I don't fucking get it at all.

To print an object, you'll need a digital model (which you'll have to scan first because using your 3D graphics skills ain't gonna cut it).

So why not just use normal scan and drill/laser cut /hydraulic press techniques instead of buying a scanner plus a 3D printer? If the objective is to produce a 3D object, which both technologies do, what's the difference?

I mean, what makes it so special that previous modelling technologies couldn't do?

Someone enlighten me on this one.

You can create models on Earth and then take them (and printer) to Mars.

The difference between additive and subtractive manufacturing is like night and day. If you've never been involved in manufacturing then I guess it might be hard to grasp the concept?

well a 3d pritner is one sorta thing.. its not efficient on the long run... for manufacture and so.. but there was the zeitgeist movement and the like. so many people in there are people who are poor and this is one thing for everything.. so az al lthe movement according to old world order is infiltrated by the police thus it is well known that police and the like related families make small to medium businesses for themselves and they live comfortably of the system while their groups ar eusually more influential then others.. so anyway.. they seen it as an oportunity to sell their small to medium business related stuff.

thats all the hype about not rocket science.

but i am telling u it will never produce such high quality material as other techniques.

or u need insanely expensive material for all sorta things.

additionally these sorta movements are also a nice opprotunity for the artist females to prostitute themselves there (in the small businesses of the cops usually speaking.. the noncops related small businesses wich would compete possibly with cops are hindered early with things available to them if possible.

I don't know if you are joking or not but this doesn't make any sense.

Invalid parameters bro!

Ok. So that's the thing. Additive v Subractive

I still don't get the hype though.

addictive allow us to save material, more efficient, and what is bad by having ability to rapid prototype?

portability, when object could be printed out nearby resources, and resources could be compacted into user friendly package, then everyone could print out what they needed,

a special casing for handphone, SBC, missing keyboard button, you name it,

and 3D printer price will drop like hell till everybody could own one like refrigerator, oven, smart tv.

i could see whatever the industrial is having, will get mini-scaled and appear in every house,

Ooh nice. This is actually cool. Maybe I'm just behind to understand. Better catch up. So what's the biggest 3d printer (yet)?

I'd love to see it print some kind of a shelter, like a dog house for starting.
OK. I think my mystery has been solved. Thanks

There are 3D printers that can print (with use of concrete) a house:

i am thinking to build one 3D printer,
by harvesting laser printer, inkjet printer stepper motors?

the few ideas i could think of right now,

fridge magnet casing, birthday cake tag,
making object/device casing the most part i guess,
name tag, car plate, laptop casing,

i went to a penang 3D maker shop days ago, it seems to build one, it costs around USD 800 right now,

this kinda device will evolve into chemical printing, dna printing and so on,

They are selling a kit "headache" free. Why bother?

Just curious.


if things could be scavenged, why not?
and it seems cool to create such object using stuffs that people regarded as no value.

Imagine walking into an auto parts store and being like:

Hey I need a new engine head for my obscure car that no parts have been manufactured for in 30 years please

and he being all like

Sorry I don't have that, but if you give me 15mins I can print one out for you

and your all like

Would you print out a part from a custom CAD

and he be all like

Yep, no prob bro
