly.
Verify component tolerances, clearance fits, snap-fit elasticity, and multi-part assembly clearances.
Perform impact, fluid flow, and operational stress tests using tough, temperature-resistant, and durable materials.
By combining FDM and resin (LCD/SLA) 3D printing, high-precision visual enclosures and high-strength internal components can be produced concurrently within hours, speeding up R&D by over 60%.
| Stage | Core Objective | Tech | Recommended Material |
|---|---|---|---|
| Proof of Concept (PoC) | Validate scale, proportions, and basic aesthetics | FDM / LCD | ePLA-Lite / ePLA-Matte / Standard Resin |
| Visual / Display Prototype | High surface finish, painting, trade-show quality | SLA / High-Precision LCD | Bio-based High-Precision Resin / PLA+ |
| Functional Assembly Prototype | Fit checks, snap-fit strength, living hinges | FDM | PETG / ABS+ / PLA+ |
| Engineering Prototype | High temp resistance, impact resistance, stress testing | FDM / SLS | ePA-CF / ePC / PPS-CF / SLS PA12 |
Selecting the right eSUN filaments and resins based on testing requirements and budget delivers superior prototyping results.
Excellent printability and low shrinkage, ideal for large visual components and early-stage prototypes.
High toughness, strong impact resistance, and heat tolerance for enclosure assembly testing.
Exceptional strength and wear resistance, replacing lightweight metal parts for functional testing.
Ultra-fine surface finish with high detail accuracy, perfect for miniature components and precision prototypes.
If post-processing like sanding, painting, or thread tapping is required, choose ABS+ or PETG.For pristine, layer-line-free surfaces, opt for eSUN Photopolymer Resin Series
| Industry | Typical Application | Material Value Add |
|---|---|---|
| Consumer Electronics | Earphone shells, smartwatch cases, port snap-fits | High-precision fitting, drastically shortening aesthetic and structural validation cycles. |
| Automotive | Dashboard prototypes, air duct connectors, fluid test parts | Heat and pressure-resistant materials (ePA-CF) allow functional testing under real driving conditions. |
| Medical Devices | Equipment housings, handpiece grips, surgical guides | Biocompatible and customized prototyping, lowering tooling risks for medical equipment. |
| Industrial Gear | Robotic arm grippers, custom jig/fixture prototypes | Lightweight, high-strength materials to validate motion paths and clamping forces. |
For snap-fit tests, adjust Horizontal Expansion in your slicer between ±0.05mm to 0.1mm. For high-precision fitting parts, enable 'Outer Wall First' in print order settings.
| Step | Recommended Setting / Tip | Notes |
|---|---|---|
| Infill Density | 10%-15% (Visual) / 30%-50% (Functional) | Use Gyroid or Grid infill patterns to balance structural strength and weight. |
| Support Structure | Tree Supports | Reduces surface contact points, making removal easy with minimal scarring. |
| Post-Processing | Sanding (400-2000 grit) + Primer/Paint | ABS prototypes can be acetone vapor polished; resins require thorough cleaning and UV post-curing. |
