Problem

Our customer asked us to design and implement a complete 3D impression system for printing homes.
Some of the requirements were that it has to be a fully automated system and implement machine safety.

Solution

The PC&E team designed a large 3D printing system consisting of a robot with an extruder to melt PET G pellets, a safety barrier with a safety light curtain to provide protection for those in the work area.

Which includes a main control cabinet that contains the PLC, CB and other control components; as well as an auxiliary control cabinet with HMI and Emergency Stop for supervision.

The control system for the extruder machine uses a SIMATIC S7 1200 PLC with I/O modules to control the temperature. And the HMI allows the operator to monitor and control parameters of the machine.
