3D Printing Metals Onto Fabric for Inexpensive Antenna, Sensors and Wearables

A group of researchers from Imperial College London has developed a technique for 3D printing metals such as silver, gold and platinum onto natural fabrics. The process could also be used to incorporate batteries, wireless technologies and sensors into paper and cotton textiles. These technologies could have several applications, including new low-cost medical diagnostic tools, wirelessly... Read More »

3D Printed Electrodes Make Microfluidic Devices Cheaper and Quicker to Fabricate

Researchers at Imperial College London wanted to develop a microfluidic biosensor for analysis of cancer cells that was quicker and easier to produce. A microfluidic device involves biological material traveling through tiny channels and electrodes passing electrical current through the material so that a microchip can analyze what the material contains. The Imperial College London scientists... Read More »

TU Delft Researchers Discuss Microstructural Optimization for 3D Printing Trabecular Bone

Trabecular bone, also known as spongy or cancellous bone, is one of two types of bone found in the human body. It is found at the end of long bones, in the pelvic bones, ribs, skull and vertebrae. Trabecular bone is one of many microstructures with spatially varying properties found in nature. In a paper... Read More »

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...
