FLUID 3D printed automation system [Source: EurekaAlert] This week’s selection is the Flowing Liquid Utilizing Interactive Device by researchers at Hokkaido University. There’s been considerable interest in developing new materials by institutions worldwide. While the development of a new and useful material can be game-changing for industry, it can take huge efforts to sort through the endless possibilities to discover the optimal combination of ingredients. Traditionally, this has been done manually, but with the advent of AI and other generative systems, the demand for automation of this process has never been higher. To reduce some of the work, researchers have developed an open-source robot that can automate material synthesis. They call it “FLUID”, for “Flowing Liquid Utilizing Interactive Device”. The system includes a large number of 3D printable parts that can be produced on inexpensive equipment. The researchers explain in their paper’s abstract: > “Here, the development of FLUID, an open-source, 3D-printed robotic platform for material synthesis, is presented. FLUID provides a comprehensive blueprint for both hardware and software, enabling accessible and customizable automation for a broad range of researchers.” As they mention, this is not so much a completed system, but rather a customizable solution that can be adapted for a variety of material synthesis operations. What’s in the system? They explain: > “FLUID’s hardware comprises four independent modules, each equipped with a syringe, two valves, a servo motor for valve control, and a stepper motor to precisely control the syringe plunger. Each module also has an end-stop sensor to detect the syringe’s maximum fill position. These modules are connected to microcontroller boards that receive commands from a computer via USB. The system also includes software that lets users control the robot’s functions, such as valve adjustments and syringe movements, and provides real-time status updates and sensor data.” Future versions of the system will incorporate additional sensors, including pH, temperature, and more. Not only will FLUID speed up the automation, but it will also lower the cost of material discovery by removing a considerable amount of labour. Ultimately, this will result in new materials becoming available for use by industry and perhaps even additive manufacturing. Via EurekaAlert and ACS **Share this post:** ________

High speed 3D printed drone [Source: Cults] This week’s selection is the 400kph drone by Cults contributor DAVE_C_FPV. Drones are a popular area of activity for 3D printer operators. Many people design their own drones and can produce the necessary parts using 3D printers. The technology is particularly useful to make parts that have unusual geometries to lower weight and increase strength. Among the countless drone designs available online, there is one that is a bit different from the rest. The “400KMH SPEED DRONE” is a rocket-like design that can literally reach the incredible flight speed of 400km/hr (250mph). 3D printed drone CAD view [Source: Cults] The project includes files for most of the structural components of the drone, although you will need a carbon fiber subframe, as they explain: > “This build requires a CNC-cut carbon subframe for structural integrity. Please use the .dxf to get it cut from 6mm carbon plated.” Of course, you will also need the motor, batteries, electronics, radio, etc., as one would expect in a drone. The remaining parts can be 3D printed in “basic PLA”, which is surprising given the extreme nature of this drone. You can certainly print the parts in other suitable materials, such as ULTEM, if you have access to machines that can use them. 3D printed drone flight view with speed at the bottom [Source: Cults] Does this drone actually fly that fast? DAVE_C_FPV posted a short video taken in flight, and as you can see, the drone actually exceeded 400kph and reached an incredible 416kph. In the video, the acceleration was ridiculously, achieving that speed in only seconds. This is certainly an incredible project, but there is a caution: > “This is an advanced FPV build and not recommended for beginners. Flying a drone this fast requires some experience, but if you’re up for the challenge, it’s an absolute blast!” That’s absolutely true: a 400kph projectile can be extraordinarily dangerous. Be careful with this one! Via Cults **Share this post:** ________
