A very smooth printing filament. Now, I have try polishing & adding patina!
Love the filament, didn't love the cardboard spool, most of the filament is now un-spooled as I horribly failed trying to transfer it to a real spool(my fault)
I made a rusted bridge for battletech with this stuff. Super happy with how it melts into other pla for the AMS on my bambu p1s
Cool variety of materials, I'm always excited when I get the notification a shipping label has been created!
This truly does look like denim! It has hints of subtle different shades of blue, kind of speckly when the finish isn't smooth. Hard to explain, but it looks exceptional. One of my new favorites of the week.
While I know Protopasta is not a value brand, when you print with it, you see exactly where the $ went. Unlike other "premium" brands I have used, I have never felt like my money would have been better spent on more filament after using it when I use Protopasta.
I have had a few Protopasta colors over the years, and this one is one of my favorite so far! And HTPLA has quite a high heat resistance, I had to crank up the temp on my soldering iron to set the threaded inserts in HTPLA, after setting them in PA6!
You couldn't order from a nicer group of people! We've purchased hundreds of rolls from Proto-Pasta and they have never let us down!
Given that this is my color, I may be biased, but we love OOD Orange! We've printed hundreds of rolls over the past few years, and it's always been consistent and reliable!
Easy to print to the color change works really well.
