Risks when printing in 3D

Every day 3D printing is more widespread both at the industrial level and at the domestic level, something that enhances the development of many applications in a large number of fields. At the media level only the benefits of technology stand out, but there are certain precautions that must be taken into account when it comes to starting in the world of 3D printing.

But every user must take into account certain risks that may occur during 3D printing. The two main sources of risk and more common are on the one hand the gases released during the fusion of the material, and on the other the possible sources of fire by misuse of the 3D printer or the poor condition of the electronics of the same.


It must be taken into account that the characteristics of the electrical network to which the 3D printer is connected must be exactly those indicated on the machine: 230 Vac, 50Hz. In addition, attention should be paid to where the 3D printer connects. If it’s fed from a terminal strip with more consumers, it can cause fuses to blow or the protections of the installation to skip. Therefore, the characteristics of the line must be checked before the connection. When cleaning the 3D printer, always disconnect the 3D printer from the electrical outlets to avoid accidental contacts.


The use of quality electronic components, as well as cables with the appropriate section is crucial to avoid excess temperatures that can lead to the fire of the 3D printer itself and this, in turn, of everything that is around it. Another possible problem that can also cause a fire is that the temperature sensor comes out of its housing and the heating cartridge raises its temperature to the maximum, melting the elements that are around it and can cause fire.
