Islabikes calling it a day

In the era of 3D printing I very much doubt even non-standard parts' breakage is too much of an issue.

Hmmm plastic hangers !

Why would you 3D print the hanger in plastic? Even Reynolds of tubing fame use 3D printing now for stainless BB assemblies.

I had assumed it was based on the misapprehension that 3D printing was only possible with plastic, hence my response, but interesting to see an actual printed metal cycle part 'in the flesh'.

How feasible/affordable would that be for a one-off?

(e.g. gear hanger)

3D printed metal parts can be about as strong as traditionally manufactured parts.

The crucial step is getting the CAD files for the proprietary components. With those it's then possible to choose from an ever-increasing range of manufacturing methods.

So are you saying: "it can be done." ?

If so; thanks, but that's not what I asked!!

I think gear hangers are CNC milled. If I’m right: very possible/simple for someone with access to the right material and machine, which I think is how come there are specialists who make and stock ‘every gear hanger under the sun’ (except the actual one you need!).

Yes, most are flat with a few raised and recessed bits. With current technology it's probably most convenient to start with computerised cutting and finish with computerised milling. The crucial part for the future is the design spec: then you can use whatever technology you choose.

I contacted a 3D printing company for you. Unfortunately they took some time to answer the chat with a follow up question, at which point I had gone off to make lunch.

That's quite understandable - thankyou for trying. :- )

I was joking !!!!!

[Brucey]

when I last looked at an Islabike, they had nothing on them that could't be replaced, repaired or made again..IIRC the main obstacle to replacement was indeed identification.
btw the typical manufacturing route for gear hangers is, I think, to cast them, and then tap the threads. I have yet to see the gear hanger I couldn't have made cheaper/better/more quickly from welded steel though.

Wouldn’t making one from steel defeat the ‘sacrificial’ purpose? I suppose you could incorporate a deliberate failure point.

Making one by hand from aluminium wouldn’t be a huge job if you had access to suitable material, a pillar drill, and the right taps …… but I guess most of I don’t.
