Polypropylene Build plate

[rayholland 6]

Hi,

I was using those PEI sheets and my prints were sticking very well, but i had some problems with durability.

After a while the sheet was coming loose and/or i saw some damages on the sheet surface.

 

So, i'm looking for an alternative solution and would like to try a solid 4mm Polypropylene Plate as Build plate.

 

See:

Price is very cheep, just around 5 euro for a 254 x 228 x 4 mm plate.

 

But i have some questions (maybe someone here could give me some advice):

Would these plates be usable for 3d printing?

Do you guys think the prints will stick as well as PEI?

What max temp. could i use with such a plate?

Do they conduct the heat the same way as the glass plates?

Are Polypropylene plates as flat as the glass plates?

How about durability? I assume a 4mm thick plate will last longer compared to thin PEI sheets?

 

Oh, just a remark: I'm printing mainly with PLA and PETG

 

Cheers Ray

Why not use just the glass, maybe with some glue stick? In my opinion it is still the best way and works very well.

True, but i'm lazy. Don't want to constantly clean the glass plate when the glue gets hard

😉 - me too, but I only clean the glass from time to time, maybe every 30-40 prints. I use just a little bit of the stick and then distribute it with a wet towel to get a very thin layer.
