The cup looks great and your printer seems to be tuned quite well to produce the cup.
Have you tested it to hold boiling hot water?
I would extremely nervous using it with hot liquids, please be careful!

Looks great! What material did you print with? In addition to the hot liquid point that Eaglezsoar mentioned, if you printed out of ABS, then it's not food safe :-(.

I didn't really make it to drink from, just experimenting with "ABS" and it does have one spot where it leaks because I made it as light as possible and used minute infill and no layer base. There was one spot where I had it to hot on the bottom curve where the plastic burnt and that is where it leaks. Other than that it really looks good. Does anyone know if T-Glass is food safe. I don't like to print with PLA at all it looks to cheap and has not much glisten. ABS really prints good, the only problem with ABS is the warping and holding it down. I have to use Painters tape with slurry (acetone & ABS chips) to hold it down and sometimes the warpage pulls the tape up.

I am thinking about first putting down a 3 or 4 layer mesh net something like a small hole screen under all prints to see if that works any better. It seems the longer in length the print the greater the warpage. If I use the bed heated the parts pull the tape right off the glass.

I haven't bought any T-glase yet, but what I read indicated that it's FDA approved/food-safe. I plan to get some soon :-)

Keep in mind that while the MATERIAL may be food safe, the print you make won't be because of the layers - bacteria can hide in those little grooves.

Bah, what's a little bacteria ;-). Seriously, good reminder, Gene. There was a thread about that a while back that I had totally forgotten about!

Ya right a cancer warning right on the label of Neverwet. I'll experiment with mesh under the parts for now.

"Foodsafe" and safe for food use are very different things.

No, FDM parts aren't 'foodsafe' - meaning they don't meet the standards required in order to sell things to the public for consumption.

That doesn't, however, mean that it's unsafe to use.

Use the coffee mug. Just make sure you hit it with some warm soapy water and keep it dry when not in use.
