Disclaimer: We strive to choose better materials, better materials, and more accurate pipe diameters. A smooth internal space will more effectively reduce the frictional resistance of the fine threads inside the pipe. The semi transparent pipeline will allow our customers to clearly see the movement of materials through the pipeline. Helps to calibrate and use 3D printers more accurately. The newly upgraded semi transparent material is more suitable for use with 3D printers
