problems when 3D printing makerbot and rhino files

[mchedraui17]

Hello,

I have been using rhino and the makerbot for 3 months now. However, Im having trouble printing my file on the makerbot. Im having two different problems that I can manage to fix. Everytime I open my rhino file on makerbot it shows some of the surfaces black, and in some other cases the entire model comes out curved and weird… Im attaching photos to explain my problem…

Hope someone knows the problem and can help me

Thanks

Michelle

is it a closed polysurface?

and have you tried slicing it in cura?

are you sure you re exporting in the right way ? try to check the stl.file opening it with rhino.

did you fixed the stl exported?

In rhino, do you have your back faces represented as a different color than your normal faces. You can check, in the display tab. Or another option is to run the command “unifymeshnormals”, after you convert your model from nurbs to mesh. Another reson it might be doing that is due to you scaling the geometry, you might want to set your tolerances higher in the ‘units’ panel, from .01 to .0001, this will help with the scaling issue.

Modeling in rhino is based on NURBS surfaces while 3d printing requires the files to be in stl format which consists of vertexes, edges and faces. The problem you are having is probably based on the export settings in rhino or errors in the model itself. Here’s a link to an article that may help you https://wikis.utexas.edu/display/SOAdigitech/Exporting+from+Rhino+to+.stl

Rhino may have an option to set how fine the exported STL should be. If it is not fine enough when exported you could be losing the detail. Upload the file to Netfabb cloud to see what it looks like or load it to Shapeways. If it looks distorted there then you have a problem with your export.

Hi everyone! I was able to figure out the problem with a friend. the problem was that I had the model in inches and when i exported to the makerbot and changed the units to mm it stretched the surfaces so much that it damaged the file… So I had to change in Rhino the model from IN to MM and then bring it to makerbot already in MM and now it works

Thanks to everyone who helped! I appreciate the time and the help

Happy to see you sorted it out, Michelle! I was about to share with you this guide of exporting files for 3D printing from Rhino that @Craftee put together. Check out step #1

That’s a really nice resource for file conversations to .STLs - thanks for sharing it in here!
