In today’s video, I’m testing 3D-Fuel’s Pro PCTG vs their Pro PETG to find out which one actually makes stronger 3D-printed parts.
Both of these materials are copolyesters in the PET family, but they behave very differently once you print them — and even more differently when you break them.
As always, this is real mechanical testing using my standardized TLAR methods:
✔ X-Axis Tensile Tests
✔ Layer Adhesion Break Tests
✔ Direct Thread Strength
✔ Heat-Set Insert Pull Tests
✔ Izod Impact Tests
The results?
PETG wins raw tensile strength, but PCTG absolutely crushes it in layer adhesion, ductility, real-world load survival, and overall functional performance. For most actual printed parts, PCTG produces dramatically stronger and more reliable prints.
This video is not sponsored, the materials were supplied by the manufacturer with no expectations.
As always, the data speaks for itself.
