The final object is here:
From the video a few issues with printing can be seen which I hope to work on improving in the future:
- Speed. The printer is not very fast. Increasing the speed is certainly possible, but I need to make sure I have enough spare parts to repair the printer if I break it before I attempt to do that.
- PLA dripping out after the extruder motor stops. It can be observed that after the test extrusion, when I have removed the extruded plastic hanging from the nozzle, that melted PLA drips out. This results in blobs on printed objects which should not be necessary.
- The first few centimeters of printing did not work. This could be related to the previous issue: plastic has been dripping out and pressure has to be build up before there is a constant flow of plastic.
This object can be found at thingiverse here and is my favorite test object which has been printed quite a few times in different materials and different sizes.
