3-D printing can change the world. It could help end a lot of the world’s problems, such as world hunger and perhaps poverty too, but only if used in the right way. Most people 3-D print small objects, like name tags. But, what if every household had a food 3-D printer? What if 3-D printed houses are made and sold? It could solve a lot of problems. Overall, 3-D printing is very useful.
I thought it was so cool how different the process of creating lumber is now than back the the 1900’s! One thing I noticed that was different was that the process back in the 1900’s was way more dangerous than it is now. I also noticed that it looked a lot easier to do with today’s modern technology, rather than how they used to do it; cutting the trees down by hand, having to transport the trees by putting them in a truck, then have them lifted by helicopter, and then putting them on train, and then finally delivering them into the saw mill’s water. Then, they have to take it out of the pond manually and move it through this big saw. Comparing to the modern way, which is basically that whole process, but using machines for all of it, it is so much harder. Overall, I thought it was fascinating how much the process changed.
