3D Printing Principle and Printer Assembly

Introduction

This course teaches you how to make a 3D printer for yourself and calibrate and adjust it perfectly. You will get to know how to solve and prevent common problems and discover alternative solutions to tailor your 3D printer to your liking and needs. You will learn how to assemble parts for your 3D printer and build it with ordinary tools and skills.
