You can now 3D print plates, cups and other food containers as well as children toys using food-grade Polypropylene (PP) filament. Available at German RepRap, the new Polypropylene (PP) filament is semi crystalline thermoplastics and being produced according to US FDA regulations and the relevant EU standards.
Similar as some food storage containers, PP-based models has a soapy surface and high level of flexibility. For the best results make sure your printer temperature has been set to at 210°C. PP sticks well to unheated print bed with a thick first layer. Better adhesion to the print bed can be reached by pre-heating the print bed to 80-90°C.
The PP filament can be used with all printers that have a 3mm hot-end. It is available in black colour and a 2.1kg spool cost 99.95 EUR. Th 750g spool goes for 54.95 EUR.

I'm trying to 3D medical grade plastic polypropylene. What is a good machine for this and finding a lab to print prototypes? Accuracy is key. Thank you.

Just started using a spool of PP, seems easy enough to print with, it's not too flexible for my bowden tube, my ultimaker is powering through it. btw I'm not using a heated build plate, and on smaller prints it doesn't seem to warp at all, haven't tried anything too large yet. Any idea if this stuff is hydrophilic or not?

Can I eat the plastic? I like the printrbot

The plastic may be food safe, but that doesn't mean the prints are. As long as they still have those little ridges in them where bacteria can thrive your printed object will not be, by definition, food safe. Also, if you have a brass extruder nozzle you're introducing the filament to lead as it prints. But if you can find a way to finish the prints and if you're using a steel extruder nozzle then, yes, you can print food grade sporks all day long.

MadeSolid's PET+ filament is also food-grade, FDA approved, etc. Comes in several colors and diameters too. http://shop.madesolid.com/products/madesolid-strong-filament-1-75mm-1-lbs Full disclosure: I work for them

@Opertum: You are right. Thanks. Fixed.

Print bed set to 210??? Wow, mine has a hard time getting to 110 on a cold day. Perhaps they mean Print temp is set to 210.

Oh, at first glance I thought we can now 3D print jelly bears. What a disappointment >.<
