Sculpteo has online hollowing tools which will empty out excess material from the inside of your 3D prints – these can only work effectively if the model is a singular shell.
In this webinar we take a 3D model that you (our viewers) sent to ask3D@sculpteo.com and corrected it such that it could be hollowed effectively.
Keep in mind that we also have online repair tools which can fix a lot of the problems with a 3D model automatically (such that you wouldn’t need 3DS Max). That being said, you have a bit more control when using your own program.
