Indoor Decoration - Polymaker

The last couple of months have been a quiet riot of activity for PolyCore – not in theory, but in tons of real, tangible objects that landed in design districts, metro stations, construction sites, and even Antarctic test rigs. We thought you’d like a quick look at what’s happened, because chances are one of these materials is exactly what you’ve been searching for.

Three personalities, one week in Milan

Milan Design Week turned into a PolyCore showcase without anyone planning it that way. Three projects, three grades, three completely different demands:

Royals collection by IAMMI Studio - delicate, jewelry-like lampshades printed in PolyCore™ PETG-1000. The translucent finish makes light the narrator; if your project lives or dies by clarity and controlled diffusion, 1000 is the grade that delivers.
Lithic Flow Divider by Caracol AM, a parametric architectural wall with an authentic marble finish, straight out of the extruder. The secret is PolyCore™ PETG-1113 Marble, which gives you genuine stone aesthetics without compromising the structural performance and printability of glass-filled PETG. No post-finish tricks — the marble is in the material itself.
Ginger Pavilion nodes by Sina Lüder, reusable, material-efficient connectors printed in PolyCore™ PETG-1312. These nodes form a fully functional structure, proving that medium-format LFAM can deliver the detail, strength, and dimensional stability that real construction demands.

Architectural-scale statements, Suzhou and Shanghai

On the other side of the globe, two landmark projects were redefining what’s possible with pellet extrusion at building scale.

Sérac 凌川 indoor partition by Dr. Dasong Wang - now standing permanently in our Suzhou R&D center- is a masterclass in material pairing. The load-bearing base uses PolyCore™ PETG-1113 (30% glass fiber) for rigid folded strength, while the upper translucent volume exploits the high transmittance of PolyCore™ PETG-1000 to turn glacier-like topology into light-filled space. Two materials, one seamless experience.
Origin of Huangpu magnolia sculpture by Flash - blooming inside Shanghai’s busiest metro station, this public artwork was fabricated with PolyCore™ PETG-1312. For medium-format projects where complexity, scale, and deadline collide, PETG-1312 is formulated to remove the usual trade-offs: clean retraction, dramatically reduced warping, and a surface finish that cuts post-processing down to size.

And then there’s the rover tire bound for Antarctica

In Eindhoven, Team Polar, TU/e, and Holit turned PolyCore™ TPU-2000 into the first 3D-printed tire for the Gentoo rover. UV-stable, exceptionally durable, and flexible enough for extreme cold, this TPU grade was built for demands that don’t accept compromise- no design fair, no gallery lighting, just relentless performance where it counts.

So, which PolyCore has your name on it?

Maybe you need the glass-clear depth of PETG‑1000. Maybe the stone elegance of 1113 Marble has been the missing ingredient. Maybe your project demands the medium-format precision of PETG‑1312, the heavy‑duty strength of PETG‑1113, or the industrial resilience of TPU‑2000.

They’re all out in the world, working hard, right now.

From Bottle to Breakthrough

PolyCore™ PETG-1000 R85 — 85% PCR Pellets for Sustainable LFAM

Plastic bottles drifting in the ocean, packaging buried in landfills, containers tossed on the streets - these are the consequences of nearly 400 million tons of plastics produced every year, almost half of which are single-use[1]. The call to reduce the use of virgin plastics and embrace circular solutions has never been louder.

Polymaker’s PolyCore™ PETG-1000 R85 answers this call. Made with 85% post-consumer recycled (PCR) content, this pellet-based material turns discarded plastics into premium feedstock for LFAM/FGF. It delivers a practical path to circular manufacturing—combining reliability in printing with a unique visual character.

What is PCR?

Post-Consumer Recycled (PCR) plastics come from everyday items that have already been used — such as beverage bottles, food packaging, and household containers. Once collected, cleaned, and reprocessed, they are transformed into high-quality raw materials — turning waste into resources and reducing dependence on virgin plastics.

Bottles Reborn, Carbon Reduced

PolyCore™ PETG 1000 R85 is formulated with 85% PCR content from single-use, consumer PET beverage bottles sourced from municipality waste. By using advanced chemical recycling, the bottles are broken down and rebuilt into consistent, high-performance 3D printing pellets.

What does this mean for the environment?

A typical 500 ml PET bottle weighs about 20–25 g, so each kilogram of PETG-1000 R85 brings approximately 40 single use plastics bottles back into circulation and out of the landfill

The material is also certified under the Global Recycled Standard (GRS) — the leading international benchmark for recycled content, traceability, and responsible production. Since 2008, GRS has set the global framework for credible sustainability claims. For PETG-1000 R85, this means every stage—from sourcing recycled raw materials to final manufacturing—meets strict standards for transparency, environmental performance, and social responsibility.

Reliable Printing × Expressive Design

In practice, PETG-1000 R85 offers smooth extrusion and consistent melt flow, making is suitable for a variety of pellet printer sizes and screw types / dimensions.

Beyond performance, the material’s semi-transparent pale green hue shifts naturally with varying thicknesses flowing from airy translucence to rich, vibrant tones. This dynamic character makes it especially powerful in artistic and architectural applications: the fluid curves of custom furniture, the shifting glow of façades, or the layered translucency of installations all gain a sense of vitality and movement through this material.

July 2025 — Polymaker, a global innovator in 3D printing materials, proudly announces its latest pellet material, PolyCore™ PETG-1113 Marble. This material artfully combines a marble-effect masterbatch with PolyCore™ PETG-1113, a PETG pellet reinforced with 30% glass fiber. The result is a stunning matte, white finish decorated with naturally dispersed with a speckled master batch, closely resembling real marble. This unique aesthetic makes PolyCore™ PETG-1113 Marble an ideal choice 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), also known as Large-Format Additive Manufacturing (LFAM), 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 timely and costly process, further limiting the use of LFAM/FGF technology within these applications.

To address this challenge, Polymaker has developed PolyCore™ PETG-1113 Marble. A pellet delivering a marble-like texture straight out of the extruder with no post-processing required and achieving both visually and tactilely appealing results.

(Designed by Geobuild)

Feature above is the ‘Fuyao Chair’ designed and printed by Geobuild, a 3D printing company specializing in architecture and design. After successfully printing using PolyCore™ PETG-1113 Marble, it gained significant attention at the TCT Asia 2025.

Geobuild stated, "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."

In addition to its aesthetic qualities, PolyCore™ PETG-1113 Marble offers impressive CNC milling performance. Specifically, when machined, the printed parts minimizes material buildup on cutting tools and produces a smooth, polished surface, further highlighting the marble effect. This finishing option allows users to further enhance the marble-like appearance of their designs.

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.
