Poly Cyclohexylenedimethylene Terephthalate glycol-modified is a member of the large family of plastics, the polyesters. PCTG is very similar to another member of the polyester family, the more commonly produced PETG.

PCTG and PETG have a very similar molecular structure and display similar properties however PCTG has much better chemical resistance as well as being slightly more durable and having a broader range of printing temperatures.

PCTG has a printing range of 210°C to 260°C. Printing at the lower end of this spectrum will give a matt finish whilst printing at the higher end will give a glossy finish. PCTG tends to have a glass transition temperature of around 84°C. These figures can vary from filament to filament so always check the Technical Data Sheet. PCTG is relatively low warp, an enclosure should not be necessary but a heated bed of around 60°C may help adhesion. PCTG requires a print speed between 30mm/second and 70mm/second; as with all filaments, higher print speeds will require a higher extrusion temperature.

PCTG is a relatively low cost, high performance filament that is an excellent alternative to PETG if your final product requires increased chemical resistance. Here at you can select the right PCTG filament using our constantly updated list of suppliers and our comprehensive search tool!
