A while back I had read somewhere that inkjet photo printer papers had some kind of plastic coating to permit sharper ink prints. On my other Prusa type printer, I use sticky vinyl drawer liners as PLA sticks well to it, but the heat of the print makes bubbles under the vinyl and, on hard platform, after 1 or 2 prints, it gets damaged. The magnetic build plate used by @ibisonline for his Self-made Vinyl Cutter, gave me an idea to try magnetic base photo paper for PLA printing. I purchased "Gloss white magnet sheets" for inkjet printers from Staples.ca (Office Depot in US), 4 8"1/2x11" sheets per package for about $11 Cdn. So far I did 3 prints, and they all stick perfectly well without any glue stick. Also they come off easily by bending the 1mm thick magnetic sheet.
First test structure;
Second test structure, 110mmx110mm square, 0.25mm high. (image is noisy, not enough light). 1 Layer sticks very well,
Now I don't know how long the paper will last but after 3 prints the paper shows no damage or bubbling. I can see some print marks, almost like a thin film of oil residue but prints stick so far without any glue stick help. I'll keep printing on it to see how long one sheet will last. So far I am amazed!
Update: Paper surface got damaged on 4th print! I spoke to soon, it is not a good alternative!
