ASA in general smells low.  Polymaker ASA seems to have much less odor than other brands.  I have 4 printers in one room in the living area.  I do nto smell ASA at all.

Hi,
I ordered a Prusa Core One L. I want to print large ASA objects. I therefore those the Core One L.
I need to place the printer in the basement. This space is not very good ventilated. There is one 120 mm opening to the outside world.
I want to print safe and take care of the toxic fumes. So I ordered the Core One L with the extra filter and fan.
But I do not think that is enough.

So I was thinking: what about connecting the output of that filter with a hose to this opening to the outside world so that all fumes are blown outside the basement?
Problem with that is that I will blow hot air to the outside world. Somewhere cold air will be sucked in. So the basement will cool down and I think the printer chamber temperature will drop too.

How to prevent this? I have a heat exchanger laying around. Could that help? Then I would need some input to the printer chamber to be able to blow the preheated air into the printer. But that will still be a relative low temperature. So you will get all kind of cold air flow inside the printer chamber. Not good.

Putting the whole printer inside a second chamber that is connected to the heat exchanger may be an option? But placing the whole printer inside a chamber that is significant warmer than standard environment temperatures may be not good for the printer. The electronics (and especially the power supply) is not designed for that. Resulting an fire danger.

So what  should I do? Any ideas?

 

The sensitivity for the smell of ASA/ABS seems very varying among individuals, I cant stand ASA or ABS. The IKEA starkvid air cleaner with carbon filter seems to take care of it quite decently in the garage.

what do you see in the FW?

Since the Core One L is not available in kit form, I'm wondering why Prusa decided against including an option for a actively heated chamber. 

They need to increase the chamber temp so it can compete with the H2 platform. Adding the INDX is a great step but they are lacking a better AMS type integration, in the sense that the filament management needs to be simplified. I would also like to know is the temperature going to be managed now that the INDX version is going to be taller (lots of PTFE tubes poking up). 

Lots to thing about, I really hope to see some good progress. The INDX is not enough at the moment.

Any leaked info as to whether PRUSA is going to be releasing an active chamber heater for the Core One. As much as I like the mods people are making, I would never trust my printer with one of those and that is limiting for my workflow....I am not interested in any mods that could potentially set my house on fire.

This is the only thing stopping me from selling my H2D and fully moving into the PRUSA ecosystem. Right now, the H2D is vastly superior in heat management. It can reach 65 degrees in less than 5 minutes, and automatically adjust this temp throughout a print job. 

 

 

While I understand and partly support being skeptical towards mods, you shouldn't discredit all of them. A lot of mods made for Prusas (and 3D printers in general) are made by people who are engineers by trade.
