5 Best Large Sized SLA Printers in 2023

When it comes to 3D printing, most people tend to think of FDM (Fused Deposition Modeling) printers, also known as FFF (Fused Filament Fabrication) printers. However, there is another type of 3D printer that offers even better print quality and accuracy – SLA (Stereolithography) printers. The main difference between FDM and SLA printers is that the latter uses UV light to cure a liquid resin, layer by layer, instead of extruding melted plastic. This results in smoother surfaces, finer details, and higher resolutions.

There are many SLA printers available on the market, but not all of them are suitable for printing large objects.

1. Formlabs Form 3L

The Form 3L is the largest 3D printer from Formlabs, a pioneer in SLA printing. It has a build volume of 13.2 x 7.9 x 11.8 inches, which allows you to print large models in one go. It also features a new low-force SLA process that reduces the strain on the printed parts and increases the accuracy. The Form 3L supports a range of materials, from standard resins to high-temperature resins, and has a user-friendly interface with wireless connectivity and automatic resin handling. However, the Form 3L is quite expensive, starting at $9,999.

2. Peopoly Phenom XXL

The Phenom XXL is the largest 3D printer from Peopoly, a well-known brand in the SLA community. It has a build volume of 17.7 x 12.6 x 20.5 inches, which is larger than any other desktop SLA printer. This means you can print huge models or multiple smaller models at once. The Phenom XXL uses a MSLA (Masked Stereolithography) process that combines LCD masking and LED lighting to speed up the printing process without compromising the quality. The Phenom XXL is affordable for its size, starting at $3,799, but it requires some assembly and calibration.

3. Elegoo Saturn

The Saturn is the largest 3D printer from Elegoo, a budget-friendly brand that has gained popularity among hobbyists. It has a build volume of 7.5 x 4.7 x 7.9 inches, which is not as big as the previous two printers, but still larger than most SLA printers. The Saturn uses a 4K monochrome LCD screen that allows for faster printing and longer lifespan. It also has a dual linear rail system that ensures stable and precise movement. The Saturn is very affordable, starting at $499, and comes fully assembled and ready to use.

4. Phrozen Transform

The Transform is a versatile 3D printer from Phrozen, a company that focuses on industrial-grade SLA printing. It has a build volume of 9.1 x 6.1 x 15.8 inches, which is tall enough to print vertical objects. The Transform uses a ParaLED technology that provides uniform UV light distribution and minimizes the exposure time. It also has a tiltable 13.3-inch 4K LCD screen that can be adjusted to achieve better accuracy and reduce the support structures. The Transform is relatively expensive, starting at $2,999, but it offers a wide range of features and upgrades.

5. Longer Orange 30 Pro

The Orange 30 Pro is the latest 3D printer from Longer, a brand that offers affordable and reliable SLA printers. It has a build volume of 4.7 x 2.6 x 7.9 inches, which is the smallest on this list, but still comfortable for most projects. The Orange 30 Pro uses a 2K mono LCD screen that enables faster printing and better details. It also has a cooling system that prevents the resin from overheating and a touchscreen that allows for easy operation. The Orange 30 Pro is very affordable, starting at $269, and can be upgraded with a Wi-Fi module and a resin sensor.


The choice of a large-sized SLA printer depends on your budget, your printing needs, and your level of expertise. If you need a professional-grade printer with high-end features, the Form 3L and the Phrozen Transform are the way to go. If you want a more affordable option that still delivers great results, the Peopoly Phenom XXL and the Elegoo Saturn are good choices. And if you are new to SLA printing or have a limited budget, the Longer Orange 30 Pro is a great entry-level printer. Whatever printer you choose, make sure to follow the safety instructions and handle the resin with care.
