Pure copper is a rare offering among online metal-printing services, because the metal is highly reflective and hard to process with conventional near-infrared lasers. Addireen, a Shenzhen company, built its metal AM hardware around that problem. It now sells copper parts through an online ordering system. According to VoxelMatters' report on AddireenNow, published October 28, 2026, the service covers the whole job: online quoting, design-for-additive-manufacturing (DfAM) review, printing, post-processing and part inspection. It handles pure copper, the copper alloy CuCrZr, AlSi10Mg aluminum, 316L stainless steel and Ti6Al4V titanium.
This piece looks at what the service actually sells: which materials you can order, how an order moves through the system, and where it might fit for makers and small engineering shops whose projects have outgrown plastic.
A Green-Laser Company Selling Copper Parts
Addireen's background matters here. VoxelMatters reports that in 2023 the company launched China's first green-laser metal 3D printing solution, aimed at highly reflective metals: pure copper, copper alloys and aluminum alloys. AddireenNow is the online services division built on that expertise. You don't buy the machine. You buy its output, and Addireen's engineers handle the process.
The service didn't appear overnight. A company announcement dated May 14, 2026 introduced the Addireen 3D Printing Platform, a portal where customers upload CAD files and get prices and lead times for industrial-grade titanium, aluminum and pure copper parts. In that release, Addireen says customers get access to what it calls China's largest copper 3D printing center and a fleet of more than 100 industrial additive manufacturing systems. It also gives one hard number for its main material: pure copper processed with green lasers reaches 99.8% relative density.
That figure is the one copper buyers will care about. A porous copper part loses much of the reason to choose copper in the first place. The 99.8% is Addireen's own claim, not an independent test. Treat it as the starting point for a conversation about your part, and ask for inspection data on your own geometry.
The Materials List, Read Closely
The two sources don't list exactly the same materials, and the differences are worth noting before you upload a file.
- Pure copper is on both lists and is the main attraction.
- CuCrZr, a copper-chromium-zirconium alloy, is also on both lists.
- AlSi10Mg and Ti6Al4V appear in both, covering the standard aluminum and titanium alloys used in metal powder-bed work.
- 316L stainless steel appears in VoxelMatters' list for AddireenNow.
- 6061 aluminum appears in the May instant-quote list.
Addireen's site also lists CuCrNb and CuSn10 among its copper materials. The May release doesn't include either in its instant-quote list, and VoxelMatters doesn't name them for AddireenNow. They may need a direct conversation rather than an automatic quote.
How an Order Moves Through the System
VoxelMatters describes the workflow in steps that will look familiar to anyone who has used an online CNC or sheet-metal service. Addireen's version adds a human review before production starts.
1. Upload and specify. You upload a CAD model and choose the material, quantity, post-processing and inspection requirements. Inspection is selected at the start, not added later. VoxelMatters lists the options as dimensional measurement, surface roughness testing, density testing, metallographic analysis and leak testing, with other tests arranged on request. That's useful for anyone who has received a metal part and then had to check it against the drawing alone.
2. Automated analysis. The platform analyzes the model and requirements and returns an initial quote and lead time estimate. The word "initial" matters: this is an estimate before an engineer has looked at the file.
3. DfAM review. If you go ahead with the order, Addireen's engineers review the design, material, quantity, tolerances, surface requirements, post-processing and inspection. VoxelMatters says the team provides DfAM recommendations if needed and confirms the production plan with the customer, so expect possible suggested changes, not just approval or rejection.
4. Coordinated production. Addireen then coordinates the chain from printing to inspection.
Yujing Xu, Addireen's Director of Global Business (the May release calls him Global Sales Director), explained the reasoning to VoxelMatters. Customers, he said, need more than a printed part. They need a component that meets defined dimensional, surface and performance requirements, with one team responsible from model submission through finished-part delivery. In the May announcement, Xu described the same goal as navigating the "last mile" of production.
That pitch addresses a real weakness in the bureau model. A metal part that comes off the build plate isn't finished. Support removal, heat treatment, machining of critical faces and dimensional checks can end up with different vendors, and each handoff adds delay and room for blame. One company owning the full chain doesn't guarantee a good part, but it does make clear who is accountable when a part is bad.
Why the Focus on Thermal Management
VoxelMatters reports that the service puts particular emphasis on thermal-management parts. That's the obvious market for a company whose specialty is copper: it names liquid cold plates, heat exchangers and optical transceiver heat sinks, which can use internal channels, thin walls and fine fins that machining can't easily produce. VoxelMatters says AddireenNow also supports automotive components, hydraulic manifolds, golf club heads and lightweight robotic structures. Those plausibly fit the aluminum, titanium and stainless options better than copper, though the sources don't pair each application with a material.
Hydraulic manifolds are a good example of why the DfAM step matters. A printed manifold works only if its internal passages can be cleaned of powder and its sealing faces end up within tolerance after post-processing. An engineer who checks those points before printing could save a costly reprint.
What It Means for Makers
For most hobbyists, a pure-copper printed part will stay rare and special. Neither source gives prices, so we can't say what a small copper cold plate costs. But the sources do support a few practical points.
First, if your project is limited by heat, such as a high-power LED, a laser diode mount, or a compact electronics enclosure that runs hot, there's now an online route to printed copper and CuCrZr that doesn't require knowing someone at an aerospace supplier. Second, the instant quote is just a first estimate. Only the post-order DfAM review confirms the production plan. Budget your schedule with that in mind. Third, specify inspection when you order. The workflow is built around it, and VoxelMatters lists density testing among the options, which is the obvious way to check the density claim on your actual part.
Finally, as with any overseas bureau, plan for shipping time and confirm that your file format, tolerances and surface callouts are clear before you submit. The engineering review can catch problems, but it works best with a clean drawing.
Bottom Line
AddireenNow is a sensible move for a company with specialized copper capability and, by its own count, more than 100 industrial machines. It wraps that capacity in an ordering process that ends with inspection, not just printing. The materials list matches what thermal and fluid-handling parts need. The real test, which neither source can settle, is whether quotes, lead times and inspected parts hold up once real orders start arriving.
