Modular drying unit Storm

Humidity is the water that impregnates a body or the vapor present in the atmosphere. In the case of 3D printing, excessive moisture concentration in the filaments can cause a long list of problems that culminate in a failed 3D print.

Some of the most common setbacks are: increased brittleness, increased diameter (possible problems with printers that have a Bowden-type extrusion system), degradation (even reaching the breakage of the filament), etc. It is important to know that the filament should not be left in the printer if it is not going to be used, since it can get stuck in the extruder as it increases in diameter due to water absorption. It is also necessary to take into account the fact that the filaments affected by humidity will have a higher temperature for extrusion.

Humidity Issues

As a reason for the evolution of the world of 3D printing, there are filaments with great resistance to humidity, such as PETG or the CPE HG100, copolyesters that can be exposed to water for long periods of time without problems. Among the rest of the filaments we find some with moderate resistance, such as PLA or the ABS, and others, especially the nylons and the PVA, highly prone to moisture absorption, reaching high values ​​in less than a day.

Taking into account the importance of this problem, 3ntr; Italian company known for its industrial-grade 3D printers, has launched the STORM modular drying unit. Perfect match for 3D printers A2 and A4 from 3ntr, STORM brings together in one package all the necessary functions for uninterrupted, remotely accessible and secure service.

The STORM modular unit reaches a maximum temperature of 115 ºC, so it can be used with any polymer, it is also capable of reaching a peak power of 2250 W with an average power of 1250 W at 115 ºC.

Great capabilities

STORM contains space for up to 3 VENTO units (responsible for drying and maintaining any type of polymer in an optimal state to guarantee the best print quality), a high-performance print server with webcam for remote control of the printer and an uninterruptible power supply to avoid voltage spikes and guarantee the operation of the machine even in the event of a power outage.

Thanks to the VENTO units, STORM allows you to keep the filaments away from dust, humidity and UV rays. In addition, the STORM intelligent control electronics allows you to keep the polymers in the best conditions without the risk of degrading them with excessive heat. VENTO units use the least amount of electricity possible to keep the polymers in the best conditions for use without any risk.

STORM can integrate a print server, connected to the network, to remotely control the 3D printer through a computer or phone. In addition, through the webcam integrated by said server, it is also possible to monitor the progress of work live. This results in great time savings, especially if there are many units to keep under control.

Security systems

Professional 3D printing cannot tolerate power outages, so STORM includes a 3 Kw UPS to keep the printer running during power outages and keep all connections active. The UPS also minimizes damage from noise and power surges that can damage electronic components.

STORM has a dedicated compartment to house an F1 filter unit: a HEPA / VOC filter that prevents the environmental dispersion of microdust and volatile compounds. 3ntr 3D printers are closed boxes that minimize environmental dispersion, but the installation of an F1 system allows the user to achieve the best levels of security.

The STORM units are equipped with 3 easy-to-read LDC panels and with intuitive controls that allow monitoring the status of the VENTO units and the UPS.

Designed to contain up to 3 VENTO units and an F1 HEPA/VOC filtering unit for a safer printing environment, the STORM modular drying units complete the 3D printing experience of 3ntr protecting the polymers from humidity, UV rays and dust.

In very humid environments, certain filaments can absorb moisture and present problems during the printing process resulting in errors or poor quality prints. Among the most hygroscopic materials, we can find PA (Nylon) and TPU. The VENTO drying unit, stored inside STORM, allows the filament to be dried and kept in an optimal state to guarantee the best print quality. It is also compatible with any polymer.

In the world of industrial 3D printing, the use of technical materials such as ABS, nylon, ASA, etc. is common. At the time of processing, these filaments emit micro and nanoparticles into the environment so continued breathing of these elements can cause serious damage. The use of a filter significantly reduces this occurrence, so its use is recommended. The F1 filter unit, which can be housed in the STORM modular drying unit, is equipped with an industrial HEPA filter and an activated carbon filter. Designed to minimize the emission of both nanoparticles (greater than 0.5 microns) and volatile organic compounds, F1 makes the work environment a healthier place.
