Review on 🔩 SainSmart Metal Copper 1KG1 75 Copper Filament Printing: Enhanced Metal Impressions for 3D Printing by Eric Dailey

Love this stuff. Prints very well, finish is very good, has great strength, stiffness and layer adhesion when printed correctly. I would caution users with Bowden extruders or sharp-edged feed paths, but off the spool it is quite brittle as you would expect from a highly filled filament. I just hope SainSmart keeps releasing it to keep it available. The only thing to note is that the copper doesn't look like your typical plastic dye, it's plentiful so you'll need to floss and wipe off before changing to a new color or it will come out. also copper. So significantly more than would be expected with a normal color change. Again, it's not surprising if you've used high-fill threads before, but fairly standard material if you have them.
