Chapter 1: 3D Printing
3D printing transforms three-dimensional models into physical objects that you can
touch and hold in your hand. This printing process is also known as additive
manufacturing, because the 3D model is created by applying layers until the object is
fully formed.
Fused Filament Fabrication (FFF) is the most common method of 3D printing and is
also used by this 3D printer. In this printing method, a plastic, the filament, is melted
at high temperature and applied to a printing surface. The filament solidifies during
cooling, i.e. practically immediately after it leaves the nozzle. 3D objects are formed
by applying the filament in several layers on top of each other.

1.1 Procedure

3D printing involves three steps:
1.) Create or download a 3D model
2.) Slicing and exporting the 3D model
3.) Building the 3D model

1.1.1 Creation of a 3D model:

Currently there are three ways to create a 3D model:
- Design from scratch You can use free CAD (Computer-Aided Design) software
such as 3DTADA, AutoCAD, SolidWorks, Pro-E or our own software Happy 3D to
design your own 3D model.
- 3D scanner As an alternative to creating a 3D model, you can also scan an object.
A 3D scanner digitises a physical object by capturing the geometric data of the
object and saving it in a file on the computer. It is also possible to use a mobile
device as a 3D scanner using an app.
- From the cloud The most common method of obtaining a 3D model at present is to
download a 3D model from a website where users can upload their own 3D
models.

1.1.2 Slicing and exporting a 3D model:

Slicer software is used to prepare 3D models for printing and convert them into
instructions for the 3D printer. REXprint is the slicer software for this 3D printer. With
REXprint, STL files can be converted into G or GX files for printing. These are then
transferred to the 3D printer via USB cable, USB stick or W-LAN.
