“…These findings further support the idea of 3d printing of silicon materials as in the study of Georgopoulou et al [31] main difference in our study is that it is conductive material is embedded by extrusion of conductive silicon instead of printing with FDM. The results of the study shows similar results for the test of dumbbells using ASTM D-412 standard as carried by Miriyev et al [32]. When the two studies are compared, ıt can see that, values are found to be a match with each other.…”

With the latest technology, the development and interest in soft robots have gained speed. Flexible robots are generally produced by the casting method. This traditional production method has difficulties in the production of complex geometries such as, sharp corners, thin structures, cavities, pipelines and use of multi-materials. Also a new mold is needed for each product in the casting method and the mold costs are quite high. In additive production method, no mold is needed. Design can be produced at any time. When it comes to the production of a small number of special parts, faster production is achieved compared to the casting method. Therefore, present study aims to design and produce a multi-material 3D printer capable of printing non-conductive and conductive rapidly curing silicone that can be used in soft robotics and medical simulators. The electrical conductivity was achieved by mixing silicone and graphite powder. The parts in the printer are also produced by the additive manufacturing. Test pieces were printed using the produced 3D printer. Specific tests on produced parts produced have been carried out to determine mechanical and electrical properties. Technical data such as strength, elasticity, electrical conductivity have been obtained.

Anisotropy is the characteristic of a material to exhibit variations in its mechanical, electrical, thermal, optical properties, etc. along different directions. Anisotropic materials have attracted great research interest because of their wide applications in aerospace, sensing, soft robotics, and tissue engineering. 3D printing provides exceptional advantages in achieving controlled compositions and complex architecture, thereby enabling the manufacture of 3D objects with anisotropic functionalities. Here, a comprehensive review of the recent progress on 3D printing of anisotropic polymer materials based on different techniques including material extrusion, vat photopolymerization, powder bed fusion, and sheet lamination is presented. The state‐of‐the‐art strategies implemented in manipulating anisotropic structures are highlighted with the discussion of material categories, functionalities, and potential applications. This review is concluded with analyzing the current challenges and providing perspectives for further development in this field.

“…Other significant studies have been conducted at Columbia University, at the Creative Machines Lab. They have 3D printed composite materials with the purpose of creating soft actuators (Miriyev et al 2019) with custom shapes, however in a small scale (the build plate is 406 × 406 × 76 mm). Moreover, the system doesn't allow for growing in height with the print, because of the liquid nature of silicone, despite UV curing.…”

This work introduces multi-material liquid printing as an enabling technology for designing programmed shape-shifting silicones. The goal of this research is to provide a readily available, scalable and customized approach at producing responsive 4D printed structures for a wide range of applications. Hence, the methodology allows customization at each step of the procedure by intervening either on the material composition and/or on the design and fabrication strategies for the production of responsive components. A significant endeavour is initiated to develop and engineer two different material systems that enable shape-shifting: silicone-ethanol composites and polyvinyl siloxane swelling rubbers. The printed samples successfully comply with the expected swelling behaviour through a variety of printed test patterns.
