Updated software improves slicing for large-format 3D printing
Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed the first additive manufacturing slicing computer application to simultaneously speed and simplify digital conversion of accurate, large-format three-dimensional parts in a factory production setting.
The technology, known as Slicer 2, can help widen the use of 3D printing for larger objects made from metallic and composite materials. Objects the size of a house and beyond are possible, such as land and aquatic vehicles and aerospace applications that include parts for reusable space vehicles.
Slicing software converts a computer-aided design, or CAD, digital model into a series of two-dimensional layers called slices. It calculates print parameters for each slice, such as printhead path and speed, and saves the information in numerically controlled computer language. The computer file contains instructions for a 3D printer to create a precise 3D version of the image.
Tiny Titan: MIT’s Revolutionary Coin-Sized 3D Printer Fits in Your Pocket
Researchers from MIT and the University of Texas have developed a prototype for a handheld, chip-based 3D printer using a photonic chip that emits beams of light to cure resin into solid objects. This innovative technology could revolutionize the production of customized, low-cost objects on-the-go and has potential applications in medical and engineering fields.
Portable 3D Printing Technology
Imagine a portable 3D printer you could hold in the palm of your hand. The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation.
No assembly required: Innovative 3D printing method streamlines multi-materials manufacturing
University of Missouri researchers have developed a way to create complex devices with multiple materials—including plastics, metals and semiconductors—all with a single machine.
The research, which was recently published in Nature Communications, outlines a novel 3D printing and laser process to manufacture multi-material, multi-layered sensors, circuit boards and even textiles with electronic components.
It’s called the Freeform Multi-material Assembly Process, and it promises to revolutionize the fabrication of new products.
Producing Crazy Textures by 3D Printing Clay With Custom Rotating Nozzles
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
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.

Virgin Galactic Launches Crewed Galactic 07 Mission
Virgin Galactic is using its SpaceShipTwo to launch the final commercial flight of VSS Unity. This is the 17th flight of the VSS Unity, before the company plans to upgrade the vehicle.
The commercial crew on this mission is composed of a researcher affiliated with Axiom Space, two private Americans, and a private Italian. The Virgin Galactic crew on Unity will be Commander Nicola Pecile and pilot Jameel Janjua.
The ‘Galactic 07’ autonomous rack-mounted research payloads will include a Purdue University experiment designed to study propellant slosh in fuel tanks of maneuvering spacecraft, as well as a UC Berkeley payload testing a new type of 3D printing.
Expected Takeoff: 10:30 a.m. Eastern Time.

Blurred Light Harnessed to 3D Print High Quality Lenses
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
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.
