Filtering capabilities of the S5 pro bundle

Recommended Posts

Posted · Filtering capabilities of the S5 pro bundle

I'm interested in buying an S5 pro bundle for printing with ABS indoors without too much room ventilation. I'm concerned about volatile organic compounds (VOC), in addition to ultra fine particles (UFP). I have read that the S5 pro bundle includes a filter that removes up to 95% of UFPs. However, based on my understanding, VOCs are also emitted when printing with ABS. Is the filter system for the S5 pro bundle able to remove VOCs from air?

Ultimaker has a fact sheet out on the Air Manager (can't find the link for it right now), but as I recall, they show the VOC level, even when printing ABS, is extremely low, and well below the limits established by regulators.  I think that is why they decided not to add an activated charcoal filter to the Air Manager.

Unfortunately, micro-plastics, which are emitted during printing, are so small that they pass right through even a HEPA filter.  This is of concern as its not clear what the long term affects are of this on humans. Best practices would have you print in a separate room or to introduce ventilation.  We recently put a full enclosure on our Ultimaker 3 and ducted a very low cfm fan to blow the air outside during printing. Kind of like a dust collection system that you might see in a wood shop.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
