Founded in 2015 and based in Houston, Texas, ZYLtech Engineering grew from a home-based parts reseller into a multi-building manufacturing operation in North Houston. Their primary focus is now mass-production filament — targeting 500 metric tons/year capacity by end of 2025 — with a ±0.02 mm tolerance spec. The catalog covers PLA, PETG, ABS, ASA, fiber-reinforced grades, and specialty variants like silk, matte, and rainbow co-extrusions. Some lines (High-Speed PLA, certain ABS and ASA grades) are manufactured in the USA; others are imported. Direct store and Amazon. OEM and custom color runs available.
