Are the toxic and smelly fumes from the resin extracted only through the vent grid located on the rear of the Slash, or also through the bottom grid underneath the printer?

Okay… my question was not about heat extraction, it was about fumes extraction. For the second time: How and where are resin fumes extracted?
The resin is quite smelly. When the printer is active, there is a strong odor in the room, even if it is ventilated. In winter in some countries it will not be possible to open the windows (too cold outside).
The second question is then: is there a mean to extract these fumes through a hose? That is why I want to know how currently those fumes get out of the printer and end up in the ambient air.
This even gives me headaches. Is there a high quality filter in the printer by the way?
You can place an air purifier in the room, or move it to your bathroom? To be honest, I have no good idea to extract the fumes, because it evaporates from the resin tank and the printing process.
My analysis, reading “between your lines” and observing the machine:
Everyone understand that fumes are actually evaporated resin, this is the definition of such fumes on a 3D printer. These fumes manage to get out of the printer from all possible non-airtight junctions, and in all probability mainly through the vent on the rear that was yet primarily designed to extract heat out of the machine (as fresh air goes in from the bottom vent). So the evaporated resin (fumes) are extracted with heat but no one at Uniz thought it would be a problem. Therefore the machine has not been designed to extract fumes through a particular area of the machine. Some of your competitors build SLA/DLP 3D printers that extract fumes through a dedicated vent grid located on the rear which also contains a high-quality filter, because they simply care about the health of their customers and their relatives. Such filter is absent on the Slash. Some brands even make these special grid removable and have a dedicated connection system, so users can connect a hose that direct the fumes through an opened window. Customer’s health, filters, and the possibility of hose connection were simply not part of the Uniz design process.

Maybe you should have answered this, instead of suggesting to “put my printer in the bathroom”?
Development of the Air Clean Unit
We’re working on it, although the resin is safe and passed many certificates, we still want to reduce the smell by improving the formula and developing an air cleaner unit.

The resin is safe and pass MSDS, REACH, CP65, CPSIA certificates.
Yes, there is vapor of resin but no visible fumes. The air flow input from grid at bottom of printer and output from rear grid. Currently, there is no filter at rear of printer.
UNIZ had considered this issue and is developing an air clean unit.
This is a so much better explanation than Uniz themselves… thank you.
The resin may be safe, but still it stinks 😉
