3D Printing of Lattice & Bionic Structure Parts

Detailed Description

Our 3D printed lattice & bionic structure parts are innovative lightweight components produced by SLA or SLS additive manufacturing technology. Featuring controllable pore geometry, outstanding buffer performance and reduced weight, these custom structural series cover medical protective shells, wearable device frameworks, mechanical buffer parts and lightweight industrial prototypes. All products are completed with precise post‑curing and sandblasting treatment, obtaining clean burr‑free surfaces available for coating and assembly testing. Perfect for structural feasibility verification, wearable product development and small‑batch functional component manufacturing.

Available Surface Finishes

• As‑printed: Raw printing surface with visible powder/layer traces, for internal structural performance test only.
• Sandblasting: Uniform matte surface, remove residual powder, improve coating adhesion.
• Fine Polishing: Smooth outer surface, keep internal lattice structure intact, for demonstration display.
• Transparent Coating: Clear protective layer for resin lattice parts, maintain light transmission and anti‑aging property.

Structural & Functional Breakdown

• Custom‑Density Lattice Framework: Adjustable pore size and strut thickness to balance weight reduction and mechanical load‑bearing capacity.
• Integral Porous Bionic Forming: One‑piece forming of complex honeycomb/bionic network without assembly seams, guarantee structural continuity.
• Ventilation & Buffer Cavity Structure: Interconnected internal cavities realize air circulation and impact absorption, hard to achieve via CNC machining.
• Reinforced Boundary Structure: Thickened edge framework avoids local stress fracture during compression and impact.

Key Machining Highlights

• Complex Lattice Generative Printing: Support generative‑design bionic geometry, produce intricate porous structures unachievable by traditional subtractive processing.
• Controllable Material Performance: Select resin or nylon material to meet requirements of transparency, toughness or impact resistance.
• Strict Powder Removal Process: Complete internal cavity cleaning to eliminate residual printing powder inside tiny lattice gaps.
• Parameter‑Driven Customization: Adjust lattice parameters according to customer load‑testing requirements, realize targeted lightweight solution.
