Taulman Bridge Nylon
Hi everybody!
I am printing 'connectors' for a large structure made of tubes. As I am a bit afraid that that they could break I decided to print them in nylon which flexes more.
The quality of the print itself is very good, but I have adhesion problems.
This one came out OK, but as you can see the brim comes loose very early...
I initially had the bed at 80°C, I pushed to 95°C and it seems to be better (but does not make too much sense as it is above Tg).
As everybody seems to use glue, I used the glue I got with the printer (Blue glue stick from Staples) -- I actually never use glue on my heated bed so it is the first time I used it
The nylon should be reasonably dry -- I did not 'cook it' before use, but it is stored in a dry place and there are no bubble / pops / cracks while printing.
I have to print quite some connectors (a bit bigger that the one in the video) so I cannot afford to much print failures
Any advice?

Matter Hackers had an article on this....here it is. Maybe something helpful in there

Re: Taulman Bridge Nylon
Actually the culprit was the blue glue stick from Ultimaker...
Just used another PVA glue and all problems solved!
(Well, almost, now it is a pain in the **** to get the print off the plate )
I will carefully store the blue glue stick together with the infamous blue PLA filament from the same vendor

Re: Taulman Bridge Nylon
@Amedee, do you had any issues with the higher temp at the print head, especially at the PEEK or PTFE parts?

Re: Taulman Bridge Nylon
Not at all.
You don't need very high temperatures for Bridge (ballpark 240-245°C if my memory serves well). As long as you stay under the 250°C limit you should be on the safe side.
I printed 3 spools of bridge for this project, no issue with the PEEK, and the coupler is OK (I say OK because I never changed it since I have the UMO+ so I can't say it is like new, but Nylon didn't damage it)

Re: Taulman Bridge Nylon
FYI, just checked my GCode, and I printed everything at 245°C...
Not sure I posted the final result here:

Re: Taulman Bridge Nylon
Thank you !!
gathered some infos to generate a specific material json - here the basic input if anybody else is interested...
will start test printing soon...
[general]
version = 1
type = material
name = Taulman_Bridge
[settings]
layer_height = 0.1
material_print_temperature = 245
material_bed_temperature = 65
material_flow = 107
speed_print = 40
cool_fan_speed = 0
retraction_enable = false

Re: Taulman Bridge Nylon
It seems so - that's the info I found...
Amedee, could you please crosscheck - if it works, I'll change it

Re: Taulman Bridge Nylon
I print Bridge with the bed at 50C, and use UHU glue stick. Once the bed cools I can usually get the prints off using a penknife to lever it off.
