Print more than 260ºC with a UM2.

Where did you found the vespel 1/4 "diameter part, to make your mixed vespel ptfe coupler?

 

I bought it from Goodfellow (http://umforum.ultimaker.com/index.php?/topic/7024-teflon-spacer-replacement/page-5) - I'll also soon give an update on my experience so far.

hi,

I think I found the solution to print more than 260 without burning the coupler.

I have made a coupler in Duratron.

working temperature 310 ° C.

Here pictures of my first test with pla.

I've also tried it with no problem with XT ColorFabb color.

I have to do more tests.

see you soon. :-P

Cool! (Well, not literally)

I had thought 260C would already be on the limit for PLA - but you got good prints with 310C?

How easy/difficult is it to machine Duratron?

Anyone ever did check the PEEK HT?:

PEEK HT is also available as a glass filled material

The new Victrex® PEEK ST material has been designed to give all the benefits of Victrex PEEK 450 with the additional that the operating temperature can be taken to over 300°C, improved mechanical performance between 150-200° C is particular enhancement in PEEK ST over the standard PEEK polymer materials. Reinforced materials are available with glass and carbon as a filler, and can be used up to 380°C.
