Hi,
Can someone please help and explain to me what is happening with my model?
Its a relatively simple model of a SW Rebel Symbol (2.5cmx 2.5cm) that i have created in and exported from 3DS Max as an OBJ. As you can see from the images below the model is clean and has ample surface smoothing using subdivisions (not mesh/turbosmooth) as i know this doesn’t work for 3D printing.
When imported to MakerBot Print, I calculate the time to print etc and it will show me a layer by layer preview of the model. However you can see very clearly the problem that it doesnt retain as shape resemblance at all. Why is this?
Any help would be grateful!
Regards
James
It seems that your file is corrupted in some way. Is there any way you can export the file as a stl. Using a different file type could fix the problem. Do you use any other slicing programs like Simplify3d?
Your stl/obj is corrupted, Download netfabb basic and use the repair function, export part repaired and import to makerbot
Other possible thing wrong is that the top of the model isn’t “welded” correctly to the sidewalls of the model. Or there is extra / duplicate faces and "bad polygons " try grabbing one or two vertices along the sidewall or top and pulling to see if any thing crops up.
Try a STL file, it seems to be the “new normal” of course, no support from makerbot will also be normal.
You didn’t send the OBJ, but it looks to me like you’ve got some flipped normals there. Not sure how to correct it in 3DSMax, but if you have Windows10 you can open it in 3DBuilder and, if it gives you a warning, run the corrective feature, re-save and try again. If you don’t have windows10 you can run it through https://service.netfabb.com/login.php . Last I saw this was exporting 3MF which, again, easy if you have Windows10, if you don’t you’ll need a converter. Angus likes Meshmixer. Makeprintable supposedly has his own solution.
I think that the real trouble lies in your STL file. Try checking the STL file and detect if the same is corrupted.
Sorted, exported as STL not stupid obj this time.
thanks all for your input
