OAKLAND, Calif. — A Bay Area design technologist is using 3D printing and calcium carbonate to help restore coral reefs and marine biodiversity that has been impacted by climate change.
Coral reefs are currently threatened by pollution, overfishing, and climate change.
According to SECORE International, fifty-percent of the world’s coral reefs have died in the past three decades. Ninety-percent of coral reefs could die within the next century.
Phrozen’s latest MSLA Resin 3D Printer comes with an 8K resolution mono LCD panel and can print up to 400mm high! But, should you choose this beast over several smaller printers instead?
A team of researchers from TU braunschweig in germany has developed a new method of 3D printing concrete that shows potential for more complex 3D printed structures. currently, 3D printed concrete construction focuses on three methods, material extrusion, particle-bed binding, and jetting, all of which apply the concrete in horizontal layers. unlike these layered techniques, injection 3D concrete printing (I3DCP) consists of robotically injecting a fluid material into another material with specific rheological properties, in other words, how the material responds under force or stress. free from gravity, injecting allows more complex structures to be printed in one piece.
10 more 3D printed tools, which could be useful to you. You can buy this kind of tools from store, but why not to 3d print them.
Chinese 3D printer manufacturer Creality has announced the launch of a cost-effective yet highly-capable new 3D scanner.
Known as the ‘CR-Scan 01,’ Creality’s latest entry into the scanning market is easy-to-use but features high-end specifications, and is able to capture details down to 0.1mm in size. Thanks to its adjustable modes, multi-pose alignment and enhanced scanning width, the system ultimately allows designers to recreate anything from small items to furniture, with impressive simplicity, affordability and precision.
According to Creality, the increasing popularity of VR and AR technologies has created a rising demand for scanners that are easy to operate, yet capable of capturing the data needed for producing quality models. To address this perceived demand, the company says that it has developed a new UI to make the CR-Scan 01 so user-friendly, that it’s “as simple as a fully-automatic washing machine.”
When The Simpsons first appeared, we were all watching it on CRT televisions, many of which probably weren’t widescreen. Oh how times have changed, but someone has created the classic Simpsons viewing experience using a miniature reproduction of the famous family’s own TV.
Reddit users buba447 posted a video of his replica Simpsons TV, which looks exactly like the TV found in the cartoon family’s home. It uses a 640-by-480 TFT panel and is housed in a 3D-printed casing. Inside is a Raspberry Pi Zero running Jesse Lite and a 32GB SD card containing 11 seasons of the show to watch.
This stunning Raspberry Pi Pico macro keyboard features 17 keys, two encoders, an IPS screen, and a 3D-printed enclosure.
The keyboard/mouse combo has worked well for many years, but with the availability of HID-capable microcontrollers, 3D printing, and custom-made circuit boards, it’s possible to buy or construct your own third interface device: a macropad. These auxiluary keyboards can be programmed to do all sorts of tasks in an instant that cost you precious seconds before. Some even include an encoder (or two) and perhaps an auxiliary interface screen.
The company will begin mass production in 2022
Something to look forward to: Solid-state batteries are still nebulous outside of the lab. Still, automakers are scrambling to be the first in the race to build the first electric car to take advantage of the added energy density and better safety when compared to lithium-ion designs. To that end, they’re investing in companies like QuantumScape, Solid Power, and Sakuu to develop manufacturing techniques that either build on existing approaches or rely on new additive manufacturing technology.
Surface-mount technology has been a fantastic force multiplier for electronics in general and for hobbyists in particular. But sometimes you’ve got no choice but to use through-hole components, meaning that even if you can take advantage of SMDs for most of the design, you still might need to spend a little time with soldering iron in hand. Or not, if you’ve got a spare 3D printer lying around.
The U.S. Army has built and fired an almost entirely 3D-printed 40mm grenade launcher. Scientists and engineers hope the prototype will set the stage for projects in the laboratory and on the battlefield.
The Armament Research, Development and Engineering Center (ARDEC) at Picatinny Arsenal in New Jersey modeled the proof-of-concept Rapid Additively Manufactured Ballistics Ordnance (RAMBO) on the Army-standard M203 grenade launcher and marked it “M203XX.” The production process for 90 percent of the components was at least partially automated, though engineers had to assemble the final weapons by hand. Certain springs and fasteners were too small and complex for a 3D printer. The project also produced training rounds based on the M781, but engineers had to manually add the explosive propellant right before the test shots.
