I have a Makerbot Replicator 3d printer for my class. I am having issues when I save my drawing as an stl file bring it up in the Makerware software it decreases the size and I can't get things to scale. I have been in contact with Makerbot for several months and their response is now: "We actually may have had a bit of a breakthrough! Apparently there's something off about the way that Inventor exports files to .stl, and there may be a bug in our software when scaling. Whenever exporting to .stl, especially in metric apparently, Inventor makes the object 10% of the size. To correct for this, can you try scaling your model by 1000%, then exporting to .stl and bringing it into MakerWare? Send me a copy of the .stl either way, and let me know how it goes!" and "The issue is not something we can fix because it's not an issue in MakerWare. As I suggested, contact Autodesk support and maybe they can help you out!"
Solved! Go to Solution.
Attach your ipt file here.
Attach your stl file here.
When Save As *.stl click Options and set the correct Units (Inventor defaults to Centimeters).
