Although 3D printing is a boon to the technical world, but we sometimes get it backwards. True, we don't have to print parts of a car. There is practically verry little home use for 3D printers. Suppose if a car meets with an accident, and gets badly damaged, the customer would have practically no reason to print the parts himself, but if the automaker supplies 3D printed parts then the costs would significantly reduce both for the customer and for the automaker.

AnandY, i am not sure that the cost would be cheaper for a 3D printed auto part.  It might be, but mass produced parts are still going to be much cheaper than 3D printed parts.  3D is good for low rate parts and specialized parts.  Injection molding can also be used for relatively low rate production at a much reduced cost.  On the other side, mass produced parts are typically produced and stored and then shipped, which 3D printing does not require.  On the 3D printer side, printers would need to be distributed, rather than the parts.  Finally, it takes a while for a 3D printer to make a part, compared to a mass produced part.  Is that time going to be less than getting a part out of a warehouse?  It is a close run thing.  The big advantage for 3D printed parts is the fact that one does not store the part, just the bits required to drive the printer and the raw material.

As you can see, the economics of it are a little bit complex when talking about mass produced products like a car.

3D Printing Awareness

Chris, I agree with many points in your article.  The general public is now 'discovering' 3D printing and is truly excited about it.  As stated in the article, some applicatiions adapt themselves very well to 3D printing, while some applications do not (because they are not economicaly feasible).  All in all, I'm glad the general public is now aware of 3D technology because it does help raise awareness to science and math for our youth and might inspire some kids to choose a career in STEM.

@Greg: Yes it has risen from something which we all never expected of. Anyway there will be many more advancements in the near future

Greg,

The field of 3d printing a bit more complex than what you're describing. There are 3d printing who printing in strong metals , and it's already used sucsessfully for applications in dentistry and aviation and others. Andwith regards to cost, because 3d printing is less limited in what it can make than other manufacturing methods, it's sometimes  more cost effective (or the parts perform better) than non 3d printing. And there a new methods of 3d printing , or techniques(availbl or indevelopment) that combine 3d printing with cnc or with injection molding that can toghether are cheaper than manufacturing in volume,at least to low/medium volumes.

In general,once i was none believer in the general vision for 3d printing, but after reading about all kinds of crazy innovations being worked on in this industry , and the amount of money/effort on r&d ,i think it's hard ot predict how far 3d printing can go.

And with regards t the "vanishing engineer" issue - yeh that's pretty absurd. Why would 3d printing do that ?

@andyk1: Yes , 3D printing has a great future ahead and already started with a bang. I also don't see why they opt for something like that.

it still needs to find it's home market.

 

but  laser printing took a while to take

The area of automotive parts where 3D printing could be valuable is in the restoration of old cars. Trim and ornaments for starters and then some of those suspension parts that cost way too much to get machined. Possibly it would be good for a few just plain old car parts as well, if there is no better source.

BUT every part needs to be designed, and the original writer should know that just because a part is drawn does not mean that it was engineered or designed. A whole lot of people are intensely clueless in thatr area. 

3D printing is indeed a neat tool to have, but like all other tools, by itself it is of marginal value. It still takes both skill and understanding to do things right. That won't change no matter how many great tools we get.

Anandy The good news is reducing the price of the part and the bad news is it will true only for the single material part.

And also Anandy , to having a 3D printer at home for pint the parts that you want is not seams to not like a good idea.  Best place it to have that body parts printer is with the parts shop.
