01 | Who we are
A copper AM service built around finished parts
COPPER 3DP is the copper additive manufacturing service of Suzhou Como Precision Materials Co., Ltd. We review the drawing, manufacture the part, complete downstream operations, and supply the agreed inspection evidence.
The engineering discussion stays focused on the part: function, geometry, material state, downstream operations, acceptance evidence, quantity, and timing.
Send your drawingGreen-laser LPBF
Produce commercially pure copper and copper alloy parts on a platform matched to the geometry.
Finishing and machining
Define heat treatment, support removal, CNC features, sealing faces, threads, polishing, or plating.
Inspection and delivery
Agree dimensional, CT, pressure, leak, flow, conductivity, surface, and documentation requirements.
02 | What we make
Functional copper parts for heat, current, flow, and tooling
We manufacture prototypes and production parts when internal channels, compact heat-transfer area, shaped current paths, or part consolidation make conventional fabrication inefficient.
Thermal management
Cold plates, compact heat exchangers, heat sinks, cooling blocks, and integrated manifolds.
Semiconductor cooling
Cooling plates, heat spreaders, compact manifolds, and hardware for power electronics.
Electrical and induction
Induction coils, busbars, electrodes, shaped current paths, and high-current components.
RF and vacuum
Waveguides, RF cavities, conductive structures, and vacuum-facing copper hardware.
Flow and nozzle hardware
Nozzles, injectors, manifolds, flow distributors, and parts with integral cooling passages.
Tooling and high-heat hardware
Conformal-cooling inserts, thermal tooling, and copper-alloy structures for demanding environments.
03 | Thermal design support
From thermal requirements to manufacturable copper cooling hardware
A project can start with finished CAD or with heat load, temperature limits, coolant, flow or pressure-drop targets, available envelope, and interfaces. We turn those inputs into a scoped design, manufacturing, and validation route.
The selected geometry is project-specific. More surface area does not automatically mean better cooling once pressure drop, flow distribution, cleanability, and printability are considered.
Review the complete thermal design and validation workflow, or continue with the commercial paths for copper cold plates and copper heat exchangers.
- 01
Define the conditions
Map heat sources, duty cycle, temperature limits, coolant, flow or pressure limits, envelope, and interfaces.
- 02
Compare architectures
Assess channels, fins or microchannels, impingement, manifolds, and topology-led structures against the constraints.
- 03
Iterate the design
Balance thermal response, uniformity, pressure drop, strength, powder removal, machining, and inspection access.
- 04
Prepare validation
Define the agreed CAD and drawing scope, manufacturing route, prototype plan, and included simulation or test evidence.
Architecture, reconstruction, and evidence
Three gates before the cooling geometry is frozen
Metal AM expands the available surface, fin, and channel design space. The value is realized only when the thermal concept can be simulated under defined conditions, rebuilt as manufacturable geometry, and tied to an agreed validation plan.
Reference study | flow field
Screen the flow architecture
A topology-led path is a concept, not a guarantee. Compare flow coverage, local velocity, and pressure loss under the agreed coolant and boundary conditions.
Reference study | model reconstruction
Rebuild usable channel geometry
Convert optimization output into continuous passages with practical walls, powder exits, port transitions, machining stock, and inspection access.
Reference study | physical print
Plan manufacturing evidence
Use the physical build to review feature continuity, channel access, edge conditions, cleaning or powder removal, and the dimensional, flow, leak, or thermal checks needed before the design is frozen.
Two valid starting points
Bring CAD or bring the thermal boundary conditions
Existing CAD moves into DfAM and production review. A thermal brief starts with concept development before the prototype route is agreed. Performance targets remain tied to agreed inputs and project-specific validation.
Useful design inputs
- Heat load, source map, and duty cycle
- Temperature or thermal-resistance target
- Coolant, inlet conditions, flow, and pressure limits
- Envelope, ports, interfaces, and working pressure
- Material preference, quantity, and validation needs
04 | Production capability
Green-laser LPBF matched to your drawing
The drawing determines the material route, build class, orientation, supports, powder-removal strategy, and downstream operations. The quotation records the route selected for that part.
Laser route
532 nm green laser
Process route for reflective copper and copper alloy systems.
Build classes
5 envelope ranges
From compact development work to large-format production.
Largest build class
660 × 660 × 1300 mm
Final fit still depends on orientation, supports, and access.
Materials processed
Materials selected for the finished-part requirement
Conductivity, strength, temperature, heat treatment, final state, and acceptance method are reviewed together. Feedstock selection is one input to the finished-part manufacturing route.
Check your material and part
Commercially pure copper
Selected when thermal or electrical conductivity is the primary design driver.
CuCrZr / CuCr1Zr
Selected when conductivity must be balanced with strength and thermal stability.
CuCrNb
Assessed for application-specific copper alloy and elevated-temperature requirements.
Build capacity
Build capacity from compact to large-format parts
The final build class is confirmed after part size, material, geometry, quantity, and current production requirements are reviewed.
- Compact
- Ø100 × 100 mm
- Precision
- 160 × 160 × 200 mm
- Mid-format
- 350 × 350 × 500 mm
- Multi-laser

- Large-format
- 660 × 660 × 1300 mm
05 | How we work
One route from requirements to delivered part
The process is locked around the agreed inputs, drawing, and acceptance criteria, so design, printing, post-processing, inspection, and quotation describe the same deliverable.
- 01
Define the requirement
Send CAD or, for thermal-design work, the governing operating requirements, envelope, interfaces, quantity, and acceptance needs.
- 02
Lock the route
For scoped thermal-design projects, we develop and iterate cooling geometry before fixing the material, DfAM, finishing, and test route.
- 03
Print and finish
The part moves through green-laser LPBF, support removal, heat treatment, CNC, and specified finishing.
- 04
Inspect and deliver
Inspection evidence is produced against the agreed scope before packaging and international delivery.
Engineering review
Start with CAD or a clear thermal brief
Add quantity, target timing, heat load or operating conditions, and the requirements that cannot be compromised.
06 | Parts and applications
Copper geometry designed around the job
These part forms show where copper LPBF is most useful: compact thermal structures, integrated flow features, shaped current paths, and geometries that remove joints or assembly steps.
Heat-exchange structures
Dense surface area, compact flow paths, and monolithic thermal cores.
Induction and conductive paths
Integrated cooling, shaped current paths, and repeatable coil geometry.
Nozzles and flow hardware
Internal passages, consolidated bodies, and heat-flux-focused geometry.
Fins, lattices, and integrated features
Geometry that combines thermal, structural, and fluid functions in fewer pieces.
07 | Start a project
Send CAD or thermal requirements for engineering review
Submit what is already known. If CAD is not yet available, provide the heat load, temperature target, coolant, flow or pressure limits, available envelope, and interfaces. Quantity, material preference, inspection, and target timing help us return a clear scope.
What you get back
Route check
We confirm whether LPBF is the right route for the part, and say so when CNC, skiving, or brazed copper is the better choice.
DFM feedback
Wall, channel, fin, support, powder-removal, machining-stock, and inspection-access issues are marked before pricing.
Scoped quotation
Material route, heat treatment, machining, finishing, inspection, and delivery scope, or focused questions if inputs are missing.
