The successful application of 3D printing in aerospace industry
3D printing in the aeronautic industry: JCR 1000 saves costs
Sealant Support Tool for the Aeronautical Sector
CATEC (Center for Advanced Aerospace Technologies) has designed and developed a robotic aeronautic sealingtool, for sealing the edges of carbon fiber parts, and for aerodynamic and threadsealing.
The pieces made in FFF with JCR 1000 include the supports for the profilometers used to check the quality of the thread sealant, and the main parts of the nozzle designed to apply the sealant.
One of the main features of the nozzle is that it is designed to use disposable cartridges, so that the parts that have contact with the sealing do not need any maintenance. The main function of these parts is to calibrate application and perform some initial tests before machining the end pieces, in order to ensure that the tool is robust and to achieve a pneumatic seal.
Life-size Aircraft Turbine Model
This 1:1 scale model of an aircraft turbine was created by the R&D department of Grupo Sicnova, which designed it from scratch, based on an analysis of the technique used for real turbines, employed in the aeronautical sector.
The process consists of several phases: design, manufacture using 3D printing, assembly and a final post-processing phase.
Once the 3D design of the whole turbine had been completed and checked, it was divided into fifty pieces, including the blades, with a system to join the different parts together with screws. The parts are made entirely from additive manufacturing, using about 100 kg of black PLA.
A metal chassis has also been designed to support the weight of the turbine (about 110 kg) and to facilitate transportation. Once assembled, the turbine is 2215mm long and has a diameter of 1200mm.
The final post-processing stages of caulking, painting and polishing the piece are completed to ensure a good finish.
Latticework and Support for the Electromagnet in an Aerospace Prototype
The Center for Advanced Aerospace Technologies (CATEC)has used the FFF technology of the JCR 1000 on various projects in the aerospace sector. In this particular case, it has been used to manufacture a lattice which has been placed into the slides of a multirotor, specifically in the lowest part, almost touching the ground, to hold the electromagnets and an altimeter laser.
The multirotor, along with the latticework, has been used in experiments carried out as part of the ‘Mohamed Bin Zayed International Robotics Challenge’ (MBZIRC), which is currently the largest international robotics competition in the world, with 5 million USD in sponsorships and prizes. In the MBZIRC, the latest scientific and technological achievements in robotics are applied in three “Challenges” and a “Grand Challenge” which combines all three of them.
