smooth the curves

Anonymous — Mon, 02 Oct 2017 04:25:26 GMT

the issue is when i open model in fusion 360 slicer it shows me all lines on model. i have tried blender auto smooth, it make model smooth but when i import back the model in slicer its the same, is there any way to smooth the model.i have purchased this model and using obj file. fbx, .tga, .ma, max files are available to me.

thanks

Have you tried to "subdivide" it in the Fusion 360 Mesh environment?

i don't know anything about 3d modeling , i m new to 3d modeling. i can provide you model

Just upload your .f3d here and I’ll take a look tomorrow

ok, thanks for your help, i need model to be in obj format.

… And you tried printing this and it’s not smooth enough?

This looks pretty good in the fusion. Try it and let me know how it looks...good, better, etc.

Under normal circumstance I would say subdividing a perfectly fine quad mesh is the ultimate sacrilege. Usually you'd import the .obj into Fusion 360 and convert it into a T-Spline and then into a PBRep. The T-Spline conversion takes a little while but woks and produces a smooth surface without any faceting ... obviously.

However Fusion complains about self intersecting geometry and does not convert it into a BRep. As such I would actually not recommend Fusion 360 for this. Attempting to fix this in Fusion 360 takes about 10 longer than in Blender and as a matter of fact in Blende you don't have to fix it at all.

You add a sub-d modifier to it and export as .stl. As the .stl is created directly from the subdivided mesh, any faceting left also follows the original topology of the model which a .stl created from a BRep would not do. Blender also has better 3D analysis tools that Fusion 360.

its better, but still lines are very much visible

I smoothed some of the face out but you can certainly concentrate on certain sections if need be. If you smooth the whole thing too much you really start to loose definition.

i m looking for this kind of smoothness, is there is a way to achieve it?

Yes. but not with Fusion 360. You can export a .stl for 3D printing directly from Blender. there are plenty of video tutorials out there that explain how to prepare 3D prints with Blender.

i m using slicer software

Yes, the input slicer software accepts is .stl.

i have used blender to smooth the model out and exported the model in stl format, but when i open that same stl model in slicer it shows me lines

A .stl is a still, a polygon mesh. There will always be mesh edges visible. There is no way around it. You can try to increase ht level of subdivision in Blender to make the mesh finer.

I would like to see the actual prints? Software can be notoriously unreliable when it comes to small details especially in an STL file.
