Tsinghua Researchers 3D Print Complex Structures in 0.6 Seconds
Researchers at Tsinghua University in China, led by Dai Qionghai, achieved a breakthrough in ultra-fast 3D printing. Their computational optics technique produces complex structures with millimeter precision in just 0.6 seconds, with feature sizes as small as 12 micrometers and printing speeds up to 333 cubic millimeters per second.
This is a fundamental materials science breakthrough, not a consumer product — but it signals where the technology is headed. Current FDM and resin printers measure speed in mm/s of linear motion; this technique measures in cubic mm/s of volumetric creation. At 333 mm³/s, entire objects materialize nearly instantly using light-based curing. The 12-micrometer feature resolution means this could eventually serve medical implant and microfluidics manufacturing. For desktop 3D printing enthusiasts, this validates the industry's trajectory toward speed — Bambu Lab's 500mm/s was impressive; this is orders of magnitude beyond.

Japan Approves First Two-Story 3D Printed Earthquake-Resistant Home
Kizuki, a Japanese construction technology company, successfully passed strict earthquake-resistance tests with its two-story 3D printed reinforced concrete home. This is Japan's first government-approved two-story 3D printed house, demonstrating additive manufacturing viability in seismic zones and addressing labor shortages in construction.
Japan has among the world's strictest building codes due to seismic activity, so government approval of a 3D printed structure is a massive validation milestone. Construction 3D printing has been growing — ICON in the US, COBOD in Europe — but seismic certification is a different challenge entirely. The reinforced concrete approach (vs. ICON's Lavacrete) suggests Kizuki is using traditional materials in an additive process, which may ease regulatory acceptance. For the broader 3D printing community, this proves that additive construction can meet the highest safety standards.
Source notes
Two-story 3D printed reinforced concrete home. Passed Japanese government earthquake-resistance testing. Additive construction with traditional reinforced concrete. Addresses labor shortage in Japanese construction industry.
What it changes: First government-approved 3D printed multi-story building in Japan. Competes conceptually with ICON (US) and COBOD (Europe) in construction 3D printing.
- Construction time vs. traditional methods
- Cost per square meter compared to conventional housing
- Scalability for multi-unit residential development

Josef Prusa Invests in Czech Hockey Gear Startup MIRNIX
Josef Prusa, founder of Prusa Research, made a CZK 5 million strategic investment in MIRNIX, a Czech startup using additive manufacturing to create off-ice hockey equipment for storage, transport, and drying. The investment will help MIRNIX scale production and explore international markets.
This is notable not for the dollar amount but for who's investing and why. Josef Prusa is one of the most influential figures in desktop 3D printing, and his investment in a sports equipment startup using AM for production (not prototyping) signals his view of where additive manufacturing is headed: from making prototypes to making final products at scale. MIRNIX using AM for hockey gear — functional equipment that needs durability — is a real-world validation of desktop-scale additive manufacturing as a production tool.
Source notes
MIRNIX: Czech startup. Additive manufacturing for off-ice hockey gear (storage, transport, drying equipment). CZK 5M investment from Josef Prusa. Focus on production-scale AM, not prototyping.
What it changes: Niche sports equipment market. Prusa's investment signals confidence in AM for production. International expansion planned.
- Specific AM technology used — FDM, SLS, or MJF
- Unit economics vs. injection molding for hockey gear
- Target markets beyond Czech Republic
Wait if:You're not in the hockey equipment market
