Swedish researchers successful in 4D printing micron-scale soft robots

A team of researchers from Linköping University, Sweden, has developed a set of microactuators for soft micro robotics using a custom-built extrusion-based 3D printer. The actuators contain an electrically-active polymer that changes shape – after being printed – in the presence of an electrical charge, granting them 4D capabilities. While 4D printed soft robots are […]

Columbia researchers develop a new method for multi-material SLS 3D printing 

Researchers from Columbia University’s School of Engineering have demonstrated a novel Selective Laser Sintering (SLS) 3D printing process which allows multiple powders to be sintered in the same print run.  By inverting the laser inside an SLS 3D printer so that it points upwards, and replacing its powder bed box with glass plates, the researchers […]

Researchers 3D print endoscopic imaging device for improved cardio care

An international group of scientists led by the University of Adelaide and the University of Stuttgart has used 3D microprinting to develop an Optical Coherence Tomography (OCT) endoscope.  The research team’s novel probe fabrication technique uses side-facing freeform micro-optics (less than 130 µm in diameter) to 3D print directly onto single-mode fibers. Measuring just 0.48mm, the resulting […]

Brookhaven scientists use kebab-like structures to advance FFF 3D printing

Researchers from the Department of Energy’s Brookhaven National Laboratory (BNL) have devised a method of better understanding the Fused Filament Fabrication (FFF) 3D printing process.   Working with a team from Stony Brook University, the Brookhaven scientists developed a dual-scanning method, which enabled them to monitor material deposition during 3D printing in real-time. While testing their approach, […]

Oregon researchers develop lego-inspired 3D printed healing ‘bone bricks’ 

Researchers from Oregon Health & Science University (OHSU) have 3D printed miniature Lego-style ‘bone bricks,’ which are potentially capable of healing broken skeletal tissue.  The researchers’ tiny hollow blocks, which are only the size of a small flea, serve as scaffolding onto which both hard and soft tissue can regrow. Moreover, the stackable nature of the […]

Montreal researchers develop new droplet-based method of cell bioprinting

Researchers from the University of Montreal have developed a new method of cell bioprinting based on a drop-on-demand technique. Laser Induced Side Transfer, or LIST, utilizes a low energy nanosecond laser and the laws of microfluidic dynamics to jet living cells onto each other, additively stacking them to form larger droplets. The team of scientists […]

University of Dayton researchers create lower cost method of 3D printing nanoscale structures 

Researchers from the University of Dayton have published research describing an enhanced and more cost-effective method of 3D printing nanoscale structures.  The Opto-Thermo-Mechanical (OTM) nano-printing technique was found to be capable of printing on a nanoscale level of fewer than 100 nanometers (nm), or a thousand times smaller than a human hair. What’s more, because […]

French researchers successful in 3D printing super high-resolution optical glass

Researchers from the ICMCB-CNRS laboratory and the University of Bordeaux have developed a method of 3D printing phosphate glass via FDM technology. By first pulling the glass filament using a fiber drawing tower, the researchers were able to extrude complex geometries while maintaining the photoluminescence properties of the material. The team believes its direct approach to fabricating […]

Finnish researchers use 3D printing to improve nasal surgery planning

A team of researchers from Tampere University, Finland, has experimented with a new method of nasal surgery preparation using 3D printing. With the aim of determining whether or not 3D printing could realistically replicate the anatomy of a nasal cavity and the airflow through it, the team took to scanning and printing a set of […]

Report from European Patent Office shows 3D printing patent numbers increasing

A new study published by the European Patent Office (EPO) has revealed a number of interesting statistics and trends regarding innovation in additive manufacturing. The report points out the origins of all notable patent applications from 2000 – 2018 and the industries leading innovation with the most inventions. In general, there has been a global […]
