Lite3DP 3D Printer

An Arduino-based, open source MSLA / LCD-SLA resin micro 3D printer kit

This project is coming soon. Sign up to receive updates and be notified when this project launches.


Lite3DP S1 is a resin micro 3D printer with MSLA technology, the first of its kind based entirely on an Arduino board. It will be provided in a complete and easy-to-assemble kit format, offering an enriching and educative experience for its users.

The Lite3DP is a 3D printer that stands out for its simplicity, absence of noise, and being small, lightweight, and low cost. With the RepRap project as inspiration, it seeks to set a milestone within resin 3D printing: popularize simple and inexpensive machines, allowing more people to get closer to 3D printing.

Lite3DP S1 allows the manufacture of plastic parts by solidification, layer-by-layer, of a liquid photosensitive resin. Its 3D prints achieve an extraordinary detail level and surface finish, far superior to what filament 3D printers can reach. It works with any brand of 405 nm UV resins, it has a precision linear guide, works autonomously with a microSD card, and the tray and platform have a magnetic attachment system (a single manual knob for its preparation).
