PCTPE is a newly developed highly flexible 3D Printing material. PCTPE stands for "Plasticized Copolyamide TPE" or a chemical co-polymer of highly flexible nylon and TPE (thermoplastic elastomer) . PCTPE has several unique features that allow any user to print a highly flexible part with the added durability of nylon polymers. This combination of polymers was developed specifically to allow anyone using current FFF 3D Printers to print parts from durable prosthetics to complete cosplay wearable outfits, cell phone enclosures as well as highly flexible utility/industrial parts. The flexibility of PCTPE means that the end parts will have the smooth lustrous texture of nylon, the added flexibility offered by a rubber like TPE, yet maintain the high durability and non-delaminating benefits of all taulman3D Printing materials. Like all taulman3D Nylon materials, PCTPE takes on acid based dyes for any color desired. It's stock color is a bright gloss white. A major feature of PCTPE is it's high flexibility, it will not fold, bend or dislodge in the extrusion path of 3D Printers, a common issue with other flexible materials.
