new Many parallel trends have advanced the open-source hardware movement over the last decade, including progress towards inexpensive and (mostly) reliable 3D printing. In keeping with the project’s ethos of accessibility, we use a $100 Ender 3 for the rails and you can download that printable stl file directly from Tinkercad. Tinkercad is such a beginner-friendly tool that students are asked to create a mounting bracket as part of the Lux/LDR calibration lab. This directly parallels our ever increasing use of 3D prints for equipment installations on the research side of the project. — Underwater Arduino Data Loggers, 13h ago

new But the brain is a difficult place to explore, and specialized tools are needed to learn its secrets. Lex Kravitz, from Washington University, and Mark Laubach, from American University, are neuroscientists who’ve learned that sometimes you have to invent the tools of the trade on the fly. While exploring topics as wide-ranging as obesity, addiction, executive control, and decision making, they’ve come up with everything from simple jigs for brain sectioning to full feeding systems for rodent cages. They incorporate microcontrollers, IoT, and tons of 3D-printing to build what they need to get the job done, and they share these designs on OpenBehavior, a collaborative space for the open-source neuroscience community. — Hackaday, 19h ago

new Before I embed the video below and break down some of the most pertinent information gained from it, I do want to make a disclaimer. While 3D printing underwater sounds a little silly, there are some actual benefits incurred with doing the process underwater. Cooling fans are no longer required to dissipate heat, which can lead to higher-quality prints. — Tom's Hardware, 22h ago

new OLED TVs are amongst the best TVs available, but what is an IJP OLED? Simply put, it is a method of manufacturing OLED TVs using inkjet-printing technology that could cut production costs compared to expensive current manufacturing methods. In turn, this will hopefully mean cheaper OLED prices for consumers. The panel also promises less energy consumption, resulting in a greener, more cost effective running of OLEDs, and it also suggests much brighter images. — TechRadar, 1d ago

new TATAMI ReFAB PROJECT by HONOKA (Japan) Tatami mats often remind us of Japan because they have been an essential part of almost every Japanese family in the past. However, with the culture changed, the demand for tatami mats has been dropping in recent years. Bringing back tatami mats into every Japanese home is HONOKA's goal. Traditional tatami mats are made from plants that are fragrant and have the ability to adjust humidity and reduce odours. Igusa grass from discarded mats are crushed and mixed with cellulose acetate to create a new material which, added with 3D printing, can be turned into household essentials like tables, chairs and lampshades so as to "re-embed" in Japanese homes. HONOKA has found a way to keep tatami mats alive and to pass the Japanese culture to future generations. deTour 2023 invites visitors to appreciate these furniture and items that have perfectly combined Japanese culture with the 21st-century technologies. — SME Business Daily Media, 1d ago

new Integrating the electronics with soft artificial suckers and arm segments took insight and perseverance. The team had to carefully map the predicted strains during motion and locate the circuits accordingly. Brittle links between rigid integrated circuit chips and the surrounding rubbery matrix caused early difficulties. However, numerical optimization and a liquid metal printing technique gradually overcame connection challenges without sacrificing sensing capabilities. — nanowerk.com, 1d ago

new FBX files are mostly used in animation and gaming engines like UE4 and Unity. OBJ files, on the other hand, store basic 3D model data like geometry, faces, color, and textures, but they don't support animation, lighting, and rigging data like FBX. Most CAD programs support it, and it is a file format mostly used in 3D printing, like STL files. So if you have one of the best 3D printers, especially the ones that support multi-color 3D printing, and you have an FBX file, you can convert it to OBJ to 3D print. In addition to 3D printing purposes, you can also convert FBX to OBJ if you just want a small file with simple geometries and you want to work with the meshes. This simplicity makes OBJ files smaller than FBX files. Below are the main tools to use to convert FBX files to OBJ. — Tom's Hardware, 2d ago

new The functionality of the adhesive can be increased through chemical synthesis. It can be modified to react to light, so that it hardens when exposed to UV rays.

new Integrated optical signal distributing, processing, and sensing networks require the miniaturization of basic optical elements, such as waveguides, splitters, gratings, and optical switches. To achieve this, fabrication approaches that allow for high-resolution manufacturing are required. Curved elements like bends and ring resonators are especially challenging to fabricate, as they need even higher resolution and lower sidewall roughness. Additionally, fabrication techniques with precise control of absolute structure dimensions are imperative.Several technologies have been developed for subwavelength high-resolution manufacturing, such as direct laser writing, multi-photon lithography, electron beam lithography, ion beam lithography, and domino lithography. However, these technologies are costly, complex, and time-consuming. Nanoimprint lithography is an emerging replication technique well-suited for high-resolution and efficient manufacturing. However, it requires high-quality master stamps, which are usually produced using electron beam lithography.In a new paper published in Light: Advanced Manufacturing, scientists Dr.-Ing. Lei Zheng et al. from the Leibniz University Hannover have developed a low-cost and user-friendly fabrication technique, called UV-LED-based microscope projection photolithography (MPP), for rapid high-resolution manufacturing of optical elements within seconds. This approach transfers structure patterns on a photomask to a photoresist-coated substrate under UV illumination.The MPP system is based on standard optical and optomechanical elements. Instead of a mercury lamp or a laser, an extremely low-cost UV-LED with a wavelength of 365 nm is used as the light source.The researchers developed a preceding process to obtain the structure-patterned chromium mask required in MPP. It includes structure design, printing on a transparent foil, and the pattern transfer onto the chromium photomask. They established a lithography setup for the preparation of photomasks as well. Structure patterns printed on the transparent foil can be transferred to a chromium photomask with this setup and a subsequent wet-etching process.The MPP system can fabricate high-resolution optical elements with feature sizes down to 85 nm. This is comparable to the resolution of much more expensive and complex fabrication methods, such as multi-photon and electron beam lithography. MPP could be used to fabricate microfluidic devices, biosensors, and other optical devices.This fabrication approach developed by the researchers is a significant advancement in the field of lithography for the rapid and high-resolution structuring of optical elements. It is particularly well-suited for applications where rapid prototyping and low-cost fabrication are important. For example, it could be used to develop new optical devices for biomedical research or to prototype new MEMS devices for consumer electronics applications. — newswise.com, 2d ago
