III. Capital Markets & Policy
Investment Highlights

US-based Formlabs secured $150M Series E funding ($2B valuation), focusing on industrial resin printing.

Shenzhen’s Creality raised hundreds of millions in Pre-IPO funding to expand overseas desktop printer markets.

Policy Support

China: MIIT’s Standardization Pilot for High-End Equipment Manufacturing lists additive manufacturing as a core field.

EU: Launched "AMGTA" (Additive Manufacturer Green Trade Association) to promote circular economy standards.

IV. Challenges & Solutions
Material Costs: Industrial metal powders remain expensive (e.g., nickel alloy: $200-500/kg). Domestic substitution accelerates (e.g., AVIC MTS’ breakthroughs in high-temperature alloys).

Lack of Standards: ISO/ASTM jointly advancing aerospace certification standards for 3D-printed parts (pilot in 2025).

Safety & Ethics: Multiple countries restrict 3D printing of firearm components (e.g., US 3D Printed Gun Safety Act).

V. 2025 Trend Forecast
Hybrid Manufacturing Rise: CNC + 3D printing combo systems become factory staples (e.g., DMG MORI’s laser deposition).

On-Demand Cloud Manufacturing: Alibaba Cloud/Amazon build distributed 3D printing networks for "72-hour global delivery".

Sustainability Push: Bio-resins/recycled metal usage to exceed 30%.

Neural Interface Manufacturing: 3D-printed flexible brain electrodes enter clinics (competing with Neuralink).
