Printer Enclosure Question(s)

[galaxybeing]

I have an original Ender 3 and a Neptune 4 Max. Most of what I've done is PLA, with some small amount of ABS, which is just awful IMO. I'm told many of my warping and layer separation problems are due to no enclosure. So here's my question" Running a printer for 2 or 3 or 4 days on a job in an enclosure, doesn't the printer bake itself half to death? You would think on a 3 day part you're making, that at some point, thermal runaway sets in and the printer won't be long for this world. Thank you.

I operated my enclosure at 80-100F this is not above the 3D Printers standard operation temperature.
The main goal for the enclosure is to stop the cool breezes from blowing across the models while retaining a constant temperature during 3D Printing.
Any temperature changes in this environmental chamber can negatively affecting the quality of your prints.

My 3D Printer environmental chamber had a door across only the upper front allowing the heat to remain above heated bed.
A small fan vented to excess heat to maintain constant temperatures.


This worked for me while 3D Printing ABS, it also help to vent the fumes outside.

Never printed a 3 day part.. my build volume is only 8x10x8.. My enclosure has no extra heater anymore, it is no needed. For ABS the heat of the bead is enough. Highest the temp inside gets is 100F. My electronics are inside the enclosure and the PS is outside. ABS requires the filament to be dry, a good material for adhesion (Original Buildtak is great for ABS if you are not experienced) ABS is not awful or hard to use but does require a perfectly flat build plate or a touch sensor with accurate height map. Also .1-.2 layers height is difficult with ABS if you don't have any of the previously mentioned things.. For 3 day prints, I would much rather use a .75 or .95mm nozzle and .5 or .6mm layers heights and get the job done in 1/3 the time..
As far as building an enclosure, make sure you use lift off hinges on all the doors so you can remove them when you need to..

Should have included a case photo also here is one.
My hinges are on top and lifted up no heater just a vent fan on low speed.
Two thermometers one behind each printer single open space for both printers.

Bed Temp 96C
Nozzle Temp 323C
Layer Height .28
Print Speed was max for my Hictop 3DP printers
