SRU was just making a proof of concept in the design before they feed the same model into their steel CNC machine.

 

i dont thing 3d printing slides would work well. there is no consistency in the grain of the plastic. it would definitely work for other things though.

Do 3D Printers only print in plastic?

 

How about printers that use metal feedstock ?

its not the same. they use a powdered version of the metal that when "printed" is not welded together but held together with a separate adhesive. its really only good for intricate decorative work (like door handles or small statues) that would be difficult to attain with a CNC machine. they cant bare much weight.

 

from what i have seen, the metal prints are done in a tub or tray with tall walls. the machine lays down a thin sheet of the powdered material and then a nozzle passes over that, dispensing the adhesive. then the machine passes another thin layer of powdered metal over that and so on. then the whole thing is baked to cure the adhesive and the piece is then removed.

Sir naggedalot, that method is called selective laser sintering. From what I understand it can produce parts that are similar to cast metal parts in hardness, but I would hesitate to call it printing. I saw someone make the analogy that SLS is to 3D printing what a blast furnace is to an easy-bake oven, or something like that. I believe there's a company somewhere, possibly Australia that makes suppressors for real guns using SLS.

In case anyone is interested the Daily Mail last week ran an article where the lady writing the article had a miniature replica of herself produced by a shop in London.

 

Unfortunately I've mislaid the copy but, from memory they used 64 cameras to produce a 3D image of her approx 150mm high complete (and this was what astonished me) with eye lashes and the grooves on the ring on her finger.

The machine apparently also 'painted' the figure as it was made.

 

I think she said it took two days and cost £82.

 

Although the service would be unlikely to be useful for airsofters (except geardo's :) 'This is me in my SAS loadout, this is me in my Delta loadout, this is me in my burlesque.....oops!) It does show the rapid advance from specialist companies to High Street.

If its true what Im hearing then the next Windows software will come with 3D scanning!

 

Now thats mainstream.

 

Now who was it that was telling me this will never catch on for the home hobby user? lol

Probably the same person who said they would never make a SA80 for the UK market................:)

3D printers for the home hobby user probably will catch on, but most people don't seem to realise just how many limitations there are to what they can be used for, even with the industrial 3D printers they are largely just used for rapid prototyping due to being pretty rubbish for parts that require any sort of strength and durability, not to mention the sheer time it takes to print a single part. Casting, forging, injection moulding and CNC machining still provide much faster, cheaper and reliable ways of producing parts with the required strength in an actual production enviroment.

 

Think 3D printing is going to be a huge revolution in the manufacture of mass produced injection moulded plastic parts and will replace the old methods? Think again, 3D printing has it's place in prototyping and very short runs but I doubt it'll ever catch up with the existing, highly refined and increasingly efficient production methods.

 

'3D Printers' that produce metal parts using powder and a laser are unlikely to ever get into the reach of the average home hobby user, especially as all the push for home printers is focused on ones that use plastics.

 

For those interested here is a video of parts being produced using titanium powder,

To use the BJ Printer analogy we use in our homes now. :shutup2: Most of our home printers our crp when you compare them to top end production Printers but we will put up with our lower res pic because its a price we can afford and most dont need a high res image anyway.I reckon most 3d printers will be used for food anyway,well I hope so.Im going to get fat just from the waste alone.....
