Hi,
I just received my P1S and although it’s not loud I would like to close the door while printing. I heard with PLA it can get too hot and is not recommended. Will I see noticeable defects in the print or should I just stick with leaving it open?
Thank you!
Maybe. If so, you could take the glass top off instead of leaving the door hang open.
I’m just trying to reduce noise but I think it would be the same if not a little less noise… I also have a AMS on top.
There are people printing PLA with the door closed. But like most things when it comes to 3D printing, you’ll need to experiment and see what works best for your unique environment.
Run the same print with the door open and then again while closed. Compare them and see if the door position makes a difference.
I’m one of the “people” that print PLA with the door closed. Always have, always will. The room temperature where I have my printer stays at about 70-71F. Too chilly for fresh printed filament. Unless you want your model popping off the plate in the middle of a print. 
I print open and closed, just depends on how I feel that day. I’ve never had issues with either, although I almost always have the top propped open. Not that noisy.
Using the Cool Plate, you never need to open the door or lid. Unfortunately that plate seems to be EOL now? I have no idea why, that plate is terrific. I’m lucky to have 2-3 spare sheets for mine.
When using the textured PEI plate, I’m printing with the glass lid off for larger or longer lasting prints with PLA due to heat creep. For smaller stuff I don’t care and leave the door and lid closed.
Other than that, I always turn off the aux fan completely due to warping issues.
I’d suggest using a cold plate instead, if leaving the door or lid open is an issue.
I usually leave the aux fan at 10% rather than turning it fully off, exploiting the colder air under the hotbed.
I just received mine too and I am printing several brands of PLA with all closed and not using glue. No problems until now. Room temperature is around 23 degrees celcius. I am right now printing a 11 hour job (full plate) and after 6 hours all seems good. I am on my 2nd day after the unboxing.
I’ve similar concerns before. But been printing PLA with P1S door closed have no issue with me at all for months. Though its winter here (10 Celsius at night) and I left it in garage so heat build up seems no issue to me. Though it maybe during hot days result in heat creep issue and blocks nozzle until sometime fan is not able to bring the heat away. If you’re worry about noise more than a few steps of unclogging the nozzle, there’s no significant issue there, just keep watching print status when you’re on long print.
These stickers on the plates don’t last forever. I also often print on these Cool Plates and am already using the third one in two years. Most of the time, the stickers have imprints from the prints, the nozzle works its way into the material. Since I realised this, I only use Glue Stick on the Cool Plate, which helps. I think the X1C came with extra stickers for the cool plate for a good reason.
I prefer the door closed to mitigate noise, but I tend to agree that having either the door or top lip venting the heat (open maybe 1 inch) has yielded me some better results.
Another great option (for us wanting chamber closed for whatever reason) seems to be the ICE plate. You can print PLA on it without heating the bed at all, and PETG/ABS/ASA at 30°C. It doesn’t support TPU though. I’m planning to buy one of each plate from DarkMoon once all of them are in stock at the same time (saving delivery costs).
when printing with PLA on the P1S, do people turn the AUX Fan and/or the Chamber Fan off if printing with the doors open? i assume its always good to have the Part fan on?
The part cooling fan cools the filament after it has emerged from the nozzle. It directly cools the layer that is currently being printed. This can be helpful in various situations, such as with overhangs or bridges. Basically has nothing to do with the open printer.
I have always printed pla with the door closed and have never had a clog from it
Smart. Great idea. I made a note of that one.
Suggestion: Search for a riser for the glass top. Download and print two. Use both on the back of your glass to lift it, allowing the hot air to escape.
