Fusion3 is a Greensboro, North Carolina company which manufactures 3D printers for commercial and education use.

[1] Fusion3 was started by North Carolina State University Alumna Katelyn Padgett who after building several kit 3D printers, developed a proprietary linear motion process to improve upon the existing, open source 3D printer designs.

The company received a $25,000 grant from the Innovation Fund of North Carolina in 2014 to invest into patent activities and for marketing purposes.

EDGE featured both the company's new ANVIL tube print head system, a new bed leveling system, and precision linear rails maintaining the company's fast speeds, but also improving print quality.

Available as either a single extruder (F400-S) or what it calls the 'high flow rate' (F400-HFR), the F400 is based the same Core XY framework (F-Series Platform) as its predecessor, the F306.
