I bought the Micro-Swiss plated all metal throat and nozzle about a month ago. I have been printing with it from 196C up to 260C, switching back and forth a few times to test this thing out running it 24/7 on a production printer. I am loving the setup so far, this takes out the largest downside the the MK8 extruders had. The current nozzles can usually handle lower temp PETG but the makergeeks Higher Temp PETG seems to cook the PTFE liner. These are also wear resistant to help with blended materials that would usually wear the brass nozzles quickly.
I have been emailing with micro swiss and got a chance to meet them at MRRF after I purchased the setup but before really testing it much. They have confirmed it is “high temp suitable” but I have not gotten a max temp from them yet.
I am trying to get some in the shop as I feel it is an amazing upgrade for anyone interested in exotic materials. Keep an eye out, I am going to try and offer the naked parts and maybe a custom mk style setup. I truly prefer the MK style extruders for many reasons but as always there is room for improvements. I have a ton of ideas and have been slowly working my way through them to hopefully make a good thing even better.
The current MK8’s usually last me about 3 months before the “PTFE” liner needs to be replaced for one reason or another. I also have a sample of some “improved” PTFE from Capricorn captubes.com just in case.
