Spectrum PCTG filaments represent an advanced technical material designed for users who need a combination of strength, toughness, and easy printability.
PCTG filament (PolyCyclohexylenedimethylene Terephthalate Glycol) belongs to the same family as PETG filament, but thanks to its chemical structure, it offers significantly better mechanical properties, higher impact resistance, and stability during printing.




Spectrum PCTG combines properties that make it an ideal replacement for PETG in cases where higher strength and temperature resistance are required.
Prints made from this material are tough, flexible, and resistant to impacts and heat (up to 90 °C). Thanks to its chemical stability, the material retains its shape even under long-term load, while remaining very easy to print even without an enclosed print chamber.Characteristic properties of Spectrum PCTG:
Up to 30% higher impact resistance than PETG
Heat resistance up to 90 °C
Excellent layer adhesion and minimal warping
Dimensional accuracy and a smooth, glossy surface
Odorless and emission-free – safe even for home use
High chemical resistance to oils, lubricants, and alcohols
Crystal clarity – ideal for transparent or semi-transparent prints
Spectrum PCTG filaments are used in the production of functional prototypes, enclosures, fasteners, holders, mechanical parts, and design models, where impact resistance and long service life are required.
The material retains its strength and flexibility even after prolonged use, making it suitable for technical applications, packaging systems, or transparent device covers.Recommended print parameters:
Nozzle temperature: 250–270 °C
Bed temperature: 75–90 °C
Print speed: 40–60 mm/s
Fan: 50–100% (depending on the type of print)
Printing with PCTG Spectrum is stable, without the need to use adhesion agents or special settings, making it a user-friendly technical material.
Like other products from Spectrum Filaments, the PCTG range is also available in many color variants – from clear and transparent to rich, technical shades. The material is precisely wound onto a spool, vacuum-sealed and protected from moisture to preserve maximum quality and consistent printing results.
Spectrum also offers eco-friendly Refill versions without a plastic spool, which enable waste reduction and more environmentally friendly 3D printing without compromising on quality.
Higher mechanical resistance and toughness
Better temperature stability
Lower tendency to string during printing
Cleaner, smoother print surface
Longer lifespan and higher impact resistance
If you are looking for a material that prints as easily as PETG, but offers higher performance, strength, and reliability, then Spectrum PCTG is the ideal choice. Thanks to its balanced composition, it delivers professional results without complicated printer setup.
The Spectrum PCTG Filaments category offers a modern, durable, and precise material designed for demanding users who want to achieve the perfect balance between ease of printing, strength, and print aesthetics. A perfect choice for technical, functional, and visually appealing projects.
