Most clear packing tape is actually polypropylene I think. Any way I am using clear packing tape from my local supermarket and it works very well.

The only problem is that when an area has been printed on the adhesive sticks better to the glass than the tape so replacing the tape leaves behind a sticky mess I guess acetone should clean that off but I ran out...

I am extruding the PET @ 145 degrees and the PP @ 140 degrees.

the PET does not does not stick at all. Right now I am test printing onto a ziplock bag that I glued down to the build plate.The build plate is cold and it appears to be sticking- at least for now.

But perhaps what you have is a different flavor of PP. I know that Sanjay at E3D printed POM on a POM sheet because it wouldn't stick to anything else.

I am thinking about finding some of these - Avery Easy Load Top Loading Recycled Polypropylene Sheet Protectors - and taping one to the build plate. The PP should stick to itself - does that make sense or am I missing something?

Worth a shot!!  Less messy than contact cement!

Take a read on this though:

I suppose a coat of contact cement over kapton (for easy removal) is worth a try, maybe a test print on a 3" x 3" spot centered on the print bed.

I started out with the build plate cold and increased the temp by 10 degrees until it started to stick at 120 degrees. At 130 I figure the PP will start to deform - so I stopped.

I have tried with and without kapton tape and with and without hairspray.

I poured the PP pellets into the filastruder and out came some nice transulent PP filament. It is smooth and flexible. But I am having trouble getting it to stick to the build plate. I can only think of three possible solutions.

1. adjust the nozzle temp/speed/build plate temp settings
2. add some substance to the build plate the PP will stick to
3. mix something (like ABS) with the PP and make a blended filament

I have done my due diligence 10 second google searches, and am currently running thru different combinations of temp/speed settings. Any guesses would be apreciated.

I am just now extruding the PET pellets now, we'll see how that filament comes out.
