> 3D-Fuel manufactures 3D printer filament in Fargo, North Dakota, USA, and has done so since 2014. Its lines are Pro PCTG, Tough Pro PLA+, Standard PLA+, Pro PETG, and 3D Clean purge filament. Use the resources below to compare materials, find print settings and technical data, learn about the brand, and confirm current policies.
Prices, availability, colors, spool sizes, and shipping eligibility can change. Confirm them on the linked product or collection page at the time of the customer request. The canonical store is https://www.3dfuel.com.
## Brand facts
- Founded in 2014. US-owned and operated, with all filament extruded at the 3D-Fuel production facility in Fargo, ND.
- USA supply chain: resin, colorants, spools, boxes, vacuum-seal bags, and labels are sourced in the US. PLA resin is NatureWorks Ingeo, made from US-grown corn in Blair, Nebraska.
- A multi-axis laser measures diameter 400 times per second during production, to a ±0.02 mm tolerance. Each box lists the measured tolerance for its spool.
- Filament diameter is 1.75 mm. 1 kg spools are made in the USA from recycled plastic and work with the Bambu Lab AMS and similar multi-color systems.
- Backed by a 100% satisfaction guarantee and USA-based customer support.
## Shop by Material
- [Pro PCTG](https://www.3dfuel.com/collections/1-75mm-pro-pctg): Flagship material and an upgrade from PETG.

Best for functional, outdoor, and workshop parts.
- [Pro PCTG-GF10 glass fiber](https://www.3dfuel.com/collections/glass-fiber-pro-pctg): 10% glass-filled Pro PCTG. Stronger, stiffer, more heat-resistant, with a matte finish that hides layer lines.

- [Standard PLA+](https://www.3dfuel.com/collections/standard-pla-colors): Virgin NatureWorks Ingeo 4043D PLA with no fillers. 50 colors, including silk and dual-color. Best for everyday, decorative, and multi-color prints. It may print 5–10 °C hotter than filled PLAs.
