Technology & Products
Key Products
Cohesion3D LaserBoard; Cohesion3D Mini Motion Controller; Cohesion3D Rotary Attachment; ReMix control board; Peripherals and optics
Technological Advantage
Proprietary firmware integration and hardware design optimized for motion control in additive manufacturing and laser cutting, offering a cost-effective alternative to premium controllers like Ruida.
Differentiation
Value Proposition
Provides affordable, high-performance control boards that liberate laser cutters and 3D printers from stock limitations, enabling better software compatibility, variable power for grayscale engraving, and expanded capabilities like rotary attachments, reducing upgrade costs and improving user experience.
How They Differentiate
Compared to Moshi and Gerbil boards, Cohesion3D offers better performance and configurability for K40 upgrades; versus Ruida, it provides a more affordable G-code-based solution with Smoothie firmware compatibility, though with fewer premium features.
