Producing Crazy Textures by 3D Printing Clay With Custom Rotating Nozzles

Posted by in category: 3D printing

Polish artist Piotr Wasniowski is a bit of a mad scientist. An expert in 3D printed clay, Wasniowski’s tool of choice is a “Gaia Multitool Polish clay 3D printer with cheap de-airing clay extruder with rotational nozzle,” for which he fabricates his own nozzles.

These variants allow him to print a variety of crazy textures.

New 3D printing technique integrates electronics into microchannels to create flexible, stretchable microfluidic devices

Posted by in categories: 3D printing, materials

The transition from traditional 2D to 3D microfluidic structures is a significant advancement in microfluidics, offering benefits in scientific and industrial applications. These 3D systems improve throughput through parallel operation, and soft elastomeric networks, when filled with conductive materials like liquid metal, allowing for the integration of microfluidics and electronics.

Blurred Light Harnessed to 3D Print High Quality Lenses

Posted by in category: 3D printing

New 3D printing method produces commercial grade microlenses with smooth surfaces, which could advance optical device design.

Researchers in Canada have developed a new 3D printing method called blurred tomography that can rapidly produce microlenses with commercial-level optical quality. The new method may make it easier and faster to design and fabricate a variety of optical devices.

“We purposely added optical blurring to the beams of light used for this 3D printing method to manufacture precision optical components,” said Daniel Webber from the National Research Council of Canada. “This enables production of optically smooth surfaces.”

Marriage of synthetic biology and 3D printing produces programmable living materials

Posted by in categories: 3D printing, bioengineering, biological, genetics, sustainability

Scientists are harnessing cells to make new types of materials that can grow, repair themselves and even respond to their environment. These solid “engineered living materials” are made by embedding cells in an inanimate matrix that’s formed in a desired shape. Now, researchers report in ACS Central Science that they have 3D printed a bioink containing plant cells that were then genetically modified, producing programmable materials. Applications could someday include biomanufacturing and sustainable construction.

This 3D-Printer can figure out How to Print with an Unknown Material

Posted by in categories: 3D printing, sustainability

Researchers developed a 3D printer that can automatically determine the printing parameters of an unknown material. This could help engineers use emerging renewable or recycled materials that have fluctuating properties, which makes them difficult to print with.

While 3D printing has exploded in popularity, many of the plastic materials these printers use to create objects cannot be easily recycled. While new sustainable materials are emerging for use in 3D printing, they remain difficult to adopt because 3D printer settings need to be adjusted for each material, a process generally done by hand.

To print a new material from scratch, one must typically set up to 100 parameters in software that controls how the printer will extrude the material as it fabricates an object. Commonly used materials, like mass-manufactured polymers, have established sets of parameters that were perfected through tedious, trial-and-error processes.

MIT’s new 3D printer can create its own parameters so that users don’t have to

Posted by in categories: 3D printing, sustainability

A team of scientists have developed a new FDM 3D printer that can automatically create parameters for unknown materials.

Material presets for mass-manufactured polymers can be found on most 3D printers. However, the 3D printing parameters for sustainable and recycled materials need to be manually adjusted. This trial and error process can be frustrating and time-consuming, limiting the adoption of environmentally friendly filaments.

Experts from MIT’s Center for Bits and Atoms (CBA), the U.S. National Institute of Standards and Technology (NIST), and Greece’s National Center for Scientific Research (Demokritos) are working to change this.

Advanced Tech and Life Science on Station Today Promoting Health

Posted by in categories: 3D printing, bioprinting, biotech/medical, health, nanotechnology, science, space travel

Nanomaterials manufacturing, 3D bioprinting, and astronaut eye health were the main research topics aboard the International Space Station on Friday. The Expedition 71 crew members also continued servicing spacesuits and conducted an emergency drill.

The SpaceX Dragon cargo spacecraft recently delivered to the orbital outpost a biotechnology study to demonstrate the in-space production of nanomaterials that mimic DNA. NASA Flight Engineers Jeanette Epps and Mike Barratt worked on the second portion of that experiment on Thursday mixing then treating the research samples for analysis. Epps began her day mixing solutions in the Life Science Glovebox to create specialized nanomaterials. During the afternoon, Barratt applied sound and light treatments to the samples then stowed them aboard Dragon for analysis back on Earth. Results may lead to advanced therapies for space-caused and Earthbound health conditions.

The duo partnered back together at the end of the day for eye scans using standard medical imaging gear found in an optometrist’s on Earth. Barratt operated the hardware with guidance from doctors on the ground peering into Epp’s eyes and examining her retina and optic nerve for the B Complex eye health investigation.
