Introduction
Thank you very much for choosing this book!
As an engineer and 3D printing enthusiast, I am familiar with all the pitfalls of 3D printing in detail. 3D printing is a process that needs to be mastered. The 3D Printer may initially (and this is what most people - including me - have experienced at the beginning) produce a variety of unsatisfactory results.
This can literally drive you crazy and make you want to give up on this ingenious technology. Especially if the poor printing results are not limited to the beginning of your printing, but occur again and again, with no solution at hand.
This is over now! For all those who are looking for a handbook of all 3D printing failures, this compact manual was written. In the following chapters, you will find a description of each issue pattern followed by a section about the possible causes and specific steps to solve the problem. Numerous images help you with troubleshooting your way through 3D Printing.
This book is designed for both beginners and intermediates.
With this handbook, you can gain a solid understanding of solving 3D printing trouble and learn everything you need to know to:
a) avoid 3D printing errors from the very beginning,
b) classify 3D printing failures that have already occurred,
c) understand the underlying causes, and,
d) take an appropriate troubleshooting approach
That being said, let's get started

1 Basics: Tips & Tricks for High-Quality Printing Results
Before you start a 3D printing job, you should ensure that the following basics have been considered sufficiently:
a) The print bed is leveled:
Print bed leveling is one of the most important procedures in FDM 3D printing. If the distance between the nozzle and the print bed is not correct (too large / too small), the object will not adhere. In chapter 4, you will find a leveling guide that explains the leveling process in detail.
b) Bolts are tightened / belts are tensioned:
Check all bolts of the 3D Printer for sufficient tightness and whether all drive belts are sufficiently tensioned because mechanical discrepancies can also lead to printing errors.
c) Solid installation site:
The 3D Printer should be placed on a solid and vibration-dampening platform, such as a solid workbench or aluminum frame. Otherwise, vibrations may build up and be transmitted to the print head, and thus affecting the print result negatively.
d) Environment:
Operate the 3D Printer in a room with a constant temperature in the range of 20 - 23° C (65 - 75° F) and a low humidity level (up to about 40 %). Opened filament has to be stored in a closed box with moisture-absorbing material (e.g., silica gel). The room should also be as clean as possible. Avoid any excessive amounts of dust, oil, or other substances (garage (oil), laundry room (humidity): rather unsuitable).
e) Printing Temperature:
Choose a print bed & nozzle temperature that is suitable for your filament. This is usually specified by the filament manufacturer itself and can be found on the packaging. Print a "Temperature Tower" (thingiverse.com) in order to find the optimal printing temperature.
f) Print speed:
Print at a slow (overall) speed (e.g.: 60 - 100 mm/s). This will give you a high print quality.
Safety Instructions for 3D Printing:
Figure 1: Safety Instructions
The printing nozzle must heat up to approx. 200° C (400° F) to melt the filament. The print bed also heats up to approx. 60° C (140° F). Therefore, there is a high risk of burns, especially at the nozzle. Do not touch moving parts either; while the printer is running, there is a danger of crushing. Find a suitable place to set up the 3D Printer, ideally in a somewhat closed room, as the printer does generate noise and vapors (hazardous to health, e.g., with ABS). Also, make sure that children and pets do not have access to the 3D Printer. It is also a good idea to spend a few minutes at the start of each print job to check whether everything is being carried out correctly. In addition, you could install a camera for remote monitoring.
In the next chapter, you will find an image-based directory containing chapter references for easy identification of printing failures (compare/search for your pattern and look up the chapter reference), before we deal with the specific error patterns in detail. In addition, a chapter on critical components of an FDM 3D Printer and a leveling guide is waiting for you!
