Printing in 3D

[posted @ 10:20 pm by techwizard33]
A few days ago, a friend showed to me his

3D printer. I wanted to see it because I
might buy for my son one. The printer was
smaller than I expected. It cost my friend a

lot of money, too, but apparently the price
is coming down. He turned on it, so I was
able to see how it worked. My friend uses
his computer to design items for other
companies. To test his ideas, he needs to

try out them. Making an item to test used A 3D printer prints a model plane.
to be a long process, but now my friend can make one quickly with his 3D printer. It seems
incredible! I think I will buy one!

I agree. These sound great. The other day I ran a friend into when I was downtown. She
does research on historical objects. She does a lot of work to the Smithsonian Institution in
Washington, DC. In the past, she had to travel twice a month to examine the real objects at

the Institution, but recently she also bought a 3D printer. Now the Institution sends to her
the exact measurements of an object and she prints out it at home. It’s great!
