SoliForum - 3D Printing Community → Software & Firmware → What's wrong with my Slic3r?
I created a 3D object in 123D Design and Slic3r as well as simplify3d cannot slice it correctly. Can anyone tell me what's going on here and how to fix it? Somewhat a noob at the moment but I've researched and researched a fix for this. I've tried netfabb cloud, netfabb free, and meshmixer (not sure if I used meshmixer correctly) and still nothing works.
I have attached before and after slicing pics.
Any help is greatly appreciated! Thanks.
dont know about Mac versions. the second pic looks like some missing/inverted areas though
How thick are the side walls in the model?
What is your perimeter width set to?
Actually, maybe post up a couple of screen shots of your slic3r settings, the key might be hidden in there...

My sidewall thickness is 2.169 mm. I finally got it to work but I can't remember what I did. I think I ran the stl through netfabb basic and then via netfabb cloud. Is there any 3d modeling software worth using that will correctly make models for 3d printing so I don't run into this again?
Here are my slic3r settings. Also, if it helps, I have a DaVinci 1.0A running Repetier firmware .

I use tinkercad which is web based and must be used through chrome, but I have yet to have to repair a model before printing it.
If you're looking for different software, and want to try something a bit closer to full-on 3D CAD for free, have a look at:
* OnShape
* Autodesk Fusion 360
Both are free, reasonably well-featured constructive modellers, support assemblies, and can export to STL.
While potentially a bit daunting at first if you're not used to them, if you learn how to use these, you're pretty close to having the skills to use full-on CAD packages like Solidworks (call it a skill investment!).
I can't yet vouch for their STL export quality, but I was just saying on another thread how I've never had this issue once with a Solidworks exported STL (the creaters of OnShape have history with Solidworks).
Re walls:
I note you have your wall widths set to 0 (automatic) - perhaps consider setting these explicitly? Given you've got an 0.40mm nozzle, start with them all at the recommended 0.48mm, and adjust from there. Might also be a good opportunity to print a calibration cube (single wall) and check your extrusion is accurate.
Then when you design parts with relatively thin walls (< 2 x [perimeters] * [perimeter_extrusion_width] = 2.88mm), you should stick to a whole multiple of this setting (e.g. 0.48mm, 0.96mm, etc.).
FWIW, with my 0.35mm nozzle, I use 0.50mm perimeters, so the above whole multiples are nice numbers

Where do you get half size nozzles? Or does it depend on the hot end type. For my CTC Flashforge clone I can only find whole sizes of .4, .3, and .2. I have yet to see any half sizes anywhere.
unless everything is tweaked near perfect including filament used. some of those high speeds may prove problematic upon trying to finish a print error free. just sayin ;^)

I'm using an E3D v5, which originally shipped with an 0.35mm nozzle.

My stock solidoodle extruder shipped with an 0.40mm nozzle, but older models used 0.35mm.
I believe 0.40mm is slightly more tolerant of contamination than 0.35mm, and most users (including me!) would probably not see any appreciable difference in their use.
Sticking to 0.1mm increment sizes is probably the way forward.

Yup, 150mm/sec moves and 120mm/sec infill are probably on the high side, but it looks very intentional!
OTOH, the 30mm/sec perimeters are probably a bit on the conservative side.
Looks like you have a plan there, good luck.
