The objective of this paper is to present the development of 3D digital manufacturing through synchronous 5-axes printing for greatly enhancing the strength of the printed parts. In traditional fused deposition manufacturing (FDM), which is one of the digital manufacturing technologies, the melted material is required to be extruded from the nozzle on the workspace platform with a fixed direction. The strength is restricted in the direction of perpendicular to the layers since the printing way is layer by layer. The poor adhesion between the layers becomes a weakness to resist external force, especially when the force exerted from different directions. In this paper, algorithms for synchronous five axes printing based on the surface printing trajectory has been proposed to overcome the lack of strength issue. A five axes synchronous 3D printing machine developed in our NTU Intelligent Robotics and Automation Lab enhances the strength of the printed parts by adding additional materials to the surface of the parts. Five axes printing can achieve the goal of printing in different orientations so that the strength of the printed parts is greatly enhanced in comparison with the printing in a fixed direction only. The five axes synchronous 3D printing has been successfully demonstrated in physical printing. The strength analysis of printed parts is also performed under the three-point bending test and the tensile test. It shows that the strength of the five axes printed sample is increased by nearly three times in the bending test and nearly two times stronger in the tensile test.

“…One of the main challenges within the field of 3D printing is the cost of time consumption needed to create objects. [11] describes a proposed method of using a "novel additive process optimization algorithm for reducing the consumption time in 3D printing process". Such a topic may be out of the scope of the current stage of design and prototyping, but it is likely time consumption will need to be taken into account if multiple models need to be printed at the same time in the future.…”

Online laboratories help students to perform laboratory assignments from different geographical locations, through the use of internet. A possible configuration is the hybrid laboratories, that includes the use of a physical local experiment equipment, and a set of either virtual or remote laboratory components. One of the issues of this type of setups is how to determine whether the student is really performing the lab activities or she/he is presenting somebody else work. Therefore, it is important to take all the necessary steps to keep the students engaged while preventing academic dishonesty. This paper proposed a prototype of an Anti-Cheating student lab kit case, which can help to prevent plagiarism and cheating in the engineering laboratories. This case includes several measures to avoid dishonesty in engineering courses, such as software and hardware solutions. This paper will go into more detail of how the student lab kit case was designed and what challenges were faced during its implemenation.
