OneUp Announces New EDC Tube Strap Mount & Inline Pump Mount
Totally agree, these work though. https://www.cyclesolvers.co.uk/product/pumpstrapOneUpEDC/13

This works, and if O-ring snaps just buy new O-ring. https://www.cyclesolvers.co.uk/product/pumpstrapOneUpEDC/13

Tech Week 2023: 3D Printed Randoms from Jank Components, 76 Projects, & More
Agreed... but the alternative is that none of these useful, but niche products would exist otherwise. Spending thousands on injection mould tooling for a few hundred parts doesn't make any sense. Enter: 3D printing to fill the gap. If OneUp thought there was a business case for selling an inline pump mount, it would probably be for sale by now. That tells you everything you need to know about how 3D printing fills the viability gap

@brianpark: This is such a great idea. Some kind of global 3D printing collective and a map to show your 'friendly local MTB printshop' where you can collect your locally printed components. Maybe some sort of franchise model to buy-into a library of designs to print locally. Or the 'no dig, no ride' philosophy, where you can have access to a 3D model library, provided you upload your own designs too... lots to consider.

Tech Week 2023: 11 Manufacturers Offering 3D-Printed Bike Gear
Yeah, this is the future. Parametric CAD modelling plus 3D printing. I believe its what Atherton bikes are using to input customer specific geometry, to then print custom frame lugs etc. Only takes a couple of minutes to update the CAD files and output the 3D print code with some good workflow. Agree there are good applications for bike contact points like grips/saddles/levers etc, but the safety critical aspect of some components needs careful consideration. If you're interested in this type of stuff, I've got a parametric CAD model for generating water bottle mounts for awkward frames (shock clearance issues etc). Customers can measure up where they need to move their bottle and a bespoke mount can be printed for that frame. Done lots of Marin eBikes and a few Starlings, plus the occasional Bird.

@vinay: Yeah agreed with most of your points. Depends on the type of plastic as to whether the runners/flash can be re-ground and fed back into the hopper. A good 3D printing designer will try and limit the supports required through good design practice. I only use supports on my designs if I can't see any way around it. Most FDM printers don't need to print a baseplate either, so almost no wastage from filament roll. Most parts designed for 3D printing can be optimised to reduce waste. With regard to injection moulding vs 3D printing, you have full flexibility as a designer to tune wall thicknesses and infill parameters as you wish, so you can mimick an injection moulded part (with ribs or not) if you want. You are much more constrained with internal features when designing for injection moulding, as undercuts and any complex internal geometry adds significant additional cost and complexity to the mould tool. Injection moulding does win on tolerances and isotropic material properties though, as you don't need to worry about layer lines (from FDM printers at least). Totally agree on disadvantages for printing common mass produced household goods, but for low volume specialised bike parts I think it's great!

@dirtyburger: The production method means you don't need to invest in expensive injection mould tooling for a very limited run of niche products. You can also go from an idea to a functional object in less than a day (which is both good and bad if the idea is questionable!). Ultimately it allows niche products to be created quickly and cheaply, many of which would have zero business case if up-front tooling investment was required. I agree that for generic mass produced products, there is little benefit over traditional methods.

Although printing isn't the most efficient in terms of speed, or component cost, it's generally less wasteful than injection moulding in terms of raw material used. The big environmental win for printing is in the supply chain if enough local printing facilities/shops exist. You go straight from raw material, to printed part, to customer. No C02 heavy distribution chain between the injection moulding process and the end user.

5 Original 3D Printed MTB Accessories
@brianpark: Yeah totally. As you know, there's still a long way to go in terms of automating 3D printer setup and use for every home, but I could imagine a not too distant future where bike shops could have a printer for plastic components/accessories and customers could choose from an online library of parts to print-on-demand...

One of the lesser seen benefits of 3D printing could be the significant reduction in emissions from supply chain and distribution. If the components are printed locally to where they are used, you only have the raw material (filament) distribution to worry about... No component warehouse and distribution burden, no postage. Also, if you are careful about creating designs with no support material, then no waste plastic in the printing process compared to certain mass production techniques. As such, I'm happy to print designs for MTB locals in South Wales, UK. www.cyclesolvers.co.uk
