Hairy and brittle, Help

Recommended Posts



So this is happening, and I've tried everything from speed to heat and I cant figure out why it is doing this.

This was with the following basic settings:

Layer Height: 0.1

Shell thickness .8

retraction enabled

Bottom thickness 0.6

fill density 100

print speed 20

support type: none

Platform adhesion: Brim (10)

Nozzle size: 4mm

Does anybody know whats wrong?

First check infill speed - make sure it's set to zero. That alone could explain everything if it's a faster value than the rest of the print.

20 is pretty slow so should give good results but if you are gonig that slow you can print much cooler than normal - try 190C for PLA if printing that slow. Or is this ABS?

Fill density 100 is probably a bad idea. PLA and ABS are incredibly strong. Try something less than 25% as you get better infill patterns there - try 24%. Still incredibly strong.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
