What is a PCTG material

AN ALTERNATIVE TO PET-G

The PCTG belongs to the same polyester family as the increasingly popular PET-G. Compared to its better known counterpart, PCTG offers higher impact strength, temperature resistance and clarity of what it is about an excellent alternative to PET-G makes. This filament does not require a heated chamber, which means it can be used in home printers. At the same time, it offers high dimensional stability and the low shrinkage prevents model breaks. That makes it a print-friendly material, even for people with little experience in 3D printing.

The PCTG has a much higher impact resistance compared to similar materials (like PET-G). In the Izod test (notched sample) it achieves results of approx. 90 kJ / m2 (PET-G: 5-8 kJ / m2). The PCTG can also withstand higher temperatures (up to 76 ° C).

The Fiberlogy PCTG is recyclable and approved for contact with food *. The material is BPA-free.
* applies to the Pure TR variant

APPLICATION OF 3D PRINTING:

  • INDUSTRY: Spare parts, small series, utility models
  • AUTOMOTIVE: Engine compartment components, housings of vehicle components, air inlets, filling devices for liquids
  • SPORTS: Accessories, protectors, airsoft components

Properties:

  • high impact strength (up to 20 times higher than PET-G)
  • high chemical resistance
  • high optical clarity
  • easy printing - dimensional stability and low shrinkage
  • suitable for contact with food - BPA-free

How to print it

The following parameters are only recommended print settings for this material. To ensure the best print quality, the appropriate settings must be selected for a particular printer and printing conditions.

 

Printing temperature250-270 ° C
Heating bed temperature90-110 ° C
Closed chambernot mandatory
Fan25-50%
Flow rate90-100%
Print speed<100 mm / s
surfaceMasking tape, PVA glue, hairspray
Retraction (direct)1-2 mm
Retraction (bowden)4-6 mm
Retraction speed10-30 mm / s
Drying conditions60 ° C / 4h
DangerDue to the strong adhesion, it is not recommended to print directly on the surface of the table or glass as it can cause damage. We recommend using tape.
