3D Prints Keep Messing Up

[smalkasian 0]

Every item I print turns out this way (see photos). I have tried adjusting temps (doing that right now) and cleaning the tip, but maybe I'm still missing something? All of my prints turn out very brittle and crackly. Just very poor quality. I have the PLA in a dehydrator keeping it warm and dry. 

 

Any thoughts or help? I am new to the 3D printing community so any explanation or advice is greatly appreciated!

 

Thank you so much!

This looks like severe underextrusion, which could be caused by a lot of factors: too low temperature, partially clogged nozzle, worn-out teflon couplers, incorrectly mounted bowden tube, dirty feeder, slipping feeder due to wrong tension, too high speed, wrong filament diameter or setting, too much friction in the whole feeding traject, spool wound too tight (often when almost empty), material decomposing in the nozzle, way too moist, and so on.

 

Somewhere on this forum there is a good list of causes (but I don't remember the name exactly), or google for underextrusion causes on the internet.

 

I made tests some time ago, and yours looks like an extrusion-rate of maybe 50%? (Pictures are a bit out of focus due to taken on a dark winterday, but you get the idea).
