The world of 3D printing is constantly evolving, and for those seeking high precision and detail, MSLA (Masked Stereolithography) technology stands out. The Lite3DP micro 3D printer embodies this technology in a unique, accessible format. As the first of its kind built entirely on Arduino and offered as an open-source, easy-to-assemble kit, Lite3DP is redefining the landscape of 3d Printer Supply for enthusiasts and professionals alike. This compact machine is engineered for experimentation, providing a comprehensive understanding of its operation and fitting seamlessly into any workspace.
MSLA resin 3D printing excels in producing intricate details and smooth surface finishes, surpassing the capabilities of filament-based 3D printers. By curing resin with a screen, similar to the LCD on the Lite3DP, MSLA technology achieves remarkable precision. While MSLA 3D printers are becoming more price-competitive with filament printers, many remain closed-source, limiting the accessibility that has long been a core tenet of the 3D printing movement. Lite3DP breaks this mold, offering an open platform for innovation and learning within the 3D printer supply ecosystem.

File Preparation with CHITUBOX
Preparing your 3D models for printing with Lite3DP is straightforward using the CHITUBOX utility. This software slices your 3D model into individual images for each print layer. These sliced images are then formatted by the Lite3DP Converter application to be machine-readable and uploaded to a microSD card. This streamlined workflow simplifies the digital 3D printer supply chain, from design to print preparation.
Simple Printer Setup
Setting up the Lite3DP is designed for ease of use. Once powered on and with your prepared microSD card inserted, the setup process involves just a few steps:
- Attach the magnetic printing platform.
- Prepare the printing platform with a single knob adjustment.
- Select your print file on the machine’s interface.
- Choose your printing parameters: layer resolution and exposure settings.
- Place the magnetic tray and add your chosen resin – ensuring a readily available 3D printer supply of materials.
- Start the print.
The Lite3DP simplifies the complex process of MSLA 3D printing, making it accessible for users of all skill levels. During printing, the machine projects images of each model slice onto the screen, curing the resin layer by layer to bring your design to life. For those eager to experience the Lite3DP, an online simulator is available to explore its capabilities virtually.
Platform Preparation

The printing platform preparation is a crucial step before each print. The magnetic platform automatically lowers towards the screen, and a single knob allows for easy locking and precise adjustment. This initial height setting is saved in the Arduino memory, simplifying future setups and ensuring consistent print quality, reflecting thoughtful 3D printer supply design for ease of use.
Inside the Lite3DP: Components
The Lite3DP’s design centers around an all-in-one PCB, integrating an Arduino Pro Mini, a stepper motor driver, a microSD card module, and the screen which serves dual functions for masking and parameter selection. This PCB acts as the structural core, supporting the motor and other components. The base, constructed from 2mm aluminum plates, enhances structural integrity and provides passive heat dissipation for the UV LED, eliminating the need for noisy cooling fans. This design choice results in near-silent operation, with only the soft intermittent sounds of the stepper motor, activated briefly at the end of each layer. The thoughtful component selection within the 3D printer supply chain ensures both performance and ease of assembly.
Like other MSLA 3D printers, the Lite3DP features a single axis of movement, driven by a stepper motor with metal gear reduction, a precision linear guide, a square thread screw, and a POM nut. The kit includes an injected-molded plastic tray, engineered to prevent breakage and leakage. These trays will also be available separately, catering to users who require additional trays or are building their own machines, ensuring a readily available 3D printer supply for repairs or custom builds.
