To make a LED impression in a trial is not complicated at all. It merely needs a good plan for the process and a little bit of preparation: the LEDs are joined up to each other, the cable soldered, a switching system is thought out and finally a 3D shape is designed to enclose it. | |||
The fabrication process caused some complications. The extruder failed several times because the material got jammed. If noticed on time, the model was not lost, it just showed some flaws; the edges were not refined by another layer. The model was printed with using PLA. Due to the transparency it is a little bit harder to notice if the extruder is still working or not. | |||
For better transparency and faster printing a thin-walled 3D model should be designed, as the translucence is better and also the printing time is considerably shorter. | |||
*1. Trial | |||
**1. The printing process starts with default settings from the program for PLA (with only 180°C printing temperature). | |||
**2. After 45 minutes the plinth base was printed | |||
**3. After 3 hours and 45 minutes congestion of the material. Because of some reason the drive shaft spins, after a while the same problem occurred. | |||
**4. The data cable got partly loose. The carriage is still working but the screw from the material transportation was standing still. | |||
Abort of the printing process | |||

*2. Trial | |||
**1. New trial with a new model | |||
**2. Presetting for PLA printing temperature: 205°C | |||
**3. Congestion of the material still happens with higher temperature. It is reduced by tightening the screws. | |||
**4. If the fan goes on and off often, this might have to do with the temperature setting, which is exactly on the limit of the cooling and not cooling. | |||
