Reinventing metal 3D printing with direct metal writing process

Reinventing metal 3D printing with direct metal writing process
Posted: Mar 30, 2017 (Nanowerk News) Metal 3D printing has enormous potential to revolutionize modern manufacturing. However, the most popular metal printing processes, which use lasers to fuse together fine metal powder, have their limitations. Parts produced using Selective Laser Melting (SLM) and other powder-based metal techniques often end up with gaps or defects caused by a variety of factors. To overcome those drawbacks, Lawrence Livermore Natio…

3-D bioprinted human cartilage cells can be implanted

3-D bioprinted human cartilage cells can be implanted
Posted: Mar 23, 2017 (Nanowerk News) Swedish researchers at Chalmers University of Technology and Sahlgrenska Academy have successfully induced human cartilage cells to live and grow in an animal model, using 3D bioprinting. The results will move development closer to a potential future in which it will be possible to help patients by giving them new body parts through 3D bioprinting. The results were recently presented in the journal Plastic and Recon…

Dramatic improvement in surface finishing of 3-D printing

Dramatic improvement in surface finishing of 3-D printing
Posted: Mar 13, 2017 (Nanowerk News) Waseda University researchers have developed a process to dramatically improve the quality of 3D printed resin products. The process combines greatly improved surface texture and higher structural rigidity with lower cost, less complexity, safer use of solvent chemicals and elimination of troublesome waste dust. A shows a printed surface with no smoothing; B is first step using the pen to d…

3-D printing with cellulose

3-D printing with cellulose
Posted: Mar 03, 2017 (Nanowerk News) For centuries, cellulose has formed the basis of the world’s most abundantly printed-on material: paper. Now, thanks to new research at MIT, it may also become an abundant material to print with — potentially providing a renewable, biodegradable alternative to the polymers currently used in 3-D printing materials. “Cellulose is the most abundant organic polymer in the world,” says MIT postdoc Sebastian Pattinson, le…

3D printing with high-performance aerospace-grade carbon fiber (w/video)

3D printing with high-performance aerospace-grade carbon fiber (w/video)
Posted: Feb 28, 2017 (Nanowerk News) Lawrence Livermore National Lab researchers have become the first to 3D print aerospace-grade carbon fiber composites, opening the door to greater control and optimization of the lightweight, yet stronger than steel material. The research, published by the journal Nature Scientific Reports represents a “significant advance” in the development of micro-extrusion 3D printing techniques for carbon fiber, the authors re…

Most stretchable elastomer for 3-D printing

Most stretchable elastomer for 3-D printing
Posted: Feb 09, 2017 (Nanowerk News) Due to its excellent material properties of elasticity, resilience, and electrical and thermal insulation, elastomers have been used in a myriad of applications. They are especially ideal for fabricating soft robots, flexible electronics and smart biomedical devices which require soft and deformable material properties to establish safe and smooth interactions with humans externally and internally. However, to date,…

Better 3D-printed scaffolds help scientists study cancer

Better 3D-printed scaffolds help scientists study cancer
Posted: Feb 08, 2017 (Nanowerk News) Testing treatments for bone cancer tumors may get easier with new enhancements to sophisticated support structures that mimic their biological environment, according to Rice University scientists. A team led by Rice bioengineer Antonios Mikos has enhanced its three-dimensional printed scaffold to see how Ewing's sarcoma (bone cancer) cells respond to stimuli, especially shear stress, the force experienced by tumors …

Mimicking nature's cellular architectures via 3D printing (w/video)

Mimicking nature
Posted: Feb 07, 2017 (Nanowerk News) Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being compressed. The plant’s hardiness comes from a combination of its hollow, tubular macrostructure and porous, or cellular, microstructure. These architectural features work together to give grass its robust mechanical properties. Inspired by n…

Scientists create a 3-D bioprinter to print human skin (w/video)

Scientists create a 3-D bioprinter to print human skin (w/video)
Posted: Jan 23, 2017 (Nanowerk News) This research has recently been published in the electronic version of the scientific journal Biofabrication ("3D bioprinting of functional human skin: production and in vivo analysis"). In this article, the team of researchers has demonstrated, for the first time, that, using the new 3D printing technology, it is possible to produce proper human skin. One of the authors, José Luis Jorcano, professor in UC3M's department of Bioengi…
