2 Best SLA Printers 2025 in the United States

The Phrozen Sonic Mighty 8K LCD Resin 3D Printer stands out with its impressive 8K resolution, ensuring that even larger prints retain exceptionally sharp details. This makes it highly suitable for users who need high-resolution prints, such as designers and architects. Its substantial build volume of L21.8 x W12.3 x H23.5 cm allows for the creation of larger models or multiple smaller models simultaneously, enhancing productivity.

The laser power and resin compatibility are robust, supporting various resin types which provide flexibility for different printing projects. Print speed is efficient, further boosted by the 10” monochrome LCD screen that has a longer lifespan, which means more consistent performance over time. The dual linear rails and frosted laser cut building plate reduce wobbling and enhance the success rate of prints, giving users more reliable output and less frustration from failed prints.

Ease of use is underscored by the Phrozen GO app, which enables remote control of the printer, although limited to one account per printer which might be a drawback for collaborative environments. However, the printer does require post-processing, which is typical for resin prints but adds an extra step for users. Despite its powerful capabilities, it maintains a compact footprint, making it suitable for various workspaces. The Phrozen Sonic Mighty 8K is a strong contender in the SLA printer category, particularly for users who prioritize high resolution, reliability, and flexibility in resin compatibility, though they should be prepared for the necessary post-processing steps.

The Phrozen Sonic Mini 8K S LCD Resin 3D Printer stands out for its exceptionally high print resolution of 22 µm, which ensures that the printed models are precise and detailed, making it ideal for intricate designs. With a build volume of L16.5 x W7.2 x H17 cm, it is suitable for small to medium-sized projects. The 7.1” Mono LCD Screen contributes to faster printing speeds and longevity. Additionally, it supports a wide range of resin types, providing versatility in material choices.

The printer's open-source system compatibility with popular slicers like Lychee, Chitubox, and Tango enhances the ease of use and customization options, which is beneficial for both beginners and experienced users. Its straightforward operation and affordable price make it a great entry-level option for novices in 3D printing.

However, the compact build volume might not be sufficient for larger projects, and post-processing requirements, such as cleaning and curing, are common for resin printers and can be time-consuming. At 22 pounds, it is relatively heavy, which could be a drawback for users with limited space or those who need a portable device. Despite these drawbacks, its high resolution and smooth surface printing capabilities are significant strengths, making it a worthwhile investment for detailed and high-quality prints.
