We prefer STLs & OBJ's, but we can take a look at your other file types.
The .STL is like the .PDF or .JPG of the 3D world. It's pretty much a standard and it's what we work in. However, we may be able to convert any other file type into an STL on our end using our softwares.
There are times where we may not be able to properly export your file based on your file's native program and the amount of geometry repair needed, but we can certainly take a look to assess.
