No, I'm angling more towards the decisions being made by/ agendas being promoted by informed, intelligent people. The MP in the original post should know about manufacturing, or talk to a party member who does.
It's not exactly the fault of the MP that the public decided to elect him to parliament even though he doesn't know anything about manufacturing. If anything that's a failure of the ignorant proles who elected him based on their own short-sighted constituency requirements.
Welcome to democracy!

We recently had a part SLA printed that was a touch under 1200mm at it's largest dimension.
Producing an injection mould is expensive, but is a one off cost.... Producing and SLS/SLA is also expensive, and costs the same for every reproduction.
SLA is a bit different to SLS as it needs support structures, I have only worked with SLS & DMLS.
Most of the companies that use SLS for production are making parts that are constantly changing and are doing very well from it.

Totally with RROB on this one, bike looks awful, but at least they are trying new things, showing us ideas, carbon fibre was laughed at once remember, its by constantly moving forward we have progress, some of it might not work but doesnt mean it never will, but yes bike looks truly grim.

I made some models in our rapid prototyper at uni, very interesting technology. It would have taken the technicians literally months to manufacture the 4 models I designed from aluminium, prototyper did it in 5 days.
I've been testing for the effect of dimple size on drag reduction of spheres for anyone who's interested:

Sorry, let me clarify. The models are made from a thermoplastic. Traditionally small wind tunnel models like those would have been hand-machined by the lab technicians, but the dimple patterns would have made it a mammoth task.
-
I think the current model is based on bribes and kickbacks.
What's the alternative? We hand over the funding decisions to the commercial sector directly? "Just pay yourselves what you think is fair"?
PBS nova did a show about printing cells to grow organs for transplants. worth watching this episode.

its interesting as a manufacturing process but not really relevant to materials useable for bikes. maybe in the future with more powerful, autonomous metal working machines it could be applicable to bikes.

spend a little time reading about it, and you will find that your statement is about 5 years old

I really hope that Scoble never gets his hands on a 3D printer. :)

It seems like it was only a few years ago that myself and a friend read an article on the concept of 3D printers and entered into an excited conversation about the possibilities.
Now, for not too many tens of thousands of pounds you can buy one fairly easily. If I win the lottery/rob a bank/marry a rich Doris...I WILL be owning one one day :D

Has this been resolved yet?
Just thought I'd resurrect this thread if only as a place to file all the junk I've been bookmarking over the years... I did have an AM for Cyclesport Fandom page but it got closed for inactivity - this seems like a more appropriate and secure repository for public consumption....
I'll post inspiration and project ideas - I've got a reasonable network of contacts in AM if anyone wants to take this seriously so I may be able to point you in the right direction, just thought this might stimulate some chat

Plenty of framebuilders printing lugs (usually on Renishaw) and then using them either to braze or bond frames (Bastion, Robot/Atherton, Sturdy cycles and many others)
Huhn print in Stainless steel and then TIG weld 853 or 953 tubes into the lugs
The results are reasonably attractive as you can achieve some clean lines

Huhn Cycles are by long-time AM-bike builder Ralf Holleis - the same guy that did that bloody awful fixie a few years back

If you're really perverse you can grab a step file of that one from his grabCAD

Here's a rather pretty seat-lug on a Donohue
The same biek also has custom dropouts - these make a load of sense as every customer has a different idea of what they want (axle Ø, bosses for rack, mudguards, discs etc so bespoke dropouts make sense and while your at it you can also add some text)
-
Bastion are also heavily into customising dropouts with text & deco
All their work is done in the am250 DMLS system iirc

Back in 2012 Charge did a run of 50 titanium frames with printed drop outs -
The parts weren’t designed for AM and are
a bit unimaginative
Article on road.cc is reasonably informative -
