This past weekend I worked a 3d printing booth at my kids’ elementary school carnival. It was wonderful to watch scores of 6 to 10 year olds creating in Tinkercad. I’m still catching up on printing their work.
Why it’s in the news again: While the kids’ were building the parents wanted to talk 3d printing. Guns and 3d printing. Senator Schumer (D-NY) is seeking an extension to the 25 year old Undetectable Weapons Act. This act bans manufacturers from creating weapons that are undetectable by metal detectors. The frequently referenced 3d printed Liberator handgun plans do include provisions for the owner to install a metal slug thus making the weapon detectable. That bit of the installation process is in control of the builder. And the folks at Defense Distributed aren’t the only producers of 3d printed plans for guns or gun parts.
I’ve been using a Makerbot Replicator dual for a year and a half and Continue reading
3d printed guns are in the news again. It goes like this:
“Hey I heard you have a 3d printer. Have you printed a gun yet?” Yawn.
So I offer you these cool stories to turn the conversation back to 3d printing greatness. Then you can say, “Yeah the 3d printed gun is something but have you heard about…” Continue reading
The benefits of bringing a 3D printer into your classroom can be real and immediate. And I will get to them. But first a word: patience. You have to give yourself and your students the freedom to be patient with the process and the machine.
1. Common core and 3d printing – in the California Common Core Standards for Geometry item #4 is “Model with mathematics”. So much of my conversation around 3d modeling using everyday geometric terminology. On the first day of our work with Tinkercad (cloud based 3d modeling) I show students how to free rotate an object or to rotate it in increments of 45 degrees.
There is also a significant need for Continue reading
