The Lite3DP Gen 2 3D Printer builds on the success of its predecessor. With a new and improved design, an ESP32 microcontroller replacing the Arduino Pro Mini, and several other improvements, the Lite3DP Gen 2 is well-suited for making small, detailed resin prints.
It is slightly bulkier than the Lite 3DP S1 3D printer but is still compact enough to fit into a bag. Gen 2 has been designed to maintain backward compatibility with the older model, and owners of existing Lite3DP printers can use the Gen 2 dev kit to upgrade their printers.
The resin 3D printer is completely open-source (firmware, hardware, and software), and you can use the schematics, Gerber files, code, and other resources hosted in the GitHub repository to build a different kind of mSLA resin printer.
Lite3DP Gen 2 key features & specifications:
- Electronics – All-in-one PCB with ESP32 microcontroller, high-res LCD, an ultra-silent TMC2209 driver for the Nema 8 stepper motor, and other components

- Build volume (W x L x H) – 36.7 x 48.8 x 80 mm
- Tray volume – 50 cm³ for the liquid resin
- Compatible resins – All UV 405 nm resins (standard, industrial, flexible, castable, dental, etc.)
- Print speed – up to 40 mm/h
- Data input – micro SD card autonomous operation
- Misc – Buttons, capacitive touch buttons, passive heat dissipation, touchscreen
- Power Supply – 12 V, 5.5×2.1 mm, ≥1 A)
- Power consumption – less than 10 W
- Dimensions – 100 x 100 x 167 mm
- Weight – 470 grams (16.6 oz.)
The Gen 2 resin 3D printer doesn’t have the prettiest specifications and feature list. Still, its open-source nature means it is going to be easier to repair, maintain, and customize than the commercial options in the market. It is also cheaper than the alternatives, at $229 for the pre-assembled product and only $115 for the dev kit. That excludes the shipping fee, $8 to the United States and $18 to the rest of the world.
Lite3DP Gen 2 launched on Crowd Supply last November and funding will end on Dec 21. If you are interested in this mini, open-source resin 3D printer, you can place an order on Crowd Supply for either the full printer or the dev kit.
