3D Printing

Researchers from Hyderabad in India have successfully transplanted a 3D printed cornea onto a rabbit, which will pave the way for transplants onto human patients. Read on to learn more about this world first. The researchers from Indian Institute of Technology (IIT) ,LV Prasad Eye Institute (LVPEI), and the Center for Cellular and Molecular Biology (CCMB), all located in Hyderabad, produced the cornea using natural, animal-free components. It was printed with a biomimetic ink made from human donor tissue. The researchers decellularized a human cornea tissue matrix and added some stem cells. The old cornea has lived on as the basis of a new cornea and may contribute towards treating scratched/damaged corneas, which can lead to blindness. The cornea in question (Image credit: LVPEI) “It is the first 3D printed human cornea that is optically and physically suitable for transplantation,” read a statement from researchers at LVPEI. “The bio-ink used…    read more 

Researchers from German institutes are planning to send a robotic mobile selective laser melting (SLM) printer to the Moon, to demonstrate in-situ additive manufacturing using lunar regolith as a feedstock. The project is carried out by engineers from the Hannover Laser Center (LZH) and the Berlin Technical University (TU Berlin), and the technology has already been demonstrated successfully on Earth, using simulated lunar conditions. You can see a render of the robot in the image below. Printing with moondust (Image credit: LZH) Moonrise The three-year long “Moonrise” project has received funding from the German Federal Ministry of Economics and Climate Action to the tune of 4.75 million euros ($4.82 million). It is intended to pave the way for technologies for lunar construction by using in-situ resource utilization, in this case, the resource being the silicate regolith of the Moon’s surface. Why utilize local materials? Because sending stuff to the Moon…    read more 

3D printed solid-state battery manufacturer Sakuu has opened up an innovation hub in Silicon Valley aimed at accelerating their battery printing initiatives. The company, who have developed the world’s first solid state battery, intends for the new site to serve as a blueprint for battery printing gigafactories around the world. The new 79,000 square ft facility will house battery, engineering, material science, R&D and 3D printing departments, and will oversee employee training and client product demos. 115 employees are expected to be working at the factory by early 2023, in time for the product rollout later in the year. New Sakuu gigafactory (Image credit: Sakuu) Sakuu has developed two key products that will be showcased at the new factory. The first is the company’s Kavian platform which is the world’s first large scale 3D printing platform for the additive manufacturing of custom ultra-high energy density solid-state batteries for a variety…    read more 

VisiJet M2S-HT90 High temperature & translucent VisiJet M2S-HT90 (MJP) is a strong and transparent / translucent material ideal for applications requiring temperature resistance and/or biocompatibility. It is well suited for rapid tooling, functional prototyping in warm environments, and medical devices with fine features and internal structures. This VisiJet material is fine-tuned for use with 3D Systems’ ProJet 2500 Plus MJP printer running in UHD mode. Source link 2022-08-11 19:55:53

A research paper and associated video has been published demonstrating the freeform printing of extruded thermoset plastics. The video shows a thermoset composite being extruded and curing in mid air, and without support material. It has been achieved with a process known as Frontal Polymerization, and the researchers from Colorado State University claim this is the first time that freeform printing thermoset composites with FP has been demonstrated. You can see the FP printing in action in the video below. Read on to know more about Frontal Polymerization. Thermoset The vast majority of extrusion-based carbon-fiber composite printer systems utilize feedstock consisting of short chopped fiber pieces encased within a thermoplastic matrix (the filament or pellet). This is exactly how a heat-based plastic printer works. It melts a thermoplastic with its hotend, it extrudes it, the extruded plastic cools rapidly as it leaves the nozzle, and it sets into shape. The…    read more
