3D printer?

In the near future we will see replacement parts being printed. If you think that the technology won't improve to where 99% of the parts on your Norton can't be printed you are delusional. Now whether we see it before some of you guys "retire" that is yet to be seen.

Gidday to All.
I think Swoosh Dave has the most relevant comment. Though I would not call people delusional. There is always resistance to new ways. its part of being human.

As a living dinosaur and fully paid up Luddite, I speak from experience.

A long long time ago people turned lathes by human power.

When metal spraying 1st came out it was rubbished. look at coating technology now. Sintered metal was once hailed as a cheap new way.. suitable for washing machine and other appliances.

have a good look at some Japanese motorcycles gearboxes. the drive dogs have gone internal and the gear is sintered. These handle 100 HP+. hardness of a ball bearing. 3D printing is still in very very early stages. it is " the next big thing".

I have been blown away by the advance of technology. especially CNC and the accompanying advances in metallurgy especially heat treatment. eg: if a precipitation hardening steel is used, new things become viable.

As I dont have a crystal ball, I cannot accuratly predict the future. However, if studying the advances made in the last 50 years, you will see an exponential leap. By inference then, our wildest imaginings will become reality.

most of us look at things through the glasses of current reality. the truly clever person thinks outside the square.

he does not say I cant, he says "why Not". The proof of this statement is progress has advanced very rapidly. What we think of as magic will one day become reality. best wishes Aussie bradley

Does anybody really think a part made from powdered metal can be as strong as a forging, or one made from milling or turning a billet? Perhaps a 3D part may be as strong as a pot metal casting, or the equivalent made from plastic, but otherwise....., IMO, no. Then, there is the question of heat treating to give the part wear resistance. 3D printing will be limited to producing mock-ups and ornamental type parts for the near future. Slick

The short answer is no, I have just seen a short TV program where 12 bore guns were made and tested before being given a gun certificate, they insert a cartilage (not available to the general public) that has been inserted 30% higher charge of gunpowder before being fired in a locked room via a length of string.
Do you think this gun will get a gun certificate by the authorities :?:
 
Ok 3D print now more than capable to print a crude ole Norton engine and everything else upgrades included metal & plastic with intergrated wire loom if desired pluse turbine powered to boot. Someone tell Jay Leno and put in an order as long as not a dastarly HiRyder.

Using 3D printed aluminum 'nodes' in strategic manufacturing, they've created an automobile that weighs in at just 1,400 pounds, and can go from 0-60 MPH in only 2.2 seconds. DM will be producing 10,000 cars per year and also making technology available to any other companies interested. Neat shape for a torpedo car.

I watched a news item on TV a few days ago where a guy in Melbourne had his jaw bone replaced with a titanium one from a 3D printer.
 
The shots of it only showed the jaw bone, I presume he has dentures. He was sitting up in hospital with a very fat face after the surgery.
 
People bone parts have been printed for most a decade now so mainly this jaw bone part is showing off a new level of surgery method more than the printed part.
