Project: Teacher4.0 - comprehensive method of implementation of Industry 4.0
concept into didactic practice in primary and secondary schools

Performing the first layer completely lowers the model along the Z axis or raises the head along the Z
axis. Thanks to this, by applying layer by layer, a three-dimensional model is created. After printing is
finished, we remove our solid from the heatbed.

What materials are used in the FDM method?

The big advantage of FDM / FFF printing is the possibility of using a wide range of filaments
depending on what we need to get and what our budget is. It is the materials that largely determine
the properties of the printed model. One of the most popular materials used in the 3D printing
method is ABS and PLA (material based on organic compounds). Equally popular are nylon used for
the production of ropes, PETG used in the production of plastic bottles or TPU which is a material
resembling rubber.

Due to the fact that the materials of the same type are used in mass production on industrial
injection molding machines, FDM printing has the ability to obtain similar physical and chemical
properties to the final product. However, its advantage is the ability to create individual pieces,
which in the case of injection molding machines is unprofitable.
Filaments available on the market are offered in different colors, so it depends on our choice and the
printer's capabilities (one or two heads or making a pause while printing and replacing the filament),
how many colors and what our model will be built

Below is a brief description of the most popular materials used in FDM printing technology:

Material Properities

ABS - good strength properties
- good thermal resistance
- deformability
Nylon (PA) - very good strength properties
- high resistance to abrasive wear and chemicals
- low resistance to moisture
PC - high accuracy
- very good strength properties
- rigid and abrasion-resistant components after printing
ABS-ESD7 - dissipates charges (antistatic)
- ideal for electronics housings

ULTEM - very good strength properties
- fire resistance and resistance to chemicals
- High price
