Technology & Products

Key Products

Micro-LPBF platform for high-precision metal 3D printing, achieving 5 micron layer thickness and 0.8 Ra surface roughness.

Technological Advantage

Achieves a breakthrough 5μm layer thickness (compared to the industry standard 30-50μm) and surface roughness of Ra ≥ 0.8μm. Their 'Deeply Open' parameter architecture allows researchers to customize laser power and scanning strategies, making it a preferred platform for advanced material labs.

Differentiation

Value Proposition

Enables the manufacturing of complex, miniaturized metal parts with sub-10μm precision and superior surface finish, significantly reducing the need for costly post-processing while allowing for support-free printing of complex geometries.

How They Differentiate

Achieves breakthrough 5μm layer thickness (compared to the industry standard of 30-50μm) and surface roughness of Ra ≥ 0.8μm. The Micro-LPBF technology allows for overhangs down to 10 degrees without supports and features a 500C pre-heated chamber and a 20-micron laser spot diameter. The company is a spinoff from the Fraunhofer Institute for Laser Technology (ILT), leveraging deep proprietary knowledge in laser-material interaction.

Recent coverage of Yunyao DeepVision

Why this company matters

Yunyao DeepVision occupies a narrow but technically demanding niche: micro-scale metal additive manufacturing via Micro-LPBF. Founded in 2021 by a team with direct lineage to Fraunhofer ILT, the original inventor of selective laser melting, the company aims to bridge conventional industrial LPBF and the sub-10-micron precision domain typically served by processes like two-photon polymerization or micro-EDM. Its core platform achieves a 5-micron layer thickness, roughly one-sixth the industry standard of 30–50 microns, and a surface roughness of Ra 0.8 microns, reducing or eliminating the need for post-processing on small, complex metal parts.

The technology uses a 20-micron laser spot diameter and a 500°C pre-heated chamber to print features such as stents, micro-implants, micro-nozzles, and cooling channels. A key differentiator is the ability to print overhangs down to 10 degrees without supports, enabled by proprietary algorithms for scan strategy and thermal management. The company also offers a 'Deeply Open' parameter architecture that lets researchers customize laser power and scanning strategies, positioning the platform as a tool for advanced materials development.

Target customers include precision engineering firms, medical device manufacturers, aerospace R&D centers, and micro-electronics component makers. Notable partners and early adopters include Fraunhofer ILT and RWTH Aachen University, reflecting the company's German research roots. Yunyao DeepVision has raised approximately $10 million from investors including Sequoia China Seed Fund, Shenzhen High-tech Investment Group, and Plug and Play China, and was recognized in 36Kr's '36 Under 36' list in 2023.

The competitive landscape includes 3D MicroPrint, Boston Micro Fabrication, and Cytosurge, all of which target similar micro-precision applications but often use different base technologies (e.g., electrochemical deposition or micro-stereolithography). Yunyao DeepVision's bet on Micro-LPBF gives it an advantage in metal-only applications and material variety, but the market for micro-scale metal parts remains small and fragmented. The company's ability to scale from research partnerships to production contracts with medical OEMs and aerospace primes will determine whether its Fraunhofer pedigree translates into commercial traction.
