Researchers Investigate Tensile Properties of 3D Printed PLA Specimens: Is 80% Infill Best?

Comparison between 3D printed products from both recycled and virgin PLA. Plastic is still one of the most popular, least expensive 3D printing materials, and polylactic acid, better known as PLA, is at the top of the bunch, due to its high strength, biocompatibility, and biodegradable nature. A lot of studies have been completed regarding... Read More »

University of Michigan Researchers Develop New Ultrafast 3D Printing Technique: Two-Color Irradiation

[Image: Evan Dougherty/Michigan Engineering] University of Michigan researchers have developed a new vat polymerization 3D printing technique that produces objects at up to 100 times faster than current 3D printing techniques, as detailed in a paper entitled “Rapid, continuous additive manufacturing by volumetric polymerization inhibition patterning.” 3D printing has not yet fully lived up to...

Researchers Improve Femtosecond Selective Chemical Etching

In a paper entitled “Polarization-insensitive space-selective etching in fused silica induced by picosecond laser irradiation,” a group of researchers discusses space selective chemical etching, which can be achieved when fused silica is irradiated with focused femtosecond laser beams. Femtosecond lasers are a valuable tool for creating 3D microstructures in transparent materials, including glass. The technique... Read More »

3D Printing Cell Cultures Using PulMA Hydrogels

Biomimetic hydrogels offer several opportunities in medical applications, according to a group of researchers in a paper entitlted “Polysaccharide hydrogels for multiscale 3D printing of pullulal scaffolds.” But the generation of synthetic microenvironments that simulate the effects of natural tissue niches on cell growth and differentiation requires new methods to control hydrogel feature resolution, biofunctionalization and...

Researchers Develop 3D Printed Smart Hydrogel That Can Walk Underwater and Pick Up Objects

Pairing 3D printing with smart technology has led to some amazing innovations, such as metal parts that can track the performance of machines, windows that can keep your car cool in the sun, and ink that can change color and shape. Now, researchers from Rutgers University-New Brunswick have developed a 3D printed smart gel that is... Read More »

ORNL Collaboration Results in 3D Printed Stainless Steel Target for Producing Important Medical Isotope

3D printing is increasingly finding use in the manufacture all sorts of end-use products, but it can also lend a hand to researchers on the way to reaching a final goal. A good example of this is a recent project that Oak Ridge National Laboratory (ORNL) in Tennessee, run by the Department of Energy (DOE)... Read More »

2.5D Inkjet Printing Technique for Fabricating Precision Optical Components

There have been many breakthroughs with optical 3D printing, and now researchers in Switzerland are introducing a new one. The team, from the Swiss Center for Electronics and Microtechnology (CSEM), developed an inkjet printing technique for manufacturing precision optical components, like waveguides, which allow a signal to propagate without a lot of energy loss by...

Research Leads to Swedish Startup and New 3D Printable Graphene Material

The way we talk about graphene, which is often used in 3D printing applications, it’s almost like the one-atom-thick, two-dimensional carbon material is magical. Graphene is lightweight, and is both the thinnest and the strongest material known to man – 200 times stronger than steel, but 12% more lightweight than the second lightest material in...

Digital Sea Turtles Swim Across Researchers’ Screens with 3D Scanning Project at UMass Amherst

3D scanning technology has allowed scientists to begin building databases of 3D models of animal fossils and preserved specimens, leading to some impressive online collections. 3D models created with this technology can be shared openly with the public, so that whoever wants to can log on and study a fossil or other specimen up close...

Chinese Researchers Validate Effectiveness of Teenager’s 3D Printed Custom Knee Joint Replacement Prosthesis

When the cells in a person’s bone divide uncontrollably, a mass of invasive tissue, better known as a tumor, develops. While most bone tumors are benign, malignant forms occur most frequently in adolescent/young adult populations. Osteosarcoma is most often sited in the knee or upper arm, and tumors have a high potential to spread, potentially... Read More »
