EP-P420 SLS 3D Printer

Eplus3D EP-P420 adopts polymer powder bed fusion (PPBF™) technology, with max up to 420x420x465mm³ building chamber size, ensures you the capability to print medium & large size parts for customized products and small batch production. Thanks to its innovative software and hardware, the EP-P420 is well designed user-friendly and cost-effective.

High Performance

  • Optimized temperature real-time management system, temperature field fluctuation ≤ ±1.0 ℃

  • Advanced optical scanning path strategy, ensures superior details and surface quality of final parts
  • Up to 220 ℃ building temperature, the machine is allowed to print more types of polymers
  • Discrete variation of mechanical properties for full-scale printing parts is less than 5%
  • High material re-use rate

High Efficiency

  • With 120w laser power, the machine has higher printing speed

  • Detachable forming cylinder, two alternative cylinders are used to shorten the time for next printing job
  • Detachable optical protective windows, makes daily maintenance easy
  • Open printing parameters, enables the development of new material
  • Distinctive scanning strategy, saves the scanning time
  • Real-time powder feeding system, saves the printing material
  • Large volume powder dispenser, one time feeding to meet the whole cylinder printing

User-Friendly & Intelligent

  • One-click scanning path generation
  • Capability to print with one-click
  • Printing report automatic generation, the printing process can be tracked
  • Malfunction automatically process, avoids damage to the equipment
