Every 3D printed part we produce is engineered to meet your exact technical specifications and application requirements.
Core 3D Printing Technologies & Process Advantages
3D printing (Additive Manufacturing) revolutionizes plastic part production by enabling complex geometries, rapid turnaround, and design flexibility that traditional manufacturing methods cannot match. We master three mainstream 3D printing technologies, each tailored to specific plastic materials and application scenarios, with core technical highlights as follows:
1. Stereolithography (SLA) 3D Printing
- Technology Principle: Uses UV light to cure liquid photopolymer resins layer by layer (layer thickness 0.025-0.1mm), achieving ultra-fine details and smooth surface finishes.
- Key Specifications: Dimensional accuracy ±0.05mm (for parts ≤100mm) or ±0.05% (for parts >100mm); surface roughness Ra≤0.4μm; maximum build size 500×500×600mm.
- Material Compatibility: Standard resin, tough resin, flexible resin, high-temperature resin (heat resistance up to 200℃), and biocompatible resin (compliant with ISO 10993).
- Application Scenarios: High-precision prototypes, dental models, medical device components, and decorative parts requiring intricate details.
2. Fused Deposition Modeling (FDM) 3D Printing
- Technology Principle: Extrudes thermoplastic filaments (e.g., PLA, ABS, PETG) layer by layer at a molten state (melting temperature 180-260℃), making it ideal for functional parts and cost-effective prototyping.
- Key Specifications: Dimensional accuracy ±0.1mm (for parts ≤100mm) or ±0.1% (for parts >100mm); layer thickness 0.1-0.3mm; maximum build size 800×800×1000mm.
- Material Compatibility: ABS, PLA, PETG, Nylon, TPU (flexible), and carbon fiber-reinforced composites (for enhanced strength).
- Application Scenarios: Functional prototypes, tooling, jigs and fixtures, low-volume production parts, and structural components.
3. Selective Laser Sintering (SLS) 3D Printing
- Technology Principle: Uses a laser to sinter powdered thermoplastics (e.g., Nylon PA12) layer by layer, creating fully dense parts without the need for support structures.
- Key Specifications: Dimensional accuracy ±0.08mm (for parts ≤100mm) or ±0.08% (for parts >100mm); surface roughness Ra≤1.2μm; maximum build size 700×380×580mm.
- Material Compatibility: Nylon PA12, PA11, TPU, and glass fiber-filled PA (for high rigidity).
- Application Scenarios: Complex functional parts, gears, hinges, aerospace components, and parts with internal cavities or undercuts.
4. Specialized Post-Processing Technologies
Our service extends beyond 3D printing to deliver ready-to-use parts through targeted post-processing:
- Surface Finishing: Manual/automated sanding, chemical polishing, vapor smoothing (for ABS/PA), painting, and dyeing to enhance appearance and durability.
- Functional Enhancement: Anti-static, waterproof, or flame-retardant coating; bonding for large parts; and installation of threaded inserts or metal fasteners.
- Quality Optimization: Precision trimming of support structures, post-UV curing for SLA parts, and dimensional calibration to ensure consistency.

Standardized Customization Process (5-Step Rapid Delivery)
We’ve streamlined the 3D printing customization process to align with the speed of additive manufacturing, ensuring transparency and quality at every stage:
- Design Submission & Evaluation: Receive your 3D models (STL/STEP/IGES format) and clarify requirements—including performance needs (strength, flexibility, temperature resistance), batch size, and delivery timeline. We then recommend the most suitable 3D printing technology and materials.
- DFM & Design Optimization: Our engineering team provides free Design for Manufacturability (DFM) analysis tailored to 3D printing. We optimize wall thickness (minimum 1.5mm for FDM, 0.8mm for SLA), add necessary supports, and adjust geometries to avoid common defects like warping or layer separation.
- Material Selection & Prototype Printing: Based on your requirements, we select the optimal plastic material and print 1-3 samples. Small parts are ready in 1-3 working days, while large or complex parts take 3-5 days. We provide detailed dimensional inspection reports and functional test data for your approval.
- Post-Processing & Quality Confirmation: Once samples are approved, we perform required post-processing (sanding, painting, assembly) and conduct final quality checks—verifying dimensional accuracy, surface finish, and functional performance—before initiating mass production.
- Batch Production & Global Delivery: We scale to low-volume production (10-1000 pieces) with consistent quality control. Parts are packaged in shockproof materials to prevent damage during transit, and we offer flexible shipping terms (FOB, CIF, EXW) to ensure on-time delivery worldwide.
Common 3D Printing Issues & Professional Solutions
To ensure stable quality, we address typical challenges in 3D printed plastic part production with proven solutions:
| Common Issues | Causes | Solutions |
|---|---|---|
| Layer Separation/Warping | Insufficient bed adhesion, improper temperature settings, material moisture | For FDM: Heat the build plate (60-100℃), apply adhesion spray, dry filaments (40-60℃ for 4-6h), and adjust printing speed to improve layer adhesion. For SLA: Ensure uniform UV exposure and fully post-cure parts. |
| Poor Surface Finish (Roughness) | Thick layer thickness, unremoved support marks, material residue | Reduce layer thickness (0.05-0.1mm for SLA, 0.1-0.2mm for FDM); use precision trimming tools to remove supports; and perform sanding/polishing post-processing. |
| Dimensional Deviation | Inaccurate 3D model scaling, printer calibration issues, material shrinkage | Regularly calibrate printers (steps per mm, flow rate); scale 3D models to compensate for material shrinkage (e.g., +0.5% for ABS in FDM); and use high-precision SLA/SLS printers for tight tolerances. |
| Brittle Parts/Insufficient Strength | Wrong material selection, inadequate layer adhesion, low infill density | Choose tough materials (e.g., TPU for flexibility, carbon fiber-reinforced PA for strength); increase infill density (80-100% for structural parts); and optimize printing speed/temperature for better layer bonding. |
| Support Marks on Visible Surfaces | Improper support placement, low support density | Place supports on non-visible areas (e.g., bottom, internal cavities); use tree supports (SLA) or dissolvable supports (for complex parts); and reduce support density to minimize marks. |
