heal.abstract |
3D Printing and Fused Filament fabrication is an upcoming technology and research field. During the few past years it has seen an incredible commercial and technological rise, more and more products are being launched each month and research publications are continually increased. One of the most important parameters in 3D Printing is the material used. There is a vast arsenal of thermoplastics in the market that satisfy the needs of the current market. However, there is an upcoming research interest in High Performance Thermoplastics, which are plastics with increased mechanical and thermal properties when compared to thermoplastics and find extended use in “engineering” and medical fields. The main subject of this work is the Development of a 3D printer for high performance thermoplastic materials and is focused on the explanation of design steps and decisions that had to be taken in order to reach the goal. An array of High performance plastics was compared and Ultem1010 was found to be the most suitable candidate. During the design process, various systems and subsystems of the Printer were modified, and some completely changed in order to meet the requirements of such demanding printing conditions. During the redesign process it was of outmost importance to point out why each decision was taken.
After the printer was rebuild and various electronic automations were incorporated, that were designed and manufactured for the purposes of this work, calibration procedures were initiated to give as good as possible prints before migrating to Ultem1010 printing. At the moment the printer was producing good quality parts from common thermoplastics and the printing parameters were identified to be appropriate the migration to Ultem1010 occurred. In the end, a detailed and documented series of trials is demonstrated, explaining each step of the procedure that was followed in order to reach the main goal. A series of printed Ultem1010 parts is exhibited and a discussion is made about the evaluation of the results, the future of the dedicated printer and High Performance Plastics in general. |
