I want to print a model on a special printing plate so that the effects are visible in the model.
But whenever I print without a glue stick, the model slips on the plate. I also reduced the speed of the first layer and the filling to 10mm/s, but unfortunately the object starts to slip.
If I use a glue stick, the model sticks, but I no longer have any effects in the model, they are no longer visible.
How can I solve the problem?

Did you try washing the plate?

If you’re not using glue, you might need to raise the bed temperature.
For example, I can print TPU as low as 35°C when I use glue, but without glue, I need to increase it to 80°C. I’m using a Carbon Fiber Plate from WhamBam, which actually recommends 50°C, but I’ve found that I need to go significantly higher than that to get good results. Are you using Bambu Lab’s 3D plates?
I always clean the printing plates very thoroughly. In the picture you can still see the residue of the glue stick on the printing plate. But if I use the glue stick, I no longer get any effects in the model.
Thanks for the tip. Unfortunately I don’t use an original printing plate
I am also having problem with a smooth print even when cleaning the plate correctly
Ok… let’s slow down here please and back up.
Let’s start by first covering how these prismatic plates actually work. They rely upon microscopic fissures and grooves cut into the plate. It’s those tiny microscopic ridges that give it the holographic appearance when you hold it up to the light.

It is this ridges that transfer to the bottom surface of the print that create those cool affects. By smearing glue on the surface, you plug up all those ridges and that’s why your prints are failing to show the graphic on the side in contact with the build plate.
Remedy.
Build Plate Hygiene
At this point, there is a small chance that you ruined your plate. What you’ll have to do is is use very hot scalding tap water at high pressure along with dawn dish soap and clean the plate as best as you can. DO NOT SCRUB THE PLATE WITH ABRASIVES!!! You will damage the ridges more. Use a soft cellulose sponge or microfiber cloth. Paper towels are also very effective. Repeat this process multiple times until the rainbow affect returns and then test it.
Proper Print Settings.
Plate separation is generally caused by two dominant reasons. The first is poor plate hygiene and the second is a temperature too low. Increase you plate temp by 10C and try it again. It’s not a crime to increase it 20C. Turn off the initial layer fans too.

Smooth might require a higher bed temperature—could that be the common factor here?
What bed temperatures are you using?
Which material are you printing with?
Has the material been dried, and if so, for how long?
As @Olias said, bed temperature is a key point.
On my Carbon Fiber Plate I need higher than recommended to make the filaments stick to the plate, no matter what material.
You can also heat soak the plate, sett the intended bed temperature for 5 minutes before the print starts. Might help.
Thank you so much for the fantastic description. I’m currently printing at a higher print bed temperature, without glue and the model is sticking to the print plate. Thank you so much for this tip!
