Professional 3D Printing Services Empower Complex Designs And Small-Batch Production

I. Core Service Advantages

- Easily achieve complex structures, breaking through the limitations of traditional processes: Supports integrated printing of complex designs such as hollow structures, lattice patterns, special-shaped surfaces, and internal flow channels, eliminating the need for component disassembly and assembly, improving structural integrity by over 80%. For example, topologically optimized aerospace brackets and mold inserts with internal cooling channels can be directly printed, achieving structural tolerances within ±0.1mm, difficult to achieve with traditional processes.

- Efficient and flexible small-batch production, significantly reducing cycle times: Small-batch production of 1-500 pieces can be achieved without mold creation, shortening production cycles by 60%-70% compared to traditional injection molding/casting (delivery from design to finished product as fast as 24 hours). Unit costs are flexibly adjusted based on batch size, saving 50%-80% of initial investment in small-batch production compared to mold creation. This solution is ideal for product R&D, trial production, and customized orders.

- Compatible with multiple materials and processes to meet diverse performance requirements: We offer mainstream processes such as FDM (fused deposition modeling), SLA (stereolithography), and SLM (selective laser melting), and are compatible with over 20 materials, including ABS, PLA, photosensitive resin, nylon, titanium alloy, and aluminum alloy. We recommend process-material combinations based on part applications (e.g., high-temperature resistance, high strength, and light transmittance). For example, SLM titanium alloy parts require a tensile strength of ≥900 MPa, while SLA photosensitive resin parts require a surface roughness of Ra ≤0.05 μm.

- Full-chain support from design to production to lower R&D barriers: We employ a professional design team and provide services such as 3D model repair, topology optimization, and process feasibility analysis. Based on customer-provided 2D drawings or preliminary 3D models, we optimize the structure to improve printing efficiency and part performance. Pre-print simulations help prevent defects such as warping and interlayer delamination, resulting in a first-time print pass rate exceeding 95%.

II. Core Application Areas

(I) Product R&D and Prototyping

- Industrial Design Prototypes: Rapidly print prototypes of consumer electronics (such as phone cases and earphones) and home appliances. The SLA process achieves highly realistic surface effects (such as matte and glossy finishes), enabling designers to complete multiple version verifications within 3-5 days, accelerating product iteration.

- Functional Test Prototypes: Print functional prototypes of automotive parts (such as sensor brackets) and mechanical structural components. Using nylon (impact resistance ≥ 50 kJ/m²) for assembly and performance testing, this allows for early detection of design flaws and reduces mold opening risks.

(II) Aerospace and Medical

- Aerospace Lightweight Components: SLM processes titanium alloy aerospace brackets and aluminum alloy engine parts. Lattice structure design reduces weight by 30%-40% while ensuring strength compliance, meeting the lightweight requirements of spacecraft.

- Custom Medical Devices: 3D printing of personalized orthopedic guides (made of resin, with an accuracy of ±0.05mm) and dental implant models, tailored to the patient's anatomy and enhancing surgical precision; printing of rehabilitation aids (such as customized hand braces) that balance comfort and functionality.

(III) Industrial Manufacturing and Molds

- Small-Batch Custom Parts: Printing small batches of non-standard accessories (such as grippers and connecting shafts) for the automation equipment and robotics industries. No mold creation is required, and delivery is completed within 7-10 days, addressing the long production cycles and high costs associated with traditional small-batch production processes.

- Rapid Molds and Tooling: 3D printing resin mold inserts and welding fixtures. The molds can produce 100-500 parts in injection molding, with a positioning accuracy of ±0.1mm. This reduces production cycles by 50% and costs by 40% compared to traditional metal molds/tooling.

(IV) Cultural and Creative Industries and Consumer Sector

- Customized Cultural and Creative Products: Print personalized figurines, art ornaments, and custom gifts. Supporting color printing and multi-material splicing, the product can reproduce intricate details (such as hair and relief textures), meeting the "small-batch, personalized" needs of cultural and creative products.

