![]() ![]() Now we just need someone to design the ISRU ingot production hardware and test on the Moon. Use it as a starting point for how to get to the production of ingots for use in a 3D printer. Now all we need is the tech to produce the 3D printer alloy ingots from lunar regolith or asteroid sources.īTW this is an interesting article that metions regolith processing using lower temps and a fluorine process to produce O2, Fe, Al, Ti, SI, and other byproducts that can then be more easily seperated in pure or nearly pure form. ![]() Considering that almost all the space metallic objects are of some type of aluminum or titanium alloy this technology is significant for ISRU ultimate utilization. Your mention of a 3D printer using titanium reminds me of the fact that the lunar regolith has high concentrations of titanium.Ī 3D titanium or a 3D aluminum printer could turn regolith once it has been refined and turned into ingots usable by the printers into anything. "McAlpine believes that 3D printing, with its ability to deliver a third dimension, will be used to manufacture "things that people haven't imagined yet, like structures that could be used in the body." "and his team made the LEDs using a custom 3D printer which took them six months and nearly $20,000 to assemble." Princeton Research Team 3D Prints LED Lights Indeed, this is the first time to our knowledge that semiconducting nanoparticles have been 3D printed, and the first time that such a broad array of diverse functional materials have been fully interwoven entirely using a 3D printer.”Ī 2nd article has come out on this subject and fills in some blanks. “This work outlines an exciting breakthrough that enables the direct printing of functional, embedded, active 3D nanoelectronics using only a 3D printer. "To further demonstrate the possibilities of their process, the Princeton researchers were even able to print the QLEDs onto a contact lens." We show that we can print interwoven structures of quantum dots, polymers, metal nanoparticles, etc, to create the first fully 3D printed LEDs, in which every component is 3D printed.” In our latest research, we go way beyond that. “The big push in 3D printing these days is to try to print two or more polymers at once. ![]() "A team of scientists at Princeton University have made a breakthrough in the 3D printing of functional electronic components" Princeton 3D Prints Breakthrough Quantum Dot LEDs Quote from: bolun on 11:35 am 3D-printed deployment mechanism More than 350 experts from across Europe came together to discuss the potential of 3D printing to transform the space industry and begin preparing common standards for its use. The device was on show this week during ESA’s Additive Manufacturing for Space Applications workshop at its ESTEC technical centre in Noordwijk, the Netherlands. The spiral hinges in the foreground cannot be produced as a single part in any other way. The 3D-printed version slashes the number of separate parts needed and reduces its mass by 80%. ![]() This prototype titanium version, by Thales Alenia Space, is called the Adel’Light, being a lightweight version of their existing Adele mechanism. The results were validated using commercial CFD and it can be shown that the result are satisfactory with error approximately of 6%.While this might look like a postmodern sculpture, this weirdly organic design is actually a 3D-printed deployment mechanism for satellite solar panels. For this purpose Genetic Algorithm (GA) was applied as optimizer. Moreover, the optimization was conducted to obtain an airfoil geometry which gives maximum lift to drag ratio ( C L/ C D) for specific Reynolds number. Therefore, lift and drag coefficients can be directly determined only by giving the airfoil geometry without having to perform wind tunnel experiment or numerical computation. In present study, the ANN training was conducted using airfoil geometry and its aerodynamic characteristics as input and output, respectively. First, several airfoil geometries were generated through transformation of complex variables (Joukowski transformation), and then lift and drag coefficients of each airfoil were determined using CFD (Computational Fluid Dynamics). output of model wind turbines, eg the number or pitch of the blades. Another design for an absurdly large 50 MW turbine calls for a blade length of 200 meters. Autodesk has a number of applications, 123D Design is a typical 3D modelling piece. The UpWind Project drew up plans for a massive 20 MW turbine with 123 meter long blades and a rotor diameter of 252 meters. In this work, a simulation of Artificial Neural Network (ANN) for determining the relation between airfoil geometry and its aerodynamic characteristics was conducted. Ambitiously large turbines are being designed as we speak. This paper deals with an alternative design method of airfoil for wind turbine blade for low wind speed based on combination of smart computing and numerical optimization. ![]()
