Problem with 3d printing

[christiank21 1]

Hi,

after many 3d printing with Ultimaker 2, I tried to print this small object .See the picture below.I used Cura version 15.04.6.I attached this pictures (in the pictures you see circled in orange).

Below are settings in Cura version 15.04.6:

Basic

Quality

Layer height (mm): 0.3

Shell thickness (mm): 0.8

Enable retraction: selected

Fill

Bottom/ Top thickness (mm): 0.6

Fill Density (%): 20

Speed and Temperature

Print speed (mm/s): 50

Support

Support type: None

Platform adhesion type: None

Machine

Nozzle size (mm): 0.4

Advanced

Quality

Initial layer thickness (mm): 0.3

Initial layer line width  (%): 100

Cut off object bottom (mm): 0.0

Dual extrusion overlap (mm): 0.15

Speed

Travel speed (mm/s): 150.0

Bottom layer speed (mm/s): 20

Infill speed(mm/s): 0.0

Top/bottom speed(mm/s): 0.0

Outer shell speed(mm/s): 0.0

Inner shell speed(mm/s): 0.0

Cool

Minimal layer time (sec): 5

Enable cooling fan: selected

What can I do? How can I improve? Thank you very much.

Bye,

Christian.

You have underextrusion. What material is this? PLA? Usually PLA doesn't peel off like that but that's common with ABS and easily fixed.

Still - what material is this and what temperature (temperature is set on the printer, not in cura).

I think the default temp is 210C and assuming PLA and with .3mm layer times .4mm nozzle times 50mm/sec that equals 6mm^3/sec. That's a bit fast for 210C and PLA. Try raising the temp to 220C and making your layer height thinner - try .15mm also slow it down a bit to 35mm/sec. That should fix much of the quality problems.

I used a PLA not ABS. I try your settings.Thank you
