I recommend Anycubic's Photon P1 Max for big resin prints, and it's on sale

The Anycubic Photon P1 Max 3D printer boasts an impressive 18.3L build volume, making it ideal for creating large resin models and ideal for businesses or experienced makers seeking a high-capacity printer. Priced at $850 on Amazon after a $50 discount from its original $900 price, this large-format resin printer offers a variety of features designed to minimize manual intervention during complex printing projects.

The printer comes equipped with an 18.3L build volume, a 14-inch 12K LCD screen, LighTurbo 3.0 light engine, automatic leveling, AI inspection, a 1.9L heated resin tank, and ±0.01mm repeatable accuracy. These features, combined with a focus on automated calibration and resin heating, make it suitable for experienced users, design professionals, engineering teams, and small businesses who require a large-format resin 3D printer for bigger models or batch production.

In his review, Alastair praised the automated features of the Photon P1 Max, commending its ability to deliver exceptional results with high accuracy and repeatability. While the machine's dual-material printing capability is a significant advantage for some users, it may not be as appealing to those who are new to resin printing or primarily work on smaller models and decorative pieces. In such cases, a smaller resin printer like the P1 would be more cost-effective and space-efficient.
