Resin 3D Printer Phrozen Mars 5 Ultra — 4K Resolution, MSLA desktop printer

Phrozen Mars 5 Ultra is a desktop resin MSLA 3D printer with 4K resolution designed to produce high-detail models, dental patterns, miniatures and functional prototypes. The printer uses a high-resolution LCD mask to expose each layer precisely, delivering fine surface detail and consistent layer accuracy on a compact desktop footprint. Intended for hobbyists, designers and dental technicians, the Mars 5 Ultra focuses on repeatable results and accurate geometry for small to medium-sized parts.

Advantages

The Mars 5 Ultra provides 4K XY resolution that improves surface finish and captures fine features such as thin walls and small text. Its MSLA exposure system offers reliable layer-to-layer consistency and predictable curing behavior. The unit’s build volume and positioning accuracy are balanced to produce detailed prints while remaining suitable for bench-top studio or lab environments. The printer supports a range of standard photopolymer resins, enabling detailed prototypes, dental models and miniatures with minimal post-processing effort.

Suitable for

• High-detail miniatures and tabletop models
• Dental patterns and model casting masters
• Detailed product prototypes and validation parts
• Small-batch production of precision components

Key specifications

• Printing technology: MSLA (masked stereolithography)
• XY resolution: 4K high-resolution LCD mask for fine detail
• Layer resolution: adjustable layer thickness for fine to standard layers
• Build volume: desktop-class area suitable for small to medium parts
• Compatible materials: standard UV-curable photopolymer resins
• Connectivity: common desktop printer interfaces for file transfer and control

How to use

Prepare a 3D model in your preferred slicer, set layer thickness and exposure parameters appropriate for the resin selected, then generate the print file. Level and prepare the build plate, pour resin into the vat and start the print using the printer interface. After printing, remove the part from the build plate, rinse in isopropyl alcohol or recommended cleaning solution, and post-cure according to the resin manufacturer’s guidelines to achieve final mechanical properties and optimal surface finish.

Usage recommendations

Use resins and post-processing parameters recommended for small-detail work; for dental and precision applications, follow material safety and curing instructions carefully. Regularly check and clean the LCD mask and resin vat to maintain image quality and consistent layer adhesion. For best results, calibrate exposure times and use thinner layer heights for parts that require the highest surface fidelity.
