Creality’s Economical New ‘CR-SCAN 01’ 3D Scanner

August 25, 2021 by CrackedConsole

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.”

Sakuu’s 3D printed solid state battery could be a boon for electric vehicles

August 21, 2021 by CrackedConsole

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.

Google says it has created a time crystal in a quantum computer, and it’s weirder than you can imagine

August 9, 2021 by CrackedConsole

In what could be the first useful application of quantum computing, Google’s scientists have demonstrated the existence of a new phase of matter.

In a new research paper, Google scientists claim to have used a quantum processor for a useful scientific application: to observe a genuine time crystal.

If ‘time crystal’ sounds pretty sci-fi that’s because they are. Time crystals are no less than a new “phase of matter”, as researchers put it, which has been theorized for some years now as a new state that could potentially join the ranks of solids, liquids, gases, crystals and so on. The paper remains in pre-print and still requires peer review.

Nicolai Valenti Developed a Budget-Friendly Metal 3D Printer

August 4, 2021 by CrackedConsole

This 3D printer allows makers to create metal parts without breaking the bank.

Nicolai Valenti created an affordable PLA metal 3D printer that allows makers to prototype metal parts. The machine relies on SS316L, copper, aluminum, and titanium powders, heated via a Nichia laser array beaming 405 nm light to produce metal parts. Overall, this is Valenti’s fourth and final metal 3D printer prototype, and it utilizes three NEMA 17 stepper motors with GT2 belts.

Was Lord Kelvin wrong? 3D-printed shape casts doubt on his 150-year-old theory

August 3, 2021 by CrackedConsole

A 150-year-old theory about an otherworldly shape proposed by Lord Kelvin, one of history’s greatest physicists, has finally been put to the test — and his conjecture is now in doubt.

In 1871, William Thomson, more commonly known as Lord Kelvin — a famed British physicist who made key contributions to electromagnetic theory, thermodynamics, navigation and the absolute temperature system that bears his name — proposed a theory about a strange hypothetical shape, which he called an isotropic helicoid.

3D Printed Material Might Replace Kevlar

August 2, 2021 by CrackedConsole

Prior to 1970, bulletproof vests were pretty iffy, with a history extending as far as the 1500s when there were attempts to make metal armor that was bulletproof. By the 20th century there was ballistic nylon, but it took kevlar to produce garments with real protection against projectile impact. Now a 3D printed nanomaterial might replace kevlar.

A group of scientists have published a paper that interconnected tetrakaidecahedrons made up of carbon struts that are arranged via two-photon lithography.

A REALLY unusual 3D Printing surface! Ultembase PEI Glass test and review.

The Ultembase from Energetic 3D is the first powder coated PEI glass print surface I’m aware of, and promises several advantages over alternatives. Let’s test it out!

Researchers Proclaim Breakthrough in Full-Color Low-Power ‘Electronic Paper’ Displays

July 27, 2021 by CrackedConsole

Taking an existing design and flipping it on its head, this new display type offers extremely low power draw yet high-quality colors.

A team from the Chalmers University of Technology claims to have made a breakthrough in sunlight-readable full-color displays, developing an ePaper display capable of “brilliant colors” — at a very low power draw.

“For reflective screens to compete with the energy-intensive digital screens that we use today, images and colors must be reproduced with the same high quality. That will be the real breakthrough,” explains Marika Gugole, doctoral student at the Chalmers University of Technology. “Our research now shows how the technology can be optimized, making it attractive for commercial use.”

Befinitiv’s Digital Film Cartridge Adds a RaspberryPi to an Old Film Camera — with Great Results

July 22, 2021 by CrackedConsole

Using a 3D-printed housing, a Raspberry Pi Camera Module, Raspberry Pi Zero, and LiPo battery, befinitiv has given an old camera a rebirth.

Pseudonymous maker “befinitiv” has shown off a Raspberry Pi-powered upgrade for film cameras, turning them into digital cameras capable of stills, video, and even live-streaming — albeit with considerably different zoom from their stock designs.

“This was state of the art 50 years ago,” befinitiv explains of a Cosina Hi-Lite film camera. “Back then, of course, you shot your films or photos on these films, and this was rather expensive back in the day — but today it’s even more expensive and a bit cumbersome.

This RaspberryPi – Based Parking Lot Monitor Detects Unauthorized Vehicles

July 12, 2021 by CrackedConsole

For a university project, Codrin used a Raspberry Pi to create a system that detects unauthorized vehicles.

The United States is a car culture and most Americans have to own a car to commute to work and get around. As a result of that fact, parking lots are everywhere. You don’t just need a parking spot for your car at home, but also at work and every other place you go. In Jackson, Wyoming, for example, there are 27.1 parking spots for every household. Despite that, private parking lots are common and owners need a way to ensure that only authorized vehicles enter the lot. For a university project, Codrin used a Raspberry Pi to create a system that detects unauthorized vehicles.
