Jiangsu Runice 3D Technology raises €12M to scale core printer component production

Jiangsu Runice 3D Technology, a Chinese manufacturer of 3D printer components, has completed a funding round of nearly 100 million Yuan (approximately €12 million), announced on June 24, 2026. The round was led by Cowin Capital, with participation from Haojun Capital, Wuzhong Financial Holdings, and the Shihu Fund, and advisory from Flow Capital. Runice will use the funds to develop core technologies, build digitized manufacturing systems, strengthen international brand positioning, and expand a second production site in Dongguan. The company, founded in 2013, supplies hotends, extruders, and motion systems as OEM and ODM solutions to printer brands globally, operating under the Phaetus brand for high-quality components, FusRock for composite materials, and the Bulber Innovation Lab for new technologies.

This funding signals a maturing recognition that the value in the polymer FDM/FFF ecosystem is shifting upstream from complete printer brands to the component layer. As the market moves toward high-speed, multi-color, multi-material, and multi-head systems, the performance of nozzles, heatbreaks, extruders, and motion systems becomes the binding constraint on print reliability and material capability. Runice sits at a critical node in the supply chain: its components determine whether a printer can reliably feed filament, maintain speeds over long cycles, or process technical materials. The round reflects investor belief that the component aftermarket and upgrade market-spare parts, replacement hotends, and performance upgrades-is a standalone, growing segment, separate from the more volatile printer OEM market. This is a classic Chinese localization arc: Runice is not just matching Western component specs but integrating materials, service capacity, and customer references across its sub-brands to capture more value.

For the industry, the practical implication is that printer OEMs and service bureaus should evaluate Runice's component lines as a direct alternative to Western suppliers for high-throughput FDM/FFF systems. The company's ability to execute on its Dongguan expansion and digitized manufacturing will determine whether it can deliver consistent quality at scale, which is the real test for a component supplier. Buyers should treat this as a supply-chain diversification signal, not a technology breakthrough-Runice's success will hinge on repeatability and delivery, not novelty.
