European and Chinese Startups Raise Capital for Seed Tech and Space 3D Printing

Gravity Gardens was founded in 2024 by Paulino Valdés, its Founder and CEO, and Robin Le Vigouroux, co-founder and CTO. EU-Startups reported that the technology was developed with support from the European Space Agency Business Incubation Centre (ESA BIC) Noordwijk.

Separately, Chinese metal 3D printing firm Xinjinghe Laser Technology Group has secured an equity funding round co-led by CMC Capital's Huawen Qingneng fund and the Chuzhou local government. According to Ventureburn, the company intends to use the capital to build a new aerospace additive manufacturing hub in Chuzhou and to expand its production capacity.

Founded in 2015 and headquartered in Huzhou, Zhejiang, Xinjinghe manufactures industrial metal 3D printing equipment and offers direct printing services, working across powder-bed, powder-fed and wire-fed additive routes with build sizes ranging from hundreds of millimeters to several meters. Ventureburn reported that the firm already supplies models to major Chinese aerospace groups, and has also secured server liquid-cooling component orders from a global compute-chip maker.

The Hamburg deeptech firm is developing muon-based imaging to inspect dense, safety-critical parts that conventional X-rays cannot fully penetrate.
