If you take the back cover off the q1 pro - you will find that the fumes are not really sent out the exhaust vent. The fumes are just dumped into the back space of the machine and end up coming out the power supply vent as well. So you need to add an internal duct to channel the chamber exhaust out the right vent. This will also keep your main board and power supply cooler.
Thank you for pointing this out, I removed the back panel and definitely need that duct you mentioned. I can also see a lot of gaps that could be sealed better.
It is for most things, but I personally don't like the shiny finish, and it can be brittle, I've tested with PETG before and it just didn't work out for me. Small features broke off easier than with pla or abs.
It itself is made of ABS although there is a sturdy steel frame. ABS has a glass transition temperature of 105 °C. maybe 75- 80 chamber temp would be achievable without replacing the ABS panelling and other plastic components with higher temp alternatives but i think water-cooled motors and hot end might be required. I don't see much reason to extend the thermal head room 20 °C. Maybe QIDI will make a higher temp machine in the future for higher temp plastics.
Good info. I’m curious if the X1E can exhaust the fumes while keeping up the temp. But of course it’s so much more expensive. And do you need to run the fan at 100% speed? All you need to do is run it enough to create a negative pressure. I think it would be interesting to do some smoke tests with an automotive smoke machine and see how much it leaks at different fan percentages. Also if PETG is too shiny I wonder what the finish is with PCTG. I hear you can control the finish with temperature. Similar properties to PETG and ease of printing with low VOCs and no requirement for a heated chamber. I do love ABS though. Especially Bambu’s ABSGF. And ABS can be cheap so I think you’re going with the right method.
I have a 10" 1200cfm exhaust fan that also creates some negative pressure in my workshop, so I just run the printer exhaust at 100% just to be sure its getting good suction. I dont mind running it at 100%, may even get a more powerful fan just to make sure Im really getting all those fumes out.
