| Abstract [eng] |
The main aim of this project is “Print Quality Improvement by Modernization of 3D Printer “Ultimaker 2+” Printhead”. We have many 3D printers with good and low surface quality, if the surface quality is low or medium we will not get the better result in final, so to overcome this disadvantage with the low cost we can develop a good printer head for the better quality of the surface. In this project, we analyze the printer head design for the better quality of the 3D prints because its application is numerous in social, geopolitical, industries and in all the places where we use the 3D models. First, we analyze many technologies which are present now and also consider what are the disadvantages with the present technologies mainly in technical specifications. By considering all the past decade results we decide what are changes to be made and we start implementing. We have consumer 3D printer which is varied on the production qualities of prints due to various factors such as layer thickness, line spacing, nozzle temperature, among others. Until today, a very light interest is given to the 3D print filament quality, and research about how the filament quality could affect the print quality. Here I consider mainly the nozzle temperature we can see many examples the prints which are printed in the low-temperature results the low-quality prints. We can see on the internet that Fused Filament Fabrication technology is the major technology which is used in 3D printing to print the parts. Here my idea is to design the 3D printer Ultimaker 2+ head and insert the piezoceramic (PZT 5A) at the nozzle and to calculate the frequency of the assembly, the frequency will be increased. Here I choose 0.4mm nozzle and also the with the help of increased frequency we use ultrasonic plastic welding to make layer strong, then calculate the temperature at the contact point of nozzle and plastic plate, the temperature must increase than the standard value because we are increasing the frequency. Here the prints are printed layer by layer of the size 0.06mm and we use ultrasonic plastic welding to connect the two layers to make the part stronger, with all these specifications the designed part is printed to check the surface quality. |
