Review on High-Quality Melca Black PLA 3D Printer Filament, 1Kg Spool, 1.75Mm Diameter With Precise Tolerance by Chris Lacasse

This is my first filament purchase from Melca and I'm impressed. The +/- 0.03mm tolerance seems to be met, whenever I check the diameter with my calipers it's within the proper range, most of the time it's within 0.01mm. With the price of these rolls, if this level of quality is kept over the entire roll I will be a customer for a long time. The free samples included with each roll is a nice touch also, it's about 6meters so enough for a pretty decent test print so you can get a feel for their other color offerings.
