Hot end temperature limits

Recommended Posts

For a stock Ultimaker, setting the hot end temp to anything above 260C will generate a warning message. What exactly is the risk if this temperature is exceeded i.e. which components would need to be replaced to safely extrude, say, PC or nylon 6/6?

Yes - from a quick search it looks like that would start happening around 300 C. Anything else? PEEK is listed as having a melting temp of 343 C but I assume bad things would start happening well before that.

Would there be any issues with the temperature controller or thermocouple handling higher temps?

I'm wondering if a ceramic piece could be made to replace the PEEK component as well as insulate the brass barrel from the bowden tube. Just wondering if anybody can think of reasons why this wouldn't work before I go any further... :|

Several people designed a solid PTFE part to replace the peek part and mount the tube away from the heat. Has anyone here implemented this kind of upgrade?

I am trying to compare a custom PEEK part vs a custom PTFE part (M6 and M7 tapped), and the initial test last night with the PTFE part was printing ABS at 250C without any issues... only the bowden/brass tube interface has a higher compression rate now, and restricts the filament a tiny bit, but it doesn't impair the print.

    • "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.
