Notices Before Purchase！

*Pre-owned machines can only be repaired and cannot be returned.

*If required, parts and accessories can be purchased separately depending on the condition of the machine.

Condition Notes for Pre-owned Machines:

• New/ Open-box -> The item is in like new, never used/assembled condition. It's returned due to buyers' remorse or fulfillment error. It may only show sign of repackaging due to our inspection service (opening the box, taking photos, recording serial, classifying grades). It's sealed, packaged in the original factory condition with ALL original factory parts/accessories in inspected new or like new condition.
• Good Used -> This item was inspected, cleaned, repaired to full working order and is in overall good condition. It WILL contain aesthetic signs of wears/tears/scratches (especially on the Tank/Lid). This item may be repackaged. *REMINDER- this is a used unit. NOT REFURBISHED.
• For Parts Only -> The unit has damage in functionality (e.g. a bad LCD/Z axis). It needs fix-up & touch-up to be fully functional. It usually contains signs of wears/tears/aesthetic issues such as scratches, dents/cracking. It powers on. It might miss one or ALL minor parts/hardware/accessories. Customers MIGHT need to buy up to 2 units with us in order to make 1 functional unit. Great as DIY fix-up projects for experienced DIY experts.

Pre-owned units might miss one or all complimentary none-essential accessories of total value under $10 that buyers will need to purchase those on their own like plastic scrapers, SD cards, Allen wrenches back up hardware pack etc.

This is almost the biggest difference between new and used units with us besides some normal signs of use/wears.
*for resin printers - users should expect to replace ACF/FEP/PFA sheets on their own.

【9.1-inch 6K Mono LCD】 MARS 4 Max features a 9.1-inch monochrome LCD screen with a resolution of 5760x3600 and an XY resolution of 34um, and printing speed up to 70mm/H. The 9H hardness tempered glass with excellent light transmission protects the LCD screen from scratches and damage caused by resin dripping or penetration.

【COB+ Refractive Light Source】MARS 4 Max adopts the COB+ refractive light source to ensure that the emitted 405nm wavelength beam is more vertical and uniform on the entire LCD screen after refraction. Paired with the full grayscale anti-aliasing algorithm to make printed models with finer and more realistic details and a smoother surface.

【Large Build Volume】The large build volume of 195.84x122.4x150mm (7.71x4.81x5.9 inches) provides you with more creative space to print a large model or print multiple parts in batches, thus increasing your productivity.

【Efficient Heat Dissipation】Double fan cooling system design, one for air inlet and the other for air outlet, has faster air circulation and higher heat dissipation efficiency, which extends the service life of 3D printers.

【Voxeldance Tango Software】It has 3 printing modes: static mode and dynamic mode (including smooth and high-speed mode). In dynamic mode, when the printed model cross-section is small, the print lifting speed is faster to improve printing efficiency; on the contrary, the printing speed will slow down. Combined with self-developed new open-source GOO slicing format, which supports multiple slicing software without restriction.

【Refreshing Printing Environment】The plug-in air purifier with a built-in activated carbon filter reduces resin stink for a refreshing printing environment. In addition, 's first large-sized air purifier (210x247x410mm) with 95% VOC purification efficiency will be available soon. (Requires separate purchase)

6K Printing Accuracy

With a 9.1-inch 6K mono LCD screen of 5760x3600 resolution, you can print out highly detailed models at 34 microns XY resolution, with a faster printing speed of up to 70mm/H and a curing time of only 1.5-3s per layer.

The replaceable tempered glass with 9H hardness effectively prevents scratches and damage to the LCD screen and prolongs its lifespan of LCD screen.

Stable Printing Performance

The 20mm thicker Z-axis linear guide rail effectively reduces the vibration amplitude during Z-axis movement and the layer pattern of printed models for a better printing effect. The sandblasted build plate increases model adhesion for a higher printing success rate.

Smoother Surface Finish

The COB+ refractive light source ensures that the exposure of the 405nm wavelength beam across the LCD screen is more even and vertical with consistent accuracy. Combined with full-grayscale anti-aliasing algorithms, which significantly reduces the "staircase" effect, resulting in finer details and a smoother surface finish.

An Efficient Ecosystem

The dual cooling fan structure dissipates heat faster and more efficiently, thereby extending the service life of MARS 4 MAX.

The air purifier is connected via USB, with an activated carbon filter to reduce resin odor in the printer chamber. You can also choose the upcoming 's first large air purifier, which can remove formaldehyde and up to 95% of VOCs.

More Practical Features

PFA release liner film with less release tension for easier model removal and a higher printing success rate.

3.5-inch color touch screen with an intuitive UI interface is highly responsive and easy to operate, and support multi-language free switch.

Multiple Printing Modes

The Voxeldance Tango Software provides 3 printing modes: static mode and dynamic mode (including smooth mode and high-speed mode). When selecting the dynamic mode, it will adjust the printing speed dynamically according to the cross-sectional size of the printed model, which reduces the influence of release force and improves printing efficiency.

Besides, has self-developed a new open-source GOO slice format, which is compatible with third-party slice software, such as CHITUBOX and Lychee Slicer.