- Wearable Device Accessories: Print customized straps and cases for smart wearable devices. Made of flexible resin or nylon, they combine lightweight and comfort, allowing for quick design adjustments based on user needs.

III. Core Technology Support

- Multi-process, high-precision equipment cluster: Equipped with industrial-grade FDM printers (such as the Ultimaker S5, with a printing accuracy of ±0.05mm), SLA (Solid Light-Stage Lamination) printers (such as the Formlabs Form 3+, with a layer thickness of 0.025mm), and SLM (Structure Layer Metallization) printers (such as the EOS M290, with a positioning accuracy of ±0.02mm). These printers cover a wide range of materials and precision requirements, enabling the printing of large parts up to 1.2m × 1.2m × 1.2m.

- Design and Simulation Technology: We use Autodesk Fusion 360 and Magics for 3D model processing and slicing, and ANSYS for thermal stress simulation during the printing process to predict part deformation trends and adjust slicing parameters. We employ support structure optimization algorithms for complex structures to reduce support material usage and post-processing workload.

- Material R&D and Quality Control: We collaborate with renowned domestic and international material manufacturers to ensure stable material properties (e.g., nylon elongation at break ≥ 25%, titanium alloy hardness ≥ HRC30). Quality inspection utilizes blue light scanners (accuracy ±0.03mm), tensile testing machines, and hardness testers to fully inspect part dimensions and mechanical properties to ensure they meet customer requirements.

- Digital Production Management: We implement an MES system to enable real-time order progress tracking, equipment status monitoring, and printing parameter traceability. Customers can view order progress and inspection reports online. We also establish standardized post-processing processes (such as cleaning, curing, polishing, and coloring) to ensure consistent part appearance and performance.

IV. Frequently Asked Questions (FAQs)

- Q: What are the differences in the application scenarios of different 3D printing processes? How do I choose one? A: FDM is suitable for low-cost, high-durability plastic parts (such as jigs and fixtures); SLA is suitable for high-precision, smooth-surfaced resin parts (such as exterior prototypes); and SLM is suitable for high-strength metal parts (such as aerospace components). Our process team will recommend the optimal solution based on the part's material, precision, and strength requirements.

- Q: What is the achievable accuracy of 3D printed parts? What is the surface roughness?

A: Plastic part accuracy is ±0.05-±0.1mm, and metal part accuracy is ±0.02-±0.05mm. Surface roughness for SLA resin parts is Ra ≤ 0.05μm, for FDM plastic parts is Ra ≤ 3.2μm (can be reduced to Ra ≤ 1.6μm through post-processing), and for SLM metal parts is Ra ≤ 6.3μm (can be reduced to Ra ≤ 1.6μm after polishing).

- Q: What is the minimum order quantity for small batch production? What is the maximum print size limit? A: There's no strict minimum order quantity, and we support custom orders of just one piece. Maximum build sizes: 1.2m × 1.2m × 1.2m for FDM, 0.3m × 0.3m × 0.3m for SLA, and 0.25m × 0.25m × 0.3m for SLM. For oversized parts, we can use segmented printing with precision assembly.

- Q: What's the lead time from design files to finished product? Are you able to provide emergency service?

- A: Simple parts can be delivered within 24-48 hours, while complex parts or small batches (10-50 pieces) can be delivered within 3-7 days. We support urgent orders, with expedited delivery within 12 hours through priority scheduling (depending on the complexity of the part).

- Q: How does the lifespan of 3D-printed parts compare to those produced using traditional methods? A: Under the same material and working conditions, the service life of 3D printed parts is comparable to that of traditional processes. The service life of some topologically optimized parts (such as lattice structure parts) can be increased by 15%-20% due to more uniform stress distribution. The mechanical properties and service life of metal parts can be further improved through heat treatment (such as aging and quenching).
