Prints well, nice appearance

I purchased the 50g sample coil and was able to print it without difficulty using a hardened steel nozzle at 210C on a glass bed at 65C. The prints were precise, pretty much perfect, and there was no need for any special settings beyond what I usually use for PLA. I did take care to avoid letting the HTPLA sit in the nozzle unextruded while hot, since this is probably an occasional cause of clogs. Printing the 50g sample did not result in any noticeable wear on the hardened steel nozzle. I annealed the parts in a convection toaster oven directly on the glass bed plate at 100C for 10min and that worked well. There was slight warping of a long straight leg, which is not a problem in this application but which is noticeable. I printed another leg and annealed it while it was still stuck to the build plate (it was printed on bare glass) and this warping did not occur. The parts were perfect before annealing but I needed the increased temperature resistance it would provide. They are quite satisfactory now; the annealing resulted in minimal deformations, but in more demanding applications there could be challenges. All in all the performance of the HTPLA itself was excellent. After printing, the parts had a matte, brass colored plastic look that was unchanged by annealing. The development of a brass-like appearance requires polishing. One must consider many choices, and the best ones are unclear. I first used 200 grit sandpaper to remove lines and the surface roughness. I followed this up by 400 and 800 grit papers. On one part I continued with 1000 grit paper followed by rough and fine plastic polishes and a coat of wax. The rougher polishes look in reflected light like finely pitted brass. The surface is smooth but the embedded brass particles are bright and provide contrast with the plastic. As the light becomes oblique and less reflection occurs the gloss of the plastic become dominant and the look is of brass colored plastic. The very polished part looks less like brass. The plastic itself is highly reflective and hides the brass particles with its surface sheen. The plastic takes a very fine polish easily and it's nice, but the look is actually less like brass than the rougher polish provided. Perhaps roughing up the surface with 800 or 1000 grit would remove this sheen and restore the sparkle of the underlying brass. The polishing procedure is easy in principle but for complex shapes and parts that cannot be disassembled after printing it's not easy or even possible. It would be interesting to explore a vibratory tumbler or perhaps a wire brush, but there's not much guidance yet on these choices from Protopasta. Anyway, this is an excellent product but there's a lot to be discovered (or at least published) about annealing HTPLA and how to develop optimal surface finishes. My 50 grams have run out so my tests are at an end until I purchase more.

Very satisfied

I'm a big fan of how this polishes. Not the same as pure metal, but then I don't expect it to be either.

Great look/feel

I am trying out some trumpet mouth pieces with this. Great feel prints fast, sands really easy and gives that nice shiny look. Be warned it is brittle. I have been tuning the slicer settings and really getting a good solid print now.

Nice texture and weight.

I bought this to try out its increased weight versus other filaments. It really does feel a lot more substantial. The only complaint is I don't think its good for high detail parts unless you have the means to do a lot of polishing to bring out the metallic look. But for many simple objects I'd highly recommend it.

Nice finish but a pain in the...

Too brittle, I didn't finish a print. The finish is nice, but it looked just like the bronze.
