Not sure many are going to understand what "lakhs" is. I had to look it up myself. It appears to be from a south Asian numbering system equal to 100,000 or scientific notation 10^5.

Therefore 16 lakhs would be 1.6 million polygons so one level of subdivision would be 6.4 million polygons and two levels would be 25.6 million polygons.

So yes you have a very large model indeed. I do not do any 3D printing but I have a friend and he uses STL (stereo lithography) format and commonly outputs models with tens of millions of polygons. You might try that.

The format you are trying to export to may not be the only issue though; Your system may simply not be able to handle a model this large in which case worrying about an export file format is really moot. Your options then are reduce the size of the model or increase the specs of your hardware.
