Title: Anyone want any brass inserts for nozzles?
Post by: alanambrose on October 03, 2018, 10:43:24 AM
I'm getting some quotes for these and it seems they need to be made in a big-enough quantity, e.g. 100-off, to be economical. Anyone interested? This is the 'RVT07' design:

Was that from UK ? Did you look at any prototype-oriented Chinese suppliers - might be worth a go for something like this where most of the cost is setup, and shipping weight is minimal
e.g.
https://hanzmanufacturing.com/

A few listings like this on Aliexpress suggesting pricing of $150 for a lot of 100 small parts

>>> How much did they end up costing?

Waiting for the duty charges to come through, but about $5 a piece. I went with some guys I had used before to reduce the risk a bit.

Sorry to be slow to reply - I've been quite busy. It was ~£3 each plus shipping, duty etc. Say, £35 + VAT for 10 shipped?

Are people using 3d printed nozzles with these brass rings?

Post by: alanambrose on September 12, 2019, 05:18:54 PM
Yeah I am, but atm it's a bit of a craft industry :). That is, drilling out the 0.4/0.6mm hole is a bit hit and miss, and I find I need to ream out the body a bit to fit the brass insert. I successfully made some smaller o-ring-based nozzles for domed LEDs, but I wouldn't necessarily recommend the process :). The process and fit could be improved given enough time and energy.

I did notice recently that EDM (i.e. tiny) tubing is available and that presumably would make v. exact nozzle tips. Alternatively, simply making a head that accepted off-the-shelf Juki nozzles would presumably do it.

Hi Alan

I tried printing some on my Prusa i3 Mk3s but I could not get the fine nib end printing properly. What do you print them with?

A formlabs/SLA but using 3D hubs (which seems to have fallen apart now).

Printing the adapter for the samsung nozzles worked perfectly

and they can also be fittted to broken originals ( if you remember my post )

I've been using one as my smallest nozzle for the last 20000 components or so.
