<![CDATA[SoliForum - 3D Printing Community — Problems with Slic3r on certain models]]> 2013-07-28T03:38:31Z PunBB https://www.soliforum.com/topic/3335/problems-with-slic3r-on-certain-models/ <![CDATA[Re: Problems with Slic3r on certain models]]> One of the biggest thing with Slic3er and how much memory it takes and how likely it is to crash is the number of threads you tell it to use.

From memory the default is 4... but if you are doing a large STL file, you need to drop this to 2 or even 1 to reduce the memory and processor Slic3r tries to use for slicing alone.

Configure->Advanced->Threads .

The other thing in newer versions, is specifying the smallest resolution. Setting this to 0.1mm or 0.05mm makes slic3r do a simplification before it slices, discarding polygons that are below the printable resolution anyway (and therefore, irrelevant).

But changing the threads to 1 or 2 is the biggest impact in terms of making Slic3r more stable for large STLs - with the slight trade off of longer slicing times. Its covered to great extent in Slic3rs Readme/Help files .

Netfabb helped on some, but larger models seemed to still crash Sli3er.
Solution I found was to download Kisslicer, and use that for tougher models.

An example is a model I recently got from Thingiverse ( . In the object placement preview screen, it looks just fine, but when I go to slice it, it ends up all messed up. Ive tried messing with the settings in Slic3r, but nothing seems to help.

Any insights would be appreciated.
