PTFE versus PEEK thermal insulating barrier

Posted on by

How do you choose whether to use a PEEK or PTFE barrier?  Well, I asked the benefits of using PEEK over PTFE thermal insulating barriers in an extruder assembly and Nate True gave a fantastic summary:

PEEK is more rigid and won’t bow out and leak everywhere with ABS. It would be better for PLA except that PLA likes to stick to everything. So PTFE (being not sticky) is preferable for PLA. ABS is very slippery by comparison so PEEK is more than adequate for it.

I’m still rockin’ my black ABS coil, so I’ll probably have to add a PEEK barrier to my MakerBot wish list.1

New print: Beco Block!

I printed up my first Beco Block today – and I can’t wait to print up more.  Nate True was kind enough to download the STL files, center, align, save, and zip all of the various pieces. 1

I’d like to see a new STL file out there that has several different types of these Beco Blocks all on one sheet (similar to Spacexula‘s Mendel production STL files).  I could really see myself cranking out these by the dozens.  In fact…  once I had a sheet designed with a good mix of the various parts I could put it through the MakeNBreak script to churn them out.
