Researchers at the Max Planck Institute for Medical Research and Heidelberg University have developed a "touchless 3D printing" concept that utilizes acoustic holograms.
The technology has potential applications in biomedicine due to its gentle and non-toxic nature towards cells, as well as the ability to maintain sterility during the assembly process.
The method involves using multiple acoustic holograms to create precise 3D shapes.
- Acoustic holograms are used to create pressure fields for printing solid particles, gel beads, and living cells.
- Researchers used GPU acceleration and Google's TensorFlow software to create precise and complex structures faster than traditional 3D printing methods.
- The technology has limitations, including being constrained by the power of sound waves.
- Yet, it represents a "promising step forward" in sound wave-based 3D fabrication.
- In a separate study, Universiti Teknikal Malaysia Melaka (UTeM) researchers have created a 3D printer for more resilient parts from recycled ABS.
- Concordia University scientists have introduced a novel direct sound printing (DSP) approach that employs ultrasound waves to produce intricate and precise objects.
The new study is published in the journal of Advanced Sciences.
