A team of researchers at Israel's Technion Institute of Technology have used 3D printing to recreate life-like complex blood vessel structures capable of supplying blood to tissue implants. The team aims to engineer thick tissue flaps tailored to patients' individual needs.
3D printing allows almost any form to take shape using layers of materials to produce a physical object from a 3D model file. However, when using conventional laser beams in the process, such as those that utilize Gaussian beam shapes, problems tend to arise.
In the last few decades, metal 3D printing has spearheaded the efforts in creating custom parts of intricate shapes and high functionality. But as additive manufacturers have included more alloys for their 3D printing needs, so have the challenges in creating uniform, defect-free parts.
A new, 3D-printable polymer nanocomposite ink has incredible properties -- and many applications in aerospace, medicine and electronics.
While laser-based 3D printing techniques have revolutionized the production of metal parts by greatly expanding design complexity, the laser beams traditionally used in metal printing have drawbacks that can lead to defects and poor mechanical performance.
Scientists from Trinity College Dublin and AMBER, the SFI Research Centre for Advanced Materials and BioEngineering Research, have discovered a way to fabricate tiny colour-changing gas sensors using new materials and a high-resolution form of 3D printing.
Linde, the world’s foremost industrial gases company, and EOS, a leading supplier of responsible manufacturing solutions via industrial 3D printing technology, combined forces to conduct an important study into the influence of oxygen in the print process chamber and its effect on the critical properties of aluminium alloy AlSi10Mg.
The Agency for Science, Technology and Research's (A*STAR) Institute of Bioengineering and Bioimaging (IBB) and Institute of Molecular Cell Biology (IMCB) have developed a Fluid-supported Liquid Interface Polymerization (FLIP) 3D printer which can rapidly print hydrogel structures with complex geometry, while addressing the key nutrient supply issue in bioprinting.
Robotic surgery has grown in popularity in recent years and the advent of 3D printing technology has provided innovative ways to deliver robotic surgery education. The use of animals and human corpses in robotic surgery training comes with many financial and ethical challenges that can be solved using synthetic organs.
Ultra-efficient 3D printed catalysts could help solve the challenge of overheating in hypersonic aircraft and offer a revolutionary solution to thermal management across countless industries.
