Impresión 3D para UAVs impresionantes


Una de las tecnologías de fabricación de UAVs que están experimentando un mayor crecimiento en estos últimos años es la Impresión 3D, que está demostrando dia tras día su capacidad de aportar múltiples beneficios en lo que se refiere a la fabricación de series cortas de piezas, aptas para uso final.


Entre algunas de sus mayores ventajas se encuentra la versatilidad, ya que una sola impresora es capaz de producir infinidad de productos muy realistas hechos totalmente a medida, aportando a los departamentos de diseño una amplia flexibilidad y personalización en su trabajo.


En este webinar abordaremos los factores clave a la hora de obtener piezas de UAVs para coleccionismo que ofrezcan un aspecto similar al producto final.  Un webinar dirigido a todos aquellos fans de los UAVs a escala que quieran descubrir todas las facilidades que puede aportarles la impresión 3D en la fabricación de sus réplicas, y conocer las claves para obtener un UAV totalmente realista.

Additive manufacturing in UAVs: Challenges and potential


UAVs (Unmanned Aerial Vehicles) are gaining popularity due to their application in military, private and public sector, especially being attractive for fields where human operator is not required.

Light-weight UAVs are more desirable as they have better performance in terms of shorter take-off range and longer flight endurance. However, light weight structures with complex inner features are hard to fabricate using conventional manufacturing methods.

The ability to print complex inner structures directly without the need of a mould gives Additive Manufacturing (AM) an edge over conventional manufacturing. Recent development in composite and multi-material printing opens up new possibilities of printing lightweight structures and novel platforms like flapping wings with ease.

This paper explores the impact of additive manufacturing on aerodynamics, structures and materials used for UAVs. The review will discuss state-ofthe-art
AM technologies for UAVs through innovations in materials and structures and their advantages and limitations. The role of additive manufacturing to improve the performance of UAVs through smart material actuators and multi-functional structures will also be discussed.

Additive manufacturing techniques for millimeter-wave components


Additive Manufacturing technology has made significant advances in terms of materials, tolerances, and surface finishes.

The technique is becoming more common in science and industry. Since it has proven effective in constructing small parts with fine features, 3D Printing is well suited for improving upon the manufacturing processes of millimeter-wave components.

This paper explores the approach specifically applied to waveguide components produced using two different additive manufacturing approaches. Work is also being done to fabricate parts via additive manufacturing techniques in-house at General Atomics.

AUHSD Teams with Tesla Foundation for UAS Education


The Anaheim Union High School District (AUHSD) is the first public school district in the nation to partner with the Tesla Foundation to provide students with training to successfully work in the emerging technology field of unmanned aviation, or drones.

A nonprofit science and technology think tank, the Tesla Foundation is launching its initiative beginning at Magnolia High School with after-school programs featuring FAA (Federal Aviation Administration) approved curriculum, equipment, and Drone Flight Simulation Kits.

The foundation’s goal is to identify and develop a “farm system” of young talent that can be future innovators and entrepreneurs in the unmanned systems industry. “We are excited to partner with the District in this most critical endeavor,” said Keith Coleman, chief strategy officer of the foundation. “Our focus is looking at the future of jobs and the future of work. Automation and the disruption that it will bring is real, yet while jobs will be lost, there will be lots of new opportunities in the (new) field of aerial robotics. Through this partnership, we will help move the needle forward for underrepresented students who may not otherwise have a pathway to these experiences. The Tesla Foundation sees critical thinking and access to technology as the democratization of opportunity.”

Trustee Al Jabbar thanked Superintendent Mike Matsuda for making the connection that led to the partnership. He also thanked the Tesla Foundation for “recognizing that AUHSD is at the cutting edge in preparing students for the 21st Century workforce. Once parents and the community learn about how this partnership promotes innovation, creativity, and entrepreneurship in an emerging STEAM field, I know they will be as enthusiastic as we are.” The Tesla Foundation estimates that the economic impact of drones will be $82 billion within the first decade of their operational integration into the national airspace system. Drone industries leverage many key technologies, including cybersecurity, sensors, data analytics, aeronautics, aviation, Additive Manufacturing, precision agriculture, first responders, geospatial information, and simulation.

Additive Manufacturing for the Drone/UAV Industry 2017-2027


In this report, the firm Research and Markets projects that the yearly value of Additive Manufacturing (AM) in the UAV (Unmanned Aerial Vehicle) industry to reach $1.9 billion, driving over $400 million in yearly sales of AM equipment, software, materials and services.

The Drone AM report also provides information on which companies and institutions in the space infrastructure industry are using additive manufacturing today, with relevant case studies. Key firms in the drone AM segment include: Boeing, CRP Group, DJI, EHANG, EOS, General Atomics, HP, Hubsan, Lockheed Martin, Northrop Grumman, Oxford Performance Materials (OPM), Parrot, Ricoh,  Stratasys, 3D Systems and 3DR.

The report includes an in-depth analysis of the materials used for drone AM prototyping and production, which takes into consideration both high performance polymers and metals as well as composites, ceramics and technologies for direct 3D printing of electronics.

Marines take 3D printed UAVs from the lab to the field


Additive manufacturing is a technology the U.S. military has been pursuing for some time: “Imagine being in a forward deployed environment, and just like Amazon, you can ‘order’ the weapons and equipment you need for the next day’s mission from an entire catalog of possible solutions,” says Capt. Chris J. Wood, who oversees innovation efforts at the Marine Corps’ installations and logistics branch. “These solutions can all be upgraded literally overnight, in order to integrate new components or adapt to new requirements.”

In the coming weeks the service will deploy a tiny unmanned aircraft dubbed the “Nibbler,” which would become the first 3D printed drone used in combat operations by conventional forces. Marines see it as just the beginning of a new way of equipping and supplying forces in the field. The Nibbler will be used for surveillance missions, along with several other 3D printed unmanned aircraft that the Marines are still developing, Wood added. “We can have a backpack-able fixed wing UAS for long endurance ISR. We can have a small quadcopter for building clearing operations,” he said. “We will forward deploy these capabilities into a combat zone as soon as possible.”

Achieving ship's mission flexibility through designing, printing and operating unmanned systems with additive manufacturing and delayed differentiation


The Design, Print and Operate (DPO) Concept Of Operations (CONOPS) is proposed in this thesis as a new means of equipping ships with the appropriate capabilities. A companion concept of delayed differentiation is also introduced. In coupling the two concepts, Additive Manufacturing (AM) of capabilities in-situ becomes a possibility through the equipping of operational units with three building blocks: additive manufacturing systems and their raw materials, commercial off-the-shelf items and field programmable gate arrays.

A concept of operations on uses of additive manufacturing was developed to illustrate the flexibility that the nexus of DPO CONOPS and delayed differentiation can engender. A tactical UAV (Unmanned Aerial Vehicle) was used as an illustration to contextualize the concept of operations to enhance the littoral combat ship's survivability when operating in the littorals. Assessments were then made on the feasibility of DPO CONOPS for shipboard uses. A tactical UAV was used as it was assessed to be operationally relevant and significant. Analytical models that could be iterated to achieve the specific-to-mission requirements were developed to analyze and assess the implementation approach. The models focused on the UAV's reliability in fulfilling the mission as well as the build-time of the UAV.
