lite3dp gen 2 resin printer

Lite3DP Gen 2 is a tiny open source 3D resin printer (crowdfunded)

The Lite3DP Gen 2 3D printer builds on the success of its predecessor. With a new and improved design, an ESP32 microcontroller that replaces the Arduino Pro Mini, and several other improvements, the Lite3DP Gen 2 is well suited for producing small, detailed resin prints.

It’s slightly bulkier than the Lite 3DP S1 3D printer, but still compact enough to fit in a bag. Gen 2 is designed to maintain backwards compatibility with the older model, and owners of existing Lite3DP printers can use the Gen 2 development 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 create another type of mSLA resin printer build.

Key Features and Specifications of Lite3DP Gen 2:

  • Electronics – All-in-one board with ESP32 microcontroller, high-resolution LCD, an ultra-quiet TMC2209 driver for the Nema 8 stepper motor and other components
  • Firmware: Arduino
  • Technology – MSLA // LCD SLA
  • Resolution – XY: 0.115mm; Z: 0.025, 0.05 and 0.1mm
  • Construction volume (W x L x H) – 36.7 x 48.8 x 80 mm
  • Container volume – 50 cm³ for the liquid resin
  • Compatible Resins – All UV-405nm resins (standard, industrial, flexible, castable, dental, etc.)
  • Print speed – up to 40mm/h
  • Data entry – autonomous operation with micro SD card
  • Other – Buttons, capacitive touch buttons, passive heat dissipation, touch screen
  • Power supply – 12V, 5.5×2.1mm, ≥1A)
  • Power consumption – less than 10W
  • Dimensions – 100 x 100 x 167mm
  • Weight – 470 grams (16.6 ounces)

The 2nd generation resin 3D printer doesn’t have the nicest specs and feature lists. Still, its open-source nature means it’s easier to repair, maintain and customize than the commercial options on the market. It’s also cheaper than the alternatives: $229 for the pre-assembled product and just $115 for the development kit. This does not include shipping costs, which are $8 to the USA and $18 to the rest of the world.
