I'm new to S3D but not to 3D printing in general but I wouldn't get close to calling myself an expert ...
My question has to do with adjusting the top surface of the model. Ideally I would like a smooth water-tight surface. I am actually trying to make a vacuum seal with the top surface but it doesn't need to be perfect, just as tight as I can get.
One thought I had would be to print the part upside down but that brings some other issues along that I would like to not have to work around.
Are there settings inside S3D that would affect the smoothness of the top surface? I'm working with PLA at the moment as the heated bed isn't quite available yet to work with ABS which might be a better choice.
I am using an M3D Micro and it's working extremely well with S3D. I use different software than the standard M3D software which probably helps. Microprint is a Mac program that I have helped develop, especially the ability for it to work with S3D GCode files.
Any thoughts would be appreciated.
