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.

9K Print Quality

The 7-inch 9K monochrome LCD with 8520x4320 resolution and 18x18 microns XY resolution allows you to print models with extremely fine details and sharp edges at a printing speed of up to 70mm/h, achieving superior quality and precision.

Super Stable Structure

The Z-axis is driven by a linear guide rail that ensures stable and precise movement during printing, effectively reducing the layer texture and making the model surface smoother.

The non-slip hexagon socket leveling screws are simple to handle, making it easy to level the build plate.

The laser-engraved build plate provides excellent adhesion during the printing process and easy to remove printed models.

The printer's mid-plate is designed with a raised step to prevent resin from flowing inside the printer and causing any damage to the printer's internal components.

Powerful COB Light Source

Mars 4 adopts a powerful COB light source consisting of 36 LEDs hidden beneath a monochrome LCD that work together to provide a highly uniform UV light beam throughout the build area. The result is your printed models with exceptional precision and smooth surfaces.

Efficient Heat Dissipation

With a large cooling fan and heat-conducting copper tubes next to the COB light source for fast heat transfer, this ensures efficient heat dissipation performance and prolongs the service life of the printer.

Voxeldance Tango Slicer

Mars 4 uses Voxeldance Tango Slicer, which offers three printing modes of static mode and dynamic mode (including smooth mode and high-speed mode) to improve printing efficiency and optimize your prints for quality and speed, or a balance of both.

The open-sourced GOO slice file is compatible with third-party slicing software, giving you the freedom to choose the best slicing software for your needs.

Better Printing Experience

The upgraded USB air purifier comes with a plastic protective case that protects the built-in activated carbon filter and absorbs and filters resin odor during printing.
