Copper 3D printing service

Copper 3D printing, dominated by mature LPBF(Laser Powder Bed Fusion) technology, has evolved into the mainstream customized manufacturing solution for high-conductivity industrial components. Qualified copper 3D printing projects center on hidden internal flow paths, integrated structures and high-precision electrical/thermal functional parts, while plain solid copper blanks usually belong to non-AM application scenarios. XIAOJIAO provides standardized full-set copper 3D printing service strictly following industrial RFQ specification from drawing review, DfAM optimization, LPBF printing, post-processing to full-item inspection, covering cold plate, heat sink, high-current busbar, RF waveguide and semiconductor precision copper parts for global OEM, IDC, auto and semiconductor manufacturers.

1 Core Definition: What Is LPBF-Based Copper 3D Printing

Copper 3D printing (LPBF) uses green/red laser selective melting of high-purity copper alloy powder layer by layer without mould, producing monolithic copper components with hidden internal manifold, microchannel and integrated functional features that CNC/casting cannot realize. AM is only cost-effective when part geometry brings exclusive value via complex internal design. XIAOJIAO adopts 515nm green laser LPBF core equipment for high-density pure copper forming, matching the industrial verification standard of mainstream copper AM manufacturers worldwide.

2 Which Parts Fit / Don’t Fit Copper 3D Printing

2.1 Ideal Candidates for Copper 3D Printing (Best Fit)

These 5 categories are core mature projects of copper 3D printing:

• Copper cold plate & microchannel liquid exchanger: built-in split manifold, irregular cooling flow, sealing surface & anti-leakage design;

• Compact high-density copper heat sink: dense pin-fin, gradient lattice, integrated airflow channel;

• High-current copper busbar & induction coil: local integrated cooling, compact wiring, multi-terminal integrated structure;

• RF waveguide & vacuum copper parts: ultra-smooth inner surface, complex cavity, tight dimensional tolerance for low insertion loss;

• Semiconductor precision copper hardware: ultra-clean structural parts with integrated cooling & vacuum sealing groove.

  All above items are XIAOJIAO’s mainstream customized products with abundant mass-production cases.

2.2 Not Suitable for Copper 3D Printing (Avoid AM Solution)

Standard solid copper products gain better cost via traditional processing: solid flat copper plate, regular bar/tube/sheet, decorative copper accessories, DIY model, unconfirmed functional prototype with undefined performance index. XIAOJIAO’s technical team will proactively remind clients to switch to CNC for these items during free RF drawing review to save procurement cost.

3 Three Core Copper Materials for Copper 3D Printing (Pure Cu / CuCrZr / GRCop-42)

XIAOJIAO’s full material lineup covers three mainstream industrial grades for copper 3D printing:

• High-purity OFC Pure Copper(C10200): ≥99.95%Cu,96~98%IACS conductivity, optimal for cold plate, heat sink, high-current busbar requiring superior thermal & electrical performance;

• CuCrZr Copper Alloy: 85~90%IACS, high tensile & high-temperature resistance, ideal for mold conformal cooling inserts, high-load aerospace copper components;

• GRCop-42: Cu-Cr-Nb alloy, outstanding high-temperature creep resistance, exclusive for aerospace combustion chamber & high-heat RF parts.All three powders adopt low-oxygen spherical raw material, full MTC material certification available per batch.
