Additive Manufacturing (AM) is a rapidly developing set of methods with lots of benefits. This technology promises fast, cheap and lightweight fabrication for antennas and waveguides. Different AM technologies such as Fused Filament Fabrication (FFF), Stereolithography (SLA), Material Jetting and Powder Bed Fusion are used to fabricate antennas operating at various frequency bands and provide desirable results. To test the feasibility of the AM technologies for antenna manufacturing and also durability under military environmental conditions, a specific antenna has been modeled and fabricated via FFF, SLA and Metal-FFF type of 3D printers. The FFF and SLA fabricated antennas are electroplated with copper. Thereafter, the radiation parameters of the antennas are measured. The accordance of measurement results with the simulations and the CNC machined pair have been inspected. Afterwards, the antennas are tested according to the MIL-STD-810H environmental condition test standard. It is concluded that all additively manufactured antennas are compatible with the results of the simulations. However, additively manufactured antennas failed in some environmental condition tests. Therefore, it is suggested that the fabricated antennas do not have satisfactory features to operate in military environmental conditions.

Simulator of an additive and subtractive type of hybrid manufacturing system Dilberoğlu, Mecid Uğur; Yaman, Ulaş; Dölen, Melik (2019-06-24) Additive Manufacturing (AM) facilitates the production of intricate objects despite its weakness in attainable part quality and fabrication speed compared to the conventional manufacturing methods. To alleviate the problems arising as a natural outcome of AM methods, hybrid technologies become viable options by employing concurrent manufacturing procedures, e.g. synergetic additive and subtractive manufacturing (SM) actions. Hybrid workstations have recently opened up new dimensions to 3D-printing industry,...
A Cloud Manufacturing Application for Additive Manufacturing Methods Haseltalab, Vahid; Yaman, Ulaş (2019-01-01) Over the past years, the manufacturing industry has witnessed a great enhancement in the field of Additive Manufacturing that allows forming an inchoate market to produce custom-made products with low unit costs. At the same time, everyone may be a designer as well. However, the required equipment is only accessible for all the people. The Cloud Manufacturing aims to resolve this challenge by connecting the customers to the manufacturers. Therefore, this paper introduces a practical fabrication method for 3...
Effect of annealing on the mechanical properties of pla parts produced by fused filament fabrication Aydın, Sencer; Özerinç, Sezer; Department of Micro and Nanotechnology (2021-9-01) Additive manufacturing has become a disruptive technology for the production of load bearing components in a wide range of applications. Fused filament fabrication (FFF) is among the most effective and economical techniques for the printing of polymeric parts. There are numerous thermoplastic materials suitable for FFF. Among these, Polylactic acid (PLA) is a renewable, sustainable and cost-effective alternative. For better utilization of PLA parts produced by FFF, there is a need to understand the structur...
Use of a nozzle with a rectangular orifice on a hybrid FFF system Gharehpapagh, Bahar; Dilberoğlu, Mecid Uğur; Dölen, Melik; Yaman, Ulaş (2021-11-01) Fused Filament Fabrication (FFF) process has lower surface roughness quality, precision and it takes longer to fabricate compared to the conventional manufacturing operations and some additive manufacturing technologies. In order to overcome these issues, a rotary extruder head with a nozzle having a rectangular orifice has been utilized in this work. A new tool path planning for a rectangular nozzle is designed to increase the efficiency of the extrusion process by this nozzle. As a result, finer features ...
