Early Bird Price: 5,888 RMB – The Compact Submersible SLA Laser 3D Printer – MINI by Miracle Smart

Panda3dp.com Guide: LCD 3D printers, based on the top-down photopolymerization principle, have dominated the consumer resin printing market since their inception due to their relatively low cost, with annual global shipments reaching hundreds of thousands of units. In contrast, submersible SLA laser 3D printers offer superior stability and success rates but have traditionally been limited to industrial applications due to their higher pricing.

Previously, Panda3dp.com reported on the SLA150, a desktop-sized submersible 3D printer introduced by Jiangsu Miracle Smart. Since its launch, this device has garnered significant attention for its outstanding performance and competitive pricing.

On March 11, 2025, Panda3dp.com learned that Miracle Smart has unveiled an even more compact model—the 50BOX. This new submersible SLA printer maintains the same advanced technology while being priced competitively with LCD resin printers on the market. With a standard price of 6,888 RMB and a limited-time early bird price of 5,888 RMB, it presents an attractive option for budget-conscious users seeking high-quality 3D printing.

Innovative Structural Design – A Super-Compact Submersible SLA Laser 3D Printer  

The engineering team at Miracle Smart has reimagined and refined the design of the 50BOX, resulting in an innovative, ultra-compact form. The printer boasts a cubic build volume of 50 × 50 × 50 mm, catering to applications such as small component manufacturing, figurines, material research, and educational training. The overall machine dimensions measure less than 20 × 20 × 40 cm—roughly the footprint of a smartphone, with a height equivalent to two stacked phones. Weighing a mere five to six kilograms, it is effortlessly portable, allowing users to reposition it at will, making it a truly mobile and flexible SLA 3D printer.

Minimal Startup Resin Requirement – Only 100ml Needed to Begin Printing  

For users working with experimental resins, where high material costs or incomplete formulations limit available testing quantities, the 50BOX offers multiple interchangeable resin vats. These vats can be swapped without requiring any screws to be removed, facilitating seamless transitions between different material testing phases. Notably, the smallest vat requires just 100ml of resin to initiate printing, significantly reducing waste and cost.

△ You can start printing with just one cup of consumables.

Vacuum Coating Blade – Handling High-Viscosity Resins with Ease  

Despite its compact size, the 50BOX employs the same submersible SLA printing principles as larger industrial-grade machines. Unlike LCD printers, it eliminates the need for release films and avoids peeling forces during detachment, thereby enhancing print success rates. Additionally, the adjustable vacuum coating blade ensures precise and uniform resin application, allowing it to handle high-viscosity and low-fluidity resins—materials that standard LCD printers struggle with—guaranteeing superior print accuracy and success rates.

Industrial-Grade Laser Modules – Customizable Power for Specialized Materials  

To accommodate diverse material curing requirements, Miracle Smart has developed a series of laser modules with adjustable power outputs ranging from 100mW to 2000mW. Unlike broad-spectrum light sources, the point-focused laser irradiation system delivers an energy density dozens to hundreds of times higher than traditional light sources, ensuring comprehensive polymerization reactions and tighter layer adhesion along the Z-axis. This advanced laser system enables the 50BOX to print not only standard resins but also high-wax castable resins, silicon nitride, and silicon carbide ceramic slurries, which are notoriously difficult to process using conventional methods.

Ultra-Fine Laser Spot – Bridging the Gap Between Micro-Nano and Conventional Resin Printing  

Equipped with a high-precision industrial laser module, the 50BOX achieves an ultra-fine laser spot diameter of just 40μm (0.04mm). Combined with Miracle Smart’s proprietary scanning trajectory algorithms and dimensional interpolation techniques, it can accurately print intricate structures ranging from 0.1mm to 0.5mm. This feature makes it an ideal cost-effective alternative to high-end micro-nano printing devices, bridging the gap between expensive professional equipment and standard consumer resin printers.

Fully Open Parameter Control – Tailor Printing to Your Needs  

Beyond its hardware innovations, Miracle Smart has independently developed a comprehensive control software suite, granting users full access to all critical process parameters. Users can fine-tune laser power, scanning trajectories, scanning speed, and laser compensation settings, among dozens of other adjustable parameters, enabling highly customized print configurations. The software also supports layered slicing and one-click printing, ensuring seamless adaptability to various resins and operational conditions.

All-in-One Design – Ready to Print Straight Out of the Box  

For maximum convenience and ease of use, the 50BOX follows a streamlined, all-in-one design philosophy. With a compact, well-integrated structure, every unit undergoes rigorous calibration before shipment, ensuring users can start printing immediately upon unboxing—just add resin and begin your 3D printing journey.

The 2025 TCT Asia Exhibition will take place from March 17-19 at the National Exhibition and Convention Center (Shanghai), Halls 7.1 & 8.1.
