PLA Lamination Problem

asked Jun 27, 2014 in 3D Printing by Arifin (1,390 points)

Please, help me. The layers remain intact without merging while I print 15mm cube. They seem to be individual layer attached loosely with each other. Therefore, 15mm cube appears as a stock of cards. I attempted for using Extruder Temps "190 first layer/ 180 others" to "210 first layer/ 205 others" but found no significant change. I also attempted printing switching off the fan, and found no layer stuck and I got a wad of plastic. I used blue patient tape for printing.

I again and agaiin checked the Z height.  I have both 3D ABS and PLA w/heated bed. A fan and glass bed are also available. But I want to use PLA not ABS.



Filament Diameter 1.75
Extrusion Multiplier 1
Extruder 1st layer 210 C Other layers 205 C
Bed 1st layer 0 Other layers 0

Layer Height 0.3
1st Layer 100%

Perimeters 4
Generate extra perimeters when needed is checked
Solid Layers Top 3 Bottom 3

Infill 0.5
Fill Pattern Rectilinear
Top/Bottom Fill Rectilinear

Fan Speed Min 35 Max 100
Bridges Fan Speed 100
Disable fan for 1st layer is checked
Enable fan if layer print time is below 60 seconds
Slow down if layer print time is below 30 seconds

Minimum Print Speed 10 mm/second


What to do?

Hello Arifin,

You should check the belt's tension first. If the belt is loose, it might be skipping.

Then you should use temperature 195C. Keep the fan always on and 2 perimeters.

Thanks Robert for your suggestion.

I will check the belts and tighten them if loose. But, to me, the problem is in Z axis as I am using vertical de-lamination. X and Y dimension of the cube seem very square.

Except that, I might think that it would be extruder or temperature setting problem. I have tried a wide range of temperature but found no change.

I certainly will use your suggested 195C temperature and fans @ 100% on and 2 perimeters. I'll also try lubricant on Z axis rod. I hope that will work. I'll inform if that does not work. is a free printing support and help site for 2d and 3d printers.
