So earlier today I found myself without any masking tape that I usually use to secure prints to my unheated print bed. Only a few masking tapes and some blue painters' tape work for this, and they're usually annoying to apply, annoying to separate the part from, create tons of waste, are one, maybe two time sacrificial, and will leave lines on the bottom of the finished print where the tape sides end.
Finding myself in such a position, I began to improvise, since I really needed a print at the moment, and couldn't just go to the store and get more tape. I did have some masking tape around, but it was too slick and my prints kept separating from it. This was when I decided that instead of covering the bed with tape, to use notebook paper.
I applied it to the bed by taping the ends to all 4 sides of the bed in such a way as to make the paper taut and flat against the surface of the bed, with no to minimal flap (it was about as smooth and level as regular tape). I didn't know if this would work, but I figured it might as the paper is fairly porous, and would make a good gripping surface for molten plastic. I started my print to find out that it did indeed stick, and that there was no issues with leveling or surface discrepancies. Any that did exist could likely be fixed with a simple calibration. It gets better though.
I had originally thought that this paper would have been sacrificial. The part would stick to it, but since it wasn't glued to the bed, I wouldn't have issues nearly breaking my glass print bed trying to rip parts off and sometimes even breaking them. Well not only did I not have issues, the part came right off the paper, leaving no scaring to the paper, and no residue on the part. The bottom of the part was incredibly smooth, with absolutely no lines, and no transfer of ink from the ruling of the page. The paper seems completely reusable, and I am wondering how reusable it is.
So this is the TL;DR: I want people to try this out, and see if I've actually discovered some new and amazing way to cover 3D print beds. The exact method is to cut a piece of notebook/notepad paper to the size of the print area, and then using short strips of wide masking tape, secure all 4 sides to the rim of my print bed, in such a way that the page had no bend nor curve in the middle and it is completely flat.
Does this work for you? I used PLA with a nozzle temp of 200C (standard settings). If so, what were your settings, what is your printer, what did you print (surface area being important), were there any issues with layers misaligning (more than usual), how easy was it to remove from the paper, did it damage the paper, etc. Report back, I'm really interested to hear about this.
