How do thermal expansion principles work
WebNov 25, 2024 · A sweeper or recoater roller moves across the surface, picks up excess material from the reservoir and deposits new and colder powder on top of the build platform to create the next layer. Again, the powder is heated to keep it at the build temperature. This is important to hinder crystallization. WebIn this video we take a look at how the thermostatic expansion valve or TXV works in a HVAC refrigeration system and the basic working principles that allow it to meter the flow of refrigerant...
