PCTPE is another amazing material by taulman which provides the flexibility of an elastomer with the durability of nylon. PCTPE stands for “Plasticized Copolyamide TPE” or a chemical co-polymer of highly flexible nylon and TPE (thermoplastic elastomer). The interlayer adhesion of PCTPE is excellent which is what makes this elastomer the most durable of any we have tested to date.

PCTPE is a tricky material to keep stuck to the build plate, and since it has such high layer adhesion, it is also difficult to remove brim and support material.

Aside from the slight difficulties to print, this material is our favorite elastomer for any industrial application. This is perfect for high impact parts under significant loads as well as vibration dampening applications.  PCTPE comes in clear and can be dyed to specific color requirements in post process.

Pros:

• Very flexible

• Very high layer adhesion

• Great elastomer for any industrial application

Cons:

• Difficult to remove brim and parent support material

• Difficult to stick to the build plate

• Requires slow printing

• Requires post processing to achieve color
