What to Check

Physical Access

  • Verify either the crate (990 x 990 x 1095mm | 39 x 39 x 75 inch) with lifting device or the un-crated printer on wheels (710 x 710 x 1675 mm | 28 x 28 x 66 inch) can navigate to the installation location (doorways, elevators, etc).


Safety and Health 

  • Ventilation for the area where the printer is operated - air exchange every 15 min suggested
  • Ventilation for the area where parts are washed - air exchange every 5 min is suggested for most solvents and apparatus
  • Have the following on-hand incident response equipment:
    • Class ABC fire extinguisher
    • Eye wash station
    • Spill kit
  • Have the following on-hand personal protective equipment:
    • Nitrile gloves
    • Splash goggles or glasses
  • Obtain permits, if required, to use, store, dispose, or recycle solvents and resin. Refer to SDS at Most jurisdictions don’t require permits for quantities under 20L.
  • Dedicated waste storage for resin contaminated wipes & gloves. This may not be a hazardous waste in your jurisdiction. Nexa3D recommends treating it as chemical waste.
  • Waste storage for used solvents. Most jurisdictions consider typical solvents used a hazardous waste. Storing in labeled UN or DOT certified containers is recommended.
  • Safe storage for solvents and resins may require spill containment or flammability ratings depending on the jurisdiction and quantities stored.


These are recommendations. Defer to local requirements.



  • Each printer requires floor space of 1.4m W x 1.9m D (55 x 75”). The power switch is on the rear of the printer.
  • The printer requires conventional grounded power outlet. NA model printers require 100-130VAC / 8A, and come with a 2m NEMA 5-15P power cord. EU model printers require 200-250VAC / 4A and come with a 2m Schuko power cord. Alternately the user can supply their own IEC320 C13 power cord with wall plug of their choice. A 500W UPS with surge protection is recommended.
  • Flooring should be washable and water tight in case of spills or drips.
  • Ambient UV light in spectrum 350-415 nm should be minimal. Fluorescent or LED lighting is preferred. Windows should have UV blocking film.
  • Washing area may need access to water and drain (depends on solvent used). Don’t put resin or flammable liquids in the drain.
  • Any dust generating activities should be physically separated (sanding supports, foundry activities, etc)



  • Solvent (at least 4L) is required to clean the printed parts and build platforms. A moderate-sized self-sealing basin is included with the printer. It is recommended to have a few larger basins (20-40L) available to wash large prints. Nexa3D recommends using xClean solvent or Isopropyl Alcohol (IPA). Other solvents may work, but are not supported by Nexa3D (TPM, DPM, Propylene Carbonate).
  • A cure station emitting 365 to 405nm UV light at a density of 2.5mW/cm2 or greater, and able to control temperature up to 80°C is required to achieve full mechanical properties of all resins. A full build with build plate has dimensions (300 x 180 x 488mm | 12 x 7.2 x 19.2 inches). Curing on the build plate is required for some part types.



  • Windows 10 or Windows 11, 64-bit, 16GB RAM (32GB+ preferred), 5GB free disk space, Graphics card with >4GB RAM. Due to computational nature of the software, processing speed benefits from a high performing CPU, look for something with 4+ cores and 2 GHz+.
  • A license for one of the following build processing software packages:
    • NexaX 2.0 (preferred)
    • MagicsPrint for Nexa3D
    • Magics RP with Nexa3D BP plug-in
