Advice on Nylon G and printing with Ruby 0.40mm

[subnoizellc 2]

I am very intrigued with Nylon G. After recent success with regular Nylon, the Glass fiber filled variant fits better with a project currently using ABS.

 

The problem is when I look at the output in Cura, the CC 0.60mm nozzle makes thin walls disappear and holes appear. This would be unacceptable in the part as it is a end use part and not a prototype or reference.

 

I see I can buy the 0.40mm ruby nozzles on Amazon BUT! Do I want too?

 

Does 0.40mm compromise the material's properties? Does it just look ugly?

 

Thanks for the help!

 

Maybe this isn't a hardware question, sorry if I am in the wrong place...

I've done some Nylon with carbon fibre with standard 0,4mm nozzle and that came out with a superb finnish.

Parts were pressurised to 5 MPa and connected to a solenoid that reached about 100°C so I wouldnt say material properties were compromised by nozzle size.

Didi it first in PETG with carbon fibre but it got too soft after a while and deformed under pressure so I know material properties was under strain in that application.

 

Maybe glass fibre is different, never tried that

Good to know! This would be for a high heat and repeated shock use case so all relevant info.

 

Thank You!
