Researchers from the University of Massachusetts Lowell have developed a new method of hybrid manufacturing that conjoins FFF 3D printing and injection molding. Dubbed ‘injection printing’, the novel process increases production rates while significantly improving the strength and stiffness of parts. The study’s lead author, David Kazmer, has since filed a patent for the technology. […]
Argonne scientists use machine learning to predict defects in 3D printed parts
A team of researchers from Argonne National Laboratory and Texas A&M University have developed an innovative new approach to defect detection in 3D printed parts. Using real-time temperature data, together with machine learning algorithms, the scientists were able to make correlative links between thermal history and the formation of subsurface defects during the laser powder […]
Purdue University researchers 3D print bacteria grabbing colonoscopy capsules
Researchers from Purdue University have developed a 3D printed capsule that’s capable of sampling bacteria inside the human stomach. Designed to perform the role of a colonoscopy, the printed pill is able to capture bacteria (known as biome), not just in the colon, but the entire gastrointestinal tract. The “gut-oscopy” technique could be deployed alongside […]
Delft researchers formulate novel calcined clay-based cement for 3D printing
A team of researchers from the Delft University of Technology have formulated a new, calcined clay-based cement for extrusion 3D printing. When compared to traditional cement, the novel ceramic has an increased flow consistency, improved buildability, and enhanced hydration properties – all crucial for precision extrusion to take place. 3D concrete printing 3D printing with […]
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 […]
