Gluing PTFE to ABS
Jan 11th, 2010 by fynflood
One question that kept coming up while assembling Mendel: “How will I make the Thermal Barrier stick to the extruder base?”
I wasn’t real sure what to go with. You need an adhesive that will bond to the PTFE, and be able to withstand some heat. I stopped by the hardware store and headed to glue section. I was kind of disappointed at the lack of documentation on most packages. I ended up going with Loctite® All Plastics.
I must say, this glue does an amazing job, and works perfectly.
The Mendel is near complete. The only thing left is wiring, and finding a gear that will work well in the extruder. I believe I have most of the firmware issues sorted out, but I won’t know for sure until it’s all wired up.
[...] That’s the Printruder II from Thingiverse printing some Black PLA. Looks like I might need to order a new tube, as Jordan reports there’s no way it’s coming unglued from the ABS. [...]
