The material specialist 3M tackles a problem that every owner of a FDM/FFF 3D printer has. A better print bed that stops warping.
The Japanese subsidiary of 3M now sells a special polyester print bed sheet that helps against warping and also makes objects easier to remove.
The special surface of the sheet has very small groovings that increases the size of the surface which makes the 3D prints stick better to the bed. This functions very well for ABS and PLA.
The 3M print bed sheet measures 210x180mm and can be cut to fit to the most 3D printers. It sells for around ¥2,000 (approximately 20$) at Amazon JP.
