3D printing small parts

Postby LG » Tue Jul 04, 2023 12:41 pm

I'm wondering if anyone on here is 3D printing small plastic bike parts or has recommendations of somewhere to source (and what the quality is like)?

I find myself in need of some dura ace 7300 dust caps as well as some name plates for some 9 speed ultegra shifters, originals are hard to find (and expensive), but files seem to be available for printing.

As little as I know, if you have the files, there are any number of sites that will print items for you.

Only they are NOT cheap in the slightest.

Thanks, the 'little you know' is more than I know about it! The not cheap is one of the things I was I was concerned about.

Designing the files are the most difficult element.
Load the file up to a 3D printing bureau. Getting a quote is just a few clicks of a button

Shapeways has an amazing range of options in materials.

The types of plastics and machines capable of printing something at home that will work and have enough strength for a part under load is limited. Printing a design commercially is the go for anything serious.

You can sure prototype on cheaper machines to confirm your design to avoid a costly undersize opening or misjudged curve. Last part I printed worked out at about 4c per unit printed based on usage of filament. Better than $12 per part if I got them commercially printed and they didn't fit quite right, like the first set.

Isn't that the point of getting a quote?

I have recently bought some fibreglassing supplies, to make moulds for more leather saddles.
Yes, the resin and the matting cost money, but there were new skills learned, and I was very pleased with the result.

For 3D printing I just ask another brother-in-law, he has two 3D printers. He knows how to design the models and the materials best suited to the product required. And the requests I have made are simple and straightforward, unlike the projects he uses the printers for.

I would be interested to see the quotes from a 3D printer.

Well I clicked on the computer a couple times to get a quote and it seems to be $6 each in ABS resin and $8 each in nylon plus postage. I don't know much about the comparitive properties of the products other than what a quick google search provides.

I might give ordering some ultegra name plates, the DA dust caps and a couple Shimano aero stem caps a go, will be interesting to see how they come out and whether they fit!

I don't regard those prices as "scary".

I have a 3D printer and might try one of these files. :idea:

I won't be able to try this straight away, as I'm yet to have enough room for setting up the printer since we moved, so I don't want to disappoint you with a time frame.

No worries, the commercial order comes with the usual caveat that they don't warrant provided 3d files for fit etc, I'm hoping they do...

I've progressed, will report back in a few weeks once done.

How did you go mate?!
I am in desperate need of printing some spacers for an integrated seat post and tt bars :oops:
Thinking go getting some mates to have a go at designing then sending it off to someone to print...

It went pretty well, the the name plates came out a slightly unusual shape which I assume is the design in the file, but they work. Finishing required a light sand and then a spray paint. I'm not all that technologically minded so doing a design myself was beyond my capabilities.

If I needed more parts, I'd do it again.
