11.3 Flaws in printed objects
1. If an object appears warped due to coming partially or fully
loose from the build plate during the print, take steps to
improve adhesion; see Section 8.2 for some ideas.
2. If objects are printing with rough surfaces, or with lay-
ers that don’t seem fully stuck together, so that the ob-
ject can pull apart, t h e temperature of the extr ud er may
have been too low; try increasing the temperature by 5°C
and try again. In particular, if printing through the Po-
lar Cloud, under “PRINT SETTINGS”, “BASIC”, adjust the
“Temperature”.
3. If individual layers, an d especially the top layer, look b ad,
another possibility besides too low a temperature (men-
tioned above in item 2), is that the filament is not feeding
smoothly and hence not extruding smoothly. Make sure
that the spool of filament is feed i n g easily and smoothly,
