Hello everyone. I am new to 3D printing well my son is. He is 11 years old and very knowledgeable of computers etc. I am his mom and know nothing. We just got him a printer for Christmas and he is printing a lot of stuff and it's amazing!! He wanted to try to use TPU Filament and he is having a problem with it. We sure could use some help with this! Thank you for any help we do get!!
