Mystery Color are filaments color that didn't turn out exactly as anticipated, typically due to the transition between different colors in our filament extrusion process. The filament remains perfectly usable for printing, made with 100% Grade A Virgin PCTG.

Filaments Depot PCTG

PCTG (Poly-Cyclohexylenedimethylene Terephthalate Glycol) is a durable and versatile 3D printing filament known for its superior impact resistance, clarity, and chemical resistance. As part of the same material family as PETG, PCTG offers enhanced toughness and thermal stability, making it an ideal choice for both functional and aesthetic prints.

Key Features:

  • Superior Impact Resistance: PCTG offers up to 20 times higher impact resistance than standard PETG, making it ideal for applications requiring durability.
  • Excellent Clarity: Provides a clear, glass-like finish, perfect for creating transparent or translucent prints.
  • Higher Heat Resistance: With improved thermal stability, PCTG can withstand higher temperatures without deforming compared to PETG.
  • Enhanced Chemical Resistance: Offers superior resistance to chemicals, oils, and cleaning agents.
  • Ease of Printing: Prints at similar settings to PETG with minimal warping and excellent layer adhesion.
  • Eco-Friendly: PCTG is 100% recyclable, aligning with sustainable practices.

Applications:

  • Functional Prototypes: Ideal for mechanical parts, casings, and tools requiring impact resistance.
  • Protective Equipment: Suitable for creating face shields, guards, and covers.
  • Transparent Models: Great for producing clear parts like bottles, containers, and display models.
  • Consumer Products: Perfect for durable items such as phone holders, kitchen tools, and protective cases.

PCTG vs. PETG - Key Differences:

Feature PCTG PETG
Impact Resistance ⭐⭐⭐⭐⭐ (Superior) ⭐⭐⭐ (Good)
Heat Resistance ⭐⭐⭐⭐ (Higher) ⭐⭐⭐ (Moderate)
Clarity ⭐⭐⭐⭐ (Excellent) ⭐⭐⭐⭐ (Excellent)
Chemical Resistance ⭐⭐⭐⭐ (Enhanced) ⭐⭐⭐ (Standard)
Ease of Printing ⭐⭐⭐⭐ (Minimal warping) ⭐⭐⭐⭐ (Minimal warping)

 

Why Choose PCTG Over PETG?
If you require a stronger, more impact-resistant material with improved heat resistance, PCTG is the superior choice. Its durability makes it ideal for demanding applications while still being easy to print with standard PETG settings.
