Specific techniques for printing 3D objects

Techniques for implementing 3D objects are synthetized, emphasizing the most useful ones that could save time and expensive materials for creating scientific or home objects, for research or for nowadays use. We present how to project and how to process them, using different types of texture with shapes adapted to our needs. A comparative study of printing 3D objects with two different types of devices is proposed: (i) DaVinci printer device that uses high detail texture, cold printing bed, and extruder with PLA filament at the temperature of 203°C, 90% infill density, and (ii) Prusa printer device with heated bed, 70% infill density, and extruder with PLA type filament at the temperature of 215°C. Following this study, an optimal approach to the design and printing of 3D objects is outlined. Moreover, our study can be used as a didactic material helping students to improve their knowledge and abilities in the field.
