3D打印新闻简报:2020年2月4日联系下面的我们了解更多热门留言板主题:搜索2019年12月10日我们还有另一个新的播客给你!这次Max和我讨论Formnext，我(希望)能给你们带来来自前线的消息。接下来我们讨论如何巨大的形式…今天，Max和我回到了3D扫描的世界。今天的嘉宾是Anna Zevelyov，她是Thor3D的联合创始人兼首席执行官。Thor3D是一种3D扫描…今天，我们有一集是马克斯和我之间关于我们在3D打印中钦佩的人的自由讨论。首先，我们必须承认……在今天的3D打印新闻简报中，我们将涵盖一系列主题。首先，Digital Alloys分享了关于冷喷涂金属3D打印过程的指南。 UPM just launched its new GrowInk Bioinks product range. STPL3D offered its 3D printing expertise to help with a complex orthopaedic surgery, and the Smithsonian Institution is using Mimaki’s full-color 3D printer to make virus models for an exhibit. Finally, 3D printing was used to give an ancient mummy a voice…sort of. Digital Alloys’ Cold Spray Guide Massachusetts-based Digital Alloys has been publishing a Guide to Metal Additive Manufacturing , and the 16th part is all about Cold Spray technology , which was used as a coating process for many years before it was adapted into a metal 3D printing technology for rapid fabrication of near-net-shape parts . The technology uses pressurized gas to rapidly fire metal powders through a nozzle, aimed at the deposition point, with high enough velocity to create a metallurgical bond on impact but without melting the material. High-pressure Cold Spray systems allow for the processing of heavier materials, like steel and titanium alloys, while low-pressure systems use ambient air as a propellant, making them better for more ductile metals, like copper and aluminum. “Cold Spray’s advantages include compatibility with heat-sensitive materials, low thermal stresses, and the ability to operate in an open (non-inert) environment. Disadvantages include restrictive part geometry, low density and accuracy, and material embrittlement,” the blog post states. “This post provides an overview of Cold Spray metal AM technology: how it works, geometry capability, material compatibility, economics, applications, and current state of commercialization.” UPM Launched GrowInk Product Range Biomaterials company UPM , which introduced the biocomposite 3D printing material Formi 3D two years ago, is now launching a new line of hydrogels. The GrowInk 3D printing product range, which consists of non-animal derived, ready-to-use hydrogels, was introduced at the recent SLAS2020 conference. These bioinks, made up of water and nanofibrillar cellulose, support cell growth and differentiation by mimicking the in vivo environment, and are compatible with a wide range of 3D printers. GrowInk Bioinks provide excellent imaging quality, and are perfect for many different 3D bioprinting applications, such as scaffold preparation and cell encapsulation for drug discovery, regenerative medicine, and tissue engineering. Additionally, UPM is also expanding its GrowDex product range with the sterile hydrogel GrowDex-A, which was created to debind biotinylated molecules, like antibiotics and peptides. STPL3D Provides 3D Printing Help in Orthopedic Surgery In December, 14-year-old Aaska Shah from India sustained multiple fractures to her left elbow while playing, and at her young age, a prosthetic implant would only compromise her natural movements. So doctors were left with no choice but to operate, using clamps to keep the bone pieces in place. Aaska’s surgery was denied because of how complex it would be, but Dr. Jignesh Pandya took on the task, and partnered up with Agam Shah from 3D printing service STPL3D to create a 3D printed resin model of the patient’s fractured elbow bone for surgical planning. “Dr Pandya and his team first reviewed x-rays and 2D scans of the patient and reviewed their surgical plan. The doctors were a little concerned because there are a frightening amount of things that can go wrong during the operation but refused to give up hope,” an STPL3D blog post states. “The doctors have faced many challenges during the operation like deciding the clamp length and attaching points in the bone but the surgeries were successful largely thanks to the skilled surgeons.” The doctors said the 3D model gave them “greater confidence,” and the patient was also on the operation table for roughly 25% less time.
