An affiliate of “National Additive Manufacturing Innovation Institute” America Makes, the latest edition of Additive Manufacturing journal is scheduled for publication in December 2018. Now in volume 24, this edition will feature over 50 research articles from institutions all around the globe including the University of Twente, Tokyo University of Science and the University of Milan.

At 3D Printing Industry, we examine some of the upcoming features of the journal: microscale 3D printed gold; supersonic electronics; and carbon fiber reinforcements for the Japan Aerospace Exploration Agency (JAXA).

University - Twente - UT - Netherlands - Researchers

At the University of Twente (UT), the Netherlands, researchers have developed droplet-based approach for 3D printing microscopic structures in gold.

Termed laser-induced forward transfer, or LIFT, this method creates structures with “unprecedented feature sizes of smaller than 10 μm”, unlocking a plethora of applications in the biomedical sphere.

Spiral - Experimentation

A free-standing 3D printed spiral produced in the experimentation can be seen below.

The full paper of this research, “Printing of Complex Free-standing Microstructures via Laser-induced Forward Transfer (LIFT) of Pure Metal Films,” can be accessed online here. It is co-authored by Matthias Feinaeugle, Ralph Pohl, Ton Bor, Tom Vaneker and Gert-willem Römer.

Printing - Research - UT - Bioprinting - Technique

Previous, 3D printing research at UT includes a rapid bioprinting technique termed “in-air microfluidics” as previously featured on 3D Printing Industry.

Adding to a growing body of integrated additive manufacturing approaches for electronics, a team at the Università degli Studi di Milano (University of Milan) have demonstrated a multimaterial approach for creating conductive devices.

Method - FFF - Material - Extrusion - Cluster

The method combines typical FFF material extrusion with supersonic cluster beam deposition (SCBD) – a technique commonly used for spraying thin films of material.

According to the abstract, “A multi-step fabrication procedure alternating FFF and SCBD was developed...
