so cool I love watching this so much
Its so cool how they were able to create such tiny things with so many different parts.
Chips have a lot of details
hello from Texas!!! I love science live
hello here for science live
Hello from Texas!!
Hello from Alaska
Hello from Indiana!!
If we make a faster computer how fast would you think it will be?
Hello from NJ
Hi from Arkansas
hello from Maryland
Hi from Florida 🙂
hello from Nigeria
Federico’s work is very impressive!
Really enjoy all of Tobias’ topics, learn a lot from it all!
Excited for science live tonight!!
Loving it!!
3d printing is very interesting, being able to print a variety of things that you may need for convenience can just be printed. If you want new decorations you can design and then 3d print them to your liking.
my favorite part of wednesdays!
Hi from Ohio!! Happy to watch
3D printing is fascinating.
Very cool video
thats impressive with that idea he had
This is so amazing i love these lessons I learn something exciting every week.
I really liked Dr. John’s part about 3-D print printing
That is probably the best response to being called crazy that I can think of.

Hi from MI
Hi everyone!! So blessed to be able to join all of you!
Hey from Va, love watching these lives!
It’s nice to see them find other ways to 3D print stuff. Especially ways that can make 3D things at lighting speed.
hello from Illinois
Such a great day to learn!From nebraska!
Good live
Hello from TN.I love science live and if you love it say it. My sister is going to have a baby i’m going to be a aunt
It’s nice to see them find other ways to 3-D print stuff. Especially ways that can make 3-D things at lighting speed.

My brother wants a 3d printer
I have a small 3d printer i am saving my money for a bigger one i love making so many cool trinkets !
3D printers are really cool, but I’d just use one of those pens with the hot ink coming out of it lol.
Wow never knew that 3d printers were that slow
Hello from Florida!!
That is so fast. Wow
I loved learning about the fastest way to print, so cool!!
