Ghosting: (cube 1 and 2)
The term referring to the subtle disruptions in the printing lines are clearly shown in cube 1 and 2. The ghosting effect is caused due to vibration of the motors, causing the extruder to subtly wobble while printing. This issue can be resolved by using foam pads on the bottom of the printer's feet to absorb shaking.
Stepper motor calibration: (cube 2,3,4)
This was an issue which would resolve over or under extrusion issues in the prints. In the imperfect prints at the top, bulges around the print can be observed. These bulges can be the result of over extrusion, when the extruder pushes more filament out than it should.
Acceleration and Jerk:(5)
In a custom/ commercial printer, the acceleration and jerk settings can be changed so that the print speeds can be increased. However, with these settings increased, it can result in a poor quality print found in the black cube. Reducing the acceleration in a Cartesian printer to around 500 and the jerk to around 10 for the x,y, and z axis produced better results. In addition, increase the retraction acceleration seemed to have benefited the prints.
Nozzle Replacement: (cube 6)
The printer used to print the black cube has have over a year of printing, thus leading to a degrading of the nozzle and the quality of the nozzle diameter. This degradation can lead to inconsistent printing pressures and thicker print lines. In the last print, a new 0.4mm nozzle is used, and it obviously shows a greater improvement. *A different file was used in cube 6 to demonstrate the finer detailed print of smaller spacer
