EST. 2018 · CHANGSHU, SUZHOU, JIANGSU
Obsessive about color. Honest about everything else.
A materials company from Changshu that put its own name on the spool.
THE STORY
From trading floor to color lab.
01
2018 · Founded in Changshu
CHCKX started in 2018 as a new-materials company in Changshu, Suzhou: a city that lives and breathes polymers. Before a single spool existed, the business was materials, suppliers, and specifications.
02
The trading years
Years of materials trading taught one lesson that still runs the company: color sells, documentation keeps. A striking spool wins the first order; a straight answer about tolerance and drying wins the tenth.
03
Late 2025 · CHCKX lands on Amazon US
The CHCKX filament line launched on Amazon US, fulfilled by FBA and built color-first: proprietary color formulas engineered for vivid, fade-resistant prints, dried 24 hours and vacuum-sealed before they ship.
04
2026 · Six chemistries, one shelf
The range now spans six chemistries and 91 colorways, from everyday PLA to community-tested PCTG and fiber-filled engineering lines. Every line gets the same treatment: a spec table, marked representative values, and a TDS on request.
DUE DILIGENCE
What we are. What we are not.
What we are
- A 3D-printing materials company based in Changshu, Suzhou, Jiangsu.
- The maker of proprietary color formulas engineered for vivid, fade-resistant prints.
- A QC gate: every spool is dried 24 hours, vacuum-sealed with desiccant, mechanically wound and inspected.
- An Amazon US seller you can check yourself. The storefront is linked right below.
What we are not
- A factory. We work with specialist extrusion partners in Jiangsu and put our name on the QC.
- A wall of certification badges. We claim none.
- A review-count billboard. The storefront speaks for itself; we quote no invented numbers.
