I’m a beginner 3D printing novice. I have done about 5-6 successful prints so far, and my last two have technically come out fine, but they seem very brittle. By brittle, i mean that both prints have snapped cleanly into several pieces, not by design. My extremely novice research has led me to think it’s a layer adhesion issue - it is very cold here where I am right now, and I print in a non-climate controlled shed because of reasons. I do have an enclosure though, so i tried printing my PLA at 205 instead of 200, but same result. Is there a better way to correct prints snapping apart like that? I don’t feel like i used any excessive force.

    My apologies, that room temperature is around 25° f, which is -4c. It’s very cold

    yeah. so, what’s your enclosure like? is it fully enclosed? one of those tent-thingies?

    I’d suggest considering some type of insulation. Blankets work- if it’s MDF or mealmine or plywood, stappling them inside. If… insulation is problem… Blankets over a big-enough cardboard box work (just be aware of melting/fire risks. Cotton>synthetics. card board is okay. my old I3 prusa had cardboard under the heat bed instead of cork or neoprene for a long time. Try to keep it small enough to just fit everything inside. (cut the top flaps off and put it over upside down.)

    The heat bed should be good enough to get it most the way there- and if you find it takes too long to heat up the inside… a heat gun can prime things nicely.
