ABOUT PRiSME2018 The 3rd Postgraduate Research Symposium on Mechanical Engineering (PRiSME2018) is jointly organized by the Faculty of Mechanical Engineering (FKM) and the Centre for Advanced Research on Energy (CARe), Universiti Teknikal Malaysia Melaka (UTeM). This symposium is officially hosted by the FKM Postgraduate Committee. The event will take place at Kampus Teknologi UTeM on 17 January 2018. PRiSME provides an opportunity for graduate students to explore and share their research interests, under the guidance of a panel of distinguished experts in the field. The symposium has three primary objectives:

1. To provide a platform for postgraduate students to share their research progress in a friendly environment.

2. To provide opportunities for postgraduate students and participants to receive informal in-depth feedback through discussions, and to enable them to establish contact with other postgraduate students.

3. To help students strategize about their research and dissertation, as well as publication of their research in peer-reviewed journals.

In accordance with our regulations for Annual Review of Postgraduate Research Students, attendance and presentation at the symposium is compulsory for all registered and full-time research students (semester 3 and above). Attendance is not compulsory for full-time research students in Semester 1-2, part-time research students, or students in their waiting for graduation (completed the viva-voce). This year, 52 postgraduate students of FKM will make a presentation in this symposium. The presentation materials does not need to be a finished piece of work. The intention is that this exercise should be useful for postgraduate students, both in terms of clarifying their own ideas and gaining more experience of presenting them, and in allowing them to benefit from the questions and comments of those in attendance.

MESSAGE FROM DEAN Assalamu’alaikum wrt. wbt, and Salam 1Malaysia, I would like to express warmest welcome to all participants to the 3rd Postgraduate Research Symposium on Mechanical Engineering

(PRiSME2018), which is jointly organized by the Faculty of Mechanical Engineering (FKM) and Centre for Advanced Research on Energy (CARe), UTeM. This symposium is officially hosted by the FKM Postgraduate Committee. The faculty has been successfully organizing the Postgraduate research seminar since 2011. Starting from 2015, the seminar incorporates symposium format. With the current change, it is hoped that the symposium will serve as an effective platform for research students to present their progress while ensuring valuable constructive feedback from the expert members in each research group. Organizing a symposium is important as it promotes conducive research atmosphere in the faculty and also ensures many significant research findings generated from respective research projects. Our sincere thanks to all supervisors, postgraduate student members, lecturers and our support staff who contribute their efforts to make this symposium a beneficial experience for everyone. I would also like to congratulate the PRiSME2018 organizing committees for making this symposium a success. I am sure with the previous experience; the committee will certainly implement substantial improvements and innovations to make this event more productive and interesting. Finally, I hope the input received from PRiSME2018 will encouragingly increase the quality and timeliness of the students’ research, leading to a successful viva and outstanding publications. Thank you.

Keywords: 3D printing; Plant based adhesive; Formaldehyde emission

ABSTRACT Purpose – To investigate layer adhesion of 3D Printer by applying plant-based bio-adhesive on the printing bed to enhance manufacturability Design/methodology/approach – Bio-adhesive material was prepared from four plant-based; cassava, soy and rice, sago. The mechanical testing as performed for the layer adhesion between 3D printer glass and printed part. Manufacturability and quality inspection was conducted incorporated model with complex geometry. Suitable adhesion material was selected using a deisgn approach. Findings – The results show that the tensile strength for bio-adhesive sample has lower value of 0.495MPa as compared to the synthetic adhesive samples of 1.289MPa. In addition, Bio-adhesive samples has higher percentage warping deformation with 2.25% in comparison to the synthetic adhesive of 0.88%. Originality/value – A major problem is the printed part tends to shrink and warp. It can be reduced by applying synthetic adhesive onto the platform. However, there is a limited study regarding the use of bio-adhesion to overcome this problem.

MECHANICAL BEHAVIOR OF PARTS FABRICATED VIA OPEN

SOURCE 3D PRINTER

Siti Najatul Aishah*, Mohd Rizal Alkahari, Faiz Redza Ramli



Keywords: Additive manufacturing; Fused deposition modeling; Pressing

ABSTRACT Purpose – To enhance the mechanical properties of the printed part by improving the open source 3D printer with mechanical pressing. Design/methodology/approach – The samples have been printed using ABS material conforming to the ASTM D638 standard and printed using low-range 3D printer, mid-range 3D printer and improved 3D printer. The mechanical properties of the samples was investigated by testing the surface roughness, tensile strength, and porosity percentage. Findings – The results showed that tensile strength of the samples printed using 3D printer integrated with pressure produced a greater value and significantly reduced the porosity percentage and roughness compared to the mid-range and low-range 3D printer due to the larger contact surface area between the layers during the pressing process. Originality/value – The results of the experimental studies demostrate the potential of the mechanical pressing to be adapted in the 3D printing process for reducing the porosity percentage between the layers and concurrently enhance the strengh o the printed part.

METAL PART

Ng Chin Tatt*, Mohd Rizal Alkahari, Faiz Redza Ramli



Keywords: Selective laser melting (SLM), 3D metal printing, surface integrity

ABSTRACT Purpose – To analyse the surface integrity and characterisation of 3D metal part printed from 3D metal printer. Design/methodology/approach – Porosity, surface roughness is observed and recorded using different samples. Different geometry of printed parts will be used as observing samples. The samples are observed again after sandblast to determine the improvement in surface integrity. Apart from printed parts, the build platform is also used as samples in this process. Findings – The porosity of the 3D printed metal part using Stainless Steel 316L powder bonds each other well with 50 microns in average size and shows little gap between particles. The surface roughness of metal part exceeds the expected roughness and is better after undergoes sandblast. Originality/value – The 3D metal printer that is used is considered a low-cost machine that uses SLM process to fuse the metal powder. The surface integrity of the 3D metal printed part has yet to be recorded by anyone using similar machine.
