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.

Antimicrobial Materials

Antimicrobial materials produced by 3D Printing technology are very beneficial, especially for biomedical applications. Antimicrobial surfaces specifically with enhanced antibacterial property have been prepared using several quaternary salt-based agents, such as quaternary ammonium salts and metallic nanoparticles (NPs), such as copper and zinc, which are incorporated into a polymeric matrix mainly through copolymerization grafting and ionic exchange. This review compared different materials for their effectiveness in providing antimicrobial properties on surfaces. This study will help researchers choose the most suitable method of developing antimicrobial surfaces with the highest efficiency, which can be applied to develop products compatible with 3D Printing Technology.

Variable Universe Fuzzy Control

Selective micro heat sintering (SMHS)-type 3D printing technology is a widely applied method in rapid prototyping, which uses an electric heating component to sinter non-metallic powder. It requires precise control of the heating component’s energy and its sintering time. Temperature is one of the key factors that affect the forming quality of fused-type 3D printing technology. Aiming at the nonlinear and time-delay characteristics of temperature control in fused-type 3D printing, a fuzzy control method based on variable universe fuzzy control was studied. This fuzzy control method adopts a set of nonlinear expansion-contraction factors to make the variable universes change with the adaptive error, which can help acquire adaptive temperature adjustment in the rapid prototyping process control. The results of the simulation and experiment showed that the controlled temperature response was faster, the overshoot was smaller, and the stability was better compared to the conventional fuzzy proportion integration differentiation (PID) algorithm after the temperature reached the target temperature. The printed results indicated that the universe fuzzy PID control can effectively improve the accuracy of the workpiece shapes and that the density distribution of the workpiece is increased, which can help improve the forming quality.

Construction Design

An increasing number of designs and subsequent production of parts created by the Rapid prototyping (RP) [1] technology led to a problem with the maximum workspace of the 3D printer. Due to this reason, it was necessary to work on the solution of joining the parts to overcome the limited workspace of the printer. This article is devoted to glue joints analysis of two parts made by RP technology. A great emphasis is given to the load capacity testing of the parts made this way. The measured values than may serve as a lead for the construction design of the outlined joints. The article builds on the knowledge gained during the previous testing of the screw connections of parts made by 3D printing technology [2].

Main Requirement

Industrial Revolution 4.0 requires every line of life to apply technology, especially in the field of prototyping. 3D PrintingFDM (Fused Deposition Modeling) technology is used for the needs of rapid prototyping. The plastic filament material is the main requirement in printing FDM or FFF (Fused Filament Fabrication). However, there are poor print quality problems in this storage process because all types of plastic filaments used in this 3D printing technology are affected by moisture and dust. The moisture of the plastic filament can be seen if there is a hiss in the printing process and the surface of the printing result becomes rough. At the same time, the dust on the filament will clog the hot end nozzle. Current 3D printing technology is used to reduce this problem by storing filaments in the filament box dryer. However, this storage has several drawbacks. It is less efficient and practical because the filament box can only hold one of the plastic filament rolls. From this problem, we tried to create "Direct Filament Dryer with Moisture and Dust Absorbent for 3D Printing Plastic Filaments". The principle of this tool is to put the filament into the heating chamber. This room contains silica gel as a damper for moisture and a sponge to clean the dust on the filament's surface. The heating room temperature is controlled by a thermostat, which will keep the temperature between 40-50 °C. This research uses R&D techniques with the 4D method, namely, Define, Design, Develop, and Disseminate. Meanwhile, to test the results of this research by comparing the printing results between plastic filaments that are allowed to become damp and dusty with technology. Therefore, it was concluded that using made the filament surface smooth without any rough parts.
