The use of proprietary solutions by the ATMAT Saturn guarantees high quality and stability fo work, while safety systems allow it to meet the requirements of production lines. The machine is used in the industrial, architectural, automotive, and aviation sectors.
A heated working platform is a requirement for printing large-scale components. The working platform is equipped with a high efficient heating system, thanks to which the user can be sure that the whole work bed will be heated to the set temperature.
Granite is the material used as a work bed, has very good adhesive properties and does not deform during printing even the largest models.
The printer is equipped with two heads specifically designed for large-scale production.
The first is a high-performance head that uses two extruders with a connected mixing tank. This enables high speed printing with up to 0.5kg of material being processed per hour.
The second head is an auxiliary with a single extruder, used to produce support structures or models requires high levels of accuracy.
While designing a large-format 3D printer, it was important to assure the uninterrupted operation, which is the basic principle for long large-format prints. A filament case was created, which can hold 3 spools of filament, each up to 10 kg in weight.
This solution guarantees long-term printing and continuous work without the need to replace materials.
Additionally, the filaments are located in containers with dehumidifiers to limit the absorption of moisture from the air, which guarantees stability of their properties.
The head movement in the X and Y axes is performed by a magnetic linear drive with an absolute encoder. This drive guarantees higher speeds, acceleration and more accurate positioning. It has no mechanical parts that can be damaged.
The encoder allows continuous reading of the position in which the head is located, so there is no material displacement in the printer and each subsequent layer is always applied in the right place.
The printer is equipped with intelligent control systems that allow the user to react quickly to problems that may arise. In case of power failure, the user can resume the printing process, which in case of prints lasting several days guarantees stability and uninterrupted production.
The device is also equipped with a sensor of lack of filament flow, preventing sudden interruption of the printout, as well as a sensor for measuring the weight of the filament, allowing to predict the quantity of material needed to print the prepared model.
Besides, the device is equipped with automatic nozzle height calibration, semi-automatic bedlevelling, semi-automatic filament exchange and automatic levelling of the XY frame.
Maintaining a stable environment inside the printer's working chamber is a key function that impacts on the material used for printing.
Thanks to the constant temperature in the printed model there is no processing shrinkage, causing delamination of the layers and adhesion of the model to the bed is improved.
The design meets all strict health and safety requirements. Compliance with OHS principles is ensured by blocking access to the printing chamber during the production process, light-signalling informing about the stages of the printer's work, specialized marking of dangerous elements and appropriate buttons enabling the immediate stop of the current operation.
These printer properties make it a professional industrial machine, adapted to be operated in production plants.
