    Hi,

    Yesterday I do some tests with a new filament type for me :).
    Profill ASA
    Parts were printed with my C2 and of course no heated bed.
    The results were go but when I removed the parts from the bed they braked at approximatively half of height.
    Parts have thin walls 0.8mm.
    Same parts were printed in PLA and no problem!

    No wrapping, no shifting present on parts!
    Printing temperature 245°
    Speed 50mm/s


    Any idea or suggestion?

    Thanks!

    Patrick

    Usually layer separation is due to inadequate layer to layer adhesion. If you build chamber is unheated as in the C2 you can usually get better intra-layer adhesion using a slightly higher extrusion temperature.

    Bump it up to 250C and slow down to 40mm/s and try again.

    Ok I will try so!

    FYI the printer is in an enclosed cabinet and temperature during the print reaches 40°.

    By reducing Fan speed does it help? Currently at 65%

    Fan speed should be no more than 20%, most of the posted tests around the internet range from 10%-20%.

    They all also have heated beds that start at 115C and drop to 90C once the build was 5mm off the plate.

    :D

    I'm loving this from the SDS sheet on that filament:
    Well... there you are.
