Hello there friends,
I recently bought an Ultimaker 3D printer after a lot of search on google.
I knew from the very beginning that 3D printing is something that needs a loooooot of time to master (if it can be mastered).
I am currently working as an industrial Designer in Athens Greece and i have some complex models in my library to print.
I started printing some models and i am having a hard time understanding all the parameters of the CURA menu.
First of all, the parameters i used for printing these models are 55mm/s printing speed, 202oC nozzle temp, 35mm/s first layer printing speed, 40mm/s travel speed and 0.1mm layer height.
As you can see, i get a smooth continuity but in some points the model seems to spit some plastic. Like when the extruder changes direction, it gathers a lot of melted material in one place and it falls from the sides.
It looks like plastic bubbles on some corners.
On another model (toothbrush holder), the same thing happens in a smooth surface.
In addition to that, in this model, the surface finish seems to deteriorate a lot at the narrow points where the nozzle does very quick moves.
Printing parameters are same to both of them.
I tried raising temp to 220 and speed to 80 when printing and it became worse i think (i did not let it continue with that parameters).
Could anyone please give me some general advice about printing parameters?
In addition to that, if you could advice me specifically for these examples, i would be grateful.
Thank you in advance and Merry Christmas to all of you!
