Print Failing in the middle and end

[AMGolf]

Printer: A1
Plate: Texture and cool tack (never works so that’s another post )

Filament: Sunlu Basic Green and Bamboo matte Black both failed.

STD settings with 0.4 nozzle with supports enabled.

Bambu Studio Slicer.

The bottom layers stuck, but when taking the print off the plate I threw that part of the print in the bin. It was connected with stringy filament

Hi guys I am a newbie and appreciate any help. I was printing this print in place hinge just to see if the tolerances were good and the print kept failing on one side of the model halfway through the print. At first the first layer wouldn’t stick on one side of the model. So I tried the cool tack plate. Same issue so I washed both plates in hot hot water with Fairy washing up liquid and tried them with a microfibre cloth.

The first few layers began to stick so I left and the printer and came back to find one side printed well and the other side failed twice in the middle. Spaghetti strings.

I changed the orientation of the model in the slicer and the same thing happened. Not sure what to do.

I have my printer in an under ground room so there is very little traffic and draft. I would say when I first got the printer it was printing everything great and the room was about 19 C degrees with 50% humidity, not is about 15 c degrees and humidity is about the same.

I used a step file but for some reason I can’t upload it here.

I would really appreciate any help and advice.

Show us a screenshot of the part in the slicer preview window

Thanks for the response. Is that anything in particular you want me to screenshot?

Could you share a screenshot of the slicer preview to see how the part looks when sliced? Also, what type of filament are you using? I had a similar issue once when I didn’t dry PETG enough. A screenshot of your model would also help to see the complete piece

Well the sliced part on the build plate in the Preview window turned in such a way to view the problem area of your part.
E.g.:

Btw you should “unresolve” this post here

Here are some screenshots of the Slicer preview. All settings were the default

I believe the print started to fail after this point

Here is the next layer

Not sure if that helps.

Ok thanks, now can you post a screenshot of the same preview but with the plate turned so that we see the part/build plate from below

[AMGolf]

Is this what you are looking for?

[Panamon_Creel]

thanks that last photo shows your problem, the failed section started printing mid air and not on the build plate.

So my question is, is it an error how I drew the model or should I have enabled supports? Thinking of it now maybe add supports to critical areas might of been checked. What is your advice to print the model again?

[Panamon_Creel]

I don’t know your design intend but from what I can see the two hinge parts are not flush on the bottom thus the gap to the build plate of the slightly higher part.
option 1: redesign parts to be flush
option 2: re-cut the part in Bambu studio so it is flush
option 3. if the step is needed then print with support

Thank you so much for your help, I will report back.

First of all thank you so much for your suggestions, you were spot on with the issue. I cut the bottom of the model to make them level and it printed perfectly.

The hinge is for box I want to print which with the lid closed is 140mm tall.

I guess I can’t print it with the lid closed as it will fuse to the bottom. It’s too big to lye flat and have the lid in the same plane as the box.
How would you suggest to print something like this, since the hinge is print in place.

Thanks again for your help

I was printing in Sunlu Basic Pla. Nothing fancy
