Problem with TPU

Posted · Problem with TPU

Hi everyone! I have some problems to print with TPU95A, I try literally everything but it seems nothing change. 

I would like to obtain a simple parallelepiped scaffold (dimension: X=10mm; Y=10mm and Z=2mm) but the last layers printed are not perfect as if there isn't a good connection. 

I have changed a lot of parameters, read all forums and topics but nothing.

The principal problem seems to be the non-adhesion between the last layers, as you can see in the pictures.

There are some parameters that I use/used:

Layer height: 0.1 but also try with 0.2 and 0.05;

Line width: 0.35/0.27;

Infill line: 1 mm;

Pattern: grid;

Temperature: 230° C (also 235 and 240);

Speed rate: 11 mm/s;

Build plate temperature: 60° (also try with cold plate and 70°);

Flow: 100% (try with 120%);

I also have modified some parameters for extrusion (also try without it) but nothing works. In addition a put some stick on the plate to have a good adhesion.

Any suggestions?
