Polymaker, a 3D printing materials company, has released its latest pellet material, PolyCore PETG-1113 Marble, a PETG pellet reinforced with 30% glass fiber. The result is a matte, white finish decorated with naturally dispersed speckles of a speckled master batch, closely resembling real marble – making it suitable for visually demanding applications, such as indoor decorations, art pieces, sculptures, and high-end custom furniture, while still offering excellent printability and mechanical properties.

Fused Granule Fabrication (FGF) is becoming increasingly popular in interior design and furniture production. However, many current materials are limited in appearance, look overly plastic, and fail to meet the market’s growing demand for diverse colors and finishes.

Additionally, the process for requesting a custom finish or blending a masterbatch on-site can be a time-consuming and costly process, further limiting the use of LFAM/FGF technology within these applications.

“During our use of PolyCore PETG-1113 Marble, we were impressed by its elegant appearance and excellent printing performance. The material’s marble-like finish not only provided us with more possibilities in design but also gave our work a convincing high-end feel and visual appeal. We look forward to exploring more applications in future projects,” said Geobuild, an adopter of the material.

In addition to its aesthetic qualities, PolyCore PETG-1113 Marble offers impressive CNC milling performance. Specifically, when machined, the printed parts minimize material buildup on cutting tools and produce a smooth, polished surface, further highlighting the marble effect.

Moreover, PolyCore PETG-1113 Marble excels in printability. It offers excellent extrusion quality, strong dimensional stability, and a broad printing window (layer time range), all of which ensure high success rates across various geometries and printing environments.

From a mechanical perspective, the 30% glass fiber reinforcement provides significant strength and toughness, along with excellent interlayer bonding, balancing both decorative appeal and functionality.
