There are some situations that reoccur and lead to frustration. Here is the list of the seven 3D printing experiences that has gone worst:

• Discovery the 16 hour whole night print stopped in mid-print and caused a lengthy reprint and some wasted filament.

• Discovering the 16 hour overnight print slipped off the print surface and caused a massive plastic mess in your 3D printer. And a reprint also.

• Discovering the 16 hour overnight print slipped off the print surface, causing a massive plastic mess that attached to your extruder and broke or burned your extruder.

• A large print failed after only one 0.1mm layer and caused you to spent considerable time picking off the microscopic plastic debris off the print plate.

• A tiny contaminant in the plastic filament found its way to the tip of your hot end and caused an irremovable blockage, either permanently wrecking your extruder or requiring you to burn it out.

• Waiting for weeks for the spare parts to arrive from to fix your otherwise inoperable 3D printer.

• First waiting weeks for spare parts to arrive from and then to fix your otherwise inoperable 3D printer and suddenly discovering you owe a big amount in customs duties to receive them at your door step.
