Thesis: Stereolithography is highly versatile compared to its competitors in the additive manufacturing market due to the combination of wide material range, accuracy, isotropic properties and geometrical complexity.

The article “A Review of Stereolithography: Processes and Systems”, written by Huang et al. (2020), provides a comprehensive review of the generations of stereolithography (SLA), its representative system configurations and derivative technologies. Stereolithography, one of the three most widely used approaches to additive manufacturing, utilises ultraviolet light to cure liquid resin layers (aka Vat Photopolymerisation or Photo-Solidification), thereby forming 3D objects with high precision and details.

This method has evolved through four significant phases, with increasing advantages over its competitors that thereby helps secure its spot in the 3D printing world. These mainly consist of high precision and resolution (layer thicknesses as fine as 25 microns and feature print sizes as small as 85 microns (Formlabs, n.d.), smooth surface finish [3], material versatility [4], complex geometries [5], and isotropic properties [6]; all of which will be discussed further with its shortcomings, together with its place in the additive manufacturing industry.

A Self-Introduction Email to Professor Brad

Subject: An introduction for the trimester Dear Prof. Brad Franklin Blackstone, I am Er Zhi Xian, a student of yours and also a freshman currently studying mechanical engineering in the Singapore Institute of Technology. I am reaching out to provide a more substantial introduction of myself to you. Formerly studying aeronautical engineering in SP, my initial fascination of aircrafts has morphed into a broader interest in consumer products and industrial machinery development. This change was largely influenced by my final year project, which served as a catalyst in shaping my current interest and workstyle. Believing that with more information comes better understanding when communicating, expressing my thoughts without fearing the extent of criticism has always been my strong suit. In groups, I would rarely hesitate in providing constructive feedback and would always encourage my teammates to reciprocate. For instance, during the aforementioned final year project, we were tasked in pr...

Interpretation of quote:

 “Communication skills are an essential component in the education of engineering students to facilitate not just students’ education but also to prepare them for their future careers.” Having read the quote, here is my interpretation: Certain knowledge and experiences learnt from the classroom does not necessarily translate to its use case outside. However, it highlights the fact that communication skills honed from the classroom is not just something that is useful as a self-development tool for students within a controlled academic setting, but also valuable beyond the boundaries of academia. Therefore, it seeks to enhance the importance of sharpening communication. This is ever-present having briefly entered the engineering industry, where issues arise from inadequate communication such as poor choice of words, leading to avoidable misunderstandings.
