3D Scanning on Vacations – Scancation tips from Bre Pettis #3DPrinting #3DThursday
I scanned a few of my favorite stones and ran them through 123D Catch which makes a 3D model from up to 70 photos of the object. It’s pretty cool to think that yesterday I was walking among these stones and today I’m printing them out on the MakerBots in my office.
It’s interesting to note that this feels a lot like the old days of vacation film photography. The process of processing the photos into a 3D model feels a lot like when I used to develop celluloid film after a vacation.
Someday, printing 3D models will be normal for everyone, for now, it’s just normal for all the MakerBot operators in the world.
If you decide to go on your own scanning vacation, aka scancation, here’s my process and tips for acquiring models.
Lighting conditions matter. A cloudy sky is much better than a sunny one so that you can get all the details of your subject.
Fill the frame, but make sure to leave some area around the object in the picture. 123D Catch uses reference points in the object to make eve
rything fit together.
Use all 70 pictures allowed by the software. The more pictures, the better the scan.
Scan weird things. Sometimes the most iconic stuff of a location isn’t the most obvious. Some friends of mine scanned all of Canal St. in NYC and said the interesting parts were the giant piles of trash bags which are one of the local overlooked pieces of landscape art.
Don’t forget the top view. If you are capturing a subject that is tall, do your best to get above it and take a picture. A quadcopter could be handy for that.
Fix it up with Netfabb. After I upload the photos into the 123D Catch online portal, then I use Netfabb basic to slice off all the weird parts and cut a flat bottom onto the object.
Make sure to upload your scans to Thingiverse. We can all make models of your SCANCATION.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
