Ok so I imported few objects, dynameshed them into one object that looks really clean and airtight but I want to know what if I go directly after this to 3D Print Exporter and export the model out as obj or stl, will the model stil be airtight for printing or do I need to do some other operation? Would appreciate some help with this
After dynamesh most holes are closed. But all depending on your material guidelines you will have to measure in real scale to ensure everything is watertight, enought thick and enought clearance
After everything is checked in most cases you will have to decimate your model under 1 million polys in order to print. After decimation i suggest to run close holes again. Then you can use 3Dprint exporter for your STL.
Regards
thanks!!
