Biomedical engineers at the University of Melbourne have developed an innovative 3D bioprinter that could transform drug discovery. This advanced system allows complex cellular structures to be printed in a matter of seconds , mimicking human tissue from brain to bone, and promises to significantly reduce animal testing.
3D bioprinter with acoustic waves improves cellular precision
The technology uses acoustic waves to precisely arrange cells in 3D printed tissues, solving one of the critical limitations of traditional methods, where incorrect cell arrangement compromises tissue functionality.
“Our approach allows for an unprecedented degree of control over cell positioning,” explained David Collins, leader of the research team. This improves cell viability and keeps the structure intact during the process.
The team has collaborated with leading centers such as Harvard and the Sloan Kettering Cancer Center , where the new bioprinter has been enthusiastically received. “Researchers recognize the potential of bioprinting, and our system greatly expands current capabilities,” said Callum Vidler, senior author on the project.
Furthermore, this bioprinter surpasses the traditional layer-by-layer method , which is slow and risks cellular integrity. The ability to print directly on lab plates speeds up the process and offers a powerful tool to advance oncology therapies and personalized treatments.
