  Description 3D Printer (ARCAM EBM SPECTRA H) 1. JiaJun and Royce came from similar backgrounds as both graduated from aerospace engineering courses and had final-year projects that allowed them to use similar machinery.  2. The team decided to focus on 3D printers specifically the (ARCAM EBM SPECTRA H) type printer. 3. Using multiple sources specifically the product brochure and the official website and found out about the product in more detail. 4. Using (chatgpt) gAI, information about the printer like usability, specifications and functions could be found. 5. Using both Google Search and (chatgpt) gAI information to cross-reference and check to ensure that there is no discrepancy between the 2 sources. 6. The team found the product specifications, functions and features using the above-mentioned websites.

The ARCAM EBM Spectra H is an advanced electron beam melting (EBM) 3D printing system developed by GE Additive, specifically designed for high-temperature materials such as titanium aluminides and Alloy 718 which are known to be crack-prone. (OpenAI 2024). The Spectra H is part of the ARCAM EBM series, which is known for its capability to produce parts with high density and mechanical properties that are comparable to wrought materials. The machine is the new top-of-the-line EBM printer that does additive manufacturing better than past models. Its size is 1328 x 2344 x 2858mm (D, W,H) and its build volume is 250 x 430mm (D, H). The typical process temperature range is 600 to 1100 degrees Celsius and the max beam power is at 6kW. It is commonly used in the aerospace, medical and automotive industries where complex high-strength metal parts with intricate and tight tolerances are essential. (Griffiths 2018). The machine can recover unused powder in a closed environment as when a part...

  Hello Professor Blackstone, I am Royce, currently a Year 1 student in Mechanical Design and Manufacturing Engineering (MDME) from Singapore Institute of Technology (SIT). Prior to this, I graduated from 5 years of tertiary education from niche engineering courses - Mechanical Engineering course at the Institute of Technical Education (ITE) and Aerospace Engineering course at Temasek Polytechnic (TP). Since I was a child, I have been fascinated in the mechanical operations aspect of aeroplanes. During my internship programme while studying in TP, I realised that I particularly enjoyed the design and manufacturing process especially Computer Aided Design (CAD) for short. I enjoy 3D modelling and completing intricate and detailed designs makes me happy which is what fueled my motivation to join this course. One of my strengths would be being a good listener. I have held leadership positions while I studied in both ITE and TP, working with various personalities. These experiences tau...

Quote 1 “I contend that we (engineers) are undervalued because of our widespread inability to explain what we do to the general public (and why it is so important). It is one of the hardest goals to accomplish, to be able to boil down difficult concepts into a short and easily understood presentation or elevator pitch.” Marybeth Miceli, President, Miceli Infrastructure Consulting, USA (2011) Personal Thoughts I think that this statement accurately describes the situation that engineers around the world face. Often time while we are able to understand the topic at a deeper level due to the background of knowledge that we have. Explaining it to investors or the general public might be harder as they might not have the same background of knowledge that an engineer has on the topic to be able to understand the concepts and technical details of certain inventions.   For example, if we (engineers) explain about how we applied the concept of "Statics and Dynamics" into our robot ...
