Scientists have developed 3D printed neurons capable of communicating with brain cells. This breakthrough could lead to advancements in understanding brain function and developing treatments for neurological disorders. The printed neurons were able to form connections with existing brain cells in lab experiments. This technology opens up new possibilities for studying the brain and potentially creating personalized treatments for conditions like epilepsy and Parkinson's disease. The research represents a significant step forward in the field of neuroscience and bioengineering.
Rice University researchers have developed a new method for 3D printing electronics using microwaves. This innovative technique allows for the rapid fabrication of complex electronic components with high precision. By utilizing microwaves to selectively heat materials, the researchers were able to create intricate circuit patterns on a variety of surfaces. This approach could revolutionize the production of electronic devices, making them more customizable and cost-effective.
Bambu Lab has surpassed Creality as the leading budget 3D printer brand globally, with a 37% share in the sub-$2,500 segment. The resurgence in the 3D printer market is attributed to the rise in budget options, with entry-level shipments increasing by 47% in Q4 and 26% throughout 2025. Chinese manufacturers dominated the entry-level market, with Bambu Lab's MakerWorld platform gaining significant traction. In contrast, the professional 3D printer segment experienced declines, but overall growth is expected across all price segments in 2026.
An inventor has created a filament dryer that not only dries filament for 3D printing but also mines Bitcoins, utilizing waste heat from the process. This new prototype is capable of 6 TH/s at 140W and is part of a lineup of hobbyist-focused mining devices. The filament dryer helps prevent common printing issues caused by moisture absorption and offers a proactive solution for maintaining filament quality. It is likely that this new device shares underlying technology with the inventor's previous 3D printer that also doubled as a Bitcoin miner, hinting at further scalability and innovation in this unique niche market.
