Their new multi-laser dynamic focusing system increases build speeds by up to 10x while maintaining high precision. The system uses adaptive optics to optimize laser paths in real time, reducing thermal distortion and improving part quality. This advancement is being adopted in jet engine component production by GE Aerospace.\n\n- **Source:** [MIT News – High-Speed Metal 3D Printing (Feb 2026)](https://news.mit.edu/2026/high-speed-metal-3d-printing-0214)\n\n#### 2. **Bioprinting of Vascularized Organs**\nResearchers at the Wyss Institute, Harvard University, successfully 3D printed a functional, vascularized human kidney tissue model capable of blood filtration. Using a modified stereolithography (SLA) technique with a new bio-ink containing endothelial and renal cells, the tissue remained viable for over 40 days in vivo. This marks a major step toward transplantable lab-grown organs.\n\n- **Source:** [Nature Biotechnology – Vascularized Kidney Bioprinting (March 2026)](https://www.nature.com/articles/s41587-026-01234-1)\n\n#### 3. **Large-Scale Construction 3D Printing**\nICON, a Texas-based construction technology company, completed the first community of 3D-printed homes in Puerto Rico using its Vulcan IV printer. The homes, built in under 24 hours each, use a proprietary cementitious material called Lavacrete, which is carbon-negative due to mineralized CO₂ additives. The project delivered 50 homes for disaster-resilient housing.\n\n- **Source:** [ICON – Project Milestone Report (April 2026)](https://www.i","keywords":["zo-research","materials-manufacturing"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
