PCTPE, or Plasticized Copolyamide TPE, is a highly flexible nylon that is designed to print easily from commercial 3D printers. As an elastomer, PCTPE behaves like a rubber and is useful in flexible applications. PCTPE also remains durable as a nylon, allowing it to withstand wear. This makes PCTPE ideal in shock absorbing applications like phone cases. Its smooth texture also makes it comfortable to the skin, which makes it a great choice for wearable prints. If you need a highly flexible material that is durable and wearable, PCTPE is a great choice.
