3D printing conquers new branches of production due to becoming a more reliable and professional method of manufacturing. The benefits of additive manufacturing such as part optimization, weight reduction, and ease of prototyping were factors accelerating the popularity of 3D printing. Additive manufacturing has found its niches, inter alia, in automotive, aerospace and dentistry. Although further research in those branches is still required, in some specific applications, additive manufacturing (AM) can be beneficial. It has been proven that additively manufactured parts have the potential to out perform the conventionally manufactured parts due to their mechanical properties; however, they must be designed for specific 3D printing technology, taking into account its limitations. The maritime industry has a long-standing tradition and is based on old, reliable techniques; therefore it implements new solutions very carefully. Besides, shipbuilding has to face very high classification requirements that force the use of technologies that guarantee repeatability and high quality. This paper provides information about current R&D works in the field of implementing AM in shipbuilding, possible benefits, opportunities and threats of implementation.

Biomimetic robots borrow their structure, senses and behavior from animals, such as humans or insects, and plants. Biomimetic design is design ofa machine, a robot or a system in engineeringdomain thatmimics operational and/orbehavioral model of a biological system in nature. 3D printing technology has another name as rapid prototyping technology. Currently it is being developed fastly and widely and is applied in many fields like the jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industry, education, geographic information system, civil engineering, guns. 3D printing technology is able to manufacture complicated, sophisticated details that the traditional processing method cannot manufacture. Therefore, 3D printing technology can be seen as an effective tool in biomimetic, which can accurately simulate most of the biological structure. Fused Deposition Modeling (FDM) is a technology of the typical rapid prototyping. The main content of the article is the focusing on tensile strength test of the ABS-Acrylonitrile Butadiene Styrene material after using Fused Deposition Modeling (FDM) technology, concretization after it’s printed by UP2! 3D printer. The article focuses on two basic features which are Tensile Strength and Determination of flexural properties.

In order to overcome the disadvantage of traditional joint fabrication method—inability to reproduce the rough surfaces of practical rock joints—3D-printing technology was applied to restructure five kinds of rough joint according to the failure surface formed by the triaxial prepeak unloading test in this study. And uniaxial compression test was carried out on the rock-like specimens containing closed 3D-printing rough joint to study the effects of joint inclination and joint length on the mechanical properties (peak strength, peak strain, elastic modulus, and secant modulus), cracking process, and failure modes. Besides, digital image correlation (DIC) method and acoustic emission (AE) system are used to investigate the whole evolution process of strain fields and crack propagation during loading. It is found that the mechanical parameters decrease first and then go up as the joint inclination increases, while presenting a continuous downward trend with the increase of joint length. Inclination of 45° and the larger joint length bring more extensive reduction to mechanical properties of specimens. Specimens exhibit typical brittle failure characteristics. The failure mode of specimens affected by different joint inclination is tension-shear failure. And the joint scale rises; the failure mode of specimens changes from tensile failure to shear failure. Larger joint scale results in the longer prepeak fluctuation phase on axial stress-strain curves and more dispersed distribution of high-value AE counts.

Nano and micro satellites, when revolving around the earth, may drift by very small angle from their orbit. But this small angle drift may result in large deviation from their original orbit over a long distance which these satellite covers over a period of time. For the course correction of these satellites, very small thrust is required in specific direction. Normal propulsion system cannot serve this purpose, because the thrust may be too large for these satellites. That’s where the role of micro thrusters becomes important. These are MEMS devices which can produce very small thrust and can be used for nano and micro satellite propulsion. In this study, we have developed micro thrusters using 3D printing technology from ceramic polymer composite. They have been characterized for different nano mechanical properties to study their suitability for propelling the nano and micro satellite.

Design of a snap connector to connect panel elements. The aim of this study was to design, manufacture and verify the tensile strength of a prototype snap connector to be used to connect panel elements. Firstly, analyses were conducted on solutions of commercially available designs for connectors invisible from the cabinet’s outside and those with minimized visibility. While searching for the best concept of connector design, three proposals were prepared, of which – after thorough analysis of design – one concept was selected. In the next step, the adopted solution was improved so that the connector met the previously formulated design requirements. In the course of further analyses, the causes and effects of failure were verified in order to limit or eliminate potential defects. In the next stage of the study, numerical calculations were conducted for the nut and the connector, concerning tensile strength, using the Autodesk Simulation Multiphysics program. After a prototype connector was manufactured, tensile strength tests were conducted on the connector using a strength testing machine. Experiments verified the correctness of the developed design in terms of geometry and the physico-mechanical properties of materials of individual elements, and resulted in possible changes proposed in the design of the final connector product.

Carbonyl Iron Powder

Three-dimensional (3D) printing technology has proven to be a convenient and effective method to fabricate structural electromagnetic wave (EMW) absorbers with tunable EMW absorption properties. To obtain a functional material with strong EMW absorbing performance and excellent mechanical properties for fused deposition modeling (FDM) 3D printing technology, in this work, carbonyl iron powder (CIP)/acrylonitrile-butadiene-styrene copolymer (ABS) composites with different CIP contents were prepared by the melt-mixing process. The effects of the CIP content on the EMW absorption and mechanical properties of CIP/ABS composites were investigated. The CIP/ABS composite with a CIP content of 40 wt.% presented the lowest reflection loss (RL) of −48.71 dB for the optimal impedance matching. In addition, this composite exhibited optimal mechanical properties due to the good dispersion of the CIPs in the matrix ABS. Not only were the tensile and flexural strength similar to pure ABS, but the tensile and flexural modulus were 32% and 37% higher than those of pure ABS, respectively. With a CIP content of 40 wt.%, the CIP/ABS composite proved to be a novel functional material with excellent EMW absorbing and mechanical properties, providing great potential for the development of structural absorbers via FDM 3D printing technology.
