Dental laboratories running Straumann P series printers are the clearest fit. Every printed part leaves the build coated in sticky resin, and the P wash moves it straight from the printer into an automatic isopropyl alcohol cycle that takes about 10 minutes. Technicians load the unit and move on to the next job, without cleaning parts by hand or touching them while they are still coated.
Practices that print in-house with the P series use it the same way. Each cleaning programme is specific to a material. A team working with more than one resin selects the material on the touchscreen, and the cycle runs with its settings. The result is consistent handling for every print, regardless of who loads the unit.
The P wash also fits a printing room layout. A direct data connection links it with the printer over WLAN or Ethernet. Straumann's P cure stacks with it, so the cleaning and curing steps sit together in one column beside the printer. At 235 mm wide without its iso container, and 344 mm with it, the unit needs little bench space.
Rooms where printing runs through the working day benefit from the built-in active carbon air filter and a design that keeps cleaning-liquid consumption low. Batch size follows the 119 × 160 × 99 mm cleaning chamber, so each cycle's parts must fit within it. Isopropyl alcohol is the cleaning agent, making it the unit's main supply from one cycle to the next.
