Joining forces: fast-as-lightning 3D microprinting with two lasers

Micrometer-sized Structures in Just the Blink of an Eye

18-Oct-2022 - Printing objects from plastic precisely, quickly, and inexpensively is the goal of many 3D printing processes. However, speed and high resolution remain a technological challenge. A research team from the Karlsruhe Institute of Technology (KIT), Heidelberg University, and the Queensland ...

Scientists develop a new kind of printable, wearable insect repellent

12-Oct-2022 - A new type of insect-repellent delivery device has been developed by scientists from the Martin Luther University Halle-Wittenberg (MLU). With the help of a 3D printer, the active ingredient is first "encapsulated" and formed into the desired shape, such as a ring, which can then be worn and ...

Microscopic Octopuses from a 3D Printer

Newly developed smart polymers have “life-like” properties

06-Oct-2022 - Although just cute little creatures at first glance, the microscopic geckos and octopuses fabricated by 3D laser printing in the molecular engineering labs at Heidelberg University could open up new opportunities in fields such as microrobotics or biomedicine. The printed microstructures are made ...

Algorithm learns to correct 3D printing errors for different parts, materials and systems

Spin-out company formed

22-Aug-2022 - Engineers have created intelligent 3D printers that can quickly detect and correct errors, even in previously unseen designs, or unfamiliar materials like ketchup and mayonnaise, by learning from the experiences of other machines. The engineers, from the University of Cambridge, developed a ...

3D Laser Nanoprinters Become Compact

Researchers Show How 3-dimensional Nanostructures Can Be Printed Using Compact Desktop Devices

01-Dec-2021 - Lasers in conventional laser printers for paper printouts are very small. 3D laser printers for 3-dimensional microstructures and nanostructures, by contrast, have required big and expensive laser systems so far. Researchers of Karlsruhe Institute of Technology (KIT) and the Heidelberg University ...
