Strengthening the Nozzle

[Gary]

Has anyone attempted to modify the nozzles in any way to strengthen them? An earlier post said

Bent and broken nozzle tips

I’ve reduced the problem to a 5-10% bend angle by superclamping with brackets.

I googled superclamping and that went to snowmobiles … so … I don’t know what that means.

I am seeing nozzles get bent by simply softly wiping them. We can always be more careful, but with multiple people using the machine (students), and new students coming every year, this problem will keep going on. I LOVE the Voltera - so much better than milling machines we have used in the past. Great for paste - just wonderful. But these nozzle tips are driving me nuts!

What can we do to strengthen this tip? Has anyone tried heat shrink? Solder? (that seems like not the best idea. Heck - Duct Tape? Dipping it in hot glue? 3D printing a microhousing? Creating a tiny robot that lives on the edge and comes out every hour like a cuckoo clock and straightens it? I need help with these nozzles.

Several months ago I was thinking the same thing and spent a little while chasing up information about other nozzles. These ones appear to be quite robust.

Tecdia arque_nozzles.pdf (2.4 MB)

The nozzles from 100µ and upwards are US$120 each with an MOQ of 3 of each size.
The Voltera standard 225u nozzles are US$50 for four.

Without knowing if the Tecdia nozzles would work with the Voltera physically or with their software I wasn’t about to buy three of them just for testing, I could get 28 of the Voltera ones for the same outlay, and I don’t break them that often.
However perhaps someone from Voltera could comment, it would be really good to have something a bit stronger!
