At B-A-R printing we love to print new designs and test new filaments every day. We are a small business just trying to get started, but I do have experience printing with tough filaments such as nylon and reinforced nylon with glass and carbon fiber. We also print using TPU and your typical pla and pla+ filaments. If given the file there is nothing we couldn’t get printed no matter the filament. We are also a licensed 07 FFL and will print objects in that category as well!
