Okay so it is fairly well documented that I don't like replicas.. however this is very very clever and provides some insight into what the future of our little hobby could look like : www.replicadb4.com/default.aspxI hope the images work ![](http://www.replicadb4.com/IMAGES%2f2013%2f06%2f52pc1.jpg.jpgx) ![](http://www.replicadb4.com/IMAGES%2f2013%2f06%2f35_2.jpg.jpgx) DB4-in-a-box ![](http://www.replicadb4.com/IMAGES%2f2013%2f09%2fbits.jpg.jpgx) Interestingly he is actually building a plug which I'm guessing is going to get fibreglassed or something? Now if you match up this idea with 3D printed metal : or this : and you get a situation where in the not too distant future it will be possible to get good quality/accurate body panels printed in a variety of materials. I'm sure engine parts would be possible too, but I don't know enough about the engineering of metal in regards to the stresses and strains that this stuff can take. This stuff could be amazing for the custom scene too.

Blimey. It's brilliant living in the future, isn't it?!

well i know charge are using 3d printed metal parts on there bikes now, so i guess anything will be possible very soon, i have been looking at 3d printers for a few hobbies i have.... it would be so easy to make almost any model shell (1/18th 1/24th) also you could replicate alot of interior parts very easily.... i would love to geta 3d printer right now lol

Impossible-to-find trim parts, for any car, cheap, anywhere in a few minutes/hours.
Oh how I want this right now!!!!!

I don't know about the metal printing but I've had plastic manifolds printed up for work from a 3d cad model and it's a really easy way of making complex shapes. The only negatives I have found are poor surface finish and porosity.

The only negatives I have found are poor surface finish and porosity. If you are using Resin or Plastic Rapid Prototyping, the surface can be improved, by reducing the amount the table drops, If you want to stabilise the resin I know somebody who can Plate Rapid Prototyping bits, Vastly improves the surface finish and really does increase the strength of the item, Various metals can be applied too, Titanium, Chrome, Copper, Nickel

Atmo V8 Power . No slicks , No gas + No bits missing . Doing it in style. Austin A35van, very different------- but still doing it in style, going to be a funmoble

Was discussing this with a colleague of Hardcore's at the weekend.
It will come to a point where your local motor factors will be a bank of 3D printers and a bloke with a computer. The only stock they'll hold will be raw materials, and there will be no component obsolescence.

I will get round to finishing it at some point

3D printing is nothing new, they've been rapid prototyping using a virtually identical process for the last 25-years - SLA and SLS. The thing that's made it new is that the machines have got smaller and cheaper and in theory, you can print from your desk top....
SLA uses a resin and is built up a layer at a time - usually, sub 1-micron - then cured by laser. It's not instant, it takes time to produce a model but using this process it can be extremely accurate. The surface finish is dictated by how the model's designed and therefore, how it's built.
The process sounds great but you won't be able to just feed materiel in one end and a completely finished and polished component will pop out the other - it doesn't work like that!
3D printing has been in use in F1 for ages - they usually build the wind tunnel models half size, then electro plate them with nickel to make them structurally integral - that way you can throw 200-plus-mph winds at them and they won't fall apart. I work part time for a company that does just this - and they're all ex-F1.
The printing of the Aston Martin again is nothing new - the same company I work for has been doing panels for concept cars for ages now - using SLA, then elctro-plating, then they're painted etc... Or, they can be copper plated, nickel plated or chromed, gold plated etc etc...
We've already made bumpers for cars that you can't tell from chromed steel - next time you see it, look at Kev Jenkins XE Turbo-powered Mk1 Escort racecar - the bumpers are our chromed plastic ones - they weigh the proverbial cattle-truck-all and look like chromed steel! Imagine that concept on the front of a 57 Chevy! Or the fact we can make bumpers that never existed.....
The thing that makes the whole process interesting and potentially exciting, is that they can print metal - well it's a sintering process to be more precise - a bit like powdered metal conrods....
The other thing that you need to think about though is, it's very nice being able to print your component for your car - and yes you will be able to and no you won't at the same time because it's not quite as straight forward as simply printing the thing off... Is, that it will virtually wipe out the engineering trade over night once they've cracked it. Think how things are made - currently, you can't make a cavity within an object without making it in two parts - with printing you can. If you can do that, why will anything need to be machined again? - thus wiping out the engineering industry!! Bit doom and gloom maybe but think about it - technology maybe great but some of the implications, aren't!

I work for a mainstream manufacturer and we use multiple Rapid process to make a wide range of parts, we have made dash boards and door cards to production standard for show vehicles, bumpers all that kind of thing. Not cheap though £5k+ as the size increases.
Do a lot of prototype engine intake ducting but are also metal work as well, the most impressive thing I have seen is a fully functional complete V12 engine head, made as a one off for a prototype!!
So the tech is there to make anything but the costs for large/complex stuff is still to high for our sort of applications. Like anything it will be a matter of time!
