Copper 3D printing service

As advanced industries including aerospace defense, new energy vehicle, AI thermal management and precision electronics keep upgrading structural design standards, copper 3D printing has become the core manufacturing method to produce customized lattice, TPMS and gradient energy-absorbing copper components. Inspired by Nikon SLM’s authoritative test of 24 types of lattice sandwich armor plates, global designers gradually abandon traditional machining limitations and rely on mature copper 3D printing technology to develop multi-functional copper parts with lightweight, load dispersion, high heat dissipation and impact resistance. Unlike CNC, casting and forging which cannot realize integrated complex lattice topology, professional copper 3D printing via SLM green laser forms monolithic copper lattice from CAD file directly. As a trusted manufacturer focusing on customized structural solutions, XIAOJIAO provides full-cycle copper 3D printing service covering DfAM lattice design, SLM forming, post-processing and performance testing for defense, automotive and cooling industry clients.

1. Core Classification of Lattice Structures for Copper 3D Printing

All lattice parts manufactured by copper 3D printing fall into two major categories: strut-based lattice and surface-based TPMS lattice, with dozens of subdivided unit structures verified in Nikon’s 24-kind armor test. XIAOJIAO’s technical team customizes copper lattice types according to clients’ working conditions for energy absorption or thermal dissipation.

1.1 Strut-Based Lattice（Defense & EV Crash Core Option）

 Consists of nodes and supporting struts, split into bionic structure and engineered structure for copper 3D printing:

• Bionic Lattice: Diamond, Octahedron, Voronoi, Kelvin cell (widely used for armor energy absorption tested by Nikon SLM);

• Engineering Lattice: BCC, FCC, truncated octahedron, hexagonal lattice (optimized for vehicle anti-collision copper parts).These structures can be designed into gradient thickness layout via copper 3D printing, realizing directional load dispersion when subjected to sudden impact.

• 
  

1.2 TPMS Surface Lattice（Thermal Management Mainstream）

TPMS is the most popular bionic surface structure in modern copper 3D printing, simulating biological trabecular bone features with ultra-high specific surface area under limited volume. Gyroid, Diamond and Primitive are three mainstream TPMS types applied in XIAO’s copper heat sinks. TPMS copper via copper 3D printing expands heat exchange area by 180%+ vs solid copper while cutting weight by 30%~50%, perfectly solving the bottleneck of compact high-power chip cooling.

2 Core Technical Advantages of Copper 3D Printing for Lattice Parts

Traditional processing can only produce solid or simple hole copper parts, while copper 3D printing breaks multiple technical barriers for gradient/lattice copper components:

1. Free Integrated Forming: One-shot printing of 24 different lattice panels just like Nikon’s 12-laser SLM equipment, no splicing and welding, eliminate assembly gap and stress concentration;

2. Gradient Customization: Realize gradual cell size/thickness changing in single copper part via copper 3D printing, guide impact force/heat flow along pre-set paths;

3. Dual-Function Realization: Same copper component combines heat dissipation + anti-impact via mixed TPMS+strut lattice design;

4. High Material Utilization: Copper powder usage above 95, cut raw cost vs subtractive machining.

3 Main Copper Raw Materials & Printing Processes for Copper 3D Printing Lattice

3.1 Available Copper Materials（XIAO Standard Stock）EN: XIAOJIAO applies two core copper grades for customized lattice copper 3D printing:
