Face corruption in MakerBot


#1

I have created a small model about 3mm deep. The object looks good in the web app, but when I import the downloaded STL file into MakerBot several of the faces are incomplete. Any thoughts as to what causes this “corruption”?


#2

Can you share the model .skp file?

At a guess, it may be that you are inadvertently creating edges that are too small for SU to work with.

Search this forum for “The Dave Method” for a workaround. Essentially, create a component at the right size, make a copy, scale up the copy x100 Oor x1000, edit the scaled up copy, then delete it. SketchUp won’t create very small edges, but will preserve them when scaled down.


#3

Divide faces into smaller, it should help.


#4

We are still guessing without a model to look at - can you upload it here? If it is too big (over 3MB - seems unlikely it will be bigger) then use a free file sharing service like Dropbox, OneDrive or Google Drive and provide a link.


#5

Here is the similar issue with Zortrax Z-Suite. To avoid this you should divide your faces with additional lines.

ps. new Z-Suite solved this problem.


#6

@robertjuch, what additional lines? To triangulate?
The blue object is quite dark, spinning fast, so I can’t see any difference between both white and blue objects.


#7

I’m a bit lost too. Not sure how adding edges would help. Particular to a 3mm model as you are only making even more tiny faces.
I suspect it is either tiny faces missing or reversed faces not being recognized.
Either way it’s all just guessing unless the OP bothers to come back.


#8

Sorry for to fast spinning. And yest triangulation is a better term (some times quads are enough).


#9

I am wondering is there is an issue with small gaps or internal faces, or something… Can you share that SKP?


#10

I will share you file soon, but this is simple solid without reversed faces and internal edges. This is definitely slicers problem.

Solid model.skp (149.6 KB)


#12

Yeah… I was able to load it into Cura, Slic3r, and Preform without issue… Looks good in MeshLab, too…
