I recently convinced my employeer that we needed a Taz 5. It has been printing nearly daily since we got it–building parts for an enclosure in which it will reside. The enclosure includes a filter for scrubbing the nanoparticles and odors and a blower to do the work. Inlets will (for now) simply be “leaks” where the panels meet the frame, but it should still maintain some nominal negative pressure. If not, it will be upgraded to more filter flow capacity.
Moving on to the point!
The box fits snugly (not TOO snugly) around the Taz 5, but currently does not have any external holes for the electronics enclosure (which clearly has a fan and vent holes). There is probably a 3/4" gap between those holes and the external wall.
Question 1: Will this be enough to satisfy the ventilation (cooling?) requirements for the electronics during a print job? Or will things get too toasty? Those of you who’ve built hot boxes will probably know the answer. If I recall, I’ve seen some with ducts to the electronics fan. Temp in my office just inside one of the non-fan holes is about 83F/28C.
Question 2: Can I shove the power supply in the box too? It’s got a substantially loud fan on it and this would quiet it down a bunch. But since it has a fan, I assume it gets warm. Too warm? Quick thermocouple measurement says it’s dumping hot air at around 90F/32C or so which is pretty toasty.
Add the two above to a heated bed and warm lump of plastic and it might be too much. What do you all think?
