3D Solex changeable nozzle

Recommended Posts

After printing with the standard 0.4 nozzle and Carls (http://3dsolex.com/) changeable nozzles (0.4 and 0.6) i must get two things of my chest:


  1. Why does UM not put the changeable nozzle standard on all UM's? Changing the 3Dsolex nozzle is a piece of cake and different nozzles give different results and advantages. When the nozzle is ruined by bamboo (frustration...) or another experiment, you simply change the nozzle in a minute.
  2. Nozzle 0.6 really rules. A 0.6 shell is solid enough, so one 0.6 shell layer is enough. With 0.4 nozzle you print a 0.8 shel, so you print the shell twice. With 0.6 that is just once and that saves some filament and loads of time. In normal print work i do not see the difference with 0.4

While a changeable nozzle system is certainly desired on a FDM printer, I understand why UM is not stressing too much on changing the hotend.

First, they might have a significant number of heater blocks / hotend of the current design on stock. Second, changing these parts might make it necessary to repeat some offical tests like EMC which is ususally quite some money.

I bet they are working hard to make the next think. I hope that they make this ideas and many others a reality and that they don't forget umo machines releasing upgrades for it too , specially a new extruder or better fan setups (yeah you can mod it but if you break it it's a mess and with good air flow calculations from guys that know how to make stuff it would really rock).

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
