Sucsess! I upped the number of solid horizontal layers and kept it at 4 perimiters. I printed it at about 75% speed and upped the temp to 190 for PLA.

I should add only up your temp as a last resort if it is printing fine(layers bonding) otherwise.

I'd say something is off in your calibration. I've printed single wall cups at .3mm when I was testing speed and cool settings. They all hold water except for when I cranked the speed way up I got some loop gaps.

ABS should hold fine if you have everything set right.

Thanks for the suggestion. I want to avoid the acetone route as it can slowly leach out but I will try the temp and speed adjustments with the PLA that is currently in my printer and post results later.

Like Nickythegreek said use acetone.. acetone vapor bath works wonders!!! however if you don't want to go that route I would suggest turning up you extrude rate just a small bit and maybe upping the temp as well just a little

The plastics not really being food safe shouldn't really be too much of an issue when they are used as shot glasses as the liquid shouldn't spend very long in it. That being said has anyone found a food safe lacquer that works well with the plastics?

If you use ABS, use acetone to help make a solid surface. Either by brushing it on, dipping the item quickly in an acetone bath or use the acetone vapor chamber setup.

Keep in mind that none of these plastics are really food safe.
