Squink - The Desktop Circuit Factory


BotFactory Printer

Squink is a personal factory creating a seamless experience that allows you to prototype faster and affordably while producing repeatable and reliable results without all the mess and complication.

It uses three interchangeable heads to get the job done, all in a one simple machine that fits on your desk. Welcome to the era of "Rapid Prototyping"!


Using inkjet technology, Squink prints conductive ink on a surface to create the traces of the circuit. You can print GERBER RS-274X files or upload PNG, JPG or BMP files. The intuitive web interface will guide you through the process letting you print complex circuits in a matter of minutes.

Conductive Glue

Avoid the need of soldering. Squink uses the soldermask file generated by your CAD tool to place dots of conductive glue in every connection point where a part is to be connected. It's a piece of cake.


Aimed at assembling SMD based circuits, Squink uses vacuum to pick components from a tray. Then it aligns them using computer vision, rotates them according to the "Centroid and Rotation" file created in your CAD tool and places them accurately.

Each component is picked from a tray, not a rail, so the setup of the machine is as simple as it gets. Up to 20 slots can be configured per job, allowing for automated assembly without the complexity of large industrial machines.
