Interesting outer texture

I have been surprised by the fabric-like texture you can see in the image below:

It was the result of printing this object with 0.2 mm layer height and 1mm layer width on an otherwise standard Prusament PLA MK3 profile (PrusaSlicer 2.2).

The object had two perimeters on that wall and it was this model:  https://media.prusaprinters.org/media/prints/61818/stls/663949_59c16873-b37f-4901-ab53-2a81766c26d3/v3.stl#_ga=2.188764003.938084368.1620460043-1956480792.1612352463

Looks almost like carbon fibre.

Very cool 👍

Tank you very much!...

Yup.  looks like carbon fiber.  What filament did you use?

Hi Chuck,

It was the Prusament Galaxy Black PLA filament.

Thanks.  It looks very nice.  I have a roll.  I might try to print this.

Bear in mind I reckon it is the wide layer width that causes it, not the filament.

 

A couple of closeups more:

I'm curious how you oriented the part to print - or did you simply invert and use supports for the "bottom" surface?

@tim-2

I printed bottom-side up.

@misan

Are you showing the bottom side or the top?

Would you be willing to post a .3mf for us to look at?

 

I'm interested in that texture you've created and would like to explore it.

I just took my regular 0.2mm profile and set everything to 1mm extrusion. Got the texture shown, more or less, but only on the thinner walls. Sort of cool. I suspect setting only infill to 1mm will get the same effect. Though, setting everything to 1mm sure sped up the print time... lol.

I printed handle down, and bridging got me (bottom inside of cup is loose strands).

I rotated it in the base till I got the bridges crossing the shortest side.

Glad to know it was not an oddity of my printer/firmware.

The side I am showing textured is the vertical walls. It is almost of all of them, only fading near the layer change seam.
