Nanjixiong introduction
Rongyue does not primarily sell finished printed products or industrial machines. It supplies the underlying control technology for full-color desktop and binder jetting equipment.
On October 14, 2026, Nanjixiong interviewed company representative Mr. Zheng at TCT Shenzhen. Shanghai Rongyue Electronics began developing piezoelectric inkjet control boards and software in 2002 and entered printing in 2017, nearly a decade ago. Exhibits included metal binder jetting systems and samples, plus complete desktop full-color solutions that have gained attention over the past two years.
Binder-jetted metal jewelry
Gold-plated pendants were made by binder jetting 316L stainless powder and then plating. Zheng said the approach does not offer cost or efficiency advantages for mass production but suits process validation, pre-production evaluation and custom batches of several dozen.
The desktop binder jetting machine has a 150 × 75 × 75 mm build volume and has been available for two to three years with a stable structure. Universities and institutes use it for material development and process studies. Despite its size, it targets industrial quality, with repeatedly refined printhead drive electronics, control software and algorithms.
Full-color printing directly from AI models
The popular full-color area featured transparent amber pendants containing small insect and animal forms, with improved color and transparency compared with two years earlier.
AI is a major driver. Text or images can now generate geometry and color with little adjustment, reducing modeling and repair barriers. Zheng said the exhibited pendants were printed directly from AI-generated models. Nanjixiong took three samples—a bee, crab and fish—and noted their clear appearance.
Rongyue supplies a complete package: boards, drivers, printhead integration, inks, slicing and RIP software. Its controls run in some domestic desktop color printers.
Current full-color 3D and 2.5D systems still use imported heads. Zheng believes that domestic multichannel heads costing a few hundred yuan, or existing suppliers offering comparable pricing, could bring complete systems into the FDM price range. He also emphasized that FDM retains advantages in size and speed, so the technologies can coexist.
Supporting a broad range of inkjet processes
Other exhibits included printed sand molds, polymer powder thermal-fusion solutions and ceramic parts made from nanoscale slurries. Zheng said Rongyue can provide head controls and complete software for inkjet applications whether they deposit binder, colored ink or nanoscale slurry.
Nanjixiong considers the company an important but less visible part of the supply chain. While equipment brands compete on recognition and distribution, Rongyue tackles boards, head drivers, ink control and RIP software behind the scenes.
Nanjixiong's observation
Consumer full-color printing reflects maturation of an entire chain: inkjet controls, heads, inks and AI modeling. If domestic heads mature sufficiently, desktop machines could reach the several-thousand-yuan range, moving beyond a niche position. The timeline depends substantially on printhead development.
