Prints are now sticking too well to the bed. What to do?

I'm a beginner. I've a Printrbot Play with a heated bed add-on. I'm using it exclusively with PLA. It worked great initially, but then I took the nozzle out and put it back in, and the Z calibration was lost (and I didn't know the calibration was a…

Why does hairspray work as an adhesive for ABS?

Since I have a 3D printer, I worked primarily with printing ABS. I tried multiple methods for adhesion (various soluble glues, ABS juice) but always had the most success with hairspray on clean borosilicate glass, as long as I print with a bed…

Can't get print to stick, no matter what I try

I'm new to 3d printing, so I might be missing something obvious. If so, please let me know. I printed my model successfully yesterday, but today I'm trying to print the same model and the first layer refuses to adhere, which means at best several…

Lines of PLA not sticking to the bed

When I am printing objects that have a lot of surface area on the first layer parts of that layer will rise up causing there to be gaps in the first layer. Here are two pictures. The first one was printing with a raft and the second one was without…

Second layer: gaps, poor adhesion - why?

I'm seeing the following pattern on my Prusa clone: The first layer prints OK, layer adhesion to the bed is good. The second layer shows the weird gaps. On larger pieces, or with an increased feed rate, it sometimes gets so bad that parts of the…

Troubleshooting poor adhesion at the edge of the bed

I've been printing for a week now on my new printer and have been getting great results, including great adhesion. However, most of my prints have had a fairly small footprint. Now, I'm stepping up the types of items I'm printing, and I've started…

Why doesn't PLA stick to heated bed?

I have a basic Creality Ender-3 with a black rough bed cover. I'm printing with PLA. After assembly, I printed 3 or 4 small toys sliced by Cura with basic settings. All were printed very well! However, after that, extruded filament would not stick…

How do skirts aid print bed adhesion?

In cura one of the options under "build plate adhesion" is "skirt", which seems to simply print a loop around, but not touching, my print. How is this supposed to help my prints stick to the bed?

Right now my heated bed is down and I had no time to try and fix it and I am trying to print something for a friend. I am having the PLA lift around the edges which I have NEVER experienced. The glue is not helping like it did with the heat. And I…

Turning off heatbed for the last few layers. Good idea or not?

My heatbed won't let go off the prints until it considerably cools down. The cooling process takes decent amount of time. I was considering putting the M140 S0 (sets heatbed temp to 0) somewhere near the end of the printing process, so that when the…

One corner never sticks

I am new to 3D printing. I thought that the black surface of my print bed was supposed to keep things stuck without additional tape, spray, etc. However, every time I print something, this same corner, and only this corner, detaches. Any advice on…

PETG layer adhesion

I've been playing around with PETG for the first time, and everything seemingly worked right just from the start - clean prints, no stringing, no bed adhesion problems, no warping or dimensional accuracy problems, etc. As expected it prints a lot…

I have been looking at getting some painters tape to use on the glass plate for better print adhesion, and everything I read suggests the blue painters tape, such as this: However, this white tape is considerably cheaper: This looks like normal…

POM filament not sticking to the build plate?

In the creation of the process of printing my own bearings to reduce noise, minimize play/tolerances and size the bearings to the actual size of the application, I obtained a spool of Polyoxymethylene (POM) or also known as Acetal or Delrin. This…

Adhesion problems with masking tape

I have been playing around with the bed for a while and I still can't get the first layer to stick properly. I think I am getting the bed leveled good, I use the paper method. But yet I find myself with the filament lifting off and getting pulled…
