What most people don’t understand is how simple 3d printing actually is.
You can create by hand a crude version of the same sorts of things a cheap 3D printer makes with a precision glue-gun loaded with low-temp plastic sticks....it’s just tedious and stupid since there are cheap 3D printers.
A 3D printer is a devise that lays down tiny blobs of hot plastic according to a plan generated on a computer. The computer is also a simple tool consisting of little more than a mass of simple on/off transistor switches.
The power behind it all is the marvelous God-given mind of Man. The computer is an amplifier for the mind of man...it is so fast that in a way it almost stops time in its tracks.
Using this amplifier men will be able to repair horrific damage to the human body! Surgeons could do it by hand if they only had the time! They know exactly what needs doing, they just can’t do it quickly enough to keep the tissue viable. They also cannot act at the cellular level to glue cells back together....but this is quickly coming!
3D printing will some day soon begin to negate the need for donor organs as the tech gets good enough to create new organs from a patients own tissue.
Entire new skins will be created.... the ultimate face lift :-)
Cognitive enhancement will become possible by repairing brain cells and even replacing whole sections with your own tissues. Adding digital I/O directly to the brain in a non-invasive way will become possible.
I’m loath to say more since so many cannot get their heads around a technology so advanced and powerful that will soon arrive.
I’m a tech guy... I see no possibility that these things will not come to pass.
Spot on. In the architectural and civil engineering fields, site models were constructed of cardboard, illustration board, and later foam layers tedious cut from topograhic map overlays and glued together like a layer cake. Result was a very heavy model. 3D printing means that the model can become a light weight shell as well as freeing professional staff from grunt work better utilized in other tasks.
Other modeling uses as well.
