3D Troubleshooting

The 3D printer is an important aspect of rapid prototyping. To maintain the quality of the object & the long life of the machine we need to take some precautions while printing and provide regular maintenance to the machine.

Bed Level – Every printer has a different mechanism to level. The word 'level' means the gap between the bed & nozzle at 5 Points. (4 Corner of bed & 1 centre). The minimum distance between the nozzle and the bed should not be more or less than 0.05 mm (thickness of A4 size paper).

Nozzle Cleaning – A significant problem faced by many 3D printers is that of nozzle clogging. Go through your 3D Printer Manual for the process of nozzle cleaning for your respective printer.

Here are some of the problems you may encounter during 3D printing and their major causes.

Not Extruding at start of print

Major Causes:

•Filament was not loaded into extruder before printing

•The distance between nozzle and bed is too close

•The filament stripped against the drive gear

•The extruder is clogged

Print not sticking to the bed

Major Causes:

•Build platform is not level

•Nozzle starts too far away from the bed

•First layer is printing too fast

•Temperature or cooling settings

•The build platform surface (tape, glues and materials)

•When all else fails: Brims and Rafts

Snoozing or oozing

Major Causes:

•Retraction distance

•Retraction speed

•Temperature is too high

Layer shifting or Misalignment

Major causes:

•Nozzle moves too fast

•Mechanical or Electrical issues

Grinding Filament

Solution:

•Increase the extruder temperature

•Change speed

•Check for a nozzle clog

•Level your bed

Clogged Extruder

Solution:

•Manually push the filament to extruder

•Reload the filament

•Clean out the nozzle

Assessment

The teachers must mandatorily answer the questions in order to complete the course. Kindly fill out all the form given below.

Did you know

The history of 3D printing goes back to the 1980s.

With the help of 3D Printing technology, people have already managed to create artificial organs.

There are 3D printers that use Gold, Silver, Titanium, wood etc. for 3D Modelling.
