About the Author
Introduction
When I first started working with 3D printers, I was overwhelmed by the
amount of knowledge required to have consecutive successful prints. Since I
was aware of the acceptable failure rate for most other manufacturing
machines, I was blown away by just how inconsistent 3D printing can be
without frequent, proper maintenance.
Many desktop 3D printing companies advertise a plug and play machine that
can be operated consistently without any engineering background, which is
generally not true. 3D printing has been marketed by many as a magical
solution to manufacturing and prototyping, but anyone who has used these
machines will be able to tell you different.
From the time I began in this industry over two years ago, up to the point of
writing this book, I have amassed over 50,000 hours of successful printing
experience across over two dozen machines. I have repaired just about every
section of the printer and have even built my own. Since prints can fail up to
20% of the time, you can be safe to assume I have had to fix just about every
issue you will come across.
In the diagnostic section in the beginning of this book I will go over some of
the visual symptoms that you may see when your printer is malfunctioning,
and what could be causing the problem. Whatever failure or ugly print you
are experiencing, you should be able to compare it to the problem described,
and then go to the designated chapters in order to fix.
My goal with this book is to take every failure I have witnessed and put it
into one resource. This book should be able to help you fix close to 100% of
the problems you are going to experience with your 3D printer. If you
purchased this book and it does not help you with your specific problem, I
offer you to contact me anytime at my YouTube channel
The 3D Print
General (www.YouTube.com/The3DPrintGeneral),
or to email me at
Sean@3DPrintGeneral.com There are further tutorials, fun prints, and even
giveaways frequently posted to the YouTube channel.
I also started a website - 3DPrintGeneral.com - where I link to products that I
use and trust.
