[..] In a few years time, add conducting metal to plastics and you almost have circuit boards. (silicon chips is another matter) [..]
it's rubbish
Working "silicon chips" and circuit boards have been printed. They're not silicon and they're not chips, but they are the same components and circuitry and they have the same functionality. Better in some ways, as they can be printed onto a variety of materials and the resulting components can have some degree of flexibility. The cost is staggering at the moment, but it's been done as research.
Home printing of functional complex objects is going to become an issue, perhaps more so than unauthorised copying of music, video and games. People still widely buy those things, but when cost scales up I think fewer people will do so. If it gets to stage of examples like £300 to buy a legit copy of a games console or £30 to print your own identical copy, or your own copy cased exactly as you want it, I think fewer people will go for the legit one.
Considering a £300 console (e.g. PS3) is generally sold at a loss, do you really think an end user without advanced manufacturing processes is going to be able to make one for 1/10th the cost?
You wouldn't copy a waterpump,
Downloading a kettle is THEFT!
CNC/cad is the same as 3d printing.
No it's not. Availability, yes, but they are completely different types of machining.
this is where the talk gets carried away with itself - forget about the materials - using current technology its not even remotely possible to print certain components. How would you print something as simple as a metal spring for example??
John Connor: I need a minute here. You're telling me that this thing can imitate anything it touches?
The Terminator: Anything it samples by physical contact.
John Connor: Get real, like it could disguise itself as a pack of cigarettes?
The Terminator: No, only an object of equal size.
John Connor: Why doesnt it become a bomb or something to get me?
The Terminator: It cant form complex machines, guns and explosives have chemicals, moving parts, it doesn't work that way, but it can form solid metal shapes.
John Connor: Like what?
The Terminator: Knives and stabbing weapons.
I think Glaucus was alluding to the fact CNC has been about forever and allows you to make many things "at home" you'd otherwise have to buy. CNC hasn't destroyed the world, neither will 3D printing. Cost, practicality and peoples apathy see to that![]()
surely at the moment all you are printing anyway is a 3d image of the object..a representation of the object itself..you can print something that looks like a kettle but it has no functionality because it has no heating element, no wiring, no electrical contacts.
yep - simple stuff only.
One day it will be possible to buy the cheapest 3d printer on the market and print the parts to make the largest and best 3d printer on the market.
3d printer manufacturers are going to go bust pretty quickly too once someone buys one and starts printing copies of that same printer.![]()
if I can scan it and print it myself then tough luck. There is no way that will ever be policed.
Printing based on sintered metal or ceramic powder works fine. Not as cheap as additive based plastic.
I'm currently attempting to print things in abs then change the material to epoxy via casting. I'm pretty sure that's going to work. It wouldn't be difficult to cast a high temperature epoxy/steel particle composite instead. That would make a usable gun I think. I've no interest in making a gun, I'm trying to make a robot hand
Does anyone have a decent reference for photos -> CAD? I'm trying the Autodesk software at present with limited success. CAD -> plastic is straightforward, but object (e.g. a bone) to CAD is less so.
