Check out the “Infill Angle Increment” option in Craftware from CraftUnique3D. Both infill @3% see the difference! Good for supporting top surfaces where dense infill is not required.
I think it’s good for supporting the sides, and not that good for the top as the original.
@Peter_Csaki Incorrect, it is much better at supporting the top too. Especially if a printer is not very good at bridging in between the infill paths. We are not talking flat horizontal upper surfaces here but shallow convex shaped ones.
A printer that can’t bridge well should be calibrated. This increment angle is interesting looking, but I don’t see how it helps bridging in a meaningful way,
It helps bridging when the printer “should be calibrated” 
I can see where this would be very helpful, particularly when I do fast test prints for sizing prototypes. I tend to use low fill with only 2 top layers and go as fast as the printer can manage.
@Steve_Wood_Gyrobot I see, you are right. I assumed flat top surface.
Customizable support is by far the best thing about craft ware seeing as it’s free!
Nice. 3D sprograph fill!
@Tom_Carson And the super fast slicing time too, and the great graphics, and etc,etc.
Yes, it looks very nice, but I can’t seem to find a setting for the nozzle size?
@Rien_Stouten The “Extrusion Width” is the diameter of the extrudate exiting the nozzle which is the same as the holes diameter of your nozzle for the purpose of this software.
@Steve_Wood_Gyrobot Interesting. I was thinking the extrusion width would depend on the ratio nozzle size - layer hight.
@Rien_Stouten and it also depends on extrusion rate and speed percentages which are also modifiable.
Okay, I wil give it a try. It sure looks promissing.
