Protopasta filament prints consistently clean no matter how many spools I go through. Great quality product!

Favorite red colored filament!

I can't believe this silver isn't metal

Candle light is incredible!

Comparable to the NES Legends of Zelda cartridge

I love the weird filaments they send. I haven’t been disappointed yet!

Great fun for anyone who likes to experiment. This latest batch is some of the best glow-in-the-dark filament I’ve ever seen.

Worked as well or better than regular PLA, highly recommended if you could use this as a problem solver.

The filament is beautiful and arrived quickly and in tact.

Soi far I have been using Proto-Pasta, steel, Iron amd Brass composite Metal on my H2D , I run it from the External connection and run from a Creality Space Pi Filament Dryer to keep humidity down.. now I keep the temp on the plate a bit higher 65/70 and the Proto at 195 and got excellent results.

Works great! Especially with the new plastic reel. The carton reel normally arrives with some damage, crushed,cwhich creates a problem in the AMS.

Excellent material, printed perfectly using Bambulabs a1 mini following the specs for the filament.
