Spectrum PET-G / PTFE Schwarz 1.75mm 1kg (RAL 9017)

PETG with tribological properties

The popularisation of 3D technology and the increase in specific expectations regarding the functionality of prints brings the need to develop increasingly specialised materials. Analysing the needs of the market and repeated requests from customers, we decided to supplement our range with PETG material with tribological properties.

We present Spectrum PETG/PTFE copolymer for use in sliding elements and gears. As the basis for the material, we used PETG, well-known for its excellent mechanical properties, supplemented by adding 10% PTFE, commonly known as Teflon, with self-lubricating properties. Thanks to the meticulous selection of components while reducing the coefficient of friction, the filament retains the ease of printing, interlayer adhesion, impact strength and thermal properties typical of PETG.

Spectrum PETG/PTFE will find use in printed components subject to increased wear from friction and operating temperatures of up to 70°C. The filament is available in a wide range of colours.

Key features

• 10% PTFE content
• reduced coefficient of friction in comparison to conventional PETG
• thermal resistance up to 70°C
• ease of printing
• good chemical resistance
• perfect bonding of the layers

Applications

• functional prototypes,
• manufacturing low friction parts
• manufacturing low-load gears and transmission elements
• end-use parts

Colors

• black (RAL 9017),
• blue (RAL 5012),
• grey (RAL 7005),
• red (RAL 3028),
• white (RAL 9003)

Packaging
Filament is reeled on the neat, transparent spool. Each spool contains information on the type of material, diameter and recommended printing temperature. Filament is vacuum-packed with a moisture absorber. Whole product packed in the original, folied Spectrum Filaments packaging.

VERIFY YOUR SPOOL – the most precise quality control system on  the market
Filament for 3D printers is manufactured by the method of free extrusion, which is one of the most difficult processing techniques by extrusion, due to the particularly significant impact of process parameters on product dimensions and material homogenization.

During the production each 1mm of Spectrum Filament is being continuously measured in 2 axes with ±0.8µm accuracy, which allow obtaining a high-quality final product. To prove this, Spectrum Filaments, as one of the few manufacturers in the world, has introduced the possibility of online presentation, individually for each manufactured spool:

• the course of diameter on the entire length of the spool,
• mean diameter,
• ovality,
• standard deviation.

Precise survey guarantees that Spectrum Filaments products meet rigorous market requirements.
